`
`Notice of Pre-AIA or AIA Status
`
`The present application, filed on or after March 16, 2013, is being examined under the
`
`first inventor to file provisions of the AIA.
`
`DETAILED ACTION
`
`This is in response to applicant’s amendment/response filed on 10/10/2019, which has
`
`been entered and made of record. Claim(s) 1 has been amended. Claim(s) 6 is canceled, and
`
`claim(s) 8 is added. Claim(s) 1—5, 7—8 are pending in the application. The rejections under 35
`
`USC § 112(b) to claims 1—5, 7 has/have been withdrawn in view of the amendment. The
`
`objection to claim 1 has been withdrawn in view of the amendment.
`
`Priority
`
`Acknowledgment is made of applicant's claim for foreign priority based on an application
`
`filed in Japan on 3/30/2017. It is noted, however, that applicant has not filed a certified copy of
`
`the JP2017068369 application as required by 37 CFR 1.55.
`
`Claim Objections
`
`Claim 1 is objected to because of the following informalities: “by the first gradation
`
`converter” in line 22 might be corrected as “by the second gradation converter”. Appropriate
`
`correction is required.
`
`Claim Rejections - 35 US C § 103
`
`In the event the determination of the status of the application as subject to AIA 35 U.S.C.
`
`102 and 103 (or as subject to pre—AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the
`
`statutory basis for the rejection will not be considered a new ground of rejection if the prior art
`
`relied upon, and the rationale supporting the rejection, would be the same under either status.

`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness
`
`rejections set forth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not
`identically disclosed as set forth in section 102, if the differences between the claimed invention and the
`prior art are such that the claimed invention as a whole would have been obvious before the effective
`filing date of the claimed invention to a person having ordinary skill in the art to which the claimed
`invention pertains. Patentability shall not be negated by the manner in which the invention was made.
`
`Claim(s) 1 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hirata (US
`
`20100002018 A1) in view of Esashi et al. (US 20170295300 A1), and further in view of Marcu
`
`et al. (US 20120281008) and Safaee-Rad et al. (US 20120056911).
`
`Regarding claim 1, Hirata discloses A liquid crystal display device in Which a plurality
`
`of display panels are disposed While overlapping each other, and an image being displayed
`
`on each of the display panels (Hirata, “[0056] In the liquid crystal display device, when a first
`
`liquid crystal panel is the top most one of the stacked liquid crystal display panels, the first liquid
`
`crystal panel is a color liquid crystal panel and at least one of the other stacked liquid crystal
`
`display panels is a black and white liquid crystal panel”. “[0206] The first and second panels
`
`may be fed with identical image signals, or signals that are associated but different”), the liquid
`
`crystal display device comprising:
`
`a first display panel that displays a first image based on m-bit input image data; a
`
`second display panel that displays a second image based on the m-bit input image data
`
`(Hirata, fig.7. “[0253] The following deals with a concrete example of a driving method in the
`
`display controller of the liquid crystal display device 100 arranged as above, with reference to
`
`FIG. 7. Assume 8 —bit (256 gradation) inputs and 8 —bit liquid crystal drivers. [0256] The first and
`
`second panels handle 8—bit data, and the resultant outputs are also 8—bit images. Each of the
`
`output images corresponds to each of the input signals one to one, so that the input images are
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 4
`
`faithfully reproduced.” Therefore, each of the first and second display panels displays an image
`
`based on the 8—bit input signal); and
`
`an image processor including a first gradation converter that converts a gradation
`
`of the m-bit input image data into an m—bit gradation based on a first gamma characteristic
`
`of the m—bit driving first display panel (Hirata, “[0253] The following deals with a concrete
`
`example of a driving method in the display controller of the liquid crystal display device 100
`
`arranged as above, with reference to FIG. 7. Assume 8 —bit (256 gradation) inputs and 8 —bit
`
`liquid crystal drivers. [0254] The panel driver circuit (1) of the display controller section carries
`
`out drive signal processing such as .gamma.—correction and overshooting with respect to an input
`
`signal (video source) so as to output 8—bit gradation data to a source driver (source driving
`
`means) of the first panel.” Therefore, the gamma correction corresponds to the gradation
`
`conversion based on a gamma characteristic), a second gradation converter that converts a
`
`gradation of the m-bit input image data into an ml-bit (m1>= m) gradation based on a
`
`second gamma characteristic of the second display panel (Hirata, “[0253] The following
`
`deals with a concrete example of a driving method in the display controller of the liquid crystal
`
`display device 100 arranged as above, with reference to FIG. 7. Assume 8 —bit (256 gradation)
`
`inputs and 8 —bit liquid crystal drivers. [0255] Meanwhile, the panel drive circuit (2) carries out
`
`signal processing such as .gamma.—correction and overshooting so as to output 8—bit gradation
`
`data to a source driver (source driving means) of the second panel.” Therefore, ml=m=8 in this
`
`embodiment).
`
`On the other hand, Hirata fails to explicitly disclose but Esashi discloses an n-bit (n<m)
`
`driving first display panel that displays a first image based on m-bit input image data; an
`
`image processor including a first gradation converter that converts a gradation of the m-bit
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 5
`
`input image data into an n-bit gradation based on a first gamma characteristic of the n-bit
`
`driving first display panel, wherein the n-bit driving first display panel displays the first
`
`image based on the n-bit input image data in which the gradation is converted by the first
`
`gradation converter (Esashi, fig.4. “[0035] In the case of displaying the generated X—ray image
`
`on the display 106, the display system receives the multi—gradation X—ray image, applies a color
`
`reduction LUT for display, and performs monitor gamma processing to convert the gradation of
`
`the X—ray image from "10 —bits" to "8 —bits". A video card putouts the "8 —bits" X—ray image from
`
`the display 106.” Therefore, n=8, and m=10 in this embodiment);
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Hirata and Esashi. That is, replacing the gamma
`
`correction of the first display panel of Hirata with the gamma processing of Esashi. The
`
`motivation/ suggestion would have been in the case of displaying the X—ray image having a
`
`larger number of gradation levels than the number of gradation levels displayed by the display
`
`106, the X—ray diagnostic apparatus 1 simply thins the number of gradation levels according to
`
`the LUT kept in the display 106, and displays the X—ray image (Esashi [0035]).
`
`On the other hand, Hirata in View of Esashi fails to explicitly disclose but Marcu
`
`discloses an n-bit driving second display panel that displays a second image based on the m-
`
`bit input image data; and a second gradation converter that converts a gradation of the m-
`
`bit input image data into an ml-bit (m1>= m) gradation based on a second gamma
`
`characteristic of the n-bit driving second display panel, and an extension processor that
`
`performs extension processing of extending gradation expression with the 11 bits on the
`
`input image data converted into the ml-bit gradation, and the n-bit driving second display
`
`panel displays the second image based on n-bit input image data in which the gradation is
`
`

`Page 6
`
`converted by the first gradation converter in RGB format, subjected to the extension
`
`processing (Marcu, fig.3 and fig.5, “[0008] the so—called gamma correction may also include
`
`what is referred to in the field as gray tracking compensation. [0045] Dithering circuit 30'
`
`reduces the input 12 bits of data (per pixel, per color channel) to 8 bits as is conventional since
`
`typically the display driver (not shown) can only accept these 8 bits. Further, the reference here
`
`to the number of bits refers to each color channel such as red, where typically there are three
`
`color channels——red, green, blue (RGB). [0046] FIG. 3 shows the result of the process of FIG. 2;
`
`where additionally the gamma and gray tracking correction are carried out in element 46 at 40.
`
`Here the gamma and gray tracking compensation 40 add two bits (per color channel per pixel)
`
`and the dithering component 30 reduces its 12 —bit input to an 8 —bit output for each color
`
`channel.” Therefore, the dithering of Marcu corresponds to the extension processing. M=10,
`
`m1=12, and n=8 in this embodiment).
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Marcu into the combination of Hirata and
`
`Esashi. That is, replacing the controller of the process in fig.3 of Marcu with the processor of the
`
`second display panel of Hirata. The motivation/ suggestion would have been to provide Method
`
`and apparatus for adjusting the display characteristics of an electronic display, such as a
`
`computer or television display. Thereby when the display is in use, it performs compensation for
`
`white point, gray tracking and gain correction as the display warms up, each time it is powered
`
`up or when its thermal operation conditions change (Marcu, abstract).
`
`On the other hand, Hirata in View of Esashi and Marcu fails to explicitly disclose but
`
`Safaee—Rad discloses a first signal converter that converts the input image data having an
`
`RGB format into the input image data having an HSV format and a second signal
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 7
`
`converter that converts the input image data converted into the HSV format into the input
`
`image data having the RGB format (Safaee—Rad, fig. 7. “[0093] In some examples, a color
`
`space conversion unit 703 may convert the image to another color space, e. g., from sRGB to
`
`HSV, which expresses image data in hue, saturation, and value (or brightness). [0095] Once the
`
`contrast has been enhanced according to the lookup table from ABL unit 711, the image may be
`
`converted back from the "hue, saturation, brightness" (HSV) space to the standard RGB (sRGB)
`
`color space (as most displays accept RGB values) in color space conversion unit 719.”
`
`Therefore, the input image 701 of Safaee—Rad corresponds to the m—bit input image data).
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Safaee—Rad into the combination of Hirata and
`
`Esashi, Marcu, to include all limitations of claim 1. That is, adding the RGB/HSV conversion
`
`and the HSV/RGB conversions of Safaee—Rad prior to and after the gradation conversion of the
`
`first display panel of Hirata, Esashi and Marcu. The motivation/ suggestion would have been
`
`Conversion to HSV, for example, allows for HSIC (hue, saturation, intensity, contrast)
`
`adjustments in response to user selections 707. HSIC unit 705 may adjust hue, saturation,
`
`intensity, and contrast of the incoming image, in response to user selections 707 (Safaee—Rad
`
`[0093]).
`
`Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hirata in view
`
`of Esashi, Marcu and Safaee-Rad, and further in View of Sawabe (US 20090284518).
`
`Regarding claim 2, Hirata in view of Esashi, Marcu and Safaee—Rad discloses The liquid
`
`crystal display device according to claim 1, wherein the first gradation converter converts the
`
`m-bit gradation into the n-bit gradation using a first gamma value, the second gradation
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 8
`
`converter converts the m-bit gradation into the ml-bit gradation using a second gamma
`
`value, has been disclosed.
`
`On the other hand, Hirata in View of Esashi, Marcu and Safaee—Rad fails to explicitly
`
`disclose but Sawabe discloses the first gamma value and the second gamma value are equal
`
`to each other (Sawabe “[0229] As described above, in the present embodiment, examples are
`
`made under a condition where both of two panels are set to ".gamma.=1.1" independently. The
`
`present invention, however, is not limited to this. Two panels may differ in . gamma. value in
`
`such a manner that the . gamma. value becomes " .gamma.=2.2" as a whole.”).
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Sawabe into the combination of Hirata and
`
`Esashi, Marcu and Safaee—Rad. That is, applying the gamma value setting of Sawabe to the dual
`
`display panels of of Hirata, Esashi, Marcu and Safaee—Rad. The motivation/ suggestion would
`
`have been to provide a liquid crystal display device and a driving method thereof, both of which
`
`can reduce a response period. (Sawabe, [0230]).
`
`Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hirata in View
`
`of Esashi, Marcu and Safaee-Rad, and further in View of Hayashi (US 20150210100).
`
`Regarding claim 3, Hirata in View of Esashi, Marcu and Safaee—Rad discloses The liquid
`
`crystal display device according to claim 1.
`
`On the other hand, Hirata in View of Esashi, Marcu and Safaee—Rad fails to explicitly
`
`disclose but Hayashi discloses the extension processing is dithering of extending the
`
`gradation With an average of an area direction (Hayashi, “[0099] In this case, as one example,
`
`an average of gradation values of pixels in the region within the image data to which the dither
`
`mask 210 is applied is obtained and used as a gradation value D”).
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 9
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Hayashi into the combination of Hirata and
`
`Esashi, Marcu and Safaee—Rad. That is, applying the dithering of Hayashi to the dual display
`
`panels of Hirata, Esashi, Marcu and Safaee—Rad. The motivation/ suggestion would have been to
`
`reduce resources required for a dither mask and prevent deterioration of gradation due to dither
`
`processing (Hayashi, [0007]).
`
`Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hirata in view
`
`of Esashi, Marcu and Safaee-Rad, and further in view of Sakaigawa et al. (US 20150294441
`
`A1).
`
`Regarding claim 4, Hirata in view of Esashi, Marcu and Safaee—Rad discloses The liquid
`
`crystal display device according to claim 1.
`
`On the other hand, Hirata in view of Esashi, Marcu and Safaee—Rad fails to explicitly
`
`disclose but Sakaigawa discloses the extension processing is frame rate controlling of
`
`extending the gradation with an average of a time axis direction (Sakaigawa “[0115] The
`
`FRC 16 performs a dithering process by switching plural frames which make up one gradation
`
`image at a high speed, and outputs a signal including bits the number of which is smaller than
`
`that of bits included in a signal outputted from the reverse gamma conversion section 14. [0116]
`
`The FRC 16 performs a dithering process by displaying one gradation image while switching n
`
`frames. At this time M.times.M pixels in the gradation image are considered as one block for
`
`which luminance representation is changed. Positions at which M.times.M pixels light are
`
`changed in each of the 11 frames”).
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Sakaigawa into the combination of Hirata and
`
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 10
`
`Esashi, Marcu and Safaee—Rad. That is, applying the FRC of Sakaigawa to the extension
`
`processing of Hirata, Esashi, Marcu and Safaee—Rad. The motivation/ suggestion would have
`
`been gradation errors convoluted into data outputted from the reverse gamma conversion section
`
`14 are spatially dispersed (Sakaigawa, [0125]).
`
`Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hirata in view
`
`of Esashi, Marcu and Safaee-Rad, and further in view of Kobayashi (US 20160347006 A1).
`
`Regarding claim 5, Hirata in view of Esashi, Marcu and Safaee—Rad discloses The liquid
`
`crystal display device according to claim 1.
`
`On the other hand, Hirata in view of Esashi, Marcu and Safaee—Rad fails to explicitly
`
`disclose but Kobayashi discloses the extension processing is smoothing of smoothing a
`
`boundary Where luminance changes using an average value filter (Kobayashi, “[0046] For
`
`example, a moving average filter, a Gaussian filter, or a median filter may be used to smooth and
`
`blur the boundary region 43.”).
`
`It would have been obvious to one of ordinary skill in the art before the effective filing
`
`date of the claimed invention to have combined Kobayashi into the combination of Hirata and
`
`Esashi, Marcu and Safaee—Rad. That is, applying the moving average filter of Kobayashi to the
`
`extension processing of Hirata, Esashi, Marcu and Safaee—Rad. The motivation/ suggestion
`
`would have been to provide a mathematical tool to smooth and blur the boundary region
`
`(Kobayashi [0046]).
`
`Allowable Subject Matter
`
`Claim 7 is objected to as being dependent upon a rejected base claim, but would be
`
`allowable if rewritten in independent form including all of the limitations of the base claim and
`
`any intervening claims.

`
`Page 11
`
`The following is a statement of reasons for the indication of allowable subject matter:
`
`Regarding claim 7, it recites, the first gamma value and the second gamma value are
`
`0.5, and a combined gamma value of a display image in which the first image and the
`
`second image are combined is 2.2.
`
`None of the prior arts on the record or any of the prior arts searched, alone or in
`
`combination, renders the above claimed invention obvious.
`
`Claim 8 is allowed.
`
`The following is an examiner’s statement of reasons for allowance:
`
`Regarding claim 8, it recites, inter alia, the first gamma value and the second gamma
`
`value are 0.5, and a combined gamma value of a display image in which the first image and
`
`the second image are combined is 2.2.
`
`None of the prior arts on the record or any of the prior arts searched, alone or in
`
`combination, renders the above claimed invention obvious.
`
`Response to Arguments
`
`Applicant's arguments filed 10/10/2019 have been fully considered but they are not
`
`persuasive.
`
`The applicant submits: The references, even when considered in combination, do not
`
`suggest the features of claim 1 discussed above. Even if Hirai discloses a liquid crystal display
`
`device including two liquid crystal panels that are stacked with each other, Hirai does not suggest
`
`a display device in which, in the gradation conversion processing for the individual panels, signal
`
`data of different formats are input into each gradation converter. Esashi and Marcu are cited for
`
`purposes unrelated to this aspect of claim 1 and do not remedy the deficiencies of Hirai. The
`
`rejection refers to Saface—Rad for features concerning RGB and HSV formats. However, Fig. 7
`

`

`Application/Control Number: 15/942,073
`Art Unit: 2611
`
`Page 12
`
`and paragraphs [0093] and [0095] of the reference, cited for support by the rejection, do not
`
`suggest that different formats should be applied to different gradation converters in the same
`
`display device. Therefore, Saface—Rad also does not remedy the deficiencies of Hirai and the
`
`rejection should be Withdrawn (Remarks, page 7, 2‘101 paragraph).
`
`The examiner respectfully disagrees. Hirata ([0313]) discloses “The analogue RGB
`
`signals are supplied to the A/D converter 502, and converted into digital RGB signals. The
`
`digital RGB signals are then sent to the liquid crystal controller 503.” Therefore, the input signal
`
`is in RGB format. When Saface—Rad is combined with Hirata, Esashi and Marcu, the conversions
`
`of RGB—>HSV and HSV->RGB are added prior to and after the gradation conversion of the first
`
`display panel of Hirata, Esashi and Marcu. Therefore, the input signal for gradation conversion
`
`in the first display panel is HSV format, While the input signal for gradation conversion in the
`
`second display panel is RGB format. Therefore, the combination of Hirata, Esashi and Marcu,
`
`Saface—Rad teaches all limitations of claim 1.
