Claim Rejections - 35 USC § 103
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.
Claims 1-2, 15-16, and 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Chen (Composite Templates for Cloth Modeling and Sketching) in view of Zhang (US 20200134890).
Regarding claim 1, Chen teaches an image processing method, comprising:
Acquiring a first image drawn for a drawing object, wherein the drawing object is correspondingly split into a plurality of sub-objects, the first image is acquired by merging the plurality of sub-objects respectively drawn on a plurality of sub-canvases, and each of the plurality of sub-canvases is used for drawing one corresponding sub object (Page 1, Column 2, Paragraph 8, The remaining graph (Fig.2.d) is decomposed into a number of subgraphs for cloth components (Fig. 2.e));
Generating, according to the second image, a material object to which the drawing object corresponds, and mounting the material object to a corresponding position of a target object (Page 2, Paragraph 1, These subgraphs have “bonds” that tell them who to link with to compose bigger structures (see Fig. 6), and they are combined using the context information to form a wide variety of cloth configurations).
While Chen fails to disclose the following, Zhang teaches:
Determining, for a first pixel in the first image, according to a target magnification, a pixel area block to which the first pixel is mapped in a second image, determining target pixel values of second pixels in the pixel area block, and obtaining the second image after magnification according to the target pixel values of the second pixels in the pixel area block (Paragraph 311, the processing of adaptively adjusting the resolution of the canvas further includes performing image processing on the canvas to increase the resolution of the canvas; Paragraph 313, After the terminal apparatus triggers the adaptive adjustment of the resolution of the canvas, color values of the added pixel points of the canvas need to be determined. Image interpolation is a most common method in which the color value of an interpolated pixel point can be calculated according to the color values of the points adjacent to it in the canvas);
Zhang and Chen are considered to be analogous to the claimed invention because they are in the same field of image rendering. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Chen to incorporate the teachings of Zhang and determine a corresponding pixel in an image after magnification and determine the value. Doing so would allow for maintaining or enhancing the resolution of the image after zooming in (Zhang, Paragraph 311).
Apparatus claim 15 and CRM claim 18 correspond to method claim 1. Therefore, claims 15 and 18 are rejected for the same reasons as used above.
Regarding claim 2, the combination of Chen and Zhang teaches the image processing method according to claim 1, further comprising:
Presenting the plurality of sub-canvases in response to a drawing object template selected for the drawing object, the plurality of sub-canvases corresponding to the drawing object template (Zhang, Paragraph 276, When the user has supplemented details to one fish and wants to switch to the next fish for supplementing details, the user can see the button for switching between objects after raising the pen to a preset height); and
Determining a sub-canvas currently operated in response to a switching operation for the plurality of the sub-canvases, receiving a drawing operation on the sub-canvas currently operated, and obtaining a target pattern drawn on the sub-canvas currently operated (Zhang, Paragraph 276, Paragraph 276, switching from the drawing object A to the drawing object B, so that the user can select to draw one fish having an approximate morphology).
Zhang and Chen are considered to be analogous to the claimed invention because they are in the same field of image rendering. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Chen to incorporate the teachings of Zhang and switch between drawing canvases. Doing so would greatly reduce time required for changing the pen and designing, and the efficiency and quality of drawing are improved (Zhang, Paragraph 276).
Apparatus claim 16 and CRM claim 19 correspond to method claim 2. Therefore, claims 16 and 19 are rejected for the same reasons as used above.
Claims 3-4, 9, 13-14, 17, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Chen in view of Zhang as applied to claims 1-2, 15-16, and 18-19 above and further in view of Joon-Ki (US 20090238488).

Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of Chen and Zhang to incorporate the teachings of Joon-Ki and determine an edge or corresponding pixel values for peripheral pixels of a first pixel. Doing so would allow for increasing the resolution of the zoomed in image while accounting for the edges of the images.

It is desirable to determine the size of the filtering window 330 as 5.times.5 pixels in order to rapidly perform a computing operation while sufficiently considering edge directions);
Determining an initial pixel value of a corresponding second pixel to the target direction in the pixel area block according to the pixel value of the first pixel in response to an edge pixel in the target direction not existing (Joon-Ki, FIG. 3 illustrates interpolation points 350 respectively corresponding to cross points other than cross points at which pixels 340 of an image frame 310 are located among cross points of a lattice filtering window 330 having a to-be-interpolated pixel 320 of the image frame 310 at the center thereof.

The weights are inversely proportional to the distances between the pixels and the interpolation point).

When a gradient value corresponding to the horizontal direction is calculated, for instance, the gradient calculator 111 respectively sums up pixel values of the pixels A, B and C and pixel values of the pixels D, E and F and divides the summed values by 3 to obtain averages of the summed values). Note: Joon-Ki teaches a calculation to determine target pixel values that may determine that the target pixel value is equal to the first pixel value. Additionally, the initial value may be assigned for efficient processing speed.
