Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1 is rejected under 35 U.S.C. 102 (a)(2) as being anticipated by US20160182873 (hereinafter referred to as Sumiyoshi).
Regarding claim 1, Sumiyoshi teaches A correction method for correcting a projection image projected on a planar surface by a projector, comprising: acquiring a first captured image obtained by imaging of the projection image and the planar surface by an imaging device in a first period [See paragraph 0064 where the acquisition unit obtains a first photographed image of a projected pattern (projected image) image and a projection surface. See also Fig 14 where the projection surface (12) is flat];

acquiring a second captured image obtained by imaging of the projection image and the planar surface by the imaging device in a second period after the first period [See paragraph 0064 above where a second image is obtained by photographing the projected image with a second pattern and the projection surface. See also 0065 where the projection apparatus for the first and second photographed image are the same, indicating that that the images were taken at two different times, with the second image being photographed after the first];

extracting a first feature point and a second feature point of the planar surface in the first captured image [See 0069 where coordinates are extracted from the first extraction unit and Fig. 32 where a first and second feature point can be obtained from the image]

The DN calculation happens are part of the identifying unit as shown in Fig. 19];

and correcting a position of the projection image with respect to the planar surface in the second period to a position of the projection image with respect to the planar surface in the first period based on a set of the first feature point, the second feature point, and the first normal vector and a set of the third feature point, the fourth feature point, and the second normal vector [see paragraph 51 where the feature points, and the norm vectors (calculated as part of the image processing apparatus) from both the first and second photographed images are used to correct the position projection image. See also the abstract].

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 4 is rejected under 35 U.S.C. 103 as being unpatentable over Sumiyoshi in view of KR101273534B1 (hereinafter referred to as Yoon).
Regarding claim 4, Sumiyoshi teaches extracting the first and second feature point, and corresponding third and fourth feature point [see paragraph 0214]

Sumiyoshi does not explicitly teach that the feature points are detachable physical markers that reflect light attached to a planar surface
Yoon does teach using removable reflective markers as feature points for projection correction [See description of Yoon paragraph 8 where physical light reflecting markers are placed as feature points as a process to automatically perform screen correction].

Therefore, it would have been obvious to one with ordinary skill in the art before the effective filing date to combine the projection correction of Sumiyoshi with using physical feature markers as feature points of Yoon so that the screen correction can be performed automatically. Rather than using projected pattern image as the feature as described in Sumiyoshi, instead, using a physical marker offers another method to perform the correction.
Allowable Subject Matter
Claims 2 and 3 are 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.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
