Abstract
An imaging apparatus according to an embodiment includes a pixel array unit (101) including a plurality of pixels arranged in a matrix array, each of the pixels generating a pixel signal corresponding to light received by exposure, the pixel array unit acquiring image data based on each of the pixel signals respectively generated by the plurality of pixels, a compression unit (1020) configured to compress a data amount of the image data to generate compressed image data, a signature generation unit (1021) configured to generate signature data based on the compressed image data; and an output unit (104,131,132) configured to output the image data and authenticity proof data obtained by adding the signature data to the compressed image data.

An imaging apparatus comprising:
- an image sensor including a plurality of pixels arranged in a matrix array, each of the pixels generating a pixel signal corresponding to light received by exposure, the image sensor acquiring image data based on each of the pixel signals respectively generated by the plurality of pixels, the image data including first frame data and second frame data, the first frame data and the second frame data representing consecutive frames;
- and
- one or more electronic processors configured to:
- compress a first data amount of the first frame data to generate first compressed image data;
- compress a second data amount of the second frame data to generate second compressed image data;
- generate signature data based on the second compressed image data and not the first compressed image data, the signature data serving as authenticity proof data for both the first frame data and the second frame data;
- and
- output the image data and authenticity proof data obtained by adding the signature data to the second compressed image data.
An imaging method executed by a processor, the imaging method comprising:
- an acquisition step of acquiring image data by each of pixel signals generated by a plurality of pixels, the image data including first frame data and second frame data, the first frame data and the second frame data representing consecutive frames, the pixel signals being acquired by an image sensor including the plurality of pixels arranged in a matrix array, each of the pixels generating the pixel signal corresponding to received light;
- a first compression step of compressing a first data amount of the first frame data to generate first compressed image data;
- a second compression step of compressing a second data amount of the second frame data to generate compressed image data;
- a signature generation step of generating signature data based on the second compressed image data and not the first compressed image data, the signature data serving as authenticity proof data for both the first frame data and the second frame data;
- and
- an output step of outputting the image data and authenticity proof data obtained by adding the signature data to the second compressed image data.
