Imaging device, signal processing device, signal processing method, program, and imaging apparatus

A signal processing device comprising:

• a flicker detection unit that performs flicker detection on a basis of at least one of a plurality of detection images or a plurality of restored images restored from the respective detection images, the plurality of detection images being generated for a plurality of detection regions on a basis of detection signals output from pixels in the plurality of detection regions disposed in different rows a pixel region that is sequentially exposed row by row,
• a plurality of pixels being arranged in a row direction and a column direction in the pixel region,
• the plurality of pixels including a pixel that receives incident light and outputs one detection signal indicating an output pixel value modulated depending on an incident angle of the incident light, the incident light entering from an object via neither an imaging lens nor a pinhole.

A signal processing method comprising:

• performing flicker detection on a basis of at least one of a plurality of detection images or a plurality of restored images restored from the respective detection images, the plurality of detection images being generated for a plurality of detection regions on a basis of detection signals output from pixels the plurality of detection regions disposed in different rows in a pixel region that is sequentially exposed row by row,
• a plurality of pixels being arranged in a row direction and a column direction in the pixel region,
• the plurality of pixels including a pixel that receives incident light and outputs one detection signal indicating an output pixel value modulated depending on an incident angle of the incident light, the incident light entering from an object via neither an imaging lens nor a pinhole.

A non-transitory computer readable medium storing a program, the program being executable by a processor to perform operations comprising:

• performing flicker detection on a basis of at least one of a plurality of detection images or a plurality of restored images restored from the respective detection images, the plurality of detection images being generated for a plurality of detection regions on a basis of detection signals output from pixels in the plurality of detection regions disposed in different rows in a pixel region that is sequentially exposed row by row,
