Imaging device and diagnosis method

An imaging device comprising:

• a plurality of pixels each including a light-receiving element, the plurality of pixels being divided into a first pixel group and a second pixel group;
• a generating section that is able to generate a first detection value on a basis of a light-receiving result by the light-receiving element of each of the plurality of pixels belonging to the first pixel group, and is able to generate a second detection value on a basis of a light-receiving result by the light-receiving element of each of the plurality of pixels belonging to the second pixel group;
• and
• a diagnosis section, wherein
• the plurality of pixels belonging to the first pixel group and the plurality of pixels belonging to the second pixel group are associated with each other respectively to form a plurality of pixel pairs,
• the plurality of pixel pairs include a first pixel pair, and
• the diagnosis section is able to perform a diagnosis processing on a basis of a detection ratio that is a ratio between the first detection value and the second detection value in the first pixel pair.

A diagnosis method comprising:

• generating a first detection value on a basis of a light-receiving result by a first light-receiving element of each of a plurality of pixels each including the first light-receiving element and a second light-receiving element;
• generating a second detection value on a basis of a light-receiving result by the second light-receiving element of each of the plurality of pixels;
• and
• performing a diagnosis processing on a basis of a detection ratio that is a ratio between the first detection value and the second detection value in a first pixel of the plurality of pixels.

A diagnosis method comprising:

• generating a first detection value on a basis of a light-receiving result by a light-receiving element of each of a plurality of pixels belonging to a first pixel group of a plurality of pixels that each include the light-receiving element and are divided into the first pixel group and a second pixel group;
• generating a second detection value on a basis of a light-receiving result by the light-receiving element of each of a plurality of pixels belonging to the second pixel group;
• and
• performing a diagnosis processing on a basis of a detection ratio that is a ratio between the first detection value and the second detection value in a first pixel pair of a plurality of pixel pairs formed by the plurality of pixels belonging to the first pixel group and the plurality of pixels belonging to the second pixel group that are associated with each other respectively.
