Solid-state imaging element, imaging device, and signal processing method including a dispersing element array and microlens array
This solid-state image sensor includes a photosensitive cell array including first through fourth photosensitive cells 2a to 2d, a dispersing element array including first and second dispersing elements 1a and 1b arranged to face the first and third photosensitive cells 2a and 2c, respectively, and a microlens array including first and second microlenses 4a and 4b. The first dispersing element 1a makes parts of incoming light that have come through the first microlens 4a and that have first and second color components incident on the first and second photosensitive cells 2a and 2b, respectively. The second dispersing element 1b makes parts of incoming light that have come through the second microlens 4b and that have third and fourth color components incident on the third and fourth photosensitive cells 2c and 2d, respectively. In addition, light that has not passed through the first and second microlenses 4a and 4b is also incident on the second and fourth photosensitive cells 2b and 2d.
