SOLID STATE IMAGING DEVICE, CALCULATING DEVICE, AND CALCULATING PROGRAM

摘要

According to one embodiment, a solid state imaging device includes a first imaging device, a second imaging device, and a calculating unit. The first imaging device includes a first optical system, a first imaging unit, and a second optical system provided between the first optical system and the first imaging unit. The second imaging device includes a third optical system, a second imaging unit, and a fourth optical system provided between the third optical system and the second imaging unit. The calculating unit is configured to perform a first calculation and a second calculation. The first calculation includes deriving a first distance from stereo disparity. The second calculation includes deriving a second distance from a parallax image. The calculating unit is configured to estimate a target distance based on at least one selected from the first distance and the second distance.
