THREE-DIMENSIONAL IMAGING DEVICE

摘要

A three-dimensional imaging device comprises an imaging unit (100) and a signal processing unit (200). The imaging unit (100) comprises a light transmission unit (2) which has first, second and third transmission areas having different pass wavelength bands from one another, a solid-state imaging element (1) which is so arranged as to receive light passing through the light transmission unit, and an optical system (3) which forms an image on an image plane of the solid-state imaging element. The signal processing unit (200) comprises an image generation unit (7) which generates three image signals respectively corresponding to the amounts of light that enters the first, second and third transmission areas on the basis of a signal output from the solid-state imaging element (1), and a disparity estimation unit (40) which estimates the disparity from the three image signals.
