THREE-DIMENSIONAL IMAGING DEVICE AND OPTICAL TRANSMISSION PLATE

摘要

A 3D image capture device includes: a light-transmitting section 2 with N fan-shaped light-transmitting areas (where N is an integer and N≧3) with different transmission wavelength ranges; a solid-state image sensor 1 that receives the light transmitted through the light-transmitting section 2; an optical system 2 that produces an image on an imaging area of the sensor 1; and a signal processing section 200 that processes the output signal of the sensor 1. The sensor 1 includes a photosensitive cell array and a color filter array that are made up of unit elements, each of which includes N photosensitive cells and N color filters. The transmission wavelength ranges of the light-transmitting areas and the color filters are defined so that the light transmitted through at least one of the N light-transmitting areas is transmissible through at least two of the N color filters. The signal processing section generates signals representing at least two of the respective intensities of light rays incident on the light-transmitting areas based on the output signals of the photosensitive cells, thereby generating data representing at least two images with parallax.
