A depth estimating image capture device includes: an image sensor; an optical lens; a light-transmitting member arranged on the plane; and a signal processing section. The member includes a first mirror inside to reflect the light at least partially and a second mirror with the same reflection property as the first mirror on its upper surface. The first mirror has a reflective surface tilted with respect to the upper surface of the member. The second mirror has a reflective surface that is parallel to the upper surface. The first and second mirrors and are arranged so that a light beam coming from a point on a subject through the lens is reflected from the first mirror and from the second mirror and irradiates some area on an image capturing plane to make the irradiated area change according to the depth of the point on the subject.

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.
