摘要:
A color filter is constituted by unit arrays of two columns and four rows of filter elements. The first column has cyan, magenta, cyan, and green (or green, yellow, green and cyan) filter elements which are arranged in that order and the second column has yellow, green, yellow, and magenta (or magenta, cyan, magenta and yellow filter elements which are arranged in that order. A solid state image apparatus having an expanded dynamic range is realized by using this color filter in that the dynamic range of the photoelectric elements corresponding to the green filter elements can be utilized more efficiently.
摘要:
A method for driving a solid-state image sensor in which the bias charges in a horizontal readout CCD (charge-coupled device) shift register are transferred onto vertical signal lines with the signal charges and then the signal and bias charges are transferred back into the horizontal readout CCD shift register from which are read out the signal charges (generated at the photosensor or photodiodes).

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.
