摘要： This solid-state image sensor includes an array of photosensitive cells and an array of dispersing elements. The photosensitive cell array is comprised of multiple unit blocks, each of which includes four photosensitive cells arranged two dimensionally. The dispersing element array is arranged so as to face the photosensitive cell array and includes a plurality of dispersing elements. The dispersing element array directs light respectively onto the four photosensitive cells by selectively subtracting certain complementary color components from the incoming white light, and adding a light ray with a selected complementary color component to the remainder. The dispersing element array is configured such that the combination of color component that is subtracted from the incoming light and the color component in the added light ray is selected for the incident light on each of the four photosensitive cells.

摘要： The 3D image capture device includes a light-transmitting section with n transmitting areas (where n is an integer and n≧2) that have different transmission wavelength ranges and each of which transmits a light ray falling within a first wavelength range, a solid-state image sensor that includes a photosensitive cell array having a number of unit blocks, and a signal processing section that processes the output signal of the image sensor. Each unit block includes n photosensitive cells including a first photosensitive cell that outputs a signal representing the quantity of the light ray falling within the first wavelength range. The signal processing section generates at least two image data with parallax by using a signal obtained by multiplying a signal supplied from the first photosensitive cell by a first coefficient, which is real number that is equal to or greater than zero but less than one.

摘要： An imaging photodetection device (4) includes: a plurality of photodetectors (6) that are arrayed on a substrate (5) at least along a first direction; a transparent low refractive index layer (12) that is formed above the plurality of photodetectors; and a plurality of transparent high refractive index sections (13) that are embedded in the transparent low refractive index layer along the first direction. On a cross-section of the transparent high refractive index sections orthogonal to the substrate and along the first direction, central axes (14) of the transparent high refractive index sections are bent stepwise. Light that enters the transparent low refractive index layer and the transparent high refractive index section passes therethrough to be separated into 0th-order diffracted light, 1st-order diffracted light, and −1st-order diffracted light. Thereby, improvement in the efficiency of light utilization and pixel densification can be realized.

摘要： A solid-state image sensor according to the present invention includes a number of photosensitive cells 2b, 2c that are arranged in between the first surface 30a of a semiconductor layer 30 and its second surface 30b, which is opposite to the first surface 30a and which receives incoming light. As viewed from the photosensitive cells 2b, 2c, a reflecting portion 3a is arranged on the same side as the first surface 30a in order to reflect an infrared ray that has been transmitted through the photosensitive cell 2c and make it incident on one of the photosensitive cells 2b, 2c. As a result, the intensities of infrared rays to be converted photoelectrically by the photosensitive cells 2b, 2c will be different from each other. And by calculating the difference between the photoelectrically converted signals supplied from the photosensitive cells 2b, 2c, the infrared ray component received by each photosensitive cell can be obtained. In addition, by arranging a color filter 1b on the same side as the second surface 30b, an infrared ray component and a color component can be obtained at the same time.

摘要： In one embodiment, an element 106 transform, with a voltage, non-polarized light into plane polarized light with an arbitrary plane of polarization. A synchronizer 112 gives the plane of polarization control element 106 an instruction to rotate the plane of polarization, thereby getting the plane of polarization of the illumination rotated and casting that polarized light toward the object. At the same time, the synchronizer 112 sends a shooting start signal to an image sensor 110, thereby getting video. The synchronizer 112 performs these processing steps multiple times. A captured video signal is sent to an image processing processor 108, where LL, RR and CC images are separately generated as images of light rays that have passed through left and right polarizing areas and the central non-polarizing area and left and right parallax signals are generated and sent to a 3D display section 122.
