摘要： A color representation technique to be effectively applicable to a pixel shifted arrangement to realize high sensitivity and high resolution is provided by using a dipersive prism or diffraction.A dispersive element is provided for an image sensor in which photosensitive cells are arranged to be shifted from each other by a half pitch both horizontally and vertically. The dispersive element makes at least G rays fall straight down to a pixel right under itself and also makes either R rays or B rays incident on an adjacent pixel. Meanwhile, a photosensitive cell, for which no dispersive element is provided, receives directly incident light, too. Color information can be obtained by making computations on photoelectrically converted signals provided by these pixels.

摘要： The solid-state image sensor of this invention includes an array of pixels and light-transmitting portions 30a, 30b, 30c, 30d. The array is divided into unit pixel blocks, each of which is made up of N pixels (where N is an integer that is equal to or greater than two). The light-transmitting portions are arranged so that each light-transmitting portion faces an associated one of the pixels. Each of the light-transmitting portions is divided into M striped areas (where M is an integer that is equal to or greater than two). The respective areas have had their optical transmittances set independently of each other. The arrangement pattern of the optical transmittances of the light-transmitting portions 30a, 30b, 30c, 30d vary from one block to another. The image capture device of the invention further includes a shifting section for shifting the image in a first direction on an imaging area, and reads pixel signals before and after the image is shifted, thereby generating an image, of which the resolution is higher than what is defined by the pixel pitch.
