    Abstract: In one embodiment, an image sensor includes, a bank 301 of charge-coupled devices, and charge sensing amplifiers 302, each of which transforms electric charges extracted from an associated pixel into an electrical signal. After the electric charges accumulated in every pixel have been extracted to the charge-coupled devices 301 at the same time, a color component with a high resolution is output to a horizontal transfer path 316 via the charge sensing amplifiers 302 and then output to a device outside of the image sensor. Thereafter, pixel signals representing another low-resolution color component are vertically added together on the bank 301 of charge-coupled devices. Those pixel signals are horizontally added together on the horizontal transfer path 316 and output. The image obtained by this image sensor is then input to an image processing section, thereby obtaining an output color image with a high resolution and a high frame rate.

    Abstract: An image processing device includes: a coordinate conversion unit (142) which calculates a corresponding sampling coordinate on a color mosaic image corresponding to a pixel position of a color image when a deformation process is performed, according to the pixel position of the color image; a sampling unit (143); a sampling unit (143) which interpolates-generates a pixel value in a sampling coordinate for each of color planes obtained by decomposing the color mosaic image; and a color generation unit (144) which generates a color image by synthesizing interpolation values of the respective color planes. Each pixel value of a color image subjected to a deformation process is obtained as a pixel value of the sampling coordinate from the color mosaic image by interpolation calculation, thereby realizing the color interpolation process for generating a color image from the color mosaic image and a deformation process of the color image by one interpolation calculation.
