A linear image sensor chip is manufactured by forming an image pickup section, peripheral circuit sections, a plurality of bonding pads, and a light-suppressing layer on a semiconductor substrate having an elongated shape. In this case, each of the bonding pads is formed outer than photodiode groups in the image pickup section along a longitudinal direction of the semiconductor substrate. Even if the dynamic range of an image reader utilizing such a linear image sensor chip is broadened, it is possible to suppress generation of noises without lowering the sensitivity.

A stereoscopic camera includes a master camera for photoelectric conversion of object light to generate a first image signal with three color components G, R and B. A slave camera generates a second image signal. In an adjusting method, a first gain Dmr, Dmg and Dmb of the color components is determined according to the first image signal to correct a brightness level and white balance of the master camera, to adjust the first image signal by use thereof. A second gain Dsr, Dsg and Dsb of the color components is determined according to the first gain and color calibration information predetermined according to color sensitivity of the master and slave cameras in relation to the color components. The second image signal is adjusted by use thereof, for color matching between the first and second image signals to set equal the brightness level and the white balance.

An apparatus for image taking includes a range image sensor, in which a range image is produced in which a distance is represented with a pixel value by image taking of a principal object from an image taking position. An image pickup device receives light reflected by the principal object, to output an image signal for respective pixels. A light reception control unit changes over a reception sequence and reception time, and causes the image pickup device to output image signals associated with first and second distance ranges. The second distance range is a distance range where the principal object exists and is over the first distance range. A first range image and second range image, are formed according to the image signals. Blank portions are designated within the second range image by comparison of the first range image and second range image, to compensate for the blank portions.

A liquid crystal display unit has a transmissive liquid crystal plate having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal plate from back. An interface circuit receives an image signal representative of a color image to sequentially form on said liquid crystal plate a plurality of separation images in which the color image is separated in association with the plurality of luminescent colors of said light source unit. The interface circuit causes said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal plate in synchronism with a sequential formation of the separation images onto said liquid crystal plate. Beams of light emanated from the light source unit and transmitted through the liquid crystal plate reproduce an image.
