A solid state image pickup element including: an MOS image sensor comprising: photoelectric conversion elements arranged in rows and columns; vertical selection lines extending along the rows; vertical signal lines extending along the columns; a vertical switching device associated with each photoelectric conversion element and controlled by an associated vertical selection line for selectively connecting an output of the associated photoelectric conversion element to an associated vertical signal line; a horizontal switching device associated with each column for selectively connecting an associated vertical signal line to an output line; a vertical shift register for controlling the vertical switching device through the vertical selection lines; and a horizontal shift register for controlling the horizontal switching device. The photoelectric conversion elements are divided into sets of m.times.n contiguous photoelectric conversion elements, and each set is divided into groups of photoelectric conversion elements. All of the photoelectric conversion elements in each group are associated with color filters having the same color; and the vertical switching devices associated with the photoelectric conversion elements in all but one of the groups selectively connect the outputs of all of the photoelectric conversion elements in a single group to one vertical signal line associated with the single group. The photoelectric conversion elements of the one group is connected to a number of vertical signal lines.
摘要:
A color sensor array in which vertical output lines correspond to different colors. The reading order and the reading periods for each color are adjusted in one of two ways. Separate vertical shift registers are provided for each color and the separate vertical shift registers are selectively enabled. Alternatively all color are simultaneously read but the color lines are selectively coupled to one output line.

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.

A solid-state imaging device constructed according to the TSL system having a plurality of photodiodes arrayed in matrix form so as to serve as a group of pixels, a vertical selection gate line extending from a vertical scanning circuit, a horizontal selection gate line extending from a horizontal scanning circuit, and a signal read line. A projection made of an impurity layer identical to that of the photodiodes is formed at an end of each of the photodiodes. A first switching transistor is formed by interconnecting the vertical selection gate line made of a polysilicon layer so as to cross over an upper surface of each of the projections. A second switching transistor is formed by laminating a gate portion made of a polysilicon layer on the other upper surface of each of the projections. Horizontal selection gate lines are formed by connecting between the vertically arrayed gate portions and an interconnection made of a conductor layer such as an aluminum layer insulatively laminated above the polysilicon layer. Signal read lines are formed by a conductive layer fabricated by a process identical to that of the conductive layer, and each signal read line is interconnected so that the upper surface of the projection and the upper surfaces of the first and second switching transistors are shielded thereby, and that the signal read line does not come in contact with the conductive layer forming the horizontal selection gate line.
