Abstract: An apparatus for photographing a moving body. A video memory including a plurality of frame memories is used in order to store frame images obtained by a plurality of photographing operations. The frame images obtained by photographing are sequentially stored in any of frame memories. Any of a plurality of frame memories is selected in accordance with a detection of a front edge or a rear edge of a vehicle, and a frame image in a selected frame memory is used. A speed of a vehicle is used for this selection. In another case, apparatuses for photographing, such as TV cameras or storage devices such as video memories are provided in a plurality of systems, and a frame relating to either of the systems is selected in accordance with the speed. The high speed processing is enabled without image processings such as clipping of characters on a license plate.

Abstract: An automatic debiting system and method suitable for free lane traveling. Debiting antennas disposed on a first gantry are used to communicate with an in-vehicle unit (IU) mounted on the vehicle for debiting. The passages of the vehicles are detected by the loop coils or line scanners, and the license plates, etc., of the vehicles are photographed by the enforcement cameras. Debiting confirmation antennas on second gantry are used to communicate with the IU for the confirmation of debiting. When the normal debiting is confirmed, a local controller informs a system central controller of the fact, whereas when abnormal debiting is confirmed, images of the license plate, etc., of the illegal vehicle are transmitted to the system central controller as illegal vehicle images. The debiting is thus possible at the time of free lane traveling.

Abstract: A method for driving a solid-state image sensor in which the bias charges in a horizontal readout CCD (charge-coupled device) shift register are transferred onto vertical signal lines with the signal charges and then the signal and bias charges are transferred back into the horizontal readout CCD shift register from which are read out the signal charges (generated at the photosensor or photodiodes).

Abstract: Solid state color imaging apparatus comprises a solid state photoelectric device such as an interline type CCD having a color filter in front of it. The color filter has a number of minute filter elements disposed forming vertical column and at the same time horizontal rows,each vertical column comprising repetition of transparent element, cyanic element, transparent and yellow elementeach odd number horizontal rows, comprising repetition of transparent element and yellow element,each even number horizontal rows comprising repetition of transparent element and cyanic element, andin two-dimensional disposition the transparent elements are disposed in chequered pattern.
