Abstract: Disclosed is a method of restoring specific scene whose objectives are to provide a specific scene restoration system having a sufficient detection rate enough to easily detect and pick up the specific scene from a plenty number of video data, or to detect in real time such scene as those whereon specific motions exist, comprising the steps of dissecting into k×k=N blocks( where N is 100 or less, desirably an integer in the range of 9 to 36) each frame of a motion video signal wherein a series of specific scenes to be restored are contained, calculating the motion quantities in each block using the total sum of the motion vector magnitudes in each block, obtaining a Mahalanobis distance D2 for the images of said specific scenes, calculating a threshold defined by the average of D2 plus standard deviation of D2, comparing the threshold to the Mahalanobis distance D2 calculated for each frame of the motion video signal to be retrieved, and by detecting the specific scene to be obtained on condition that the Mah

Abstract: An image forming apparatus for forming an image corresponding to a subject is provided, which image forming apparatus includes a taking lens for making an optical image corresponding to the subject, and a dividing portion for dividing the optical image transmitted via said taking lens into several adjacent optical image parts. The image forming apparatus further includes several solid-state image sensors corresponding to the number of the optical image parts, each of said solid-state image sensors receiving a corresponding optical image part from among the several optical image parts from the dividing portion and outputting an image signal corresponding to the optical image part, the optical image parts received by said solid-state image sensors being adjacent to each other.

Abstract: A plurality of photoconductive cells are each formed on an insulating substrate to extend in a straight line. The photoconductive cells are divided into m groups, each consisting of n cells, which is connected at one end to a common electrode, and corresponding ones of the photoconductive cells of the m groups are connected to individual select electrodes, respectively. By turning ON group select switches in a sequential order, the common electrodes are connected to a power source one at a time and, by sequentially turning ON individual select switches, the individual select electrodes are connected to a load one at a time. The common electrodes are grounded via grounding switches which operate reversely from select switches connected to the common electrodes. The individual select electrodes are grounded via grounding switches which operate reversely from select switches connected to the individual select electrodes.

Abstract: A photo-electric converting apparatus comprises an array wherein a plurality of photo-electric converting elements are provided, each of which having a semiconductor film layer arranged between an electrode layer and another electrode layer formed on a substrate, and having at least either a rectifying contact or a P-N junction. When the array is irradiated with light under such condition that substantially no bias voltage is applied between the electrode layers of the array, each of the photo-electric converting elements produces forward e.m.f., and forward current flows. A capacitive means in each of the photo-electric converting elements is charged with the forward current, and the capacitive means are discharged successively by scanning pulses, and timed pulse signals are outputted. The present invention discloses further various concrete constructions of the photo-electric converting element and the array thereof with high efficiency of conversion.
