Abstract: A matrix comprising blocks, each made up of a set of thin-film unit elements of semiconductor, either light-sensitive or controlling a light valve, is driven by applying voltage pulses (T1, T2 etc) to the blocks in turn, and while each block is enabled, selected elements in that block are read or energized. To reduce dark current, a short pulse P is applied to all of the blocks in the gaps between the enabling pulses. The number of pulses P applied to each block before enablement may be finite, eg 5 to 10, and yet provide adequate reduction in dark current.

Abstract: A recording apparatus for recording images and auxiliary information on a long footage of film is provided with input means for inputting the number of images recordable on a predetermined length of strip film held by the holding portions of a film jacket having a plurality of holding portions for holding strip films and the number of the holding portions of the film jacket, first counter means for counting the images recorded on the long footage of film, second counter means for counting signals generated when the first counter means has counted the images recorded on the long footage of film by the number of images input to the input means, third counter means for counting signals generated when the second counter means has counted said signals by the number of holding portions input to the input means, and means for recording on the long footage of film information corresponding to the count value of the third counter means. The auxiliary information recorded on the long footage of film enables one to know the locations whereat the long footage of film is to be cut and strip films cut from the long footage of film can be properly held by a predetermined film jacket, whereby the possibility of mistaking the held position of the strip films is eliminated.
