Abstract: A system is provided for the high speed reading of an image formed on the CCD sensor where the useful zones are formed of bands parallel to one of the directions of the matrix, and separated from each other by a gap without useful video information, each band and each gap being formed of several scanning lines, the geometrical arrangement of the bands on the matrix being known beforehand. The lines of each gap are transferred in succession into the register and the corresponding noise signals are not taken into account. The lines of each band are also transferred in succession so as to provided, pixel by pixel, the video signals summated in analog form for the band considered. The system applies more particularly to multichannel recording systems with streak camera.

Abstract: A device for correcting video signals in order to perform fine scanning of fast signals with a streak camera is completed by a system for correcting nonuniformity of black, nonuniformity of response of the sensing matrix and local defects of the matrix. The corresponding data are stored respectively in three memories. An image memory receives the corresponding corrected signal. Complementary means are provided for correcting nonlinearity of response of the complete chain and geometrical defects of spatial and temporal nonlinearities of the chain elements upstream of the matrix, the corresponding data being stored in two other memories.
