Abstract: Arranged downstreams of a camera (1) for the serial or parallel-serial analysis of a field of view, the device comprises a digitizing device A/D (2) which serially supplies samples which are coded in parallel over p bits, a digital-to-analog converter D/A (3) and a monitor TV (4). According to the invention, the device furthermore includes, arranged between the A/D (2) and the D/A (3) a line memory (11) comprising an integral number N of lines, which serves as a buffer memory between the lines entering at the variable rate of the optomechanical analysis lines and the lines outputted at the fixed rate of the TV lines. The number N is chosen to be substantially equal to the instantaneous maximum possible shift of the number of lines between the analysis and their recovery. A picture clock pulse generator supplies the synchronizing signals, of the TV standard, necesssary for the analyser of the camera and for the line memory. Use: picture sensors with optomechanical analysis.
