摘要

The device for dynamic correction of defects in geometry and in convergence of the objective 10 of a camera includes systems 1, 3 for copying optical parameters for adjusting focal length and focusing, which are used after analogue/digital conversion 2, 4 in order to address a PROM memory circuit 5 in which have been stored error correction values resulting from a preliminary calibrating of the objective as a function of variations in the optical parameters. These correction values are used to modulate the camera's base signals, for example line and frame sawtooth signals, the resulting signals being superimposed on the line and frame scanning signals which may already be corrected for other defects. Application to cameras in which very high quality is required. IMAGE
