Abstract
A convergence device for a color camera having a correction memory for storing predetermined scanning correction signal values associated with each of the LN rectangles resulting from dividing the screen of the camera into L groups of N lines each and M columns, a sequencer for controlling the application of these correction signals to the camera scanner and an attenuator for attenuating the discontinuities existing between scanning correction signals associated with two adjacent lines of the same column.
