Title: Video camera with a semiconductor sensor
Inventor: GRIMM MICHAEL DIPL ING
IPC: H04N1/04
Filed: 1993-03-12
Abstract: In a video camera, it is known, for increasing the resolution in accordance with the so-called microscanning principle, to shift the relative position between the projected image and the sensor horizontally and/or vertically by fractions of pixels or line spacings. During this process, a motional unsharpness can occur in the horizontal or vertical direction. It is the object to reduce or to eliminate such a motional unsharpness. The sensor is in each case sampled several times during a standardised vertical period and the video signal obtained by this process is converted into a video signal having the standardised vertical period by processors (5, 6) containing frame buffers. Especially for cameras with increased resolution and for rapid motional processes. <IMAGE>
