Abstract
A picture editing apparatus for use in a video camera that generates a video signal for a picture with successive video lines is capable of providing a window and a blank area within the picture. The apparatus comprises a selection button for generating a signal to select a vertical length and a horizontal width of the window; a synchronization signal generator for generating synchronization signals; a control unit, in response to the selection signal, for processing the synchronization signals to generate a window signal; a window generator, in response to the window signal, for processing the video signal to derive the window and the blank area.
Claims5
An apparatus for editing a picture by providing a window and a blank area within the picture for use in a video camera, generates a video signal for the picture with successive video lines, wherein the time taken to generate each video line is divided into a plurality of time intervals, said apparatus comprises:
- means for generating a selection signal to select a vertical length and a horizontal width of the window;
- means for generating vertical synchronization signals and horizontal synchronization signals for each video line;
- control means, in response to the selection signal, for controlling the synchronization signals to generate a window signal;
- and
- a window generator, in response to the window signal, for processing the video signal to derive the window.
