Patent number: 5502487Abstract: A character signal display for a camcorder includes a character signal generator for providing needed character data responsive to horizontal and vertical sync signals separated from a selected video signal. According to one aspect of the invention, the vertical sync signal is extracted from the selected video signal by a microcomputer while the horizontal sync signal is extracted from the selected video signal using a Hsync signal oscillator associated with an electronic viewfinder. When an external video signal is input, selection between the external video signal and the camera video signal is arbitrary; when the external video signal is not applied, the camera video signal is preferentially selected. According to another aspect of the invention, circuitry associated with the electronic viewfinder can generate both the horizontal and vertical sync signals needed by the character generator.Type: GrantFiled: August 1, 1994Date of Patent: March 26, 1996Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-gyu Choi
