LC74772V
CMOS LSI
On-Screen Display LSI
for Camcorder
http://onsemi.com
Overview
The LC74772V is a CMOS LSI that implements on-screen display for camcorders. It displays characters and
patterns in a camcorder viewfinder under microprocessor control. The LC74772V displays a 12 18 dot font with
256 characters.
Functions
Screen format: 12 lines 24 characters (up to 288 characters)
Number of characters displayed: Up to 288 characters
Character format: 12 (horizontal) 18 (vertical) dots
Number of characters in font: 256 characters
Character sizes: Normal and double, specified in line units
Display start position
— Horizontal: 64 positions
— Vertical: 64 positions
Character reverse video function: Individual characters can be displayed in reverse video.
Types of blinking: Two types with periods of 1.0 and 0.5 seconds, specifiable on a per character basis.
(Blinking has a 60% display on duty.)
(Four divisors: 1/25, 1/30, 1/50, 1/60)
Outputs: R, G, B plus 2 output systems
Or: 4 output systems (character data and blanking data: 4 outputs each)
External control input: 8-bit serial data input format.
