Camcorder On-Screen Display LSI
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.
Features
• 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.
