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 x 24 characters (up to 288 characters)
• Number of characters displayed: Up to 288 characters
• Character format: 12 (horizontal) x 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.
