LC74772V

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.
