Section 27 Video Display Controller 3
27.1
Overview
The video display controller 3 provides the following four functions. Note that the video display
function and video recording function cannot be used together.
function and video recording function cannot be used together.
1. Video display function: Reduces the size of the input video, buffers the resultant video data in
the memory, and then displays the video on the panel.
2. Video recording function: Stores a specified number of input video fields in on-chip large-
capacity RAM or SDRAM.
3. Function for overlaying graphics images (two planes) on the input video.
4. Function for outputting the control signals for the TFT-LCD panel.
