1. Overview

Video display controller 5

 Four graphics layers (two of them also for input video)

Available input pixel formats

1 bit/pixel: CLUT1

4 bits/pixel: CLUT4

8 bits/pixel: CLUT8

16 bits/pixel: YCbCr422 (graphics layers 0 and 1), RGB565, ARGB1555, RGBA5551, ARGB4444

32 bits/pixel: ARGB8888, RGBA8888, RGB888, YCbCr444 (graphics layers 0 and 1)

 Blending of two input video images

Two input video images superimposed by alpha blending over a rectangular area can be output.

 Superimposition

Alpha blending in a rectangular area:

Input video, layer 1, and layer 2 blended according to the transparency percentage α

(fade-in and fade-out function available)

Chroma key function:

Mixing based on transparency percentage α using the specified RGB and CLUT value

Pixel-base alpha blending:

Alpha blending for each pixel based on transparency percentage α

Generation of output video images

Video images superimposed on graphics layers can be output to memory.

 Panel output control

Panel output correction:

Brightness adjustment and contrast adjustment, gamma correction, panel dithering

TCON:

Various timing output for LCD panel driving provided by a total of seven vertical and horizontal

panel driver signals

Panel output pixel format: RGB888, RGB666, RGB565, serial RGB

Output video image size:

Maximum output video image size to be set*:

1999 pixels × 2035 lines (horizontal × vertical)

Note:*Depends on the AC characteristics of the display panel.

Examples of output video image size:

WXGA (1280 × 768)

XGA (1024 × 768)

SVGA (800 × 600),

WVGA (800 × 480),

VGA (640 × 480),

WQVGA (480 × 240),

QVGA (320 × 240, 240 × 320)

Dynamic range compression

 Two channels

 Contrast adjustment of captured data

Contrast expansion processing optimized per region of the image

Image renderer

(IMR-LS2)

 Two channels

 Refers to the video captured data as two-dimensional texture data and draws a shape by performing

texture mapping for an arbitrary shape divided into triangular objects.

 Display list system

 Drawing functions

Texture mapping, bilinear filtering, automatic coordinate generation (and relative coordinate input)

 Instruction system

Draw instruction: TRI for drawing a triangle

Control instructions: TRAP, INT, NOP, SYNCM, SYNCW, WTL, and WTS

 Drawing space

Destination coordinates: 0 ≤ X ≤ 2,047, 0 ≤ Y ≤ 2,047

Source coordinates: 0 ≤ u ≤ 1,439, 0 ≤ v ≤ 1,023

Image renderer for display

(IMR-LSD)

 Refers to the output video image data from the video display controller 5 (channel 0) as two-

dimensional texture data and draws shapes by performing texture mapping for an arbitrary shape

divided into triangular objects.

 Display list system

 Drawing functions

Texture mapping, bilinear filtering, automatic coordinate generation (and relative coordinate input)

 Instruction system

Draw instruction: TRI for drawing a triangle

Control instructions: TRAP, INT, NOP, SYNCM, SYNCW, WTL, and WTS

 Drawing space

Destination coordinates: 0 ≤ X ≤ 2,047, 0 ≤ Y ≤ 2,047

Source coordinates: 0 ≤ u ≤ 1,439, 0 ≤ v ≤ 1,023
