1. GENERAL DESCRIPTIONS
VC0528BRVC is the cost down version from the VC0568 solution. It supports the sensor
up to 0.3Mega, and uses SRAM technology. It is the most cost efficient mobile camera
processor in the market place.
By integrating JPEG codec, sensor interface, LCD controller interface, VC0528BRVC
enables mobile phone designers to quickly add camera solutions to their products with
performance approaching leading digital still cameras.
VC0528BRVC can capture still images (up to 0.3 Mega resolutions) and video clips, and
pass them to mobile phone baseband device, or receive JPEG images, MJPEG video
from baseband device for LCD display.
VC0528BRVC can support hardwired image scaler, that supports zoom in and zoom out
from 1/16 to 2x, VC0528BRVC also provides special image effects.
The following package is available:

4. KEY BLOCK DESCRIPTIONS
VC0528BRVC-1102-V1.05-EN
4.1. Overview
The main internal blocks in VC0528 are:
Sensor Interface (SIF)
Image data in YUV422 format is captured synchronously. The sensor clock is generated by
VC0528 and it can be adjusted accordingly up to 48MHz, while the pixel rate can reach
48MHz. VC0528 supports up to 1280x1024 image resolution from the sensor. Serial bus
interface is used for controlling the sensor.
Image Post Processing (IPP)
This module can add special effects to the image during capture and display, such as sepia,
color range, negative, etc. Also, when the resolution of the input image from the sensor or
host CPU does not match display or capture requirement, IPP can be used to convert these
images into appropriate size, i.e., screen display size or the capture resolution set by users.
LCD Display Controller (LCDC)
This module generates the correct data for LCD panel to display. Alpha blending and overlay
function between video and graphics from host CPU are supported. Rotation (90, 180 and 270
degree), mirror (horizontal and vertical) and gamma correction on video plane are all
supported in this module.
LCD Panel Interface (LCDIF)
VC0528 supports TFT and STN-type LCD panels up to QVGA resolution (320x240). It
communicates with the LCD panel through standard asynchronous 8/16 bit data bus with the
color depth of 4/8/12/16/18 bit per pixel. Direct interface between host CPU and LCD panel is
also supported.
JPEG Codec (JPEG)
VC0528 has an embedded JPEG codec for both image compression and decompression. The
input of the encoder comes from either the sensor or the host CPU under different operation
modes, and the output of the encoder is saved in on-chip SRAM for host CPU to read. The
input of the decoder is from the on-chip SRAM which can be accessed by the host CPU and
the decompressed data is sent back either to host CPU or LCD display. The JPEG CODEC
supports YUV422, YUV411, YUV420, YUV400 data format.
