For Home Electronics and Security Devices Camera Image Processor Series

Camera Image Processors

Compatible with JPEG Image

BU6566GVW, BU6568GV

No.09061JET02

●Description

BU6566GVW/BU6568GV is a camera image processor compatible with standard JPEG.

Pin-to-Pin compatibility enable support for both standard and high-resolution cameras.

●Features

1)Built-in Camera Module Interface

VGA size (640×480)/BU6566GVW, SXGA size (1280×1024)/BU6568GV for input of image data up to 15 fps (zooming

function is available).

Input data format for YUV=4:2:2, RGB=4:4:4.

Filter processing (image processing) to input images (2 gradations / gray scale / sepia / emboss / edge enhancement/

negative).

Multi-step size reduction down to 1/8 (BU6566GVW), 1/16 (BU6568GV) in X- and Y-direction possible.

Cutting out into an arbitrary size after resizing.

D range enlargement processing of Y (brightness) available in YUV color space to cut images.

Cut images to be stored into an arbitrary position in frame memory in YUV=4:2:2 format.

2-line serial interface built in for camera module control.

2)Built-in frame memory / JPEG code memory

Image frame memory built in (80KB for storing 1 frame of 176x232 @16 bits/pixel).

Display area settable to an arbitrary LCD size.

Data to be stored into image frame memory in YUV=4:2:2 format.

Mask data to be stored into mask frame memory in 1bit/2pixels in YUV=4:2:2 format.

An arbitrary position of frame memory to be updated to camera image according to mask memory.

Image frame memory accessible from HOST CPU (access available both in RGB and YUV).

Rectangular writing function and rectangular reading function for transparent color to image frame memory.

Frame memory usable as JPEG code memory (80KB) to store JPEG compressed images.

Frame memory usable as a ring buffer for JPEG code of 80KB or more.

3)Built-in LCD controller interface

Built-in input/output interface to LCD controller

For display colors of 262144 colors / 65536 colors / 4096 colors.

Up to 2 LCD module controllers controllable.

Arbitrary rectangular selection in frame memory to be transferred to LCD controller.

4)Built-in JPEG CODEC

ISO/IEC10918 conforming base line method.

･Compression

For YUV=4:2:2 only.

Quantization table selectable from 20 built-in tables.

･Decompression

For YUV=4:4:4, 4:2:2(horizontal sub-sampling:BU6566GVW),

4:2:0, 4:1:1(horizontal sub-sampling:BU6566GVW), and gray scale.
