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 (640480)/BU6566GVW, SXGA size (12801024)/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. www.rohm.com 2009.04 - Rev.B 1/16 2009 ROHM Co., Ltd.

Read/ write access to internal registers (Indirect access with a index register as the address). Read/ write access to the LCD controller: Parallel/Serial (Direct access available via the LCD interface). 6) Extended overlay function Supporting overlay of icon-data/font-data of up to two points during LCD data transfer. Both icon-data and font-data corresponding to 65536 display colors. Possible to setting transparent colors. 7) LED interface, GIO function Built-in PWM output of 4 systems for 3 color LED controls and white LED control. 7 GIO s in total available for the GIO function. 8) Clock generation, power management function Oscillation circuit configuration by XIN and XOUT terminals, or clock input from XIN terminal available. Built-in PLL in BU6568GV. Clock control of IC inside in unit of block (suspend mode available). 9) Key interfaces built in 3 systems of key interfaces built in. Interruption to be generated at key input. Useable for removing software chattering. Data is prepared separately about each register setup. Please refer to the Development Scheme on page 14.
