BU6569GVW Datasheet | ROHM

Description BU6569GVW is a camera image processor with ADPCM/MIDI/MP3/AAC/HE-AAC Audio. - Features 1) Built-in Camera Module Interface UXGA size (16001200) for input of image data up to 7.5 fps, SXGA size (12801024) for input of image data up to 15fps and VGA size (640480) for input of image data up to 30fps (zooming function available). Input data format for YUV=4:2:2, RGB=4:4:4 (8 bits for each RGB). Filter processing (image processing) to input images (2 gradations / gray scale / sepia / emboss / edge enhancement / negative). Multi-step size reduction down to 1/16 in X- and Y-direction possible, cutting out into an arbitrary size after resizing. Cut images to be stored into an arbitrary position in frame memory in YUV=4:2:2 format or RGB=5:6:5 format (16bit/pixel). 2) Built-in frame memory / JPEG code memory Built in image frame memory (160KB to store 1 frame of 320240@16bit/pixel). Data to be stored into image frame memory in YUV=4:2:2 format or RGB5:6:5 format (16bit/pixel). An arbitrary position of frame memory to be updated to camera image according to mask frame memory. Mask data to be stored into mask frame memory in 1bit/2pixels in YUV=4:2:2 format or 1bit/1pixels in RGB=5:6:5 format. Rectangular writing function and rectangular reading function as transparent color to image frame memory. Frame memory is usable as JPEG code memory (192KB) to store JPEG pressed images. Frame memory is usable as a ring buffer for JPEG code of 192KB or more. 3) Built-in LCD controller interface Built-in input/output interface which type is CPU I/F, to LCD controller For display colors of 262144 colors / 65536 colors / 4096 colors. Up to 2 LCD module controllers, MAIN and SUB, controllable. Arbitrary rectangular selection in frame memory to be transferred to LCD controller. Multi-step scaling process in the range of 1/4 to 2 in X- and Y-direction is available to display images from frame memory to the LCD. 4) Extended overlay function Supporting overlay of icon-data up...
