d atasheet OV528 datasheet doc #ds201 ? omnivision technologies inc., 2002, version 1.0 page 5 architecture general description the OV528 serial bus camera system performs as a video camera or a jpeg compressed still camera and can be attached to a wireless or pda host. when it performs as a video camera, the tft-lcd panel of the host operates as a viewfinder. us ers can send out a snapshot command from the host in order to capture a full resolution single-frame still pi cture. the picture is then compressed by the jpeg engine and transferred to the host. functional description OV528, the single chip camera-t o-serial bridge, is a low- cost, single-chip & low-powered solution for high- resolution serial bus pda/cellular phone camera accessory applications. along with ov76x0/ov66x0 cmos vga/cif color digital camerachips, OV528 comprises a low-cost, highly integrated serial camera system. there is no additional dram required. the OV528 system, as shown in figure 1, consists of a camerachip, program memory and OV528 serial bridge. camera sensors the OV528 supports omnivision ov76x0/ and ov66x0 camerachips with an 8-bit yc b c r interface. program memory a program memory is required for the embedded mc to respond to host commands correctly, as well as to store all necessary parameters for adjusting image/compression qualities. a serial type program memory is required for OV528, while both serial and parallel types of program memory can be adapted to OV528-100. the contents of the progr am memory can be updated on the fly. OV528 serial bridge the OV528 serial bridge is a controller chip that can transfer image data from camerachips to wireless/pda hosts. the OV528 takes 8-bit yc b c r 422 progressive video data from an ov76x0/ov66x0 ca merachip. the camera interface synchronizes with input video data and performs down-sampling, clamping and windowing functions with desired resolution, as well as color conversion that is requested by the user through serial bus host commands. the jpeg codec with variable quality settings can achieve higher compression ratio & better image quality for various image resolutions. the serial camera control bus is used to achieve greater flexibility in camera interface. figure 1. system block diagram OV528 sensor ov76x0 ov66x0 (optional) program memory host eeprom free datasheet http://www.datasheetlist.com/
