Description
This item is no longer for sale.
Features
● Small in size, low cost and low powered (3.3V) camera module for high-resolution serial bus security system or PDA accessory applications.
● On-board EEPROM provides a command-based interface to external host via RS-232.
● UART: 115.2Kbps for transferring JPEG still pictures or 160x128 preview @8bpp with 0.75fps.
● On board OmniVision VGA color sensor.
● Built-in JPEG CODEC for different resolutions.
● Built-in down sampling, clamping and windowing circuits for VGA, QVGA, 160x120 or 80x60 image resolutions.
● Built-in color conversion circuits for 2-bit gray, 4-bir gray, 8-bit gray, 12-bit RGB, 16-bit RGB or standard JPEG preview images.
● No external DRAM required.
System Configuration
1. Camera Sensor
The C328 module uses OmniVision VGA color digital CameraChips with an 8-bit YCbCr interface.
2. OV528 Serial Bridge
The OV528 Serial Bridge is a JPEG CODEC embedded controller chip that can compress and transfer image data from CameraChips to external device. The OV528 takes 8-bit YCbCr 422 progressive video data from an Sensor CameraChip. 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 can achieve higher compression ratio and better image quality for various
image resolutions.
3. Program EEPROM
A serial type program memory is built-in for C328 to provide a set of user-friendly command interfacing to external host.

描述
該產品不再銷售。
特徵
●體積小，成本低及低（3.3V），相機模塊為高清晰度串行總線的安全系統或PDA配件的應用程序。
●板載EEPROM提供了通過RS-232基於命令的接口，外部主機。
●UART：與0.75fps傳輸JPEG靜態圖片或160X128 @預覽8bpp 115.2Kbps的。
●板載VGA OmniVision公司彩色傳感器。
●內置JPEG編解碼器，不同的分辨率。
●內置下採樣，箝位和窗口電路為VGA，QVGA，160×120或80x60圖像分辨率。
●內置色彩轉換電路2位灰度，4井灰色，8位灰度，12位RGB，16位RGB或標準JPEG預覽圖像。
●無需外部DRAM。
系統配置
1.照相機傳感器
該C328模塊採用OmniVision公司的VGA彩色數碼CameraChips有一個8位的YCbCr接口。
2. OV528串口網橋
該OV528系列大橋是JPEG編解碼器嵌入式控制器芯片，可以從CameraChips到外部設備壓縮和傳送圖像數據。該OV528來自傳感器的CameraChip需要8位的YCbCr 422逐行掃描視頻數據。照相機接口與輸入的視頻數據同步，並進行下採樣，夾緊和窗口函數與所希望的分辨率，以及由用戶通過串行總線主機所請求的顏色轉換
命令。
該JPEG CODEC可以實現各種更高的壓縮比和更好的圖像質量
圖像分辨率。
3.程序EEPROM
串行式程序存儲器內置的C328提供連接外部主機一組方便用戶的命令。
