描述
OV9620(彩色)和 OV9120(黑白)性能高达1.3 百万像素相机芯片,用于数字静止图像和摄像机产品。两种器件都集成了 1280x1024(SXGA) 图像阵列
和片上 10 位 A/D 转换器,能够运行在高达 15 帧/秒 (FPS),具有全分辨率。专有传感器技术采用高级算法消除固定模式噪声 (FPN),消除污迹,以及
大幅减少开花。控制寄存器允许灵活控制定时、极性和相机芯片操作,这反过来又允许工程师大量的自由产品设计。

图像处理
像素数据数字化后,进行黑电平校准可以在输出数据之前执行。黑色级别校准块减去光学的平均信号电平黑色像素以补偿像素中的暗电流输出。用户可以禁用黑色级别校准。
 
窗口
OV9620/OV9120 允许用户根据应用程序的要求定义窗口大小或感兴趣区域 (ROI)。窗口大小设置(以像素为单位)的范围为 2x4 到 1280x1024 (SXGA) 或 2x2 到 640x480 (VGA),并且可以在 1312x1036 边界内的任意位置。请注意,修改窗口大小或窗口位置不会改变帧或像素速率。窗口控制,只需更改 HREF 信号的断言,使之与编程的水平和水平 ROI 保持一致。默认窗口大小为 1280x1024。参见规格书图5 和寄存 [17], [18], [19], [1A] 和 [32] 的详细信息。
 
子采样模式
OV9620/OV9120 的默认分辨率为 1280x1024 像素,输出所有活动像素(参见图 1)。OV9620/OV9120 可编程为 640x480 输出(VGA) 大小图像,适用于分辨率更高的应用不需要图像捕获。

Description
The OV9620 (color) and OV9120 (black and white) are highperformance 1.3 mega-pixel CameraChips for digital still image and video camera products.
 
Both devices incorporate a 1280x1024(SXGA) image array and an on-chip 10-bit A/D converter capable of operating at up to 15 frames per second (FPS) with full resolution. Proprietary sensor technology utilizes advanced algorithms to cancel Fixed Pattern Noise (FPN), eliminate smearing, and drastically reduce blooming. The control registers allow for flexible control of timing, polarity, and CameraChip operation,
which in turn allow the engineer a great deal of freedom in product design.
 
Features
※  Optical Black Level Calibration
※  Video or Snapshot Operations
※  Programmable/Auto Exposure and Gain Control
※  Programmable/Auto White Balance Control
※  Horizontal & Vertical Sub-sampling (4:2 & 4:2)
※   Programmable Image Windowing
※  Variable Frame Rate Control
※  On-Chip R/G/B Channel and Luminance Average Counter
※  Internal/External Frame Synchronization
※  SCCB Slave Interface
※  Power on Reset and Power Down Mode
※  Package: CLCC48
※  CMOS SIZE: 1/2"
 
Image Processing
After the pixel data has been digitized, black level calibration can be performed before the data is output. The black level calibration block subtracts the average signal level of optical black pixels to compensate for the dark current in the pixel output. Black level calibration can be disabled by the user.
 
Windowing
OV9620/OV9120 allows the user to define window size or region of interest (ROI), as required by the application. Window size setting (in pixels) ranges from 2x4 to 1280x1024 (SXGA) or 2x2 to 640x480 (VGA), and can be anywhere inside the 1312x1036 boundary. Note that modifying window size or window position does not alter the frame or pixel rate. The windowing control merely alters the assertion of the HREF signal to be consistent with the programmed horizontal and ertical ROI. The default window size is 1280x1024. See the datasheet's Figure 5 and registers [17], [18], [19], [1A ] and [32] for detail.
 
Sub-sampling Mode
Default resolution for the OV9620/OV9120 is 1280x1024 pixels, with all active pixels being output (see Fig. 1). The OV9620/OV9120 can be programmed to output in 640x480 (VGA) sized images for applications where higher resolution image capture is not required.
