CMOS OV7725 Camera 0.3MP
CMOS OV7725 Camera Module 1/4-Inch 0.3-Megapixel Module
The OV7725 camera module is based on Omnivision OV7725 image sensor which is a low voltage CMOS device that provides the full functionality of a single-chip VGA camera and image processor, as well as the extraordinary high frame rate and low light performance. The OV7725 provides full-frame, sub-sampled or windowed 8-bit/10-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. This device has an image array capable of operating at up to 60 frames per second (fps) in VGA with complete user control over image quality, formatting and output data transfer. All required image processing functions, including exposure control, gamma, white balance, color saturation, hue control and more, are also programmable through the SCCB interface. In addition, OmniVision sensors use proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise, smearing, blooming, etc., to produce a clean, fully stable color image
OV7725 相機模組基於 Omnivision OV7725 影像感測器，該感測器是一款低壓 CMOS 裝置，可提供單晶片 VGA 相機和影像處理器的全部功能，以及非凡的高幀速率和低光性能。
OV7725 提供多種格式的全幀、子採樣或視窗 8 位元/10 位元影像，並透過序列相機控制匯流排 (SCCB) 介面進行控制。
該裝置的影像陣列能夠在 VGA 中以高達每秒 60 幀 (fps) 的速度運行，使用者可以完全控制影像品質、格式和輸出資料傳輸。
所有必要的影像處理功能，包括曝光控制、伽瑪、白平衡、色彩飽和度、色調控制等，都可以透過 SCCB 介面進行程式設計。
此外，OmniVision 感測器使用專有感測器技術，透過減少或消除影像污染的常見照明/電源（例如固定圖案雜訊、拖尾、暈染等）來提高影像質量，從而產生乾淨、完全穩定的彩色影像
