        The OV7725 Camera\u2122 image sensor is a low-voltage CMOS device that provides the full functionality of a single-chip VGA camera and image processor in a small package. The OV7725 is controlled via a serial camera control bus (SCCB) interface and provides full-frame, subsampled or windowed 8-bit\/10-bit images in multiple formats. The device has an image array that runs at 60 frames per second (fps) in VGA, with full user control over image quality, format and output data transmission. All necessary image processing functions, including exposure control, gamma, white balance, color saturation, hue control, etc. Features: High sensitivity for low light operation Standard SCCB interface Output support for raw RGB, RGB (GRB 4:2:2, RGB565\/555\/444) and YCbCr (4:2:2) formats Support image sizes: VGA, QVGA and any size from CIF down to 40\u00d730 Automatic image control functions, including: automatic exposure control (AEC), automatic gain control (AGC), automatic white balance (AWB), automatic bandpass filter (ABF) and automatic black level calibration (ABLC) Image quality control, including color saturation, hue, gamma, sharpness (edge enhancement) and anti-signal interference ISP includes noise reduction and defect correction Lens shading correction Automatic adjustment of saturation level (UV adjustment) Automatic adjustment of edge enhancement level Automatic adjustment of noise reduction level Frame synchronization capability Dogoozx OV7725 camera module recommendation: Dogoozx Free Drive OV7725 480p Wide Angle 120 degree USB Camera Module Dogoozx High-end OV7725 0.3MP VGA 60fps ISP Low Light DVP Face Recognition Camera Module Dogoozx OV7725 with ISP YUV VGA Long focal narrow angle photo recognition Camera Module Dogoozx VAG with ISP YUV 60fps Scan Code visitor access control OV7725 DVP camera module Dogoozx VGA 0.3MP 480P 60fps ov7725 1\/4 cmos fixed focus scan code DVP camera module<\/p>","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","footnotes":""},"categories":[622],"tags":[],"class_list":["post-13069","post","type-post","status-publish","format-standard","hentry","category-0-3mp-480p-camera-sensor"],"_links":{"self":[{"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/posts\/13069","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/comments?post=13069"}],"version-history":[{"count":0,"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/posts\/13069\/revisions"}],"wp:attachment":[{"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/media?parent=13069"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/categories?post=13069"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/dgzx.hk\/pa\/wp-json\/wp\/v2\/tags?post=13069"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
