TI OV10640汽车1．3M照相模块TIDA－00421参考设计时间：2016-04-07 10:21:51作者：TI来源：中电网TI公司的汽车1.3M照相模块TIDA-00421参考设计采用图像传感器OV10640和FPD-Link III串行化器DS90UB913A以及降压转换器TPS62170-Q1.支持1280x1080,VGA,QVGA和任何的缩放尺寸,具有高动态范围,高灵敏度和安全特性以及低功耗等特性.主要用在ADAS可视系统,环视系统和后视摄影镜头.本文介绍了OV10640主要特性,框图,以及汽车1.3M照相模块TIDA-00421参考设计主要特性,框图,电路图,材料清单和PCB设计图.The OV10640 is the automotive industry’s first image sensor to utilize backside illumination technology, enabling industry-leading sensitivity and high dynamic range (HDR) up to 120 dB in the smallest possible automotive-grade package. The OV10640 is well suited for a broad range of advanced driver assistance systems (ADAS), including: 360-degree surround view, rear view, machine vision, blind spot detection, and lane departure warning.?The sensor’s 4.2-micron OmniBSI? pixel is capable of recording highly detailed full-resolution 1.3-megapixel images and video at 60 frames per second (fps). The sensor uses OmniVision’s unique split pixel HDR technology, in which the scene information is sampled simultaneously rather than sequentially, minimizing motion artifacts and delivering superior image quality in RAW output in the most demanding and difficult lighting conditions.?The OV10640 contains a well-defined feature set to fulfill Automotive Safety Integrity Level (ASIL) according to ISO26262. The sensor fits into a compact chip-scale package (CSP), and is expected to complete AEC-Q100 Grade-2 qualificationsOV10640主要特性:support for image size: 1280x1080,VGA, QVGA and any cropped sizehigh dynamic rangehigh sensitivitysafety featureslow power consumptionimage sensor processor functions:- automatic exposure/gain control- lens correction- defective pixel cancelation- HDR combination and tone mapping- automatic black level correctionsupported output formats: RAWhorizontal and vertical sub-samplingserial camera control bus (SCCB)for register programminghigh speed serial data transferwith MIPI CSI-2external frame synchronizationcapabilityparallel 12-bit DVP outputembedded tempe
