An image sensor comprising a plurality of pixels in which at least two or more pixels have a charge control structure used to change charge capacity during the integration time; wherein at substantially a beginning of an exposure time the charge capacity is altered to substantially zero by ...
Image of an HDR scene with local tone mapping Dynamic Range (DR) is the range of exposure, i.e., scene brightness, over which a camera responds with good contrast and good Signal-to-Noise Ratio (SNR). This is a scene-dependent image quality factor that incorporates sensor sensitivity, noi...
因为暗部信息为0,所以我们认为背光强度不足,当我们试着增大背光亮度,远超sensor感光极限,但是还是发现总有多阶暗部信息一直为0。 至此,我们判断该问题应该为相机对弱光信号处理出现问题,或者是Sensor感光性能出问题、或者是暗部过度降噪、或者是BLC不正确等原因。这种情况下,负责相机驱动和ISP的图像工程师,应及时对相机...
