    摘要: This disclosure describes techniques for improving functionalities of a back-end device, e.g., a video encoder, using parameters detected by a front-end device, e.g., a video camera. The techniques may involve detecting a scene change in a captured frame, based on one or more parameters of auto exposure (AE), auto white balance (AWB), and auto focus (AF) functions. If a scene change is detected in a captured frame, a video processing device, which may be a stand-alone device, or may be integrated into one of the front-end or back-end devices, provides an indication of the scene change. The video encoder interprets the signal as a trigger to encode the frame indicated as the frame where a scene change occurred as a reference I frame.

    摘要: An example image capture device determines a region of interest using a first image captured while a light source is powered off and a second image captured while a light source is powered on and uses the region of interest to automatically set configurations. In one example, an image capture device includes a controlled light source, an image sensor configured to capture images, and a processing unit configured to cause the image sensor to capture a first image of a scene while the controlled light source is powered off, cause the image sensor to capture a second image of the scene while the controlled light source is powered on, calculate luminance differences between a plurality of regions in the first image and a plurality of collocated regions in the second image, and determine that a region of interest includes those regions for which the luminance differences exceed a threshold.
