Abstract: Techniques are provided for a camera control system with reduced power consumption. A system implementing the techniques according to an embodiment includes a scene change tracker configured to quantify a level of change between current and previous image frames provided by the camera. The system also includes a general purpose processor to generate camera control parameters using a first processing algorithm, based on the current and previous image frames, if the level of change exceeds a threshold. The system further includes an image signal processor to generate the camera control parameters using a second processing algorithm, based on the current and previous image frames, if the level of change is less than or equal to the threshold. The image signal processor consumes less power than the general purpose processor and the second processing algorithm is less computationally complex than the first processing algorithm.

Abstract: Technology described herein provides for adapting statistics resolution for 3A algorithms. The technology is to analyze a scene from a plurality of input images to determine a stability score, determine a target imaging statistics resolution based on the stability score, and calculate, using imaging statistics corresponding to the target imaging statistics resolution, an auto exposure parameter and/or an auto white balance parameter. In one aspect, the technology is to generate a multi-scale statistics set including a plurality of sets of imaging statistics, select the target imaging statistics resolution from a predetermined set of resolutions, and select, from the plurality of sets of imaging statistics, a set of imaging statistics corresponding to the target imaging statistics resolution. In another aspect, the technology is to compute the target imaging statistics resolution based on the stability score and a maximum imaging statistics resolution for the computing device.
