Abstract: An eyewear device having an image processor operable in a camera pipeline for computer vision (CV) and in augmented reality (AR) systems. The image processor is configured to selectively control a plurality of cameras to provide images having a first resolution in the high power AR mode, and to provide the images having a second resolution in the low power CV mode. The first resolution is higher than the second resolution, and the plurality of cameras consume less power in the CV mode than the AR mode. The image processor controls the camera pipeline to process the first resolution high IQ images from the plurality of cameras to operate in the AR mode, and controls the camera pipeline to process the second resolution lower IQ images from the plurality of cameras to operate in the CV mode. Substantial power is saved by reducing the resolution of the images using downscaling in the cameras themselves in the CV mode.
