Abstract:
1. A method comprising: detecting a full resolution image at an image sensor; adaptively selecting, at the image sensor, at least one first full resolution region within the detected full resolution image for adaptively scaling with a first scaling rate; adaptively selecting, at the image sensor, at least one second full resolution region, different from the at least one first full resolution region, within the detected full resolution image for adaptively scaling with a second scaling rate, different from the first scaling rate; adaptively scaling, at the image sensor, the selected at least one first full resolution region within the detected full resolution image using the first scaling rate to provide a first scaled region; adaptively scaling, at the image sensor, the selected at least one second full resolution region within the detected full resolution image using the second scaling rate to provide a second scaled region; and providing the first scaled region and the second scaled region for further processing, wherein the further processing comprises calculating autofocus information using at least the first scaled region wherein the autofocus information is configured to control automatically a focusing quality of the first region by positioning at least one lens.
