1. An image processing system, comprising: circuitry configured to: determine whether a focus operation is performed on image data, process the image data in a high resolution mode when the focus operation is determined to be performed on the image data, process the image data in a low resolution mode when the focus operation is determined not to be performed on the image data, and switch between the low resolution mode and the high resolution mode based on whether edges of an in-focus subject within the image data are highlighted.
