Techniques are disclosed to improve quality of images that may be blurred
or underexposed (e.g., because of camera shake, taken in dim lighting
conditions, or taken of high action scenes). The techniques may be
implemented in a digital camera, digital video camera, or a digital
camera capable of capturing video. In one described implementation, a
digital camera includes an image sensor, a storage device, and a
processing unit. The image sensor captures two images from a same scene
which are stored on the storage device. The processing unit enhances the
captured images with luminance correction.
