Claims12
A method, comprising:
- receiving a user selection of digital zooming in a camera;
- responsive to the user selection of digital zooming in the camera and without further user input, automatically generating plural images by capturing the images automatically in quick succession within a few seconds of receiving the user selection of digital zooming in the camera, transparently to the user;
- digitally zooming at least portions of at least some original images, each original image encompassing an original area, by removing a respective portion of each of the original images from the respective original image to render a respective cropped image of the original image and expanding remaining image pixels in the cropped image to fill an area equal in size to the original area;
- and
- superimposing at least some cropped images to produce an improved digital zoom image transparently to the user.
