Abstract
A method of compensating for camera shake includes reading a sequential series of images from an image sensing array, establishing a sharpness value for each of the sequential series of images, and performing an image selection based upon each sharpness value. The sharpness value is calculated for each image of the sequential series thereof during the reading.
Claims27
A method of compensating for camera shake comprising:
- reading a sequential series of images from an image sensing array, using a controller;
- storing image data from the image sensor array into a buffer;
- calculating statistics on the image data, using the controller, to analyze a frequency variation across the image sensor array;
- after the buffer is filled to a predetermined point, establishing a sharpness value for each image of the sequential series thereof based on the calculated statistics, using the controller;
- and
- performing an image selection based upon each sharpness value, using the controller;
- the sharpness value being calculated for each image during the reading.
