Abstract
The present invention is directed to a method and apparatus for encoding a series of still images. The first image is captured and stored, then for each subsequent image of the series, that image is captured and compared to the first image or the previous image and difference information between the first or previous image and each subsequent image of the series is stored, resulting in one output file that contains the base image and difference information for each subsequent image, thereby reducing the amount of storage needed to store a series of images.
Claims20
A method of compressing a series of still digital images comprising:
- capturing a first digital image of a series of digital images;
- storing said first digital image in an output file;
- capturing at least one more digital image of said series of digital images;
- and
- for each digital image of said at least one more digital image:
- comparing said each digital image to said first digital image to create a set of difference data;
- appending said set of difference data to said output file.
A method of compressing a series of still digital images comprising:
- capturing a first digital image of a series of digital images;
- storing said first digital image in an output file;
- capturing at least one more digital image of said series of digital images;
- and
- for each digital image of said at least one more digital image:
- comparing said each digital image to a previous digital image to create a set of difference data;
- appending said set of difference data to said output file.
A camera comprising:
- an image sensor;
- an image processor connected to said image sensor;
- a memory connected to said image processor;
- logic in communication with said image processor configured to capture a series of still digital images from said image sensor;
- and
- logic configured to compress said series of still digital images by recording a base image and difference information for each subsequent digital image in said series of still digital images.
