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.
Claims21
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;
- means in communication with said image processor for capturing a series of still digital images from said image sensor;
- and
- means for compressing 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.
A method of decompressing a series of still digital images comprising:
- reading a first digital image from a series of digital images stored in a single file;
- storing said first digital image in a first output file;
- and
- for each subsequent digital image of said at least one more digital images stored in a single file;
- combining difference information related to said each subsequent digital image from said series of digital images with said first digital image creating a next digital image;
- storing said next digital image in a next output file.
