Abstract

A number of applications employing lossy compression require that a mechanism be employed to control the size of a compressed image so that it does not exceed the capacity of a fixed-size buffer. This situation arises in digital cameras, where a user expects to store a predefined number of pictures into a fixed-size buffer, or in computer peripheral systems like a laser printer where a fixed-size buffer is used to store the rendered page image. We describe a fully JPEG compliant tow-pass scheme that can compress an arbitrary image to a predetermined fixed size file. The advantages of the proposed method are that it is fully compliant with the JPEG standard image compression algorithm and it requires a smaller working buffer than other rate- control schemes.
