Paper Abstract

This paper presents the real-time implementation of an auto- white-balancing and an auto-exposure algorithm on the TI TMS320DSC21 platform. This platform is a power-efficient single-chip processor that has been specifically designed for digital still cameras. Its architecture consists of five subsystems including an ARM micro-controller, a DSP core, a memory subsystem, two co-processors, and an imaging peripherals subsystem. Due to the memory constraints, the algorithms were modified to allow their real-time implementation of the processor, i.e. a processing rate of 30 frames per second. These modifications are discussed in the paper. The details of the algorithms are reported in an accompanying paper presented in the SPIE conference 4669B.
