Preliminary
Data Sheet
SPCA504A
1. General description
The SPCA504A is a digital camera processor chip that provides a complete solution for dual mode camera
applications. This chip integrates image sensor interface, digital video input interface, color image processor,
storage media controller, JPEG image compression engine, USB interface, and a built-in micro-controller. The
SPCA504A supports both CCD and CMOS image sensors up to 1.1M and 2.0M pixels respectively. It is
designed to fulfill all the requirements for the dual mode camera applications. The SPCA504A camera processor
chip includes not only the latest technology, but also the full services and support of Sunplus.
2. Feature
The main functions of the SPCA504A includes:
● DSC mode
: capture one frame each time
● Video clip mode : capture a video with frame rate 15~30 frames/sec
● PC-camera mode : 30 frames/sec for CIF size, 20 frames/sec for VGA size
The SPCA504A chip has many image-processing functions that include:
● High quality color interpolation
● Two-dimensional edge enhancement
● Bad pixels concealment
● AE/AWB parameter windows cover full range of the sensor
The SPCA504A supports image CCD/CMOS sensors up to 1.1M/2.1M pixels. Some of them are listed below.
