Paper Abstract

We have built a versatile Direct Memory Access Interface for IBM PC-AT compatible personal computers which can accept digital image data from a variety of high density slow scan image capture devices. Our first implementation of this design is tailored to the Hamamatsu Photonics Cooled CCD Camera, which is designed to capture very low light level, high resolution images with 12 bit dynamic range. The interface has been designed for camera format flexibility and can easily be configured for larger image arrays and up to 16 bits of dynamic range. The interface loads digital image data to both the PC memory and the on-board RAM of most graphics controllers, allowing realtime image display/update for many non-standard scan rate image capture devices. The interface also provides arithmetic processing for realtime dark current correction and frame integration.
