APPARATUS FOR HIGH SPEED IMAGE ACQUISITION USING MULTI FRAME MEMORY

摘要

PURPOSE: An apparatus for high speed image acquisition using multi frame memory is provided to enable host computer to read memory of other frame while A/D converter is writing on the frame memory. CONSTITUTION: An apparatus for high speed image acquisition includes a camera, an A/D converter, a multi frame memory block(21), a host computer, and a frame memory selector(22). The camera(10) takes an analog image. The A/D converter converts the analog image signal to digital image data. The multi frame memory block(21) stores the digital image data converted in the A/D converter. The host computer reads the digital image data stored in the multi frame memory block(21) by way of a PCI bus. The frame memory selector selects a frame memory not used by the host computer and acknowledges the frame memory to the A/D converter(21). The frame memory selector(22) selects a frame memory used by the host computer and acknowledges the frame memory to the A/D converter(21).
