Paper Abstract

Key progress in the development of non-TV format CCD cameras has been made in high- speed scanning rate applications. VGA format has become an industrial standard for fast speed machine vision applications. While it is important to operate a camera in high speed applications with asynchronous reset, electronic shutter, or variable integration functions in order to capture dynamic motion, conventional strobe light applications are also still important. A combinatorial-scan CCD provides VGA and high speed scanning as well as frame mode interlace scanning for such applications. The main issues of this study are: (1) the structure of combinatorial-scan CCD's, (2) a fast dump structure to operate partial scan functions and asynchronous read-out control, (3) normal interlace operation with frame mode for strobe light applications, and (4) digital processing for dual channel or special functions to achieve fast frame mode. The first model was developed for the VGA format with a single- channel CCD output requiring scanning twice that of a normal CCD. The second model studies the combination of progressive and interlace scan functions. The third model has built- in digital processing and frame memory to capture the dual channel outputs of the CCD and scan-convert to various formats.
