Abstract: A personal identification system based on the reading of multiple one-dimensional barcodes scanned from PDA/cell phone screen, which is a personal identification system applicable for reading multiple one-dimensional barcode on PDA/cell phone screen, comprises a multiple one-dimensional barcode generating system and a reading system of multiple one-dimensional barcode on PDA/cell phone screen, wherein said multiple one-dimensional barcode generating system is consisted of a data input unit and a barcode generating unit. The reading system of multiple one-dimensional barcode on PDA/cell phone screen is consisted of a PDA/cell phone reaction unit, a CCD camera, a frame grabber, an image processing unit, a barcode recognition unit and a data recording unit. The personal identification system based on the reading of multiple one-dimensional barcodes scanned from PDA/cell phone screen is useful as the mechanism for personal identification, certificates of purchase or checkoff.

Abstract: A digital image monitoring system with functions of motion detection and auto iris which aims at the requirement of video-recording monitoring for traffic facilities, home or company which is composed of CCD camera, lens, frame grabber, illumination—reflectance decomposition unit, illumination variation detection unit and motion detection unit. The frame grabber accompanies with the CCD camera and lens to take digital images continuously. Then the illumination—reflectance decomposition unit decomposes the captured digital image and transfers it into the illumination and reflectance spectrum to provide the illumination detection unit to analyze the illumination spectrum variation between two adjacent image frames and thus this spectrum variation is used to control the amplification or reduction of the iris; beside ,an object movement detection unit is provided to analyze the illumination variation of two adjacent films to judge if the object in the frame is moving .
