Abstract
A scanner control circuit comprises a digital line delay memory and a control circuit coupled to the digital line delay memory. The control circuit receives digital multi-channel image data having a channel-to-channel delay and corrects for said channel-to-channel delay. Each channel's image data is written into the digital line delay memory at an address in the digital line delay memory corresponding to the correct line number and is then read out of the digital line delay memory for processing. The scanner control circuit operates to allow scanning of an object bi-directionally.
