Abstract
Abstract A CCD driving circuit for reading and outputting data from a plurality of CCD sensors, each CCD sensor being actuable to convert an image into data by first optically sensing the image during a first time period and thereafter converting the optically-sensed image into data during a second time period, including a driving arrangement for actuating the CCD sensors such that the first time periods associated therewith are staggered so that the second time periods associated therewith do not overlap each other. A multiplexing arrangement is provided for multiplexing and outputting the data read from each of the CCD sensors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
A CCD driving circuit comprising circuit means for reading and outputting data from a plurality of CCD sensors which are each actuable to convert an image into said data by first optically sensing the image during a first time period and thereafter generating said data based on the optically-sensed image during a second time period, said circuit means including driving means for actuating said plurality of CCD sensors such that the first time periods of said CCD sensors are staggered so that the second time periods of said CCD sensors will not overlap each other, and multiplexing means for multiplexing and outputting said data read from each of said CCD sensors, wherein said driving means includes a counting circuit for periodically generating a first read starting signal which is applied to a first of said CCD sensors, and a plurality of time watching circuits which are each responsive to said counting circuit and which each supply to a respective said CCD sensor other than said first CCD sensor a respective further read starting signal at a point in time delayed by a respective unique time interval from each said first read starting signal.
Claim 2
Dependent Claim
