ABSTRACT:
In an image sensing apparatus comprising an array of image sensing elements, first and second shift registers are provided, each having stages divided into first and second sections, the stages of the first section of the first and second shift registers corresponding to odd-numbered elements and even-numbered numbered elements of the array, respectively. During each line scan, a transfer command pulse is generated to turn on gates to transfer image signals developed in the array to the corresponding stages of the first shift register of each shift register. A calibration sequence is stored into the second section of each shift register when the gates are in a turn-off state, and the shift registers are alternately driven to deliver the image signals followed immediately by the calibration sequences. The image signals delivered from the shift registers are combined to produce a complete video line signal. A difference in amplitude between the calibration sequences delivered respectively from the shift registers is detected for controlling amplitudes of subsequently delivered image signals.
