ABSTRACT:
An image sensor comprises a linear image sensor including several blocks of photo sensing elements, switching elements connected to the photo sensing elements respectively, and common signal lines connected to the blocks of photo sensing elements. In a crosstalk cancelling method for the image sensor, a dimensionless value representing the width of variation of the output signal due to crosstalk is defined as a gradation reproduction rate, and the sensor output is corrected according to the gradation reproduction rate. The gradation reproduction rate is determined irrespective to the total number of photo sensing elements; that is, it is determined only by layout of the wiring conductors. Therefore, by arranging the matrix wiring conductors which are electrically equal to one another in the effect of crosstalk, the crosstalk with the matrix wiring conductors can be generally evaluated and controlled irrespective of the design, and the output from which the effect of crosstalk is eliminated can be provided by simple operation.
