Image sensing device, linear sensor for use in the image sensing device, and method of driving the linear sensor

摘要

A linear sensor includes first, second, and third linear sensor sections each composed of a linear array of sensor elements, wherein the linear arrays of sensor elements are spaced seven lines apart from each other. In operation, an image is sensed while moving the linear sensor three lines at a time. The output signals of the respective linear sensor sections are adjusted in terms of the timing relative to each other by a timing adjustment circuit. This allows the linear sensor to sense an image at a higher scanning speed and thus for a shorter time period.
