Abstract
An image input scanner includes a linear array of photosensors to record images, such as in a digital copier or facsimile. A subset of the photosensors can be selected, depending on a particular situation, for recording images, while other photosensors are deselected. In this way, recording of 'blank' image data, such as would be caused when photosensors in the array are not exposed to a sheet passing relative to the array, is avoided. In one embodiment, the array includes a plurality of local clock drivers, each clock driver controlling image data readout from a subset of photosensors. When a subset of photosensors are selected for a given situation, only the clock drivers associated with the selected photosensors are activated.
