Abstract

An image sensor array system is addressable to enable readout of randomly selected image data from any one or more individual sensor cells, for any selected image area (13), or for the entire image area (15). The sensor array (16) is accessed by horizontal and vertical readout circuits (22 and 24) under the control of address signals from an address unit (20). Location signals, from a source (12), indicative of a selected image area (13) may be used by the address unit (20) to provide address signals representative of the location of a specific sensor cell or area (13) of the array including image data of interest. Under the control of the address signals, image data from cells at the intersection of array lines and columns are sampled by sampling devices (26-32) and provided as output signals representative of the selected portion of the image area at an output port (34). Simplified readout can be provided for oblique line components of images. Differing input bus widths enable different levels of cell or line selection.
