Abstract: Outputs from an array of input signals are amplified by an amplification section, sampled and multiplexed onto an analog bus. Amplifiers in the amplification section are segregated into groups. When the amplifiers are in a first mode, as indicated by a binning signal, the amplifiers within each group are electrically isolated from another and function independently from one another to provide a high resolution output signal. When in a second mode, amplifiers within a group operate as a single unified amplifier that averages the inputs for that group to provide a single output. Thus, in this second mode of operation, readout speed may be improved while increasing the signal-to-noise ratio of each input signal relative to the first mode of operation.

Abstract: An electronically and mechanically expandable camera in which a tubular metal casing having removable front and back plates has a CCD image sensor mounted on a secondary front plate removably received within the casing for a direct thermal path to the casing. A driver board is removably receivable at a position between the secondary front plate and the back plate. A logic board is removably receivable at a position between the driver board and the back plate. The camera's functions may be expanded or altered by adding option electronic board modules between the logic board and the back plate of the camera, or by reconfiguring the logic board or by adding a different image sensor. All of the components within the camera, all of the enclosure elements and all of the mounting hardware used in the camera can be easily and conveniently changed as desired.
