Abstract

A digital camera has been designed based on a 1317 by 1035 pixel, full frame, CCD which offers the large area, high density sampling but with the options of programmable sub-area scanning and multiple independent x and y binning and programmable gain and offset. The sub-area scanning and binning can be used to increase the effective frame rate of the device for such applications as fast focusing and object location. The binning also provides greater sensitivity at the cost of spatial resolution, but is ideal in low light level applications such as fluorescence microscopy. The programmability of this camera permits the switching between the various clocking modes within a single frame time. Hence, the image can be auto-focused in sub-area scanning mode and then within a single frame time the full frame image can be acquired. The programmable clocking modes make this device ideal for quantitative imaging applications requiring a high throughput and the programmable gain and offset allow the user to fine tune the device for his specific needs. A description of the programmable microimager design and some initial measurements of noise, linearity, frequency response, and stability are presented.
