ABSTRACT:
A sensing device for generating an output signal corresponding to an input signal which comprises a substrate, an array of sensor elements for receiving the input signal and transfer members located on the surface of the substrate and interposed between the sensor elements. The sensor elements have their barycenters distributed on the surface of the substrate in a random non-periodic pattern. The transfer members are coupled to the sensor elements and generate the output signal.
The sensing device is incorporated in an apparatus which generates an output signal from an input image wherein the output signal is substantially free of detectable aliases. The apparatus includes an image pick-up device for viewing the input image and transmitting radiation to the image sensing device, an analog-to-digital converter for converting the analog signal from a sensing device to a digital signal, a position encoder, an interpolator and a memory means for storing the output of the interpolator. The position encoder is provided with a plurality of storage addresses for storing digital signals each having a value corresponding to the intensity of the radiation incident on a corresponding sensor element, and the interpolator generates a plurality of signals corresponding to intensity values intermediate to those stored in the storage addresses of the position encoder.
