A method is disclosed for producing signals representative of an image of a scene including the following steps: providing an image sensor with a lenticular lens pattern thereon, and projecting the image onto the image sensor via the lenticular lens pattern, the image sensor having a pixel element pattern and the lenticular lens pattern having diamond shaped lenticles and being diagonally oriented with respect to the horizontal scanning direction of the pixel element pattern; and producing image-representative signals by reading out signals from the pixel elements of the image sensor.

Apparatus and method for producing video signals

A method for converting an encoded digital video signal from a decoded relatively lower frame rate to a decoded relatively higher frame rate, including the following steps: deriving, from the encoded video signal, at the relatively lower frame rate, a decoded high resolution component and a decoded low resolution component; increasing the frame rate of the decoded low resolution component by interpolating successive frames of the decoded low resolution component; increasing the frame rate of the decoded high resolution component by duplicating frames of the decoded high resolution component; and obtaining an output relatively higher frame rate video signal by combining the increased frame rate low resolution component and the increased frame rate high resolution component.
