ABSTRACT:
A conventional definition camera acquires video data relating to a portion of an image to be televised and stores the data in a higher definition capacity store. The camera is panned and tilted to acquire data relating to other parts of the image. A motion detector determines the degree of movement of the camera and controls the writing of data to the store. A spatio-temporal interpolator interpolates the video data to correct for spatial or sensitivity incompatibilities. The output from the store may again be spatio-temporally interpolated by an interpolator under control of the motion detector to compensate for movement within the image to be televised. In a further embodiment image data is acquired by a plurality of overlapping lower definition sources.
