Abstract: A foveated electronic camera employing a spatial-frequency spectrum analyzer and data-reduction means utilizing movable spatial windows for converting a high-resolution, wide field-of-view image into a group of subspectrum band images ranging in resolution and field of view from a lowest-resolution image of the entire field of view to a highest-resolution image of a selectably positionable smallest spatial subregion of the entire field of view. Such a camera is useful in a surveillance camera system and in a robotic system, by way of examples.

Abstract: First processing means 202 converts a high-resolution, wide field of view image signal into a series of output signals, ranging in resolution from high resolution, L0, to low resolution, GN, representing the same field of view. These signals, except for GN, are further processed by second processing means 204-0 to 204-(N-1) to produce final output signals ranging in field of view from a low resolution image of the entire field of view, GN, to a highest resolution image of a selectably positionable smallest spatial sub-region of the entire field of view, L'0 (see Figure 5). The arrangement is such that each of the final output signals L'0-LN-1, GN comprises the same number of pixels. This eases subsequent computing requirements. The technique finds a use in foveated electronic cameras which may be used in surveillance or robotic systems.

Abstract: An electronic camera (100) with concentration of the resolving power by area (Fovea control) uses a space frequency spectral analyser (202) and a data reduction device (204-0, etc.), which works with moveable space windows, to convert an image which has high resolution and corresponds to a broad field of vision into a group of images which each contain a partial band of the spectrum. The resolution and field of vision of these partial band images range from a very low resolution image of the whole field of vision to a very high resolution image of a very small partial area, the position of which can be selected, of the whole field of vision. Such a camera is useful, for instance, in a surveillance camera system or robot system.
