Abstract
Abstract An electronic camera includes a photosensor array that is supported by a housing. The photosensor array includes a plurality of binary diffractive lens elements for forming a substantially identical light image on laterally spaced areas of a surface respectively. A plurality of photosensors are disposed on the surface within the laterally spaced areas for receiving different portions of the light image respectively such that the photosensors in aggregation receive substantially all of the light image. The photosensors can have constant spacings therebetween, and the lenses have spacings therebetween that increase away from a predetermined point in the array. Alternatively, the lenses can have constant spacings therebetween, and the photosensors have spacings therebetween that increase away from a predetermined point in the array. As another alternative, the lenses and the photosensors can have constant spacings therebetween, and the lenses have focal points with spacings therebetween that increase away from a predetermined point in the array. The camera further includes a liquid crystal panel that is supported by the housing for displaying a received video signal. The photosensor array is substantially transparent, and the liquid crystal panel is disposed behind and visible through the photosensor array.
