Claim Text:
1. An endoscope camera, comprising: a cylindrical enclosure having an enclosure diameter; a rectangular array of imaging pixels formed on a planar substrate acting as a supporting frame for the array, which has a first side of a first length and a second side of a second length, wherein the first length is longer than the second length, and the array is mounted within the enclosure so that a plane face of the array is parallel to the enclosure diameter; a right-angle transparent prism having a rectangular entrance face, an exit face, and an hypotenuse configured to reflect radiation from the entrance face to the exit face, the entrance face having a first edge of the first length and a second edge of the second length, the prism being mounted within the enclosure so that the first edge is parallel to the enclosure diameter with the exit face cemented to the plane face of the array; and anamorphic optics, configured to receive incoming radiation from an object, mounted so as to transmit the incoming radiation to the array via the entrance and exit faces of the prism and to form an image on the array that is distorted responsively to an aspect ratio of the exit face.
