Abstract:
1. A portable hand-held device with image capture and image projection functions, comprising: an optical element comprising a lens having a field of view and a principal optical axis; an image sensor comprising an array of pixels optically coupled to the optical element such that an image of an object can be captured by the image sensor through a first partial field of view of the optical element, the image sensor having a camera optical axis that is not coincident with the principal optical axis and being disposed in a first fixed position relative to and displaced from the principal optical axis; a light valve comprising an array of individually addressable pixels that are optically coupled to the optical element such that a light beam from each pixel can be projected on a screen by a second partial field of view of the optical element so as to form an image on the screen, the light valve having a projection optical axis that is not coincident with the principal optical axis and being disposed in second fixed position relative to and displaced from the principal optical axis.
