摘要： A panoramic camera has a camera housing rotatable about an axis of rotation that defines a viewpoint which points along a radial optical path that object rays traverse as the camera is rotated about its axis; a lens assembly having an optical path and a front nodal point mounted for rotation with the camera housing with the optical path of the lens offset from the radial optical path; a specular assembly including an object specular member along the radial optical path mounted for rotation with the housing that cooperates with the lens assembly for gathering object rays that traverse the radial optical path and for deviating them along the optical path of the lens assembly in such a way that the front nodal point of the lens subassembly virtually appears to lie on the axis of rotation thereby eliminating image smearing; and has an ambient light responsive controller including an ambient light sensor mounted for rotation with the camera housing for automatically varying the speed of rotation in direct relation to the magnitude of the ambient light thereby eliminating both under- and over-exposure. Means are disclosed for allowing the selection of different near- and far-field object distances and for allowing framing (both vertical and angular) of the panoramic subject. In one embodiment, the specular assembly has object and lens mirrors that pivot between open and closed positions. Different embodiments have film or digital image recording devices.

摘要： An improvement is made in a camera wherein the exposure is controlled by an electronic circuit comprising a photoelectric element so situated as to receive a light reflected from the surface of photographic film in the camera.Conventional shortcomings of the above-mentioned camera that a time delay from operation of the electronic switching circuit to an actual completion of closing of the already opened shutter has been liable to cause an over-exposure and that an exposure period shorter than the delay has been impracticable can be eliminated by employing another photoelectric element which continuously receives a light from the object and influences a current to flow into a timer circuit.Moreover, by means of a change-over switch, the circuit is switched so as to be controlled substantially by the second photoelectric element in case the photographic object is so bright as to necessitate a high speed exposure faster than the time delay.
