Recording materials are converted in a direct thermal imaging apparatus to time temperature indicators by exposure to heat from the thermal print head of a direct thermal printer. Methods for converting a recording material to a time temperature indicator comprise heating the recording material with a direct thermal imaging apparatus. The recording material contains an indicator compound which is convertible from an inactive state to an active state when heat is applied thereto by a direct thermal imaging apparatus for less than one second. Time-temperature indicators with active indicator compounds in a printed pattern are formed by a direct thermal imaging apparatus.

The multiplexed motion picture camera of claim 3, wherein the relay lens is movable, such that its position is adjustable. 7. The multiplexed motion picture camera of claim 1, further comprising at least one shutter disposed between the beam splitter and the first or second scene light capture means. 8. The multiplexed motion picture camera of claim 1, wherein the scene light capture means are selected from a group of image recording devices consisting of black and white or color photographic film camera mechanisms, electronic imaging camera mechanisms and camera mechanisms capable of recording a motion picture sequence on film or capturing a motion picture sequence capable of being recorded on an electronic format. 9. The multiplexed motion picture camera of claim 8, wherein the first and second scene light capture means are photographic film camera mechanisms each having a shutter and an intermittent film advance mechanism. 10. The multiplexed motion picture camera of claim 9, wherein the control means advances film in the first scene light capture means at a speed greater than the second scene light capture means. 11. The multiplexed motion picture camera of claim 9, wherein the control means comprises a motor connected to each of the scene light capture means through a power train arranged to provide mechanical motion to the shutter and film advance mechanism in each of said scene light capture means, the arrangement of the power train determining when the first exposure cycle occurs relative to when the second exposure cycle occurs. 12. The multiplexed motion picture camera of claim 9, wherein the control means comprises a separate motor connected to each of the scene light capture means, and an electronic means for separately controlling the speed and timing of the motor associated with each of the scene light capture means, such that each of the scene light capture means is separately adjustable. 13. A multiple image device for use with an objective lens and a plurality of camera mechanisms, each of said camera mechanisms having a lens mounting port and at least one image detecting plane, said device comprising: a lens mounting port for mounting said objective lens; a primary beam splitter for receiving a scene light beam from said objective lens and dividing said scene light beam into at least two secondary scene light beams; a plurality of lens mount fittings for connecting said camera mechanisms to the device such that said objective lens forms an image in the image detecting plane of each of the camera mechanisms, said lens mount fittings being engageable with the lens mounting port on the cam
