Real time digital recording system for thermovision data
TLDR
In this article, a computer that receives and stores bursts of high speed data from the digitized analog output of an infrared camera and simultaneously transfers a uniform flow of the data at a lower data rate to a digital tape recorder is realized.Abstract:
Direct, real time digital data recording of thermal imagery is realized by the utilization of a computer that receives and stores bursts of high speed data from the digitized analog output of an infrared camera and simultaneously transfers a uniform flow of the data at a lower data rate to a digital tape recorder. The computer receives data only during camera active scan periods but transfers data to the recorder continuously. By making the computer output data rate substantially equal to the average input data rate real time recording is achieved. Full utilization of the data handling capacities of both the computer and the lower speed recorder is accomplished by digitizing the camera output signals in 8 bit words, combining pairs of 8 bit words for 16 bit word processing in the computer and reconverting the computer output data to 8 bit words for recording by the digital tape recorder.read more

Patent
A method of searching recorded digital video for areas of activity
TL;DR: In this paper, a method of scanning recorded video images of a scene to locate those images in which there is a predetermined amount of activity is proposed, where a threshold test is applied to each image as a measure of the activity occurring in the scene at the time the image is obtained and the results of the test are stored with the image in a memory of an image processing system.

Patent
Method of recording video signals within a predetermined bit/unit time recording rate
TL;DR: In this article, the video signals are split into two channels and applied to a head wheel having four transducer heads in time-expanded form, with the wrap angle of the tape exceeding 180°, time expansion being carried out at a rate related to the excess wrap angle, so that the track of recording will have a smaller recording angle than heretofore.
