Abstract
Abstract A method and system for detecting object motion. Light emanating from a scene is filtered by a first filter and second filter and recorded by a first recording device and a second recording device, respectively. The signals from one of the recording devices is delayed with respect to the other recording device and then both signals are reproduced. At least one of the reproduced signals is again filtered and then both reproduced signals are then superimposed and a color reproduction suitable for detection by the human eye is produced. The reproducing means may be in the form of a phosphor screen which changes color as current density is changed, with each of the signals being alternately applied to the reproducing means. Alternatively, the recording device and reproducing means could be motion picture cameras and projectors or television cameras and receivers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A system for detecting motion of a portion of a viSual scene by processing sequential images of said scene, comprising: means for generating first and second discrete black and white filtered images of said scene, said means including associated filters to discriminate in favor of the lower frequency visible spectrum in the generation of said first image and in favor of the higher frequency visible spectrum in the generation of said second image; first and second scanning means for converting said first and second filtered images into corresponding electrical signals, respectively; first and second display means, for reestablishing said first and second filtered images from said electrical signals, said first and second display means being synchronously scanned with said first and second scanning means, respectively; combiner means for superimposing said reestablished first and second filtered images to produce a color display; and delay means for delaying one of said electrical signals to produce an area of color variation in said color display corresponding to displacement of a portion of said visual scene during the period of said time delay.
Claim 2
Independent Claim
179 words

Claim 5
Dependent Claim
26 words
Apparatus according to claim 1 in which said first and second scanning means and the corresponding display means comprise a pair of closed circuit television systems.
Claim 6
Dependent Claim
56 words
Apparatus according to claim 1 in which said first and second scanning means comprise a pair of black and white television cameras and said first and second display means comprise a pair of cathode ray tube displays each synchronously scanned with the corresponding camera, and said electrical signals are the video output signals of said cameras.
Claim 7
Dependent Claim
69 words
Apparatus according to claim 3 including third filter means at the output of said first display means, said third filter means having substantially the same optical pass-band as said filter means associated with said first filtered image, and fourth filter means at the output of said second display means, said fourth filter means having substantially the same optical pass-band as said filter means associated with said second filtered image.
Claim 8
Dependent Claim
206 words
A motion detecting system comprising: first means for recording first and second black and white images representative of an illuminated visual scene at corresponding first and second different times, said first image being recorded in light emphasized within a first passband and said second image being recorded in light substantially within a second passband different from said first passband; means for combining said first and second images, including display means for presenting said combined images visually; and first and second filter means associated with said combining means, said first filter being arranged to filter light from said first image and said second filter being arranged to filter light from said second image both before being combined for said display, said filters having different passbands, the lower pass-band filter being applied to the light from the one of said images recorded with emphasis on the lower of the two passbands of emphasis associated with said image recording, said display reproducing the colors of said visual scene and also exhibiting color disparities in areas of said scene wherein said first and second images are not congruent thereby to detect motion of any portion of said visual scene in the time between recordation of said first and second images.
