Abstract
Abstract A fast frame recorder records a scene at a fast frame rate and displays it at a slower frame rate to produce a slow motion replay of the scene. The recorder includes a technique for recording a plurality of split frames of the scene during each frame period to effect an increased frame rate and for displaying the split frames of the scene on a video monitor either simultaneously or sequentially.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
233 words
Video reproduction apparatus comprising: an imager including an array of photosites arranged in rows thereof; means for reading out said array of photosites in blocks of photosites wherein a plurality of said blocks are each comprised of a respective plurality of photosite rows within each block to produce an output frame signal comprised of blocks of information in a serial format with each block of information being comprised of a plurality of parallel lines of video information that correspond to the photosite rows in each block; means for selecting a number of said blocks of photosite rows of a frame signal for a readout as a partial frame wherein the total number of blocks in a frame signal divided by said selected number of blocks is an integer N; means for producing successive pluralities of partial frames of information by reading out said selected number of blocks N times for each frame signal of said imager; a video display; control means for controlling said display to selectively operate in a first mode wherein said N partial frames of a frame signal are displayed simultaneously on said display and in a second mode wherein said N partial frames of a frame signal are displayed sequentially on said display such that only one said partial frames is displayed on said video display at any time and each of said N partial frames are displayed consecutively.

Claim 3
Dependent Claim
91 words
The apparatus of claim 1 including magnetic tape record/reproduce means for sequentially recording and reproducing said partial frames of information longitudinally on magnetic tape; memory means for storing said partial frames of a frame signal reproduced from said magnetic tape; and wherein said control means includes means for selectively reading out said memory means in said first mode to simultaneously display on said display all of the partial frames of a frame signal and in said second mode to sequentially display on said display each partial frame of a frame signal.
Claim 4
Dependent Claim
38 words
The apparatus of claim 1 wherein said video display has a display region including partial display regions and wherein in said second mode said partial frames are sequentially displayed in the same partial display region of said display.
