Patent Images
1. A motion analysis system comprising:
- a first motion video imager;
a second motion video imager;
means for continuously reading out each of said video imagers simultaneously at the same frame rate of F frames per second, where F is selectively variable, in a block format in which a frame of video information comprises a sequence of blocks of parallel lines of video information which have been read out simultaneously; and
means for recording every other frame from each of said first and second imagers in interleaved fashion on the same magnetic tape, each of said frames on magnetic tape being recorded in a plurality of parallel recording tracks in a sequence of blocks of parallel lines of video information.

Abstract
A motion analyzer in which full frames of video information from two video imagers are recorded in interleaved fashion on magnetic tape. The motion analyzer records at multiple frame rates in a block sequential format in which blocks of parallel lines of video information are recorded sequentially on magnetic tape. Frames of video in block format from one imager are alternately recorded on magnetic tape with frames of video in block format from the other imager. Although the effective recorded frame rate for each imager is one-half of the analyzer frame rate, each recorded frame has been exposed at the analyzer frame speed.
