Then, the approximation of the outline of the left ventricle is executed concerning each intermediate picture by a straight line connecting the respective equal dividing points. The approximation is samely executed by the straight line for the set outline of the left ventricle in the ED picture. Then, the obtained respective approximated outlines of the left ventricle are regarded as the outlines of those pictures and the capacity of the left ventricle is calculated concerning each picture. After that, a curved line for the change in the lapse of time is displayed on a TV monitor 4. Thus, the objective error can be suppressed to the irreducible minimum and in such a case, the outline is set by an operator only concerning the two pictures of the ED and ES. Then, operation is made easy and speedy in comparison with conventional technique.

Abstract: PURPOSE:To minimize a jitter by discriminating the relation of the generating position of the reproduced pilot signal and the position of the recorded head and executing the reproduction with the same head as the head used at he time of recording, in the four head helical scannings VTR. CONSTITUTION:A timing pulse to change over from a terminal 1 at the time of reproduction to an R head is inputted, and inputted through an differentiating circuit 2 to an f-V converting circuit 3.

Thus, the tracking signal and the speed error signal of the speed control circuit 11, which are obtained from a phase control circuit 12 controlled by using a control signal, are synthesized, and a little quantity of jitters can be reproduced by the same head as the one at the time of recording.
