scope:
Applies to the assessment of characteristics of automatic functions which are implemented in colour video cameras and camera-recorders. The performance to be assessed in this standard is limited to automatic functions relating to light input from the lens and to the electronic output from video cameras and the video camera portions of camerarecorders. This standard defines test patterns, measurement contiions, methods of measurement and the presentation of measured results so as to make possible the comparison of the measurement results. This standard intends to provide an objective method of measurement for each characteristic of the automatic functions but the results of objective measurement may not correlate well with the subjective assessment of autmatic functions. It does not specify limiting values for the various characteristics related to automatic functions.
