适用范围：This part of IEC 61146 applies to the assessment of characteristics of automatic functionswhich are implemented in colour video cameras and camera-recorders. The performance tobe assessed in this standard is limited to automatic functions relating to light input from thelens and to the electronic output from video cameras and the video camera portions ofcamera-recorders.This standard defines test patterns, measurement conditions, methods of measurement andthe presentation of measured results so as to make possible the comparison of themeasurement results.This standard intends to provide an objective method of measurement for each characteristicof the automatic functions but the results of objective measurements may not correlate wellwith the subjective assessment of automatic functions.It does not specify limiting values for the various characteristics related to automaticfunctions.
