发明名称 Video camera, printer apparatus and method of controlling same, and apparatus and method for detecting print inhibit signal
摘要 A reproduced still picture having a comparatively high picture quality is obtained irrespective of the luminance of the subject. In an interval photography mode, photography is performed one time in a plurality of fields at a relatively high shutter speed of +E,fra 1/250+EE of a second to obtained a first video signal, and photography is performed at an ordinary shutter speed of +E,fra 1/60+EE of a second in other fields to obtain a second video signal. These video signals are amplified at mutually different first and second amplification factors (6 dB and 18.4 dB, respectively) in conformity with the shutter speed, by an AGC. The first and second amplification factors are varied in dependence upon the illumination of the subject in such a manner that the average levels of the first and second video signals are maintained at a fixed level.
