摘要： Flicker, which occurs in photographing of a moving image under lighting by a fluorescent lamp, is detected accurately. A common multiple of a light-emitting period {fraction (1/100)} sec in a region where a frequency of a commercial AC power supply is 50 Hz, a light-emitting period {fraction (1/120)} sec in a region where the frequency is 60 Hz, and 1/fp according to a frame rate fp is defined as a synchronous period. An exposure condition determining unit decides an exposure condition on the basis of an image signal level at each synchronous period and feeds back the exposure condition to exposure control of a frame after the synchronous period. A synchronous level extracting unit extracts image signal levels for plural frames at each synchronous period and a synchronous judging unit judges a stability state of the levels. On the other hand, a flicker judging unit detects presence of a section where a fluctuation in an image signal level between adjacent frames is large in the synchronous period. When the synchronous level judging unit confirms that an exposure stable state is realized, the flicker judging unit makes a result of judgment on flicker based on the fluctuation of a signal level in the synchronous period effective.

摘要： In an NTSC imaging apparatus, the shutter speed is set to a first value other than N/120 second, and a flicker detecting process is performed on a video signal obtained at the first shutter speed to extract a particular frequency component. If the level of this frequency component is higher than a threshold value, it is determined that photographing is conducted under fluorescent light with a power supply frequency of 50 Hz. If it is not higher than the threshold value, the shutter speed is set to a second value other than N/100 second, and a flicker detecting process is performed on a video signal obtained at the second shutter speed to extract a particular frequency component. If the level of this frequency component is higher than a threshold value, it is determined that photographing is conducted under fluorescent light with a power supply frequency of 60 Hz.

摘要： The levels of video signals obtained by photography at a relatively high shutter speed and photography at an ordinary shutter speed are made approximately equal at all times, irrespective of any change in the characteristics of an AGC. Photography performed at a relatively high shutter speed of one time in a plurality of fields and photography is performed at an ordinary speed at other times is repeated periodically. One field of a luminance signal obtained by photography at the relatively high shutter speed is integrated by a first integrating circuit, and one field of the luminance signal obtained by photography at the ordinary shutter speed is integrated by a second integrating circuit, wherein the luminance signals represent contiguous images. A signal representing the difference between these integrated values is produced by a difference detecting circuit. The difference signal serves as a gain correction signal. The gain correction signal is added to a gain control signal, and the resulting signal is applied to the AGC. The gain control signal of the AGC is corrected by the gain correction signal so that the average level of the video signal resulting from photography at the relatively high shutter speed and the average level of the video signal resulting from photography at the ordinary shutter speed become approximately equal in the AGC.
