Claims
- 1. An image sensing apparatus comprising:
- (a) image sensing means for photoelectrically converting an image light incident from a subject;
- (b) gain control means for controlling a signal gain of an output of said image sensing means;
- (c) mode specifying means for selectively specifying a still-image photographic mode and a motion-image photographic mode; and
- (d) speed control means for increasing gain control speed of said gain control means when said still-image photographic mode is specified by said mode specifying means.
- 2. An image sensing apparatus according to claim 1, wherein said image sensing means includes a charge-coupled device.
- 3. An image sensing apparatus according to claim 1, wherein the control characteristic includes an amplification degree.
- 4. An image sensing apparatus, comprising:
- (a) image sensing means for obtaining an image signal;
- (b) gain control means for controlling a signal gain of an output of said image sensing means;
- (c) signal processing means for performing signal processing to an output signal of the gain control means;
- (d) mode specifying means for specifying a still-image photographic mode and a motion-image photographic mode; and
- (e) speed control means for increasing gain control speed of said gain control means when said still-image photographic mode is specified by said mode specifying means.
- 5. An apparatus according to claim 4, wherein said image sensing means includes a charge-coupled device.
- 6. An apparatus according to claim 4, wherein the signal processing means includes means for forming a motion-image signal and a still-image signal from the output of the gain control means, and wherein recording means records the still-image signal in a still-image recording area of a video track formed obliquely with respect to a longitudinal axis of a magnetic tape, and records the motion-image signal in a motion-image recording area of the video track, the still-image recording area and the motion-image recording area being formed adjacent to each other on a single video track.
