Abstract
An imaging system includes a digital camera and illuminating devices. The digital camera includes an imaging optical system, a shutter, a shutter driving mechanism, an imaging element, an illumination control unit, and a wireless I/F. The shutter is a focal-plane shutter. In a case in which a main imaging operation is performed in a plural illumination control mode, the shutter driving mechanism drives the shutter to generate a transition period for which a partial exposure region is transferred to the lower side of an imaging area of the imaging element over time. The illumination control unit controls the emission times of the illuminating devices to be different times within the transition period.
Claims10
An imaging apparatus comprising:
- an imaging element that has an imaging area for capturing an image of an object;
- a shutter that generates a transition period for which a partial exposure region that is partially exposed in the imaging area is transferred over time in one direction from one end to the other end of the imaging area;
- and
- an illumination control unit that, in a case in which at least first and second illuminating devices that irradiate the object with illumination light are provided, controls first and second emission times of the first and second illuminating devices and controls the first and second emission times to be different times within the transition period.
A method for controlling an imaging apparatus comprising an imaging element that has an imaging area for capturing an image of an object, a shutter that generates a transition period for which a partial exposure region that is partially exposed in the imaging area is transferred over time in one direction from one end to the other end of the imaging area, and an illumination control unit that, in a case in which at least first and second illuminating devices that irradiate the object with illumination light are provided, controls first and second emission times of the first and second illuminating devices, the method comprising:
- a transition period generation step of allowing the shutter to generate the transition period;
- an illumination control step of allowing the illumination control unit to control the first and second emission times to be different times within the transition period;
- and
- an imaging step of allowing the imaging element to capture the image of the object during the illumination control step.
