Abstract
An imaging control device including: a control unit configured to perform control such that an exposure timing is synchronized with a timing of a peak of a detected flickering component on a basis of a period of the flickering component and the timing of the peak of the flickering component.
Claims18
An imaging control device, comprising:
- processing circuitry configured to
- determine that a shutter button is in a half-pushed state,
- in response to the determination that the shutter button is in the half-pushed state,
- calculate an initial phase of a flickering component of a signal component based on input image signals,
- estimate a frequency of the flickering component based on a frame rate of an image sensor and the calculated initial phase, and
- detect a timing of a peak of the flickering component,
- determine that the shutter button is in a fully-pushed state, and
- in response to the determination that the shutter button is in the fully-pushed state, synchronize an exposure timing with the timing of the peak of the flickering component on a basis of the frequency of the flickering component and the timing of the peak of the flickering component,
- wherein the processing circuitry is configured to detect whether the flickering component exists in each color of primary color signals of the input image signals.
An imaging control method, comprising:
- determining that a shutter button is in a half-pushed state;
- in response to the determination that the shutter button is in the half-pushed state,
- calculating an initial phase of a flickering component of a signal component based on input image signals,
- estimating a frequency of the flickering component based on a frame rate of an image sensor and the calculated initial phase, and
- detecting a timing of a peak of the flickering component;
- determining that the shutter button is in a fully-pushed state;
- and
- in response to the determination that the shutter button is in the fully-pushed state, synchronizing an exposure timing with the timing of the peak of the flickering component on a basis of the frequency of the flickering component and the timing of the peak of the flickering component,
- wherein the method further includes detecting whether the flickering component exists in each color of primary color signals of the input image signals.
A non-transitory computer-readable storage medium storing instructions, which when executed by at least one processor, cause the at least one processor to perform an imaging control method, the imaging control method comprising:
- determining that a shutter button is in a half-pushed state;
- in response to the determination that the shutter button is in the half-pushed state,
- calculating an initial phase of a flickering component of a signal component based on input image signals,
- estimating a frequency of the flickering component based on a frame rate of an image sensor and the calculated initial phase, and
- detecting a timing of a peak of the flickering component;
- determining that the shutter button is in a fully-pushed state;
- and
- in response to the determination that the shutter button is in the fully-pushed state, synchronizing an exposure timing with the timing of the peak of the flickering component on a basis of the frequency of the flickering component and the timing of the peak of the flickering component,
- wherein the method further includes detecting whether the flickering component exists in each color of primary color signals of the input image signals.
