摘要： To suppress a difference in brightness and darkness in a captured image caused by a difference in an exposure start time by a rolling shutter even if the exposure period is not changed. Provided is an imaging device including a gain setting unit configured to set a gain for each line in which a plurality of pixels is arrayed, the plurality of pixels being two-dimensionally arranged in a matrix in an image sensor, on the basis of diaphragm drive information regarding a diaphragm drive locus representing a time-series change in a diaphragm value. Thereby, the difference in brightness and darkness in a captured image caused by the difference in an exposure start time by a rolling shutter can be suppressed even if the exposure period is not changed.

摘要： An imaging apparatus includes a focus detector configured to perform a focus detection based on a signal output from the image sensor corresponding to the first imaging, a calculator configured to calculate a first time corresponding to the second imaging, and a focus controller configured to perform a focus control for driving the focus lens to an in-focus position predicted at the first time based on a focus detection result. The calculator calculates the first time in accordance with whether the aperture control corresponding to the attached lens apparatus is a first aperture control for driving the aperture to a target aperture value via a predetermined aperture value from the aperture value before the aperture control or a second aperture control for driving the aperture to the target aperture value directly from the aperture value before the aperture control.

摘要： Techniques related to automatic aperture control for an imaging device are discussed. Such techniques may include implementing an aperture control value to adjust an aperture opening, measuring a rate of change in measured luminance at an image sensor in response to the aperture control value, and determining an aperture control hold value to hold the aperture opening at a current position using the aperture control value and the rate of change.

摘要： An object of the present invention is to accurately perform focusing adjustment so as to take a picture that is free of an image blur. A prohibition CCPU is provided for prohibiting a change operation of an image blur correction coefficient change means ICPU and a light amount adjustment operation of light amount adjustment means SNS, SDR, and STR from being performed at the same time. Thus, an operation for selectively changing an image blur correction coefficient stored in storage corresponding to movement of a zooming optical member and (or) a focusing adjustment optical member disposed in a focusing optical system is not performed while a photoelectric converting device or a photosensitive material disposed in the vicinity of a focusing plane of the focusing optical system is being performed.In addition, since the image blur correction coefficient is continuously changed, an image blur error is prevented even if the coefficient is changed.

摘要： A camera operable in shutter-priority automatic exposure mode comprises a photometric circuit, an exposure data memory circuit for storing information on a plurality of selectable diaphragm openings, and a control circuit for calculating a desirable diaphragm opening based on a shutter speed preset prior to an exposure and luminance data output from the photometric circuit, and determining an actual diaphragm opening based on a comparison between the calculated diaphragm opening and the selectable diaphragm openings. The control circuit checks whether the preset shutter speed is higher or lower than a predefined reference shutter speed and selects one of the selectable diaphragm openings that provides a higher shutter speed if the preset shutter speed is higher than the reference shutter speed, or selects one of the selectable diaphragm openings that provides a lower shutter speed if the preset shutter speed is lower than the reference shutter speed.
