Abstract: An image capturing apparatus communicates with a strobe device used for image capturing and acquires preliminary light emission result information performed by the strobe device. A light control process for determining a light amount of main emission by the strobe device for main image capturing is executed based on the acquired preliminary light emission result information. In a case where an image capturing frequency for repeating image capturing is higher than a threshold value, information which is different from information on the light amount of main emission and is used for settings of preliminary light emission or main light emission is communicated by dividing the information into information acquired by a first communication processing before preliminary light emission and information communicated by a second communication processing after preliminary light emission.

Abstract: Embodiments of the disclosure provided herein generally relate to methods and video system components that have integrated background differentiation capabilities that allow for background replacement and/or background modification. In some embodiments, undesired portions of video data generated in a video environment are separated from desired portions of the video data by taking advantage of the illumination and decay of the intensity of electromagnetic radiation, provided from an illuminator, over a distance. Due to the decay of intensity with distance, the electromagnetic radiation reflected from the undesired background has a lower intensity when received by the sensor than the electromagnetic radiation reflected from the desired foreground. The difference in the detected intensity at the one or more wavelengths can then be used to separate and/or modify the undesired background from the desired foreground for use in a video feed.

Abstract: An image pickup apparatus which reduces the time required to achieve correct exposure while reducing deterioration of an aperture and changes in the exposure of an image. A correct exposure is calculated from a subject brightness. A setting value of the aperture is discretely calculated from the correct exposure. A first target value is calculated from a present value of the aperture and the correct exposure. A second target value closer to the setting value than the first target value, is calculated from the present value of the aperture, correct exposure, and first target value. While the aperture is driven to reach the second target value from the first target value, shutter speed and/or gain is changed. The aperture is driven at a first drive speed to reach the first target value and then driven at a second drive speed to reach the second target value.
