Abstract: An image capture apparatus sets an amount of exposure on an image sensor based on luminance information on an object field, calculates an expected signal level value that is an expected value of luminance signal level that is expected to be output from the image sensor when the image sensor is exposed at the set amount of exposure, compares the expected signal level value with an actual signal level value that is an actual value of luminance signal level output from the image sensor when the image sensor is exposed at the set amount of exposure, and sets a gain based on a result of the comparison.

Abstract: An image pickup apparatus including a photoelectric conversion element, first, a shutter speed for still-image pickup is set. Next, an image-pickup frame rate is set on the basis of the shutter speed for still-image pickup. Then, an operation of the photoelectric conversion element is controlled such that picked-up images are output at the set image-pickup frame rate. When the image-pickup frame rate that is set is higher than a moving-image-reproducing frame rate, a frame for use in a moving-image reproduction is generated from a plurality of frames of the picked-up images and reproduction is performed at the moving-image-reproduction frame rate.

Abstract: An object of the present invention is to suitably perform a zooming control operation in the case that a zoom ring is provided at a lens-side portion and zoom switches are provided at a camera-body-side portion of a lens-interchangeable video camera. To achieve this object, in the case-that no zoom lens stop request is provided from the camera-body-side portion, it is judged from information sent from the camera-body-side portion which of a tele direction and a wide direction the moving direction of the zoom lens group is. Moreover, when the zoom angle is not placed at a tele end or at a wide end, lenses are driven by calculating data for driving the lenses. Thereafter, tele information is set or cleared according to whether the zoom lens group is placed at the tele end. Subsequently, zoom-ring operating information is detected. The detected zoom-ring operating information is sent to the camera-body-side portion.
