An image pickup apparatus for use in, for example, a camera, comprising: a solid-state image pickup device such as the CCD type or frame transfer type for converting an optical image to an electric signal; a readout unit for reading out the electric signal formed in the image pickup device at the speed corresponding to the scanning speed of the standard television system; and a readout controller for setting the readout speed in the vertical direction by the readout unit to be higher than the vertical scanning speed of the standard television system with respect to at least a partial interval in the vertical scanning interval. A quantity of image which is formed in the image pickup means is controlled by an iris or shutter or the like by use of the image signal which was read out by the readout controller at a high speed. With this apparatus, object data regarding photo metering or distance metering or the like can be obtained at a high speed, so that the discriminating operation for the photo metering or distance metering or the like and the control operation can be performed at a high speed.
