Abstract
An exposure control apparatus includes a control amount converting table for storing data on a gain control amount associated with data on a detected quantity of incident light. On the basis of an output from the control amount converting table, light quantity gains of light quantity variable means, such as an iris, a shutter, an AGC amplifier, and so forth, are set. The level of a quantity of incident light coming through these light quantity variable means is detected, and the detected data is fed to correcting means. The correcting means corrects an error between data on the control amount of the light quantity gain output from the control amount converting table and an actual light quantity gain of the light quantity variable means. An output from the correcting means is fed to the control amount converting table.
