ABSTRACT:
An image sensing apparatus comprises: an image sensor which converts an optical image of an object into an electrical signal; a first amplifier which amplifies the electrical signal by a first gain; a second amplifier which further amplifies the amplified electrical signal by a second gain that is changeable in finer steps than the first gain; and a control unit which obtains a third gain based on an quantity of incident light to said image sensor and adjusting the first and second gains so that a sum of the first and second gains equals the third gain. The control unit adjusts a gain component of the third gain, which cannot be adjusted by the first gain, using the second gain, and ensures the third gain by adjusting only the second gain when a brightness change more than the preset brightness difference does not continue for not less than a preset time.
