ABSTRACT:
An image sensing apparatus according to one mode of the present invention enhances precision of WB adjustment to thereby obtain an image having an appropriate WB, and comprises an image signal processing circuit which adjusts the WB with respect to an image signal output from an image sensing element based on a WB gain, a ROM which stores at least a WB correction coefficient correspondence table, and a WB modification coefficient correspondence table, and a microcomputer which calculates a WB correction coefficient corresponding to a diaphragm value, and a WB modification coefficient based on the correspondence tables and which multiplies the WB gain by the WB correction coefficient and WB modification coefficient to thereby obtain a value as a digital gain and which executes a control in such a manner as to adjust the WB based on the digital gain.
