Abstract

PROBLEM TO BE SOLVED: To realize a precise focus detecting action based on the line-of-sight position of a user by executing it after a shift lens is moved. SOLUTION: By executing communication with a lens 17 by using a lens control circuit 2, it is decided whether a photographing lens is provided with a shift optical system (shift lens) which can be driven or not. When it is provided with the shift optical system, a shift action is executed by the shift optical system. Next, a focus detection area nearest to the line-of-sight position of a photographer (user) is selected or the focus detection area of a prescribed algorithm judged to be more proper is selected. Then, the selected focus detection area is stored in a selected line sensor and read out by using a focus detection circuit 6. Based on the A/D value of the output of the sensor, the focus detecting action is executed by the existing algorithm. Based on focus detection data obtained in such a way, lens driving amount is arithmetically operated. Thereafter, the lens driving amount obtained by the arithmetic operation is communicated to a lens control circuit 2 so as to drive the lens.

The camera has a photometric value calculating means for calculating a photometric value from the detection result of the brightness detecting means, and the shift lens control means after the brightness detecting operation by the brightness detecting means and before the exposure operation. 8. The camera according to claim 7, wherein the shift lens is returned to the initial position. 9. The camera has a memory for storing a correction amount corresponding to a shift amount of the shift lens by the shift lens control means, and the photometric value calculation means stores a brightness detection result by the brightness detection means. 9. The camera according to claim 7, wherein a photometric value is calculated using the correction amount stored in the memory.
