[Step 706] The same operation as step 606 is performed. [Step 707] When it is determined that the photographer is looking at the AF focus detection point, the line of sight 80
No. 2 determines that the input value of the sub electronic dial 10b is the correction value for the light adjustment correction, proceeds to step 708 and performs the correction, and when it is determined that the photographer is looking at a position other than the AF focus detection point, the line of sight 803 is , The input value of the sub electronic dial 10b is regarded as a correction value for exposure correction, and the process proceeds to step 709. [Steps 708 to 711] Above steps 608 to
The same operation as 611 is performed.

By using the embodiment described above,
Considering that the AF focus detection point represents the subject,
