An electronic camera includes a CCD imager. The CCD imager has an imaging surface in which two sensor areas are formed. A raw image produced in one sensor area is output from a channel CH1, and a raw image produced in the other sensor area is output from a channel CH2. The raw image from the channel CH1 is clamped by a clamp circuit at a clamp level LV1, and the raw image from the channel CH2 is clamped by another clamp circuit at a clamp level LV2. The clamp level LV1 matches an optical black level VCL of the raw image from the channel CH1. The clamp level LV2 matches a subtraction level “VCL−(VAL−VAR)” determined by subtracting a difference between a preliminary feeding level VAL of the raw image from the channel CH1 and a preliminary level VAR of the raw image from the channel CH2, from the black level VCL of the raw image from the channel CH1.
