Abstract:
1. An electronic camera, comprising: an imager having an imaging surface in which a first photoelectric conversion area and a second photoelectric conversion area are formed and a first output path and a second output path assigned to said first photoelectric conversion area and said second photoelectric conversion area, respectively; a first driver for outputting from said first output path a first partial image produced in said first photoelectric conversion area; a second driver for outputting from said second output path a second partial image produced in said second photoelectric conversion area; a first damper for subjecting the first partial image output from said first output path to a clamp process according to a first clamp level; a second damper for subjecting the second partial image output from said second output path to a clamp process according to a second clamp level; a first setter for setting a black level of the first partial image output from said first output path as the first clamp level; a subtracter for subtracting a difference between a preliminary feeding level of the first partial image output from said first output path and a preliminary feeding level of the second partial image output from said second output path, from the black level of the first partial image output from said first output path; and a second setter for setting the level determined by said subtracter as the second clamp level.
