Abstract:
1. A camera device for performing a shooting operation by converting image light into an electrical signal using an image pickup device, the camera device comprising: means for setting detection frames based on a division of an imaging surface of the image pickup device into a plurality of portions; means for detecting the brightness level with every set detection frame; and means for calculating the ratio between the brightness level detected from the detection frame having the lowest detected brightness level and the average value of the brightness levels detected from the detection frames other than the detection frame having the lowest brightness level; and exposure correcting means for performing an exposure correcting operation; said exposure correcting means incorporating at least a function of adjusting a diaphragm and a shutter speed, wherein, when the obtained ratio is equal to or greater than a predetermined value, a backlighted state is determined and a correcting operation is performed only when an adjustment value of the diaphragm and/or the shutter speed at the exposure correcting means is a value which allows determination of whether the shooting environment is outdoors.
