Abstract: PROBLEM TO BE SOLVED: To obtain an imaging apparatus capable of displaying through-images where no object images overlap even if a photographing lens is not in a focused state while using a pupil division automatic focus.SOLUTION: In a step S901, the amount of the deviation on an imager between an image through a first liquid crystal shutter and an image through a second liquid crystal shutter is calculated. The amount of the deviation is obtained for an image at the center of the imager. In a step S902, an image through the first liquid crystal shutter is moved to the right by a half of the amount of the deviation. Then, an image through the second liquid crystal shutter is moved to the left by a half of the amount of the deviation. In a step S903, the two moved images are added or averaged. Then, in a step S706 of photographing preparation processing, added or averaged images are displayed on an LCD monitor. The addition or averaging is performed for each image pixel.

Abstract: PROBLEM TO BE SOLVED: To obtain an imager capable of achieving focusing by using contrast AF, even in an environment where flicker s are produce.
SOLUTION: In the step S602, whether charge storage time per row, that is, the time elapsed from the timing that an n-th transfer signal line becomes Lo to the timing that it becomes Lo next is smaller than a predetermined threshold is determined. The predetermined threshold is, for example, 50ms so as to include sufficient flicker periodicity, when flicker frequency of a fluorescent lamp is 50 Hz. If the storage time is shorter than that, there is a possibility that received light quantity of a photodiode PD belonging to each row is different by a large amount, in a perpendicular direction. In the step S602, when the charge storage time per row is smaller than the predetermined threshold, processing progresses to the step S603, and contrast AF processing is performed by using a contrast value C obtained from a pixel belonging to a lateral AF area.
