US 2018/0007249 A1 · IMAGE PICKUP APPARATUS CALCULATING LIGHT-AMOUNT VARIATION CHARACTERISTIC OF LIGHT FROM OBJECT, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR

Abstract

An image pickup apparatus capable of improving accuracy of calculation of a light-amount variation characteristic of light from an object when displaying a through image. A control unit picks up a first image with an image pickup device according to an image pickup condition changed when the image pickup condition is changed from a predetermined condition while displaying the through image, picks up a second image with the image pickup device within a first accumulation period without reflecting the image pickup condition changed, and picks up a third image with the image pickup device within a second accumulation period shorter than the first accumulation period without reflecting the image pickup condition changed. A display control unit displays the first image on a display unit as the through image. A calculation unit calculates the light-amount variation characteristic of light from an object based on the second and third images.
