Patent ID: 8488041

Claim:
An image pickup device comprising: an image pickup unit that obtains two picked-up images of a same object with respective optical axis positions being different from each other; a finder image selecting unit that selects either one of the two picked-up images as a finder image; a finder display unit that displays the finder image selected by the finder image selecting unit on a finder screen; a feature detecting unit that detects features of the two picked-up images; an abnormality determining unit that determines whether or not an abnormality is present in one of the two picked-up images based on the features detected by the feature detecting unit; and a warning unit that issues a warning regarding an abnormality when the abnormality determining unit determines that an abnormality is present, wherein the feature detecting unit calculates a brightness dispersion representing a dispersion of brightness values of pixels configuring the picked-up image for each of the two picked-up images, wherein the abnormality determining unit determines whether or not an abnormality is present based on a comparison of respective brightness dispersions between the two picked-up images calculated by the feature detecting unit, and wherein when a difference between the brightness dispersion of the picked-up image selected by the finder image selecting unit and the brightness dispersion of the picked-up image not selected by the finder image selecting unit exceeds a predetermined threshold, the warning unit displays information indicating a region in the picked-up image with a smaller brightness dispersion where an abnormality is present on the finder screen.
