A defective pixel detecting device determining defective pixels as correction targets in an imaging device that produces image signals is provided, and the device includes: defect information storage configured to store priority of defective pixels to be corrected; a defective pixel detector configured to detect defective pixels by comparing levels of imaging signals from the imaging device with a predetermined detection level; a priority setter configured to set priority of the detected defective pixels, based on the levels of the imaging signals of the defective pixels detected by the defective pixel detector; and a correction target determiner configured to newly determine defective pixels to be corrected based on the priority of the defective pixels out of the defective pixels that are currently detected by the defective pixel detector and the defective pixels to be corrected stored in the defect information storage, determining priority of the newly determined defective pixels to be corrected, and storing the priority of the newly determined defective pixels to be corrected in the defect information storage.
