An image processing device includes an evaluation value calculation section (321), an estimated noise amount acquisition section (322), a determination section (324), and a noise reduction processing section (325). The evaluation value calculation section (321) calculates an evaluation value that is used to determine whether or not an inter-frame state of an object within a captured image is a stationary state. The estimated noise amount acquisition section (322) acquires an estimated noise amount of the captured image. The determination section (324) determines whether or not the inter-frame state of the object is the stationary state based on the evaluation value and the estimated noise amount. The noise reduction processing section (325) performs a first noise reduction process (time-direction noise reduction process) on the captured image when it has been determined that the inter-frame state of the object is the stationary state, and performs a second noise reduction process that includes at least a spatial-direction noise reduction process on the captured image when it has been determined that the inter-frame state of the object is not the stationary state. |
