1. An image processing device, comprising: a first image acquirer configured to acquire a first image over a first readout time; a second image acquirer configured to acquire a second image over a second readout time, wherein the second readout time is longer than the first readout time; a determiner configured to determine in the first image a location of an object in a portion of the first image that corresponds to a pre-determined part of the second image based on a pre-determined similarity criterion, wherein the pre-determined part of the second image is distorted due to movement of the object during the second readout time; and a copying circuit configured to copy the pre-determined part of the second image to a location in an output image corresponding to the determined location of the object in the first image; wherein the location in the output image is different from the location of the pre-determined part of the second image.
