Abstract
A detection device, including a first displacement acquisition unit configured to compare an image of an m-th block included in a first frame captured by an area image sensor using a rolling method with an image captured in the m-th block included in a second frame captured after the first frame to acquire displacement of the image with respect to a main scanning direction of the line, a second displacement acquisition unit configured to compare an image of a p-th block included in the first frame with an image captured in the p-th block included in the second frame to acquire displacement of the image with respect to the main scanning direction, and a difference acquisition unit configured to acquire, as a value corresponding to acceleration of the area image sensor, difference between the displacement acquired in the m-th block and the displacement acquired in the p-th block.
