Abstract

A detection apparatus includes the following elements. A first measuring unit measures, from a binary image, density levels of first and second regions which are alternately arranged in a first direction in the binary image, the binary image being disposed on a second surface of a holding member which includes a first surface and the second surface. A storage unit stores therein information indicating an association between a distance from the first measuring unit to the second surface and a contrast between the adjacent first and second regions. A calculator calculates a contrast between the adjacent first and second regions. A detector specifies a distance corresponding to the calculated contrast by using the stored information, and detects a deflection of the holding member in the first direction by using the specified distance as the distance from the second surface to the adjacent first and second regions.
