Abstract

A spectral-characteristic acquisition apparatus (10) and a method of obtaining spectral characteristics. The spectral-characteristic acquisition apparatus (10) includes a conveyor (30, 31, 32) including a first conveyance roller pair disposed in a conveyance direction in which an object (100) is conveyed and a second conveyance roller pair disposed downstream from the first conveyance roller pair in the conveyance direction, a sensor (42) configured to detect that the object (100) has reached the second conveyance roller pair, a controller (300) configured to control the second conveyance roller pair to drive by a predetermined amount with a driving force greater than a driving force of the first conveyance roller pair upon detecting that the object (100) has reached the second conveyance roller pair by the sensor (42), and to stop driving, a color data obtainer (20) configured to obtain color data from the object (100) at a position where the object (100) stops moving, and a spectral-characteristic computing unit (113) configured to estimate a spectral characteristic of the object (100) based on the color data obtained by the color data obtainer (20).
