INSPECTION APPARATUS

摘要

Provided is an inspection apparatus including a first light receiving unit that receives light from an object where an image is formed based on image data with a first spectral sensitivity characteristic, a second light receiving unit that has a resolution lower than a resolution of the first light receiving unit and receives the light from the object with a second spectral sensitivity characteristic different from the first spectral sensitivity characteristic of the first light receiving unit, and an inspection unit that executes a first inspection for inspecting whether a text or a figure corresponding to the image data is present at a position on the first image and executes a second inspection for inspecting whether halftone dots are formed at a position on the second image.

1. An inspection apparatus comprising:
a first light receiving unit that receives light from an object where an image is formed based on image data with a first spectral sensitivity characteristic; a second light receiving unit that has a resolution lower than a resolution of the first light receiving unit and receives the light from the object with a second spectral sensitivity characteristic different from the first spectral sensitivity characteristic of the first light receiving unit; and an inspection unit that executes a first inspection for inspecting, based on a first image received by the first light receiving unit, whether a text or a figure corresponding to the image data is present at a position on the first image corresponding to a position on the image data where the text or the figure formed by a line is to be present and executes a second inspection for inspecting, based on a second image received by the second light receiving unit, whether halftone dots are formed at a position on the second image corresponding to a position on the image data where color is expressed in a halftone.
