The spectrophotometer CI is mounted on and fixed to the support base TR, and spaced from the paper transfer route PP by a predetermined distance.

The disclosure provides a device for recognizing an image and a device for reading an image. The device for recognizing the image includes a circuit board (50) on which a plurality of light sources (20) are arranged, the multiple light sources (20) which are configured to supply multiple lights in different directions to the image to be recognized, and an imaging component configured to uniformly image the lights diffused by the image to be recognized so as to recognize the image to be recognized. The disclosure solves the problem that the device for recognizing the image in the relevant technology may only supply one single light emitting direction, and the device for recognizing the image has a beneficial effect of recognizing a hologram including various pieces of image information.

Provided is an image reading apparatus, including: a reader comprising a light source upstream of an image reading position and a light source downstream of the image reading position in a moving direction, each light sources sequentially irradiating an original with light of different colors, the reader reading an original image at the image reading position while moving each light sources relatively to the original in the moving direction; a controller controlling the reading of the original image by the reader by setting a light amount ratio of the light source arranged on the upstream side to the light source arranged on the downstream side for a particular color of the different colors to be different from a light amount ratio for another color; and a detector detecting an image pattern of the particular color depending on the light amount ratio from the original image read by the reader.

Provided is an image reading apparatus including a line sensor including three line sensors arranged at a predetermined interval in a sub-scanning direction, and being configured to read an image of an original by the respective line sensors, which includes light receiving elements arranged in a first direction, to generate read data representing the read image, the three line sensors each including a first light receiving element configured to receive red light, a second light receiving element configured to receive blue light, and a third light receiving element configured to receive green light, which are arranged in a main scanning direction; and a reading control board. The reading control board is configured to generate a first combined flag obtained by combining results of detecting abnormal images of respective colors and a second combined flag obtained by combining results of detecting abnormal images of the respective colors.

A controlling apparatus has a receiving unit receiving a print job, a determination unit determining whether there is a difference in a conveying mechanism based on settings of a first print job received by the receiving unit and settings of a second print job executed before the first print job; and an execution unit executing an inspection process based on a result of reading by an image reading unit in a case where the determination unit determines that there is a difference in the conveying mechanism.

An image processing portion of an image reading apparatus includes an extraction portion that extracts color information, a management portion that manages management color information that is an estimated value of the color information based on a control signal, a determination portion that determines whether or not the color information matches the management color information, and a writing control portion that causes the storage portion to store the pixel data when it is determined that the color information matches the management color information and that does not cause the storage portion to store the pixel data when it is determined that the color information does not match the management color information.
