Abstract: An image reading device includes a background unit, a reading unit, and circuitry. The background unit is configured to be a background in reading of a recording medium and includes a first region that is black and a second region that is different from the first region. The reading unit is configured to read an image with the background unit as the background, and generate a read value based on a result of reading the image with the background unit. The circuitry is configured to correct the read value based on a reference value generated by the reading unit by reading the second region of the background unit.

Abstract: An image reading device includes a reader, a first background part, a second background part, and circuitry. The reader reads a pattern formed on a medium. The first and second background parts are disposed opposite the reader via a conveyance passage of the medium. The second background part has a higher light reflectance than that of the first background part. The circuitry moves one of the first and second background parts to a facing position at which the one faces the reader via the conveyance passage of the medium. The circuitry moves the first background part to the facing position in a case in which the pattern is a light color and the medium is transparent. The circuitry moves the second background part to the facing position in a case in which the pattern is a dark color darker than the light color or the medium is not transparent.
