摘要： An apparatus includes: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the source to the subject. When a specular position of the source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the source toward the first specular position and an incident angle from the source toward the second specular position is a reference value or more.

摘要： A medium identification device identifies a type of a recording medium used for image formation. The medium identification device includes: a two-dimensional image sensor that captures an image of the recording medium; and an identifying unit that obtains a glossiness evaluation value indicating glossiness of the recording medium, a surface roughness evaluation value indicating surface roughness of the recording medium, and a coloring evaluation value indicating coloring of the recording medium, using image data of a specular reflection region reflecting specular reflection light from the recording medium and image data of a diffused reflection region reflecting diffused reflection light from the recording medium, the regions being in the image of the recording medium, and identifies the type of the recording medium by combining determination using the glossiness evaluation value, determination using the surface roughness evaluation value, and determination using the coloring evaluation value.

摘要： A liquid discharge apparatus includes a liquid discharge head, a scanning device, a conveyance device, a reading device, control circuitry, and a detecting device. The liquid discharge head is configured to discharge liquid to a target object. The scanning device is configured to move the liquid discharge head in a main scanning direction. The conveyance device is configured to convey the target object in a direction perpendicular to the main scanning direction. The reading device is disposed at a predetermined position with respect to the liquid discharge head. The control circuitry is configured to change a detection pattern image for detecting a defective nozzle, in accordance with a feed amount of the target object in the sub-scanning direction. The detecting device is configured to identify a nozzle corresponding to a defective portion of the detection pattern image read by the reading device.
