摘要： A nozzle testing device includes: a two-dimensional image sensor to capture an image of a pattern formed on a recording object by discharging ink from a nozzle row while moving the nozzle row and the recording object relative to each other in a direction orthogonal to the nozzle row; a light source unit provided such that regularly reflected light by the pattern forms a regular reflection area in the image of the pattern captured by the two-dimensional image sensor; and a detection unit to analyze the image to detect discharge failure of the nozzles. The regular reflection area is formed in the image such that a dimension in a direction corresponding to the direction of relative movement between the nozzle row and the recording object is greater than a dimension in a direction orthogonal to the direction corresponding to the direction of relative movement in the image.

摘要： An imaging device including a light source; a two-dimensional image sensor that receives reflected light from a subject containing specular light of the light source and outputs an image of the subject; a light transmission member disposed in an optical path of light emitted from the light source to the subject; and a light shielding unit that, when a position on the subject at which light from the light source is regularly reflected and enters the two-dimensional image sensor is defined as a first specular position, whereas a position on the light transmission member at which light from the light source is regularly reflected and enters the two-dimensional image sensor is defined as a second specular position, shields the light directed from the light source toward the second specular position without shielding the light directed from the light source toward the first specular position.

摘要： An image capturing device includes: a two-dimensional image sensor that captures an image of a predetermined image capture area including a subject; a light source that illuminates the image capture area; and a light blocking member that blocks light traveling from the light source toward a specular reflection position, the specular reflection position being a position that is in the image capture area and where, if light travels from the light source, the light would be specularly reflected to the two-dimensional sensor. The light blocking member is arranged outside the image capture area.
