摘要： An image capturing apparatus includes: a casing having an opening; a light source arranged inside the casing; a sensor arranged inside the casing and configured to capture, through the opening, an image of an object present outside the casing while the light source is on; and a distance calculator to calculate a distance between the casing and the object, based on an image that has been captured by the sensor and contains, within an image region of the object defined by the opening, a high-luminance region and low-luminance regions located more outside than the high-luminance region.

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： A distance measuring device includes: an imaging unit that captures a test pattern image including a pair of first markers and a second marker that is formed under a condition different from a condition applied to the first markers; a position detecting unit that detects a position of each of the pair of first markers and the second marker in a captured image captured by the imaging unit; a ratio calculating unit that calculates a ratio of a distance between the pair of the first markers in the captured image and an actual distance between the pair of the first markers; and an actual distance calculating unit that calculates an actual distance between one of the first markers as the pair and the second marker by multiplying a distance between the one of the first markers as the pair and the second marker in the captured image by the ratio.

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.
