An iris image acquisition system for expanding an iris recognition range is proposed. The iris image acquisition system for expanding the iris recognition range enables that a direction, zoom, and focusing of an iris photographing camera for photographing an iris image of a distant subject are controlled quickly and easily without high-level information processing and arithmetic processing.

Provided is a method of setting a scan region, the method including: placing a target object on an upper surface of a jig of a three-dimensional scanner in such a manner that at least one portion of a target object image representing a shape of the target object is plotted on an input region; determining, by a control unit, a predetermined upper portion of the input region, as a scan region, from a jig image representing the shape of the jig; and generating, by the control unit, a three-dimensional model of the target object on the basis of the target object image resulting from scanning the scan region.

In one example, a system for evaluating an agricultural material is provided. The system comprising: a housing having a passage in or through an interior of the housing with an inlet for receiving agricultural material and an outlet for outputting the agricultural material; a wall opening in a wall of the passage; and an imaging device having a window located within a border, the imaging device having a removable portion with at least one of a moisture absorbing material, a heat source, and an anti-fog agent within the removable portion.

An imaging apparatus includes: a face detection sensor configured to detect a face of a user; a control unit configured to change an operational state of the imaging apparatus to a first operational state and stop an operation of the face detection sensor; and a movement detecting unit configured to detect a movement of the imaging apparatus, wherein the control unit operates the face detection sensor in response to a detection of a movement of the imaging apparatus by the movement detecting unit in the first operational state, and in a case where the face of the user is not detected by the face detection sensor in the first operational state, the control unit changes the operational state of the imaging apparatus from the first operational state to a second operational state in which power consumption is lower than that in the first operational state.

There is provided a monitoring device that monitors another person's peeping into a document to be read, a medium on which drawing output is performed, or content displayed by an image processing apparatus, and the monitoring device includes a first hardware processor that: acquires person information indicating a person present within a predetermined range from the image processing apparatus; performs determination including whether or not a person other than the operator among persons identified by the person information acquired is a person having a predetermined relationship with the operator; and performs control to cause warning information to be output in a case where it is determined that there is at least one person not having the predetermined relationship among the persons identified, and performs control to cause output of the warning information to be prevented in a case where it is determined that all the persons have the predetermined relationship.
