Abstract: In an image projection system, a computing device generates conversion information for converting camera coordinates used by an imaging device and projector coordinates used by an image projection device based on a positional relationship between a projection pattern image and an imaging pattern image, the imaging device images a subject including a person, the computing device detects a first position indicating a position related to the camera coordinates in a specific region in the person, the computing device converts information on the first position into information on a second position indicating a position related to the projector coordinates in the specific region based on the conversion information, and the image projection device projects a warning image for overlapping with an entire region of the specific region based on the information on the second position.

Abstract: An image display device includes an image input unit into which an image signal from an image signal source is input; a memory; a writing unit that writes at a first frequency an image signal input into the image input unit into the memory; a reading unit that reads at a second frequency higher than the first frequency an image signal written in the memory; an image output unit that outputs an image signal read by the reading unit to a display unit; and an image interpolation unit that interpolates an image to be output to the display unit.

Abstract: A projection system includes an invisible light projector, a background member, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The background member is disposed behind the object in a direction of the invisible light emitted from the invisible light projector. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The background member has a light shielding surface that does not diffusely reflect the invisible light incident thereon.

Abstract: A feature point registration device includes an image filter performing image conversion processing by using a parameter on an input image in which an object appears, a feature point extraction unit extracting a plurality of feature points related to the object from each of different conversion processing images which are the input images after the image conversion processing, an output unit generating a feature point image in which the extracted feature points are superimposed on one of the different conversion processing images, and output a screen including at least the feature point image and an adjustment bar for the parameter to a display device, and an input interface accepting an operation of a user. The output unit updates the feature point image based on the parameter after a change operation by the user on the parameter to the adjustment bar, and outputs the screen to the display device.

Abstract: This fingerprint registration method by a user terminal device includes: capturing an image of a fingertip by a camera provided to the user terminal device; generating and displaying an enlarged image obtained by enlarging a fingertip image that includes the captured fingertip; receiving a user operation whether or not the fingertip image is to be registered for fingerprint authentication on the basis of the enlarged image; and transmitting, to an external server as fingerprint data, the fingertip image on which registration operation has been performed through the user operation.

Abstract: A non-transitory computer-readable storage medium stores a projection adjustment program which, when executed by a processor, causes a computer to execute a process relating to adjustment of projection operations of projection devices configured to perform position measurement and projection on a target object in a projection system including the projection devices. The process includes: causing a first projection device to project invisible measurement light onto the target object; causing a second projection device to receive reflection light reflected from the target object; judging a connection relationship of a projection range of the first projection device on the basis of the received reflection light; executing a process of the judging of the connection relationship on all processing target projection devices; and generating projection position information indicating a connection relationship between projection ranges of the respective projection devices and displaying the projection position information on a display unit.

Abstract: Provided is a real-time-measurement projection device which can measure a distance to a changing target object in real time, and, particularly, can appropriately perform projection and mapping on a changing target object. A real-time-measurement projection device includes a projection device that projects pattern light including a pattern image onto a projection target, an imaging device that electronically acquires a captured image of the projection target irradiated with the pattern light for each pixel for a predetermined exposure time, and a calculation device that calculates a distance to each point of the projection target by contrasting data of the captured image with data of the pattern image, in which the imaging device temporally deviates a start point and an end point of the predetermined exposure time for each pixel.
