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: This biological information acquisition device comprises: a first camera which captures a first hand image of a user, the hand being inserted into an imaging region; a second camera which captures a second hand image of the user used for biological authentication; and a processor which causes the second camera to capture the second hand image when a stop of the user's hand is detected on the basis of the hand image captured by the first camera.

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: There is provided is a method for enhancing a video image capable of achieving high image quality improvement for both a texture area and an edge area. A maximum limit value and a minimum limit value of a video signal value enhanced on the basis of a pixel signal value in an area set around the target pixel are calculated, the maximum limit value and the minimum limit value are corrected according to a texture value calculated as a scale value that indicates a variation of the pixel signal value in the corresponding area, and the corrected maximum limit value and minimum limit value are applied to the enhanced video signal value.

Abstract: Projection device switches and projects a plurality of types of pattern images in a unit of projection frame. Imaging device images object to which the pattern image is projected and generates image data. Measurement device discriminates whether each imaging frame is a key frame of the image data obtained by capturing one of the pattern images or a blended frame of the image data obtained by capturing a plurality of the pattern images switched during an exposure period of one frame, and performs measurement based on a space coding method by using at least the image data of the key frame.

Abstract: An image projection system includes an infrared ray projection apparatus that projects a pattern image for shape measurement toward a projection target, an imaging device that captures the pattern image, a calculation device that acquires three-dimensional shape information of the projection target based on the captured pattern image and converts a content image into a projection content image corresponding to the projection target based on the three-dimensional shape information, and a visible light projection apparatus that is disposed in a different position from the infrared ray projection apparatus and projects the projection content image toward the projection target, in which the calculation device, based on images of a visible light image projected by the visible light projection apparatus and a non-visible light image projected by the infrared ray projection apparatus, executes processing of associating each pixel of the non-visible light image with each pixel of the visible light image.

Abstract: A projection control device includes: a communication unit connected to communicate with an image capturing device configured to capture an image of a target object positioned around a projected object; a derivation unit configured to derive a projection position of a content image based on designation of a parameter related to the content image to be projected onto the projected object and an image of the projected object including the target object; a projection image generation unit configured to generate a projection image including the content image disposed at the derived projection position; and a control unit configured to transmit a projection instruction of the projection image to a projection device via the communication unit.
