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: 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: 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: A biometric information acquisition device includes a housing. The housing includes a bottom surface side, a top surface side, a front surface side, a back surface side, and an opening in the front surface side between the bottom and top surface sides. The opening defines an imaging space. A camera is disposed in the housing, with the camera being configured to capture an image of a palm of a hand of a user when inserted into the imaging space with the palm facing the top surface side. An illumination is between the top surface side and the opening, with the illumination being configured to illuminate the imaging space from above. A mirror reflects light from the illumination toward the palm, and a display prompts the user to insert the palm into the imaging space with the palm facing the top surface side.

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: 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 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.
