Abstract: An imaging system includes an imaging device, a lighting device, a control part, and an output part. The imaging device images an object. The lighting device irradiates the object with light. The control part controls the lighting device so as to irradiate the object with light from irradiation directions in which directions of irradiating the object with light are different from one another, and causes the imaging device to image the object in each of the mutually different irradiation directions. The output part outputs the plurality of captured images captured by the imaging device to image processing device having a synthesis function of generating a composite image with reduced halation using the plurality of captured images.

Abstract: Appropriate audio processing is selected. A signal processing apparatus includes: an audio signal output unit that outputs a plurality of test sounds in a superimposed manner; a controller that prompts a listener to select a test sound having a specific sense of localization out of the plurality of test sounds; a receiver that acquires results of the selection made by the listener; and an audio signal processing unit that performs audio signal processing associated with the results of the selection on an input signal.

Abstract: A video image in which an inclination angle of a captured video image is changed according to an inclination angle of an operation terminal with which an operator has captured the video image is shared between the operator and an instructor. Provided are a communication unit configured to receive the captured video image, a communication unit configured to acquire a capturing inclination of the captured video image, a corrected video image generation unit configured to change a displayed inclination angle of a received captured video image according to the capturing inclination acquired by the communication unit, and a communication unit configured to output a captured video image, in which the displayed inclination angle has been changed, to an outside.

Abstract: To determine, by image processing, a position at which visual information is to be displayed in a superimposed manner or a position at which visual information is not to be displayed in a superimposed manner. An image processing device (1A) includes a control unit (201) configured to superimpose visual information on an input image, and the control unit (201) determines a position at which the visual information is to be superimposed based on differential information indicating at least one of a difference between pixel values in the input image and a difference between the input images.

Abstract: A designation device designates an object to be photographed by a mobile photographing apparatus that moves in a target section to photograph the object. The designation device includes a display processing unit configured to cause a display to display a map of the target section, and a designation receiver configured to receive a designation of a location corresponding to the object and appearing on the map. The display processing unit superimposes photographing-condition information onto the map on the basis of information about the mobile photographing apparatus to cause the display to display the photographing-condition information. The photographing-condition information indicates a location in which the mobile photographing apparatus is capable of photographing in the target section.

Abstract: A location on a projection surface where visual information is not projected in a suitable manner is detected, and a result of the detection is outputted. A projection suitability detection system (100), which is an aspect of the present disclosure, detects on the basis of a captured image of an operation target object (OB) whether or not the operation target object (OB) has a projection surface that causes projection distortion and then outputs a result of the detection to an instructor (CR) end.

Abstract: In a projection device for projecting content onto a projection medium, a projection area is set up in such a manner as to restrain the visibility of the content from being reduced by the brightness of the projection medium. A projection device for projecting content onto a projection medium detects an illumination intensity distribution on a projection surface of the projection medium and determines a projection area for the content by referring to the illumination intensity distribution.

Abstract: Provided is a technique for projecting appropriate contents in accordance with different places of work. A projection device (101) is provided with a distance acquisition unit (201) configured to acquire the distance between an object and the projection device, a content acquisition unit (203) configured to acquire content information containing a video to be projected and the projection distance of the video, a projection video determination unit (205) configured to refer to the content information acquired by the content acquisition unit in accordance with the distance acquired by the distance acquisition unit and determine the video to be projected, and a projection processing unit (206) configured to project the video determined by the video determination unit on the object.

Abstract: A technique capable of giving instructions efficiently to multiple workers who are in the same space but in different positions is provided. An instruction device (1112) includes a feature point detector (1501), a marker information storage unit (1500), an inter-image transformation parameter calculator (1504), and a marker information transformer (1505). The feature point detector (1501) acquires a first image captured at a first viewpoint and a second image captured at a second viewpoint. The marker information storage unit (1500) acquires first positional information being positional information about a marker superimposed on the first image. The inter-image transformation parameter calculator (1504) makes reference to the first image and the second image and calculates an inter-image transformation parameter for transforming the first image to the second image.

Abstract: To prevent the measurement of the position of a speaker from not being performed in a case where the position of the speaker is changed, and prevent the measurement of the position of the speaker from being performed more than necessary. An AV amplifier (1) according to an aspect of the present invention includes: a control unit (105) that detects a change in the installation position of at least one speaker (2) that supplies an audio signal; and a measurement unit (106) that measures the installation position of at least the speaker (2) of which the installation position is changed among the plurality of speakers (2), automatically or according to a user operation, after the change is detected by the control unit (195).
