A display system includes a plurality of display devices each of which includes circuitry. The circuitry of each of the plurality of display devices synchronizes a reproduction time with other of the plurality of display devices. The reproduction time is a time to reproduce content including an image and audio. The circuitry further starts displaying the image at a predetermined time and starts outputting the audio at the predetermined time. In response to detection of one of a failure and a probability of failure to output the audio at the predetermined time, the circuitry further stops outputting the audio.

Display device, display system, and non-transitory recording medium, to adjust position of second image in accordance with adjusted zoom ratio of first image

A video playback system includes a first acquirer configured to acquire first specification information indicating video playback performance of an image display device; a second acquirer configured to acquire second specification information indicating video creating performance of an image supply device; a determiner configured to determine, based on the first specification information and the second specification information, either the image display device or the image supply device to be a device satisfying a playback condition; and a controller configured to, when the playback condition is changed to a new playback condition while the image display device is playing a video, cause the converter of the image display device to convert the video data into video data satisfying the new playback condition until the image display device receives video data where the new playback condition is reflected from the image supply device.

Video playback system and image display device

A measurement device includes an image capturing unit which includes a photoelectric unit and captures multiple images corresponding to different photoelectric areas of the photoelectric unit, multiple reflecting units arranged at different positions and configured to reflect light traveling from a projection area, changing units which change image capture angles of the reflecting units, a light condensing unit which condenses the light reflected off the different reflecting units to the different photoelectric areas, an obtaining unit which obtains the captured images corresponding to the photoelectric areas and corresponding image capture angles of the reflecting units, a selection unit which selects, from the captured images, two or more images in each of which a measurement subject is captured, and a calculation unit which calculates a position of the measurement subject in a 3D space from the selected captured images and the image capture angles corresponding to the captured images.

Measurement method, measurement device, projection apparatus, and computer-readable recording medium

An image processing device provides a detection result of additional information added to each of pages which constitute a document. The image processing device includes an input part which inputs image data of each page of a document. A detection part generates a page detection result of additional information added to the image data, the page detection result being generated on a page basis and indicating a result of detection of the additional information for each page. A detection result output part outputs an outline result indicating an outline of the page detection results for the respective pages on a document basis, together with an identifier of the document associated with the outline result.

Image processing device, additional information providing method, and computer-readable storage medium

An image processing apparatus includes an obtaining unit, an area setting unit, and an adding unit. The obtaining unit obtains an adding method by which additional information is to be added to image data containing content information. The area setting unit sets an additional-information area to which the additional information is to be added based on the adding method and the content information. The adding unit adds the additional information to the additional-information area by the adding method.
