The present invention relates to an error correction unit for a time slice image. The present invention comprises: a stand having a length corresponding to the height of an object and standing upright; and a plurality of marker members, installed on the stand, for indicating a plurality of reference positions for setting an offset reference value, and providing the same shape in all directions. The present invention can readily set the offset reference value through the plurality of reference positions.

The present technology relates to a video processing device, a video processing method, and a program for providing a bullet time video centering on a moving object. The video processing device acquires view point position information indicating the range of movement of a view point position for an object in an input image frame where the object is imaged in chronological order at multiple different view point positions. Time information indicates a time range in the chronological order of imaging the input image frame. The device processes the input image frame such that the object is at a specific position on an output image frame when the view point position moves within the time range indicated by the time information and the view point position movement range indicated by the view point position information.

An image capturing system introduces or controls an aliasing/stroboscopic effect in a cyclically moving object. The system has a camera to capture a series of images to form a video of the cyclically moving object. A sensor detects the cycling frequency of the cyclically moving object and generates a frequency reading with a control module communicably coupled to the sensor. Retro-reflective indicia are provided on the cyclically moving object. A light emitter is aligned with the camera and is operable to emit pulses of light at a controllable emission frequency, such that pulses of light which reach the retro-reflective indicia are reflected backwards towards the camera, wherein the control module is configured to control the emission frequency of the light emitter based on the frequency reading, thereby to influence the temporal aliasing of the retro-reflective indicia provided on the cyclically moving object.

A device for processing a stream of video data which comprises a sequence of frames comprises an interface configured to receive the stream of video data. A processing device is configured to create a three-dimensional environment from a frame of the sequence of frames when a freeze condition is detected. The processing device is configured to generate a series of frames from the three-dimensional environment. The series of frames represents the three-dimensional environment from a plurality of points of view. The processing device is configured to insert the generated series of frames into the sequence of frames to generate a modified sequence of frames to conceal a freeze.

Data comprising a compressed image frame and temporal redundancy information is received. The image frame is decompressed. A plurality of bridge frames that are visually dissimilar to the image frame are generated. The image frame and the plurality of bridge frames are blended, generating a plurality of blended frames, and the plurality of blended frames are displayed.

An exercise evaluating apparatus including: a processor; and a recording medium which records a program executed by the processor to perform processing, wherein, the processor is configured to perform: generating a combined image from a plurality of images successively imaging a moving subject, the combined image being an image in which a change in motion of the subject according to a time series can be understood; obtaining motion data corresponding to motion of the subject output from a motion sensor attached to the subject; and controlling the display to display the combined image and the motion data in a state corresponding a time series of the plurality of images used in generating the combined image with a time series of the obtained motion data.

In a method of displaying a representation of a virtual background by means of a background display device for a recording by a camera in a virtual image recording studio, the display of the representation of the virtual background takes place in accordance with a time control. The camera further records the display of the representation of the virtual background in accordance with a sequence of exposure times and the time control of the display of the representation of the virtual background and the sequence of exposure times are synchronized with one another.

A virtual flying camera system is disclosed. According to one embodiment, the virtual flying camera system includes a plurality of cameras disposed along a track and spaced apart from each other, a recording system configured to receive input video streams from the plurality of cameras, and a control system configured to generate an output video stream from the input video streams. The output video stream includes a view of a virtually flying camera following a target at a user-adjustable speed. The control system generates the output video stream by merging a plurality of portions of the input video streams from adjacent cameras of the plurality of cameras.

Apparatus and methods for displaying an image by a rotating structure are provided. The rotating structure can comprise blades of a fan. The fan can be a cooling fan for an electronics device such as an augmented reality display. In some embodiments, the rotating structure comprises light sources that emit light to generate the image. The light sources can comprise light-field emitters. In other embodiments, the rotating structure is illuminated by an external (e.g., non-rotating) light source.
