A dynamic image display device includes a hardware processor and a display. The hardware processor acquires a first dynamic image captured at a first frame rate and a second dynamic image captured at a second frame rate lower than the first frame rate, and generates an interpolation image between each frame image of the second dynamic image and increases a frame rate of the second dynamic image. The display that displays the first dynamic image and the second dynamic image that includes the interpolation image in a comparable manner.

A synchronized data set is generated from multiple asynchronous data sets. An interpolated data set is generated for each asynchronous data set, at a higher data rate than recorded data rates for the asynchronous data sets. The interpolated data for each data set is then sampled at a lower data rate which is common to all the interpolated data sets. The sampled data points are synchronized between the different data sets, such that the sampled data points represent a synchronized data set. Input telematic data can be reduced to inflection points in the telematic data, and interpolation and sampling of asynchronous data sets can be limited to threshold time periods around the inflection points.

Provided is an XR device using an event camera for divers. The XR device according to an embodiment may generate an external RGB image and an external event image by photographing an external environment, may perform video frame interpolation with respect to the external RGB image by using the external event image, and may display the interpolated external RGB image on a transparent display. Accordingly, clearer underwater images may be provided to divers in a low-light underwater environment in which visibility is significantly reduced due to the refraction of water, blurred vision, turbid water, flow of currents.

An imaging device includes: an imaging element configured to output a sequence of first frames at a first interval through first image capture, and output a second frame through an instruction for second image capture; a thinning unit configured to perform thinning of the sequence of first frames and outputs the thinned first frames at a second interval; and a control unit configured to control an output timing of the second frame on the basis of the first interval or the second interval and an instruction timing for the second image capture.

The present disclosure provides a sequence adjustment method, an apparatus, a computer-readable storage medium, and an electronic device. The sequence adjustment method includes the steps of: upon receiving a data stream output from a DisplayPort transmitter, determining a first line period based on the data stream, where the first line period is a line period of an output clock of the data stream, the output clock being a clock domain of the DisplayPort receiver; processing the first line period using at least a Kalman filter algorithm to obtain a second line period, where the second line period is a line period of a source clock of the data stream, the source clock being a clock domain of the transmitter; and adjusting the output clock based on the second line period. The present disclosure solves the problem in the prior art that image data restored at the DP receiver is distorted and cannot be output normally.

A system for generating motion blur comprises: a frame camera, an event camera and an accumulator for accumulating event information from a plurality of events occurring within a window around the exposure time of an image frame in a plurality of event frames. A processor determines from the events in at least a first of the plurality of event frames, one or more areas of movement within the field of view of the event camera; determines from the events in at least a second of the plurality of event frames, a direction of movement for the one or more areas of movement; and applies blur in one or more areas of the image frame corresponding to the one or more determined areas of movement in accordance with at least the direction of movement for each of the one or more areas of movement to produce a blurred image.

An image processing device includes a memory configured to store instruction thereon; and a processing circuitry configured to execute the instructions. The processing circuitry is configured to execute the instructions to cause the image processing device to divide input video data into a plurality of input video sub-data corresponding to a plurality of sub-areas, generate a plurality of output video sub-data by performing image processing operations on the plurality of input video sub-data, respectively, generate output video data corresponding to the input video data by merging the plurality of output video sub-data. Each of the plurality of input video sub-data includes main input sub-data corresponding to a respective sub-area among the plurality of sub-areas, and boundary input sub-data corresponding to a portion of an adjacent sub-area adjacent to the respective sub-area among the plurality of sub-areas.
