Method and apparatus for estimating the depth of focused plenoptic data are suggested. The method includes: estimating the inherent shift of in-focus pixels of the focused plenoptic data; calculating a level of homogeneity of the pixels of the focused plenoptic data; determining the pixels of the focused plenoptic data which either have disparities equal to the inherent shift or belong to homogeneous areas, as a function of the level of homogeneity of the pixels of the focused plenoptic data; and estimating the depth of the focused plenoptic data by a disparity estimation without considering the determined pixels. According to the disclosure, the pixels of the focused plenoptic data which either have a disparity equal to the inherent shift or belong to a homogeneous area will not be considered for the estimation of the depth, which can reduce computational costs and at the same time increase accuracy of estimations for in-focus parts of the scene.

An image processing system receives a sequence of frames including a current input frame and a next input frame (the next input frame is captured subsequent in time with respect to capturing of the current input frame). The image processing system stores a previously outputted output frame. The previously outputted output frame is derived from previously processed input frames in the sequence. The image processing modifies the current input frame based on detected first motion and second motion. The first motion is detected based on an analysis of the current input frame with respect to the next input frame. The second motion is detected based on an analysis of the current input frame with respect to the previously outputted output frame. According to one configuration, the image processing system implements multi-sized analyzer windows to more precisely detect the first motion and second motion.

A system is described for maintaining synchrony of operations among a plurality of devices that have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.

A display system includes a conversion apparatus converting video luminance including a luminance value in a first luminance range and a display apparatus connected thereto and displaying the video. The conversion apparatus includes a first acquisition unit, a first luminance converter, a second luminance converter, a quantization converter, and an output unit outputting a third luminance signal to the display apparatus. The display apparatus includes: a second acquisition unit acquiring the third luminance signal and setting information indicating display settings recommended to the display apparatus in display of the video; a display setting unit setting the display apparatus, using the setting information; a third luminance converter converting a third code value indicated by the third luminance signal into a second luminance value compatible with a second luminance range, using the setting information; and a display controller displaying the video on the display apparatus based on the second luminance value.

A video processing device connectable with a recorder includes a first receiver and a controller. The first receiver receives a main video signal containing two or more frames which are consecutive in time sequence, the main video signal produced by imaging two or more subjects including at least one moving subject. The controller generates one or more sub video signals produced by imaging a first subject of the plurality of subjects, from the main video signal. The controller generates main video data including the main video signal and first association information specifying the one or more sub video signals generated from the main video signal. Furthermore, the controller generates one or more sub video data including the one or more sub video signals and second association information specifying the main video signal from which the one or more sub video signals have been generated. The controller makes a recorder store the main video data and the one or more sub video data.
