Abstract
There is provided with an image processing apparatus. An acquisition unit acquires, frame by frame, a video to be displayed in a display unit that is obtained by performing rendering processing on each frame of a captured video. An estimation unit estimates an ID of a frame to be acquired by the acquisition unit. A determination unit determines a drop in the frame rate of the video acquired by the acquisition unit, based on a comparison between an ID of a frame acquired by the acquisition unit and the ID estimated by the estimation unit.
Claims20
An image processing apparatus comprising:
- an acquisition unit configured to acquire, frame by frame, a video to be displayed in a display unit that is obtained by performing rendering processing on each frame of a captured video;
- an estimation unit configured to estimate an ID of a frame to be acquired by the acquisition unit;
- and
- a determination unit configured to determine a drop in the frame rate of the video acquired by the acquisition unit, based on a comparison between an ID of a frame acquired by the acquisition unit and the ID estimated by the estimation unit.
An image processing apparatus comprising:
- an image capturing unit configured to capture a video including a plurality of frames;
- an acquisition unit configured to acquire, frame by frame, a video obtained by performing rendering processing on each frame of the captured video;
- a correction unit configured to perform image correction on a frame acquired by the acquisition unit;
- and
- a display unit configured to display a video output from the correction unit,
- wherein a period in which the display unit displays a video is divided into a plurality of subperiods,
- a corresponding input period is prescribed to each of the plurality of subperiods,
- the display unit is further configured to update the frame to be displayed at periodical update timings, and
- the correction unit is further configured to determine whether or not the frame to be displayed in the display unit at a specific update timing has been acquired by the image capturing unit at the input period corresponding to the subperiod that includes the update timing, and perform image correction on a frame to be displayed in the display unit at the specific update timing in accordance with a result of the determination.
An image processing system comprising:
- an image capturing unit configured to capture a video including a plurality of frames;
- an assignment unit configured to assign an ID to each frame of the acquired video;
- an image processing unit configured to output, frame by frame, a video to be displayed in a display unit by performing rendering processing on each frame of the video;
- an estimation unit configured to estimate an ID of a frame to be output from the image processing unit;
- and
- a determination unit configured to determine a drop in frame rate of the video output from the image processing unit, based on comparison between the ID of a frame output from the image processing unit and the ID estimated by the estimation unit.
An image processing method comprising:
- acquiring, frame by frame, a video to be displayed in a display unit that is obtained by performing rendering processing on each frame of a captured video;
- estimating an ID of a frame to be acquired;
- and
- determining a drop in the frame rate of the acquired video, based on a comparison between an ID of an acquired frame and the estimated ID.
A non-transitory computer-readable medium storing a program which, when executed by a computer comprising a processor and a memory, causes the computer to perform a method comprising:
- acquiring, frame by frame, a video to be displayed in a display unit that is obtained by performing rendering processing on each frame of a captured video;
- estimating an ID of a frame to be acquired;
- and
- determining a drop in the frame rate of the acquired video, based on a comparison between an ID of an acquired frame and the estimated ID.
