Abstract

A video frame processing method, which comprises: (a) capturing at least one first video flame via a first camera; (b) capturing at least one second video frame via a second camera; and (c) adjusting one candidate second video frame of the second video frames based on one of the first video frame to generate a target single view video frame.

Claims (26)

1 . A video frame processing method, comprising:

(a) capturing at least one first video frame via a first camera utilizing a first camera parameter;

(b) capturing at least one second video frame via a second camera utilizing a second camera parameter, wherein the second camera parameter is different from the first camera parameter; and

(c) generating a target single view video frame corresponding to a specific time point according to the at least one first video frame, the first camera parameter and the second camera parameter.

2 . The video frame processing method of claim 1 , wherein the step (c) comprises:

determining if the first video frame corresponding to the specific time point exists;

if yes, selecting the first video frame as the target single view video frame; and

if not, interpolating the target single view video frame according to one of the second video frames corresponding to the specific time point and one or more adjacent frames captured by the first camera and/or the second camera.

3 . The video frame processing method of claim 2 , wherein the first camera parameter and the second camera parameter are video frame resolutions, wherein the first camera parameter is higher than the second camera parameter, and a video frame rate of the first camera is identical to or lower than a video frame rate of the second camera.

4 . The video frame processing method of claim 2 , wherein the first camera parameter and the second camera parameter are video frame rates, wherein the first camera has a video frame rate lower than which of the first cameras.

5 . The video frame processing method of claim 1 , wherein the step (c) generates the target single view video frame further according to one of the second video frames.

6 . The video frame processing method of claim 5 , wherein the step (c) interpolates the target single view video frame from the first video frame corresponding to the specific time point and the one of the second video frames.

7 . The video frame processing method of claim 5 , wherein the first camera parameter and the second camera parameter are video frame capturing parameters, and the step (c) generates the target single view video frame according to, video &aim capturing parameters for the first video frame corresponding to the specific time point and the one of the second video frames.

8 . The video frame processing method of claim 7 , wherein the frame capturing parameter comprises at least one of: capturing time, exposure time, depth of field, focus, ISO speed, and white balance.

9 . The video frame processing method of claim 1 , wherein the step (c) generates the target single view video frame further according to at least one adjacent frames captured by the first camera and or the second camera.

10 . The video frame processing method of claim 1 , wherein the first camera parameter and the second camera parameter are video frame rates, wherein the first camera has a video frame rate higher than which of the second camera.

11 . The video frame processing method of claim 10 , wherein the target single view video frame has an image resolution higher than which of the first video frame.

12 . The video frame processing method of claim 1 , wherein the first camera parameter and the second camera parameter are a exposure time and/or an ISO speed, wherein the step (c) comprises:

determining at least one region to be enhanced in the first video frame corresponding to the specific time point according to the first camera parameter;

determining at least one region to be referenced in the second video frame corresponding to the specific time point according to the second camera parameter; and

enhancing the at least one region to be enhanced in the first video frame based on the at least one region to be referenced in the second video frame.

13 . The video frame processing method of claim 1 , wherein the target single view video frame further corresponds to a viewing perspective of the first video frame, wherein generating the target video frame comprising:

selecting the first video frame as the target single view video frame when image quality of the first video frame is better than a quality threshold; and

generating the target single view video frame by adjusting the first video frame or the second video frame when the image quality of the first video frame is not better than the quality threshold, including:

interpolating the first video frame and another video frame captured via the first camera to generate a third video frame, and

adjusting the second video frame based the third frame to generate the target single view video frame.
