Should be understood that, this static object for as if for rotation, instead of other motion, if a destination object of coming up towards electronic equipment is a static object object at this, and the blade of the windmill rotated is not just static object object.
In a particular embodiment of the present invention, need to control to make the destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold, in a particular embodiment of the present invention, can be realized by two kinds of modes, be respectively described below.
< mode one >
In mode one, to composition video file frame of video more rotational case carry out rotations process.
In mode one, described when the described current direction of described judged result instruction changes relative to described reference direction, perform an acquisition process operation and specifically comprise:
The original video frame that the data that acquisition image acquisition units collects obtain;
When the described current direction of described judged result instruction changes relative to described reference direction, by described original video frame at execution rotation process, obtain target video frame, otherwise direct described original video frame is as target video frame;
Wherein, all target video frames forming described video file when playing, the destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold.
In mode one, when the described current direction of described judged result instruction changes relative to described reference direction, by described original video frame at execution rotation process, obtain target video frame, otherwise direct described original video frame is as target video frame, the all target video frames forming described video file when playing, the destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold.Owing to forming all target video frames of described video file in all frame of video when playing, destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold, so in the playing process of whole video file, this destination object can not exceed the rotation of pre-determined threshold relative to display frame, user can conveniently be watched.
< mode two >
In mode one, rotate process in advance to the frame of video of composition video file to ensure that the change of the destination object in display frame relative to the display direction of display frame is lower than pre-determined threshold, this is the process at file formation stages, but the destination object in guarantee display frame also can realize in the broadcasting stage lower than pre-determined threshold relative to the change of the display direction of display frame, but need the rotation information in the pre-recorded frame of video of the formation stages of video file, the rotation information that player can be more pre-recorded is made to carry out rotation process to frame of video, ensure in video file playing process, destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold, be described in detail as follows.
In mode two, described when the described current direction of described judged result instruction changes relative to described reference direction, perform an acquisition process operation and specifically comprise:
The original video frame that the data that acquisition image acquisition units collects obtain;
When the described current direction of described judged result instruction changes relative to described reference direction, record the rotation information that described original video frame is corresponding, make playout software after receiving described original video frame, according to described rotation information, described original video frame is performed rotation process, play after obtaining target video frame, ensure that all target video frames of the described video file of composition are when playing, the destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold.
In mode two, by the rotation information that pre-recorded described original video frame is corresponding, make playout software according to described rotation information, original video frame can be performed rotation process, ensure that the change of the destination object in display frame relative to the display direction of display frame is lower than pre-determined threshold.
For the record of this rotation information, can realize in several ways, as:
Correspond to separately this original video files and generate a rotary information recording file, wherein record the corresponding relation of rotation information and frame of video sequence number, playout software is when processing each two field picture, from this log file, search whether there is corresponding rotation information according to frame number, if had, then carry out rotation process according to rotation information, otherwise carry out operating according to existing method.
Certainly, the field of a record rotation information can also be increased in the form of existing frame of video, playout software decode time according to record rotation information field whether be that sky carries out subsequent operation, when the field recording rotation information is not empty, then extract and carry out rotation process according to rotation information, otherwise carrying out operating according to existing method.
Certainly, how to record this rotation information and how playout software obtains this rotation information, completely can adopt alternate manner to realize, as long as which can be played software simulating, be not limited to above implementation.
In a particular embodiment of the present invention, no matter be in front-end processing (in the process of generating video file), or back-end processing (playout software process), all need to perform a rotation process to frame of video, the anglec of rotation of this rotation process and the determination of direction of rotation can be that various ways is to ensure that the change of the destination object in display frame relative to the display direction of display frame is lower than pre-determined threshold.
Destination object in < display frame maintains consistent > relative to the display direction of display frame
In a particular embodiment of the present invention, destination object in display frame relative to the change of the display direction of display frame lower than pre-determined threshold, in implementation one, be ensure that the destination object in display frame remains unchanged relative to the display direction of display frame.
Under this implementation, describedly judge whether the current direction of described electronic equipment changes relative to a reference direction according to described directioin parameter, obtain a judged result and be specially:
The current direction calculating described electronic equipment according to described directioin parameter is relative to the anglec of rotation of described reference direction and direction of rotation; When the described anglec of rotation is greater than 0, the described current direction of described judged result instruction changes relative to described reference direction, otherwise indicates described current direction not change relative to described reference direction;
And when the described current direction of described judged result instruction changes relative to described reference direction, described original video frame is performed rotation process and is specially:
Described original video frame is rotated up the described anglec of rotation in the side contrary with described direction of rotation.
In above-mentioned mode, when obtaining each two field picture, all judge that the current direction of electronic equipment is relative to the anglec of rotation of described reference direction and direction of rotation, when the anglec of rotation is greater than 0, then represent that current direction changes relative to described reference direction, now, need to rotate in the opposite direction the current frame of video obtained, rotate the impact brought with counteracting equipment, illustrate as follows.
Assuming that when collection the n-th frame, electronic equipment have rotated 35 degree relative to reference direction clockwise, be then that described original video frame inverse clock is rotated 35 to the rotation process of original video frame.
Assuming that when collection the (n+1)th frame, electronic equipment have rotated 55 degree relative to reference direction clockwise, be then that described original video frame inverse clock is rotated 55 to the rotation process of original video frame.
Destination object in < display frame is relative to display direction > in the predetermined interval being greater than 0 of display frame
In the second way, ensure that the destination object in display frame is greater than in the interval of 0 in predetermined relative to the display direction of display frame.
Under this mode, arrange certain interval, the rotation in a certain interval is all converted into and rotates identical angle, under this mode, describedly judge whether the current direction of described electronic equipment changes relative to a reference direction according to described directioin parameter, obtain a judged result and be specially:
The current direction calculating described electronic equipment according to described directioin parameter is relative to the anglec of rotation of described reference direction and direction of rotation; When the described anglec of rotation is greater than 0, the described current direction of described judged result instruction changes relative to described reference direction, otherwise indicates described current direction not change relative to described reference direction;
Described rotation process is specially:
By described original video frame anglec of rotation described in rotation process on the direction contrary with described direction of rotation.
In aforesaid way, when electronic equipment is less relative to the rotation of reference direction, can not cause follow-up follow-uply carry out rotation process to frame of video or recording rotation information corresponding to described original video frame, save processor resource, illustrated as follows to the realization of this mode.
Assuming that pre-set following corresponding relation:
Anglec of rotation section space aim angle
Be greater than 0, and be less than or equal to 300
Be greater than 30, and be less than or equal to 6030
Be greater than 60, and be less than or equal to 9060
............
When user takes, if the anglec of rotation is greater than 0, the described current direction of now judged result instruction changes relative to described reference direction, now can according to the corresponding relation between pre-recorded anglec of rotation interval and angle on target, determine the interval corresponding first object angle of first anglec of rotation at described anglec of rotation place, and follow-up, described original video frame is rotated up described first object angle in the side contrary with described direction of rotation, or record the rotation information that described original video frame is corresponding, follow-uply to be controlled by playout software.
Illustrate as follows, when electronic equipment is less than or equal to 30 degree relative to the reference direction anglec of rotation, now can not carry out any other process, but when electronic equipment rotates 45 degree relative to reference direction clockwise, now described original video frame can be rotated 60 degree at inverse clock.
For above-mentioned example, the destination object in display frame can not more than 30 degree relative to the change of the display direction of display frame, and therefore user need not significantly adjust viewing posture.
Certainly, only to illustrate above, in order to reduce the amplitude of variation of display direction, can arrange every 15 degree of intervals, this depends on the actual demand of user.
Mention before, when causing video file to play, reference object is that electronic equipment rotates relative to the reason that display frame rotates, therefore the impact brought to eliminate/reducing this rotation just needs the rotational case of recorded electronic equipment, but the rotation of recorded electronic equipment needs a reference direction, to compare the current direction of electronic equipment and reference direction, determine whether carrying out acquisition process operation and how carrying out acquisition process operation, in a particular embodiment of the present invention, this reference direction can be an absolute direction changed never, also can be a relative direction changed with different situations, be respectively described below.
< reference direction is gravity direction >
Consider that electronic equipment rotation can cause one to be originally in static object rotational display in different frame of video, if and need the destination object maintaining this static state to remain unchanged relative to the display direction of described display frame, destination object in all frame of video is then needed to remain unchanged relative to the display direction of display frame, and the acquisition process operation realizing this object needs the rotational case considering electronic equipment, in implementation one, gravity direction is set to reference direction, follow-uply carry out respective handling based on the current direction of electronic equipment relative to the change of gravity direction, concrete processing procedure will be described in detail later.
This function of gravity sensing has obtained actual application on the electronic equipments such as digital camera, mobile phone, flat board, and when device orientation change, display and the icon arrangement of screen change thereupon.
Therefore, in a particular embodiment of the present invention, gravity direction can be set to reference direction, existing gravity sensor in electronic equipment can be utilized to come the current direction of perception mobile phone determine whether to carry out acquisition process operation relative to the change of gravity direction, and how to carry out acquisition process operation.
< reference direction is the direction > of the video gathering described destination object described electronic equipment when starting
Describe the rotational case of electronic equipment under first kind of way as a reference with an absolute direction, and respective handling is carried out relative to the change of gravity direction in the current direction of electronic equipment.
But, for video capture, two sections of different video files, do not need to consider that the video file of current shooting remains unchanged relative to the display direction of display frame with destination object in the video file taken before two days, and in the video file only needing maintenance current shooting to obtain, destination object remains unchanged relative to the display direction of display frame.Therefore, this reference direction also can be a relative direction changed with different situations, the direction of described electronic equipment when the video namely gathering described destination object starts.
When homogeneous video acquisition does not start, the direction of electronic equipment is not identical, as long as but the rotational case in the direction of described electronic equipment when recording that in this video acquisition process, electronic equipment direction starts relative to this video, just subsequent treatment can be carried out, maintain this obtain video file play time, the destination object in display frame relative to the display direction of described display frame remain unchanged/or change in a thresholding.
