Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in restriction the present invention.
Referring to Fig. 1, the main method flow process of video preview is as follows in the embodiment of the invention:
Step 101: receive the selection play instruction to the image of showing; Wherein, the image of displaying is: the image that extracts from video at interval, and the image that displaying is extracted in the three-dimensional scenic that makes up in advance at preset timed intervals.
Preset Time can be the time interval of geometric ratio at interval, also can determine according to a plurality of programs that comprise in the video or the time of content.
Step 102: begin to play described video from the image of selecting.
Begin displaying video after embodiment of the invention realization is operated the image of video preview, video preview and video playback are effectively combined, simplify the step from the video preview to the video playback.
In the embodiment of the invention, can carry out the image that from video, extracts showing in three-dimensional scenic with 3-D effect after image is handled that the image of selecting then to show carries out video playback, particularly, referring to Fig. 2, the method detailed flow process of first kind of video preview is as follows in the embodiment of the invention:
Make up a three-dimensional scenic in advance, determine quantity, the display location of exploded view picture in the three-dimensional scenic, the attribute of each display location.Wherein, the attribute of each display location can comprise in following one or multinomial: the 3D shape of three-dimensional rotation angle, image, illumination arrange etc.For example, arrange and show 13 width of cloth images in this three-dimensional scenic altogether, wherein, the three-dimensional rotation angle in centre position is 0 °, and the three-dimensional rotation angle of both sides image is respectively clockwise 15 ° and counterclockwise 15 °.
Step 201: obtain in advance quantity, the display location of exploded view picture in the three-dimensional scenic that makes up, the attribute of each position.
Step 202: according to the quantity of exploded view picture in the three-dimensional scenic, from video, extract image at preset timed intervals at interval.
Preferably, image is extracted in beginning to both sides centered by the interlude of current video.
Step 203: be the display location in the image distribution three-dimensional scenic that extracts.
In this step, in the three-dimensional scenic that makes up in advance, distribute display location for the image that extracts according to the sequencing of image in video that extracts.
Step 204: according to the attribute of each display location in the three-dimensional scenic, the image of each display location correspondence is carried out three-dimension varying.
Three-dimension varying comprises geometric transformation (under same coordinate system object being moved to another position from a position), transformation of scale, rotation transformation etc.
Main three-dimensional rotation angle according to image is rotated conversion and geometric transformation in the present embodiment, the three-dimensional rotation angle in centre position for example is 0 ° in the three-dimensional scenic of Gou Jianing in advance, the three-dimensional rotation angle of both sides image is 15 ° (anglec of rotation of each image also can be different), image is carried out the three-dimensional rotation conversion, reflect the depth feelings of preview image, image is positioned over the position of distributing to image by geometric transformation then.
Step 205: the image behind the three-dimension varying is showed in the three-dimensional scenic that makes up in advance.
In the three-dimensional scenic that makes up in advance, show the effect of the image after carrying out three-dimension varying for example as shown in Figure 3, can show 13 images in this three-dimensional scenic that makes up in advance, 1-13 represents the numbering of each image among the figure, the image top in centre position can show the time that the image in centre position is play in video, the image in centre position is normal demonstration (being that the three-dimensional rotation angle is 0 °), the image of both sides is symmetry axis with the centre position, arranges relatively and shows.The rotation number of degrees of both sides image are identical, and for example Zuo Ce image all is rotated counterclockwise 15 °, and the image on right side all turns clockwise 15 °; The rotation number of degrees of each image also can be different, and for example, the position decentre of image is more far away, and the anglec of rotation is more big.
Step 206: receive the selection play instruction to the image of showing.
Step 207: begin to play described video from the image of selecting.
The embodiment of the invention by according to each position in the three-dimensional scenic that makes up in advance attribute, extraction image from video is carried out three-dimension varying makes the image of showing have 3-D effect, exploded view picture in the three-dimensional scenic that makes up in advance, make that the displaying of image is regular, the convenient image of selecting to show is play.
Also propose a kind of method of controlling video preview in the embodiment of the invention, this method is used at intelligent terminal, and on the equipment such as remote controller, referring to Fig. 4, the method detailed flow process is as follows:
Step 401: judge whether to detect the selection that the image of showing is carried out and play gesture; Wherein, the image of displaying is: the image that extracts from video at interval, and the image that displaying is extracted in the three-dimensional scenic that makes up in advance at preset timed intervals.
Select to play gesture and for example be behind the image of selecting to show the intelligent terminal of band touch-screen carried out and double-click, simple operations such as click; The button remote controller is carried out button operation etc.
Step 402: when detecting the selection broadcast gesture that the image of displaying is carried out, send the selection play instruction to the image of showing, comprise the image that described selection broadcast gesture is selected in the described selection play instruction.
The embodiment of the invention realizes the control to video preview, effectively the image of video preview and video playback is carried out relatedly, simplifies the step from the video preview to the video playback.
Also propose a kind of device of video preview in the embodiment of the invention, referring to Fig. 5, this device comprises:
Playing module 502 is used for beginning to play described video from the image of selecting.
Referring to Fig. 6, described device also comprises: module 503 is set, is used for making up three-dimensional scenic in advance, the attribute of the three-dimensional scenic of Gou Jianing comprises the attribute of quantity, display location and each display location of exploded view picture in advance.
