The method that the present embodiment provides, carries out equal proportion convergent-divergent by picture widescreen data formed, and can ensure that the display of widescreen data distortion can not occur; In addition, height due to image zooming equals height and the preset height sum of preset window, and to determine in image zooming with the in the same size of preset window and after comprising the viewing area of focus area, the widescreen data that this viewing area is corresponding are shown in preset window, therefore, widescreen data integrity can be realized to show on the display device, improve the display effect of widescreen data, thus improve the viewing experience of user.
Embodiment two
Embodiments provide a kind of method showing widescreen data, now in conjunction with the content of above-described embodiment one, the picture that display specification is 4:3 is converted to picture widescreen data formed, to realize showing the picture that widescreen data are formed on the display device of common display specification, in detail explanation is explained to the mode of the display widescreen data that the present embodiment provides.See Fig. 2, the method flow that the present embodiment provides comprises:
201: the picture that widescreen data are formed is carried out equal proportion convergent-divergent, until the height of the picture of widescreen data formation equals height and the preset height sum of preset window, obtain image zooming;
For this step, the equipment of display video picture is when display video picture, interface is made up of three parts usually, as shown in Figure 3, be divided into (5% region outside picture edge, activity safety district, also known as safe frame), place of safety (10% region outside picture edge, comprises activity safety district) and viewing area (not comprising the remainder of activity safety district and place of safety in picture).Video pictures is made up of general data or widescreen data usually, and the ratio of width to height of the picture that widescreen data are formed is 1.442:1, and the ratio of width to height of the picture that general data is formed is 1.067:1; The picture be made up of general data can complete display on the display device with common display specification, and the picture be made up of widescreen data only could complete display on the display device with widescreen display specification.
In this step, why the picture that widescreen data are formed being carried out equal proportion convergent-divergent, is that the picture in order to enable these widescreen data form intactly shows on the equipment of the display video picture preset.Wherein, the implication of equal proportion convergent-divergent is the width convergent-divergent how many times of picture, the height also corresponding convergent-divergent how many times of picture.For the width convergent-divergent of picture 3 times, then in order to realize equal proportion convergent-divergent, the height of picture wants convergent-divergent 3 times too.
When picture widescreen data formed carries out equal proportion convergent-divergent, the height of the picture why widescreen data formed zooms to the height and preset height sum that equal preset window, is to ensure that the main information in the picture that widescreen data are formed all can show with inner region at safe frame.Wherein, the preset height in this step can for being more than or equal to longitudinal width in the activity safety district of normal pictures.
Wherein, the size of preset height specifically can be 5% of picture whole height, and the size of certain preset height, except 5% of picture whole height, can also be other numerical value.Such as, 2% of picture whole height or 3% of picture whole height etc., the size of the present embodiment to preset height does not specifically limit.
202: detect the focus area in image zooming, focus area is the appointed area in image zooming;
Wherein, focus area is the appointed area in image zooming, and this appointed area can be operand region in this image zooming, or main body region in this image zooming, or the geometric center region of this image zooming etc., the concrete form in the present embodiment focusing region does not limit.
When this appointed area is operand region in this image zooming, namely this appointed area refers to the pointer class operand regions such as the cursor of mouse;
When this appointed area is main body region in image zooming, namely this appointed area refers to personage or things region in this image zooming, and such as, the background in a width image zooming is blue sky and white cloud, under a blue sky and magnolia clouds having a child, then child is the main body in this image zooming;
When this appointed area is the geometric center region of image zooming, namely this appointed area refers to the geometric center initial point region in this image zooming.
No matter focus area is specially the region of which kind of type above-mentioned, when detecting the focus area in image zooming, all by image detecting technique, the characteristics of image in image zooming is detected, thus identify the feature of focus area, according to the focus area in the feature in-scope determination image zooming of focus area.Certainly, can also detect the focus area in image zooming by other means, the concrete detection mode in the embodiment of the present invention not focusing region limits.
203: determine in image zooming with the in the same size of preset window and comprise the viewing area of focus area, and in preset window, showing widescreen data corresponding to this viewing area.
For this step, determining with the in the same size of preset window and before comprising the viewing area of focus area, first should determine the size of the preset window showing widescreen data.About the specific implementation of size determining the preset window showing widescreen data, the present embodiment is not specifically limited.In the specific implementation, can after determining to show the equipment of frequency range data, the display screen of this equipment the size of display frame can be defined as the size of preset window.The display screen of the equipment of display widescreen data is different, and the display specification presented naturally also can be different, then the size of preset window also may be different.According to different pictures display specification, the size of the preset window determined is also different from the size of image zooming, as shown in table 1 below:
Table 1
| Picture display specification | The size (taking the upper left corner as initial point) of preset window |
| 16:9 | 0 ~ 100% of image zooming |
| 5:4 | 0 ~ 85% of image zooming |
| 4:3 | 0 ~ 75% of image zooming |
It should be noted that, when performing the method that the present embodiment provides, without the need to all performing the above-mentioned step determining the size of preset window at every turn, and only performing once when the method that first time execution the present embodiment provides.When the size of follow-up preset window and the size of image zooming change, the size determining preset window can be repeated.
No matter adopt which kind of mode to determine the size of the preset window showing widescreen data, when determining in image zooming with the in the same size of preset window and comprise the viewing area of focus area, all can realize in the following way:
Determine the same reference point that preset window is corresponding with image zooming, and be that initial point determines the region of the same size with preset window in image zooming with reference point, and using the region to be shown as image zooming, the region determined;
Determine the position in focus area region relatively to be shown, determine the viewing area of image zooming according to the position in focus area region relatively to be shown.
For the ease of understanding, with the display specification of image zooming for 16:9, the display specification of preset window is 4:3, and preset window and the upper left corner of image zooming are defined as corresponding same reference point is example, then pass through as above table 1 and can know that the size of preset window and the size of image zooming are 0 ~ 75%, as shown in Figure 4.Because preset window and image zooming take same reference point, namely the left hand edge of preset window and the left hand edge of image zooming are as the criterion with the upper left corner and align; Therefore, the region of image zooming 0 ~ 75% is seated in preset window, thus can using the region of 0 ~ 75% of image zooming as region to be shown.
In addition, after the focus area in image zooming detected according to above-mentioned steps 202, just can determine the position in focus area region relatively to be shown, thus judge to show whether this focus area is seated in the region of in this image zooming 0 ~ 75%.Preferably, when determining the viewing area of image zooming according to the position in focus area region relatively to be shown, include but not limited to be divided into following several situation:
The first situation: if determine the position in focus area region relatively to be shown be focus area all in regional extent to be shown, then region to be shown is defined as the viewing area of image zooming.
For this kind of situation, as shown in Figure 5, because focus area is seated in the region of in this image zooming 0 ~ 75%, be also namely seated in preset window, illustrate that when showing region to be shown according to preset window, the content of display can comprise this image zooming main information to be expressed; Therefore, can directly by this image zooming 0 ~ 75% region to be shown be defined as the viewing area of this image zooming.
The second situation: if determine the position in focus area region relatively to be shown to be focus area in regional extent to be shown outer or focus area and region to be shown overlap, then redefine the region of the same size to be shown with preset window in image zooming; Determine the position in the region to be shown that focus area redefines relatively, the viewing area of image zooming is determined in the position in the region to be shown relatively redefined according to focus area.
For this kind of situation, as shown in FIG. 6 and 7, because focus area is seated in outside the region to be shown of in this image zooming 0 ~ 75%, or be seated in (a part of region being arranged in this image zooming 0 ~ 75% of focus area in the edges of regions to be shown of in this image zooming 0 ~ 75%, another part is arranged in outside the region of this image zooming 0 ~ 75%), then illustrate that when showing region to be shown according to preset window, the content of display can not comprise this image zooming main information to be expressed completely; Therefore, the region of the same size to be shown with preset window need be redefined in image zooming, and after determining the position in the region to be shown that focus area redefines relatively, the viewing area of image zooming is determined in the position in the region to be shown relatively redefined according to focus area.
Wherein, in image zooming, redefine the region of the same size to be shown with preset window, include but not limited to:
Redefine reference point according to predetermined threshold value, in image zooming, redefine the region of the same size to be shown with preset window with the reference point redefined for initial point, obtain the region to be shown redefined.
Wherein, the size of predetermined threshold value specifically can be 5% of picture overall width, certainly, the size of predetermined threshold value, except 5% of picture overall width, also can be other numerical value, such as, 2% of picture overall width or 3% etc., the size of the present embodiment to predetermined threshold value does not specifically limit.
For the ease of understanding, continue for Fig. 6, and be 5% of picture overall width with predetermined threshold value be example, because now focus area is positioned at 80% ~ 85% region of this image zooming, if region to be shown is defined as viewing area, the content then shown can not comprise whole main informations of image zooming, therefore, region to be shown need be redefined, and determine the position in the region to be shown that focus area redefines relatively, the viewing area of image zooming is determined with the position in the region to be shown relatively redefined according to focus area, realize 80% ~ 85% region of this image zooming can show in preset window.During concrete enforcement, first this image zooming entirety is moved to the left 5% of picture overall width, then after movement, reference point location place place is 5% region of this image zooming, by 5% ~ 80% region of image zooming as the region to be shown redefined, the displaying contents now in region to be shown is 5% ~ 80% region of this image zooming; Because now focus area is still seated in outside region to be shown, therefore, also need again this image zooming entirety to be moved to the left 5% of picture overall width, after again moving, reference point location place place is 10% region of this image zooming, displaying contents in the region to be shown now redefined is 10% ~ 85% region of this image zooming, because now focus area is seated in the region to be shown redefined, therefore, stop mobile, and current region to be shown the region of 10% ~ 85% (this image zooming) is defined as viewing area.
It should be noted that, region to be shown is redefined except above-mentioned, and determine the position in the region to be shown that focus area redefines relatively, according to focus area relatively described in the position in region to be shown that redefines determine outside the mode of the viewing area of image zooming, other also can be taked to redefine region to be shown, thus determine the mode of viewing area.Such as, this image zooming entirety is moved, until the region be positioned in this image zooming outside former region to be shown is all seated within the region to be shown that redefines, and using the current region to be shown redefined as viewing area, the present embodiment not to redefining region to be shown, thus determines that the mode of viewing area specifically limits.
It should be noted that, when showing widescreen data by above-mentioned steps 201 to step 203, both the picture that widescreen data are formed can be converted to display specification is the picture of 4:3, also the picture that widescreen data are formed can be converted to display specification is the picture of 5:4, and the present embodiment does not specifically limit this.
The method that the present embodiment provides, carries out equal proportion convergent-divergent by picture widescreen data formed, and can ensure that the display of widescreen data distortion can not occur; In addition, height due to image zooming equals height and the preset height sum of preset window, and to determine in image zooming with the in the same size of preset window and after comprising the viewing area of focus area, the widescreen data that this viewing area is corresponding are shown in preset window, therefore, widescreen data integrity can be realized to show on the display device, improve the display effect of widescreen data, thus improve the viewing experience of user.
