Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
TV or set-top box of digital video broadcasting (Digital Video Broadcasting, the DVB) standard of support etc.
Terminal usually all supports subtitle (subtitle) function.Pass through electronic program guides (Electronic Program in user
Guide, EPG) or the video window of other application when playing video, the size of subtitle can be according to the video window in video window
The position and size that middle video is currently shown carry out equal proportion scaling.As shown in Figure 1, (that is to say in the display area of terminal 01
The display area of the display screen of terminal 01) in, when video window A is maximized and (be that is to say that video window A is displayed in full screen)
When, the size of subtitle S can also be amplified to the full-size that subtitle S can be shown accordingly.As shown in Fig. 2, with Fig. 1 phase
In the display area of same terminal 01, when video window A is contracted to one jiao of the display area of the terminal 01, subtitle S's
Size also reduces accordingly.
But when video window is contracted to certain size, the size of subtitle accordingly reduces in the video of broadcasting, because
This, may cause it is undersized due to the subtitle so that user can not identify the subtitle, to generate invalid subtitle, finally
Cause terminal because showing that the invalid subtitle generates the wasting of resources.
It, can be with referring to FIG. 3, it illustrates a kind of flow diagram of method for processing caption provided in an embodiment of the present invention
It solves the above problems to a certain extent.The method for processing caption can be applied to terminal, may include steps of.
Step 101 obtains subtitle size threshold.
Step 102 judges whether the size of the subtitle after scaling in a first direction is less than subtitle size threshold, first party
To for either direction.
When step 103, the size of subtitle after scaling in a first direction are less than subtitle size threshold, forbid showing word
Curtain.
It, can be by the subtitle after judgement scaling the in conclusion method for processing caption provided in an embodiment of the present invention
Whether the size on one direction is less than subtitle size threshold, so that the size of subtitle in a first direction after scaling is less than word
When curtain size threshold, forbid showing subtitle.Therefore, when video window is contracted to certain size, subtitle after leading to scaling is the
It, can be by forbidding showing subtitle to avoid terminal because showing resource wave that invalid subtitle generates when undersized on one direction
Take.
Referring to FIG. 4, it illustrates another method for processing caption provided in an embodiment of the present invention.As shown in figure 4, the word
Curtain processing method can be applied to terminal, may include steps of.
Step 201 obtains subtitle size threshold.
The subtitle size threshold can reflect user under its eyesight and certain distance, human eye when watching collection of objects,
Clarity is greater than or equal to the minimum length of the object of clarity threshold in a second direction in collection of objects.Exemplary, this
Two directions can be either direction.When second direction is gravity direction, which be may be considered in a spacing
From place, the row for the subtitle that user can see is high (recommend_height).Wherein, which can be end
The data for directly inputting user are held to store, in this way so that the terminal can directly acquire the subtitle size threshold.
Alternatively, the subtitle size threshold is also possible to what terminal was determined by specific calculation.
Step 202 determines corresponding first number of pixels of subtitle size threshold.
Wherein, the product of size of the subtitle size threshold equal to the pixel of the first number of pixels and terminal in a first direction.
It that is to say the ratio between the size of first number of pixels in a first direction for the pixel of subtitle size threshold and terminal.The first party
To can be either direction.For example, the first direction can be the line direction or column direction of pixel in terminal.
Optionally, the size of the pixel of terminal in a first direction can according to the size of the terminal in a first direction and
The resolution ratio of the terminal determines.It is exemplary, it is assumed that 4K (a kind of resolution standard) TV that terminal is 70 cun.It is shown in the terminal
The width in region is 1550.6mm (millimeter), and height is 872.2mm, and resolution ratio is 4096 × 2160.And assume that first direction is
The column direction (that is to say, the first direction be terminal height direction) of pixel in terminal, then the terminal is in a first direction
Size be 872.2mm, then the size of the pixel of the terminal in a first direction be 872.2 ÷, 2160 ≈ 0.4038mm.?
In a kind of situation, subtitle size threshold is 6.09mm, then corresponding first number of pixels of subtitle size threshold is 6.09 ÷
0.4038≈15.In a second situation, subtitle size threshold is 12.18mm, then corresponding first pixel of subtitle size threshold
Number is 12.18 ÷, 0.4038 ≈ 30.
Step 203 obtains corresponding second number of pixels of size of subtitle in a first direction after scaling.
Wherein, the size of the subtitle after the scaling in a first direction is equal to the pixel of the second number of pixels and terminal the
The product of size on one direction.It that is to say that second number of pixels is the size and terminal of subtitle in a first direction after scaling
Pixel the ratio between size in a first direction.
Continue by taking the example in above-mentioned steps 202 as an example, it is assumed that in the first scenario, the subtitle after scaling is in first party
Upward size is 5.6532mm, then the second number of pixels is 5.6532 ÷ 0.4038=14.In the latter case, after scaling
Subtitle size in a first direction be 11.7102mm, then the second number of pixels is 11.7102 ÷ 0.4038=29.
It should be noted that when using the number of pixel in the terminal to measure the size of subtitle in a first direction,
Terminal can also directly acquire obtained second number of pixels of metering, without by the subtitle after scaling in a first direction
Size is calculated.Reduce the calculation amount of terminal in this way.
Step 204, according to the first number of pixels and the second number of pixels, subtitle after judging scaling is in a first direction
Whether size is less than subtitle size threshold.If the size of subtitle in a first direction after scaling is less than subtitle size threshold,
Execute step 205；If the size of subtitle in a first direction after scaling is greater than or equal to subtitle size threshold, then follow the steps
206。
Terminal can compare the first number of pixels and the second number of pixels.When second number of pixels is less than the first pixel
When number, the size of subtitle in a first direction after determining the scaling is less than subtitle size threshold.When second number of pixels is big
When the first number of pixels, the size of subtitle in a first direction after determining the scaling is greater than or equal to subtitle size
Threshold value.It is exemplary, continue by taking the example in above-mentioned steps 203 as an example.In the first scenario, since the second number of pixels is 14
Less than the first number of pixels 15, accordingly, it is determined that the size of subtitle in a first direction after scaling is less than subtitle size threshold.?
Under second situation, since the second number of pixels is 29 less than the first number of pixels 30, accordingly, it is determined that the subtitle after scaling is the
Size on one direction is less than subtitle size threshold.
Step 205 forbids showing subtitle.
If the size of subtitle in a first direction after scaling is less than subtitle size threshold, the ruler of the subtitle after the scaling
Very little too small, user can not identify the subtitle.It therefore, can be by forbidding showing the subtitle, to avoid terminal because showing invalidation word
The wasting of resources that curtain generates.
Subtitle after step 206, display scaling.
If the size of subtitle in a first direction after scaling is greater than or equal to subtitle size threshold, user can be identified
Subtitle after the scaling can normally show the subtitle after the scaling at this time, normally provide caption function for user.
It should be noted that above-mentioned steps 202 to step 204 is that terminal judges the subtitle after scaling in a first direction
Whether size is less than a kind of implementation of subtitle size threshold.Terminal can also use other modes in the embodiment of the present invention,
Whether the subtitle size in a first direction after judging scaling is less than subtitle size threshold, so that subtitle after scaling is the
Size on one direction can execute step 205 when being less than subtitle size threshold.Subtitle after scaling is in a first direction
Size can execute step 206 when being greater than or equal to subtitle size threshold.Such as: the subtitle after judgement scaling is in a first direction
Size whether to be less than the mode of subtitle size threshold can be the mode that directly compares.The mode directly compared refers to directly
Connect the size and subtitle size threshold of the subtitle after comparing scaling in a first direction.When terminal is using the method that directly compares,
Then without executing above-mentioned steps 202 to step 204, it is directly based upon the comparison result directly compared, executes step 205 or step
206。
In conclusion method for processing caption provided in an embodiment of the present invention, in the eyesight data and sight for considering user
It, can be by judging whether the size of the subtitle after scaling in a first direction is less than subtitle ruler in the case where seeing the factors such as distance
Very little threshold value when so that the size of subtitle in a first direction after scaling being less than subtitle size threshold, forbids showing subtitle.Cause
This when subtitle after leading to scaling in a first direction undersized, can pass through when video window is contracted to certain size
Forbid showing the wasting of resources that subtitle generates to avoid terminal because showing invalid subtitle.Further, by forbidding showing subtitle
It also avoids the invalid subtitle to block video, improves user experience, enhance viewing effect.
In the embodiment of the present invention, when above-mentioned subtitle size threshold needs terminal to be calculated, as shown in figure 5, above-mentioned step
The process of acquisition subtitle size threshold may include: in rapid 201
Step 2011 receives target eyesight data and target viewing distance.
The target eyesight data can be the eyesight data of the user of terminal.The target viewing distance can be the people of user
Eye to terminal distance.Wherein, target eyesight data can be the form of five member records, then the value model of the target eyesight data
Enclosing can be [4.0,5.3].Alternatively, target eyesight data are also possible to the form of decimal record, then the target eyesight data
Value range can be [0.1,2.0].
In embodiments of the present invention, terminal can directly receive user input target eyesight data and target viewing away from
From.Alternatively, terminal can be by carrying out eyesight testing to user, thus according to the eyesight testing as a result, obtaining target eyesight
Data and target viewing distance.
It is exemplary, as shown in fig. 6, it illustrates users in a kind of terminal provided in an embodiment of the present invention to input target eyesight
The interface schematic diagram of data.The interface Z1 of target eyesight data in Fig. 6 may include eyesight (vision) printed words and multiple views
The corresponding selection key X of force data and screen scroll J, multiple eyesight data can reflect the different eyesights of human eye respectively.With
It family can also be in the interface Z1 of the target eyesight data shown by terminal, by selecting multiple eyesight data in step 2011
Corresponding selection key X, to input the eyesight data of the user.When there is no the view of user in the interface Z1 of current goal eyesight data
When force data, user can find hiding eyesight data by pulling screen scroll J.The target eyesight number of terminal default
According to can be 5.0 (that is to say 1.0).
Wherein, can only have the mark of the eyesight data of the form using five member records on selection key X.Alternatively, can also
Only to have the mark of the eyesight data of the form using decimal record.Alternatively, can also have simultaneously using five member records and
The mark of the eyesight data of the form of decimal record.When selection key X has the shape using five member records and decimal record simultaneously
When the mark of the eyesight data of formula, which can satisfy different user and practises to the record of various forms of eyesight data
It is used, improve the experience of user.
It is again exemplary, it is seen as shown in fig. 7, inputting target it illustrates user in a kind of terminal provided in an embodiment of the present invention
See the interface schematic diagram of distance.The interface Z2 of target viewing distance may include the input frame Y of target viewing distance in Fig. 7, with
And the corresponding prompt information of input frame Y " visual range (viewing distance) " of target viewing distance.Target viewing
It may include the first input bit being arranged successively, decimal point, the second input bit and target viewing distance in the input frame Y of distance
Unit (for example, m).Understandable to be, user can also be in the target viewing distance shown by terminal in step 2011
Interface Z2 input frame Y in input the target viewing distance of the user, which can be decimal.Wherein, eventually
The target viewing distance of end default can be the farthest viewing distance stored in the terminal.
Step 2012, in the corresponding relationship of eyesight data and viewing coefficient, the corresponding target of inquiry target eyesight data
Watch coefficient.
Wherein, eyesight data and eyesight are positively correlated, and negatively correlated with viewing coefficient.
Optionally, the corresponding viewing coefficient of eyesight data in corresponding relationship can be with are as follows: human eye is reflected in eyesight data
Eyesight under when watching collection of objects, clarity is greater than or equal to the object of clarity threshold in a second direction in collection of objects
Minimum length.The unit of the viewing coefficient can be mm.Wherein, which may include: and is greater than at a distance from human eye
The object of distance threshold.Exemplary, which may include: that (sighting target can be E for multiple sighting targets in logarithmic visual acuity chart
Word shape).Distance threshold can be 0.5m, 1m or 2m.
Since subsequent needs according to the viewing coefficient determine subtitle size threshold, second direction needs and above-mentioned the
One direction is consistent.Exemplary, when first direction is the line direction of pixel in terminal, second direction is horizontal direction.Or
Person, when first direction is the column direction of pixel in terminal, second direction is gravity direction.
Further alternative, terminal can store the subtitle tune that record has eyesight data and watches the corresponding relationship of coefficient
Whole table.The terminal can inquire the corresponding target of target eyesight data in the subtitle adjustment table for recording the corresponding relationship
Watch coefficient.
It is exemplary, it is assumed that collection of objects is the sighting target of multiple E word shapes in logarithmic visual acuity chart, and second direction is gravity
Direction.Correspondingly, the minimum length of object in a second direction can be the minimum constructive height of object.Above-mentioned subtitle adjustment table can be with
As described in Table 1.

As shown in table 1, when eyesight data are 4.0, the corresponding viewing coefficient of the eyesight data can be 14.54.Eyesight number
According to being 4.1, the corresponding viewing coefficient of the eyesight data can be 11.55.When eyesight data are 4.2, the eyesight data are corresponding
Watching coefficient can be 9.18.
It should be noted that eyesight data can use the form of five member records, or the form using decimal record.That
, which also can recorde the eyesight data using two kinds of forms.Above-mentioned table 1 only has with subtitle adjustment table record
It is illustrated using the eyesight data instance of the form of five member records.
As shown in figure 8, it illustrates a kind of schematic illustrations for calculating viewing coefficient provided in an embodiment of the present invention.In object
In the case that the clarity of body is above-mentioned clarity threshold, the minimum length of object in a second direction and above-mentioned distance threshold at
Direct ratio.And object and human eye in the case where collection of objects includes multiple sighting targets in logarithmic visual acuity chart, in the collection of objects
Distance when being usually 5m, it is clear in the collection of objects when human eye watches collection of objects under the eyesight that eyesight data are reflected
It is sighting target side length (due to logarithmic visual acuity chart that degree, which is greater than or equal to the minimum length of the object of clarity threshold in a second direction,
In, the length and width of sighting target are generally equal, and therefore, the minimum length of object in a second direction is properly termed as sighting target side length).Cause
This, when distance threshold is 1m, viewing coefficient is usually sighting target side length and the ratio between 5.It is exemplary, it is assumed that sighting target side length is
7.27mm, when distance threshold is 1m, which is 1.45mm.
Optionally, which also may include the sighting target side length.Exemplary, as shown in table 2, table 2 is with eyesight number

| 5.2(1.5) | 4.59 | 0.92 |
| 5.3(2.0) | 3.64 | 0.73 |
As shown in table 2, when eyesight data are 4.0 (0.1), the corresponding sighting target side length of the eyesight data is 72.12, corresponding
Watching coefficient can be 14.54.When eyesight data are 4.1 (0.12), the corresponding sighting target side length of the eyesight data is 57.76, right
The viewing coefficient answered can be 11.55.When eyesight data are 4.2 (0.15), the corresponding sighting target side length of the eyesight data is
45.88, corresponding viewing coefficient can be 9.18.
Step 2013 watches coefficient and target viewing distance according to target, determines subtitle size threshold.
Wherein, which watches coefficient with target and target viewing distance is positively correlated.
Optionally, coefficient and target viewing distance are watched according to target, determines that the process of subtitle size threshold may include:
Coefficient, target viewing distance and target formula are watched according to target, determines subtitle size threshold.Wherein, target formula can wrap
It includes:L indicate subtitle size threshold, x indicate target viewing away from
From a indicates that distance threshold, W indicate that target watches coefficient.Exemplary, distance threshold a is usually 1m, and the target is public
Formula can be L=x × W.As a=1, the target formula can simplify, to simplify terminal calculating process, reduce resource and disappear
Consumption.
It is exemplary, it is assumed that distance threshold a=1m.In one case, it is assumed that target viewing distance x is 4.2m, target view
Force data is 5.0.According to above-mentioned table 1 or table 2 it is found that viewing coefficient W is 1.45mm.Subtitle size threshold L=4.2 × 1.45=
6.09mm.In another case, it is assumed that target viewing distance x is 4.2m, and target eyesight data are 4.7.According to above-mentioned table 1 or
Table 2 is it is found that viewing coefficient W is 2.9mm.Subtitle size threshold L=4.2 × 2.9=12.18mm.
