Fig. 3 is a kind of flow chart of the projected picture correcting method according to an exemplary embodiment, as shown in figure 3,
The interaction agent of the projected picture correcting method is the projector and mobile device shown in Fig. 1, is comprised the following steps：
In step 301, the projected picture is sent to by the mobile device by the photographic head scanning projection picture for configuring
The projector.
In the present embodiment, projector can be connected with any terminal, and the terminal can provide raw frames for the projector,
The projector projects raw frames on screen, forms projected picture.
Wherein, the terminal can be computer, mobile phone etc., and the raw frames that the terminal is provided in terms of content can be including figure
Piece or word, can be tableaux or dynamic menu etc. on form, and the screen can be the projection side with the projector
To relative barrier or electronic curtain etc., for example, can be one piece of curtain or a face wall, in the present embodiment to this not
Limit.
In projection process, the projected picture for being formed on the screen can be subject to affecting for the running parameter of projector, have
When occur picture it is unintelligible, it is in irregular shape situations such as, affect the bandwagon effect of the projected picture.Now need to the throwing
The running parameter of shadow instrument is corrected, to realize the correction to the projected picture.
And for the ease of correction, mobile device in the present embodiment, being introduced, the mobile device is used for scanning projection picture, with
Just it is corrected according to the projected picture for scanning.
That is to say, the mobile device is configured with photographic head, when user will correct projected picture, open the mobile device
Photographic head, the projected picture being aligned on the screen, and driver sweep operation, then, by the photographic head, scanning should for the mobile device
Projected picture, and the projected picture is sent to the projector.
Wherein, the mobile device can be panel computer, mobile phone etc., and the mobile device sets up data company with the projector
Connect, the projected picture is sent to the projector by the data cube computation.The data cube computation can be bluetooth connection, Wi-Fi connection,
Or other kinds of data cube computation, the present embodiment also do not limited to this.
In step 302, the projector determines correcting scheme according to the projected picture.
In step 303, the projector is corrected to the running parameter of the projector according to the correcting scheme, with school
The just projected picture.
In the present embodiment, the different running parameter of the projector can affect the different aspect of projected picture, for example, projector
Focal length the definition of projected picture, projector can be affected to affect shape of projected picture etc. to the correction amplitude of angle value.
In order to qualified projected picture can be obtained after ensureing correction, after the projector gets the projected picture, can
To be analyzed to the projected picture, the difference between the projected picture and standard picture is determined, so as to according to the difference for determining
Determine correcting scheme, the correcting scheme includes the corrected value of running parameter to be corrected, the corrected value represents the running parameter
Correction amplitude.
Wherein, the standard picture refers to that each side such as definition, shape meet pre-conditioned picture, this it is pre-conditioned can
With the definition including picture more than default definition, so that the difference in the distinguishable picture of human eye between lines, or this is default
What condition can also include picture is shaped as rectangle etc., and the present embodiment pre-conditioned is not limited to this.
As the projector has polytype running parameter, polytype running parameter can be to projected picture
Many aspects are impacted, therefore, using the standard picture as benchmark, according to the difference between the projected picture and the standard picture
It is different to can determine which running parameter needs to correct, and the correction amplitude of these running parameters is specifically how many.
After determining correcting scheme, the projector can be according to running parameter to be corrected and each work to be corrected
The corrected value of parameter is corrected.After correction, the running parameter of the projector changes, and now the projector is according to correction
When running parameter afterwards projects raw frames on screen, projected picture can be caused also accordingly to change so that after correction
It is pre-conditioned that the projected picture for obtaining meets this.
Different running parameters are directed to, determine that correcting scheme and the process being corrected can be with differences.Correspondingly, exist
In a kind of mode in the cards, the shape of projected picture is directed to, step 302-303 comprises the following steps 1 and 2：
1st, the projected picture includes four angles, when the angle value at any one angle in the projected picture is not 90 degree, the throwing
Shadow instrument determines the angle value at each angle and 90 degree of difference, used as the corrected value at four angles of raw frames.
Wherein, four angles of the raw frames include the upper left corner, the upper right corner, the lower left corner and the lower right corner of the raw frames.
Four angles of standard picture are 90 degree, when any one angle in four angles of projected picture is not equal to 90 degree, then it represents that
The projected picture is not standard picture, needs correction.
In order that projected picture is consistent with standard picture, then the angle value and the mark at four angles of the projected picture will be determined
The difference of the angle value at four angles of quasi- picture, that is to say the difference between the angle value and 90 degree for calculating four angles of projected picture
Value.Using each difference for calculating as the corrected value at corresponding angle.
Corrected value can be positive number or negative, and for being directed to each angle, when corrected value is positive number, expression will be original
On the basis of angle value, reduce angle value of the size for corrected value；When corrected value is negative, expression will be in original angle value
On the basis of, increase the angle value of the absolute value that size is the corrected value.
2nd, according to the corrected value at four angles, the projector is corrected to four angles of the raw frames, so that correction
Four angles of the projected picture for obtaining afterwards are 90 degree.
Wherein, the trimming process at any one angle can be carried out using horizontal line or vertical curve as reference line, so that correction
The a line of relief angle be reference line, another a line and the reference line are in 90 degree.
For example, as shown in Figure 3 B, it is assumed that the projected picture is trapezoidal, and the trapezoidal upper left corner be 120 degree, the lower left corner be
60 degree, the upper right corner be 100 degree, the lower right corner be 80 degree, then the upper left corner, the lower left corner, the upper right corner, the difference of the lower right corner and 90 degree are divided
Not Wei 30 degree, -30 degree, 10 degree, -10 degree, therefore, by 30 degree of upper left corner reduction, the corresponding lower left corner can increase 30 degree, and by the right side
Upper angle reduces 10 degree, and the corresponding lower right corner can increase 10 degree, and referring to Fig. 3 C, four angles of the projected picture after correction are 90
Degree.
In the mode of alternatively possible realization, the definition of projected picture is directed to, step 302-303 includes following
Step 3 and 4：
3rd, when the definition of the projected picture is less than default definition, according between the definition and the default definition
Difference, determine the corrected value of focal length.
Wherein, the default definition refers to that human eye can differentiate the definition of the difference between the lines of frame out, the correction
Value refers to the difference between the focal length corresponding to the definition and the focal length corresponding to default definition.
As the focal length of projector is variable, when the focal length corresponding to the focal length reaches default definition, the projection
The definition of picture can reach the default definition, then the projected picture becomes apparent from；When the focal length of the projector is more than
Or during less than focal length corresponding to the default definition, the projected picture can become more to obscure, now the projected picture needs
Correction.
The correction of the projected picture, can be carried out by the focal length of regulation projector.In order that the projected picture is clear
Clear degree reaches default definition, then will determine corresponding to the focal length and the default definition corresponding to the definition of the projected picture
Focal length between difference, using the difference as the corrected value of the projector focal length.
The corrected value can be positive number or negative, when corrected value is positive number, expression will on the basis of original focal length,
Reduce focal length of the size for corrected value；When corrected value is negative, expression will increase size to be somebody's turn to do on the basis of original focal length
The focal length of the absolute value of corrected value.
4th, according to the corrected value of the focal length, the projector is corrected to the focal length of the projector, so as to obtain after correction
Projected picture definition be not less than the default definition.
For example, it is assumed that the corresponding focal length of the default definition is 300cm, and the corresponding focal length of the definition is 295cm, because
This determines that the corrected value of focal length is -5cm, therefore focal length is increased 5cm, and now the definition of the projected picture reaches default clear
Degree.
Assume that the corresponding focal length of the default definition is 300cm, and the corresponding focal length of the definition is 305cm, therefore really
Focus away from corrected value be 5cm, therefore focal length is reduced into 5cm, now the definition of the projected picture reaches default definition.
Projected picture in the present embodiment using scanning is corrected as test pictures according to the test pictures.Correct it
In process afterwards, the terminal can provide multiple raw frames for the projector, when the running parameter for correcting keeps constant
When, it is ensured that the projected picture for being formed subsequently is projected by the projector and is standard picture.Follow-up projection process can be smooth
Carry out, and without the need for correcting projected picture again, the bandwagon effect of the projected picture can also meet the viewing demand of user.
It should be noted that above-mentioned steps are performed by mobile device with step 301, step 302-303 is by projector
As a example by execution, and in another embodiment that the present embodiment is provided, can be with by mobile device execution step 301-302, by throwing

What is should be noted is a little in the present embodiment be only as a example by correcting the definition of projected picture, shape, it is and true
On, can also be adjusted by the brightness to the projected picture, contrast etc., further improve the displaying effect of the projected picture
Really.
Should be noted on the other hand, in the present embodiment, when user passes through mobile device scanning projection picture, even if originally
Projected picture be standard picture, it is also possible to as mobile device is not just causing scanning to projected picture shape to the screen
Shape is irregular, then, it is actually also irregular that the projected picture for obtaining afterwards is corrected according to the projected picture.But
It is, as user is scanned controlling the mobile device with the direction of visual lines of oneself, although the projection obtained after correction
Picture is irregular, but with the direction of visual lines of user oneself from the point of view of, the projected picture remains rule, remains able to meet and uses
The viewing demand at family.
