The embodiment of the invention provides a kind of image display method, A referring to fig. 2, this method comprises:
Step 201: when detecting picture rotation instruction, according to picture rotation instruction entrained direction of rotation and rotation
Angle obtains corresponding first pressure from the corresponding relationship between the direction of rotation of storage, rotation angle and the first compression factor
Contracting ratio.
When terminal detects picture rotation instruction, it is necessary first to be compressed along compression direction to picture, it is therefore desirable to
First determine the first compression factor compressed along compression direction to picture, and then can be according to first compression factor to picture
It is compressed.Wherein, terminal determines that the mode of the first compression factor can be with are as follows: according to the entrained rotation side of picture rotation instruction
It obtains and corresponds to from the corresponding relationship between the direction of rotation of storage, rotation angle and the first compression factor to rotation angle
The first compression factor, and the first compression factor that will acquire be determined as along compression direction to picture compressed first compression
Ratio.
It should be noted that picture rotation instruction, which is used to indicate terminal, executes the operation for obtaining the first compression factor, the figure
The entrained direction of rotation of piece rotation instruction and rotation angle can be direction of rotation and rotation angle input terminal by user
The direction of rotation input frame of display is obtained with rotation angle input frame, can also be the direction of rotation shown by user from terminal
In list and rotation angle list, selects a direction of rotation and a rotation angle and obtain.
In addition, direction of rotation entrained by picture rotation instruction includes rotating along X-axis and rotating along Y-axis, picture rotation refers to
Enabling entrained rotation angle is the unspecified angle between 0 degree to 360 degree, such as the direction of rotation that picture rotation instruction is entrained
It can be to rotate 45 degree along X-axis, rotate 60 degree etc. along Y-axis with rotation angle.
Furthermore compression direction is mutually perpendicular to direction of rotation, such as when direction of rotation is along X-axis rotation, compression direction
For Y direction；When direction of rotation is along Y-axis rotation, compression direction is X-direction.
It should also be noted that, the first compression factor can be length and compression of the compressed picture on compression direction
Ratio of the preceding picture between the length on compression direction, certainly, in practical application, the first compression factor can also be picture
Ratio of the picture between the length on compression direction on compression direction before compressed length and compression.
For example, the corresponding relationship between the direction of rotation of terminal storage, rotation angle and the first compression factor can be for such as
Corresponding relationship shown in the following table 1, when detecting picture rotation instruction, the terminal rotation side entrained according to picture rotation instruction
To, to rotate along Y-axis, rotating angle is 45 degree, can be from rotation as shown in table 1 below with rotation angle, such as direction of rotation
In corresponding relationship between direction, rotation angle and the first compression factor, obtains and rotate 45 degree of first corresponding compressions along Y-axis

| It is rotated along X-axis | 45 degree | 0.707∶1 |
| It is rotated along X-axis | 60 degree | 0.500∶1 |
| …… | …… | …… |
| It is rotated along Y-axis | 30 degree | 0.866∶1 |
| It is rotated along Y-axis | 45 degree | 0.707∶1 |
| It is rotated along Y-axis | 60 degree | 0.500∶1 |
| …… | …… | …… |
It should be noted that only with direction of rotation as listed in Table 1, rotation angle and the first pressure in the embodiment of the present invention
It is illustrated for corresponding relationship between contracting ratio, above-mentioned table 1 does not constitute the embodiment of the present invention and limits.
Step 202: according to the first compression factor of acquisition, picture being compressed along compression direction.
For example, when rotation angle is 60 degree, the first compression factor of acquisition can be when direction of rotation is to rotate along X-axis
0.500: 1, terminal can along the y axis compress picture according to the first compression factor of acquisition, and compressed picture exists
The ratio between the length of the picture before length and compression in the Y-axis direction in Y direction is 0.500: 1.
In practical application, terminal can compress picture along compression direction according to the first compression factor of acquisition, when
So, terminal can also by other means compress picture along compression direction.
Step 203: compressed picture will be carried out along compression direction and be divided into multiple picture regions.
On the one hand, the implementation of this step can be with are as follows: determines and carries out compressed picture in compression side along compression direction
Upward length；According to determining length, from the corresponding relationship between the length range and division numbers of storage, obtains and correspond to
Division numbers；According to the division numbers of acquisition, compressed picture will be carried out along compression direction and carries out etc. point dividing, will be obtained more
A picture region.
Wherein, terminal is obtained from the corresponding relationship between the length range and division numbers of storage according to determining length
Take the operation of corresponding division numbers can be with are as follows: terminal, which obtains in the corresponding relationship between length range and division numbers, includes
Multiple length ranges determine from multiple length range and carry out length of the compressed picture on compression direction along compression direction
Length range belonging to degree in the corresponding relationship between length range and division numbers, is obtained based on determining length range
Corresponding division numbers.
For example, the corresponding relationship between the length range and division numbers of terminal storage can be pair as shown in table 2 below
It should be related to, carrying out length L of the compressed picture on compression direction along compression direction can be 10 centimetres, and terminal can obtain
Take 8 centimetres of < L of multiple length ranges for including in the corresponding relationship between length range and division numbers as shown in table 2 below≤
10 centimetres, 10 centimetres of L≤12 centimetre <, 12 centimetres of L≤14 centimetre ... <, and determine from multiple length range along pressure
It is 8 centimetres of L≤10 centimetre <, terminal that contracting direction, which carries out length range belonging to length of the compressed picture on compression direction,
Pair based on determining 8 centimetres of L≤10 centimetre < of length range, shown in the following table 2 between length range and division numbers
In should being related to, obtaining corresponding division numbers is 1000.
Table 2
| Length range | Division numbers |
| 8 centimetres of L≤10 centimetre < | 1000 |
| 10 centimetres of L≤12 centimetre < | 1200 |
| 12 centimetres of L≤14 centimetre < | 1400 |
| …… | …… |
It should be noted that only with shown in table 2 as above between length range and division numbers in the embodiment of the present invention
It is illustrated for corresponding relationship, above-mentioned table 2 does not constitute the embodiment of the present invention and limits.
Multiple pictures are divided into when terminal will carry out compressed picture along compression direction based on above-mentioned equal part division mode
When region, it is only necessary to be divided according to the division numbers of length and determination of the picture on compression direction, so that it may obtain
Multiple picture regions realize that process is fairly simple, and the efficiency for dividing picture is also relatively high；And when division numbers are very big, human eye
It has been difficult to difference in length of multiple picture region on compression direction, therefore has been obtained by equal part division mode multiple
Picture region both can achieve the purpose for dividing picture, while the efficiency for dividing picture is also relatively high.
When terminal, which will carry out compressed picture along compression direction based on the above method, is divided into multiple picture regions, draw
Each picture region being equal in length along compression direction divided, that is to say pressure of the terminal to each picture region along compression direction
Contracting degree is all the same, and certainly, in practical application, the compression degree for each picture region along compression direction be can also be different,
Realization process can be realized by way of following another aspects:
On the other hand, the implementation of this step can be with are as follows: determines that carrying out compressed picture along compression direction is pressing
Length on contracting direction；According to determining length, from the corresponding relationship between the length range and division numbers of storage, obtain
Corresponding division numbers；According to the division numbers of rotation angle and acquisition, from the rotation angle of storage, division numbers and ratio is divided
In corresponding relationship between example, corresponding division proportion is obtained；It will be along pressure according to direction of rotation according to the division proportion of acquisition
Contracting direction carries out compressed picture and is divided, and obtains multiple picture regions, two neighboring picture region in multiple picture regions
Ratio between domain is the division proportion of acquisition.
For example, the corresponding relationship between the length range and division numbers of terminal storage can be right shown in table 2 as above
It should be related to, the corresponding relationship between the rotation angle of storage, division numbers and division proportion can be as shown in table 3 below corresponding
Relationship, direction of rotation can be to rotate along X-axis, and rotation angle can be 45 degree, and terminal determination first is pressed along compression direction
Length of the picture on compression direction after contracting is 10 centimetres；According to determining 10 centimetres of length, terminal can from storage as
In corresponding relationship shown in upper table 2 between length range and division numbers, obtaining corresponding division numbers is 1000；According to rotation
45 degree of gyration and the division numbers 1000 obtained, terminal can be from rotation angle as shown in table 3 below, the division numbers of storage
In corresponding relationship between division proportion, obtaining corresponding division proportion is 1: 1.04；According to the division proportion 1 of acquisition:
1.04, according to along the direction of X-axis, compressed picture will be carried out along the y axis and divided, and obtain multiple picture regions, it is more
Ratio in a picture region between two neighboring picture region is the division proportion 1: 1.04 of acquisition.
Table 3
| Rotate angle | Division numbers | Division proportion |
| 45 degree | 1000 | 1∶1.04 |
| 45 degree | 1200 | 1∶1.03 |
| 45 degree | 1400 | 1∶1.02 |
| …… | …… | …… |
It should be noted that only with rotation angle, division numbers shown in table 3 as above and division ratio in the embodiment of the present invention
It is illustrated for corresponding relationship between example, above-mentioned table 3 does not constitute the embodiment of the present invention and limits.
In addition, in practical application, when mode of the terminal based on above-mentioned another aspect will be carried out along compression direction it is compressed
When picture is divided into multiple picture regions, the last one remaining picture region may be smaller along the length of compression direction, makes
Division proportion of the ratio between the last one picture region previous picture region adjacent thereto not equal to acquisition is obtained,
In this case, picture region can be divided by following two ways, be respectively as follows: the last one picture region and adjacent
Previous picture region merges into a picture region；Alternatively, below the last one picture region or right add one
Divide white space, so that the ratio between the last one picture region after previous picture region and addition white space is equal to
The division proportion of acquisition, and length and the last one picture region be in a rotational direction in a rotational direction for the white space
Equal length.
When ratio cut partition mode of the terminal based on above-mentioned another aspect will carry out compressed picture division along compression direction
When for multiple picture regions, length of each picture region of division on compression direction is different, that is to say from human eye farther out
Length of the picture region on compression direction can be shorter, and the length meeting from the closer picture region of human eye on compression direction
Longer, therefore, obtained multiple picture regions human eye when the length on compression direction is closer to practical rotating image is seen
Length of multiple picture region on compression direction, therefore terminal can make this more by ratio cut partition model split picture
A picture region has more true 3-D effect.
Step 204: according to multiple picture regions in a rotational direction sequence, for multiple picture regions addition mark.
Wherein, when direction of rotation is along X-axis rotation, sequence of the terminal according to multiple picture regions in the X-axis direction, from
Multiple picture regions are successively identified as No. 1, No. 2, No. 3 ... by top to bottm；When direction of rotation is along Y-axis rotation, terminal is pressed
According to the sequence of multiple picture regions in the Y-axis direction, multiple picture regions are successively from left to right identified as No. 1, No. 2,3
Number ....
In practical application, when the picture difference of rotation, the multiple picture regions marked off are also different, in this case eventually
End can be multiple picture regions addition mark, and then according to the mark of addition, execute its mark to multiple picture region respectively
Know corresponding operation, that is to say when direction of rotation is consistent with the rotation angle mark of multiple picture regions all the same, it is right
Multiple picture region executes operation corresponding to the mark, without to each of multiple pictures picture region all
Different operations is executed, so as to so that the image display method all has applicability to different pictures.
Step 205: according to the mark of multiple picture regions, direction of rotation and rotation angle, from the picture region mark of storage
In corresponding relationship between knowledge, direction of rotation, rotation angle and the second compression factor, acquisition is compressed more along direction of rotation
A second compression factor, multiple second compression factor and multiple picture regions correspond.
When terminal needs compress multiple picture regions along direction of rotation respectively, it is necessary first to determine along rotation side
To multiple second compression factors compressed, and then multiple picture regions can be distinguished according to multiple second compression factor
It is compressed.Wherein, terminal determines that the mode of multiple second compression factor can be with are as follows: according to the mark of multiple picture regions,
Direction of rotation and rotation angle, between the picture region mark of storage, direction of rotation, rotation angle and the second compression factor
In corresponding relationship, multiple second compression factors compressed along direction of rotation, and multiple second compression ratios that will acquire are obtained
Example is determined as multiple second compression factors compressed along direction of rotation to multiple picture regions.
It should be noted that the second compression factor can be compressed picture region length and pressure in a rotational direction
Picture region before the contracting ratio between length in a rotational direction, certainly, in practical application, the second compression factor can be with
It is the picture region before picture region in a rotational direction compressed length and compression in a rotational direction between length
Ratio.
For example, the picture region of terminal storage identifies, direction of rotation, rotation angle and the second compression factor between it is corresponding
Relationship can be corresponding relationship as shown in table 4 below, be identified as No. 1 when picture region, direction of rotation be rotated along X-axis, and
When rotation angle is 60 degree, terminal, can be from such as the following table 4 institute according to the mark of the picture region, direction of rotation and rotation angle
In the corresponding relationship between picture region mark, direction of rotation, rotation angle and the second compression factor shown, obtain along rotation side
It is 0.65: 1 to the second compression factor compressed to the picture region.
Table 4
It should be noted that only with picture region mark, direction of rotation, rotation shown in table 4 as above in the embodiment of the present invention
It is illustrated for corresponding relationship between gyration and the second compression factor, above-mentioned table 4 is not constituted the embodiment of the present invention
It limits.
Step 206: according to multiple second compression factors of acquisition, multiple picture regions being pressed respectively along direction of rotation
Contracting.
For example, being identified as No. 1 when picture region, direction of rotation is to rotate along X-axis, when rotation angle is 60 degree, is obtained
The second compression factor can be 0.65: 1, terminal, can be along the x axis to the picture region according to the second compression factor of acquisition
Domain is compressed, the length of the picture region before the length and compression of compressed picture region in the X-axis direction in the X-axis direction
Ratio between degree is 0.65: 1.
For another example, No. 2 are identified as when picture region, direction of rotation is to rotate along Y-axis, when rotation angle is 45 degree, is obtained
The second compression factor taken can be 0.97: 1, and terminal, can be along the y axis to the picture according to the second compression factor of acquisition
