Second embodiment of the present invention is related to a kind of method of determining screen direction, and second embodiment is implemented to first
In mode, according to the image of the first predeterminated position, the act of another method of screen direction when recording the recording image is determined
Example explanation.
Specifically, as shown in Fig. 2, the device for determining screen direction is determined and is recorded according to the image of the first predeterminated position
Screen direction when the recording image includes following sub-step:
Step 201: obtaining the characteristic information and the second class pixel of the first kind pixel in the image of the first predeterminated position
Characteristic information.
Specifically, first kind pixel constitutes first identifier image when screen direction is first direction, the second class pixel is
Pixel in the image of first predeterminated position in addition to first kind pixel.
In one example, screen is the screen of terminal, and first identifier image is the mark image in navigation bar.Inventor
It was found that the color of the mark image of navigation bar can be very big with navigation bar intrinsic colour contrast regardless of what color navigation bar is.Cause
This, determines that the device of screen direction can be by the characteristic information of the pixel of the image of the first predeterminated position of analysis, to determine record
Make the screen direction when recording image.
In one example, the characteristic information of first kind pixel is the average brightness of first kind pixel, the second class pixel
Characteristic information be the second class pixel average brightness.Wherein, brightness can be " Y " component in YUV image.
It should be noted that it will be understood by those skilled in the art that in practical application, in addition to can be according to average brightness
In image to judge the first predeterminated position whether include first identifier image, can also by other characteristic informations of pixel come
Confirm whether the first predeterminated position includes first identifier image, and present embodiment does not limit for judging whether to include first identifier
The characteristic information of the pixel of image.
Step 202: calculating the first difference of the characteristic information of first kind pixel and the characteristic information of the second class pixel, and root
Whether it is greater than the judging result of first threshold according to the first difference, determines screen direction.
Specifically, due to the color of the mark image of navigation bar can be it is very big with navigation bar intrinsic colour contrast,
It, can by calculating the difference of the characteristic information of the corresponding first kind pixel of first identifier image and the characteristic information of the second class pixel
Whether to include that first identifier image provides judgment basis in the image to determine the first predeterminated position.
Below to the judging result for whether being greater than first threshold according to the first difference, determine that the mode of screen direction is lifted
Example explanation.
First example determines the device of screen direction if it is determined that the first difference determines screen direction greater than first threshold
For first direction, however, it is determined that the first difference is not more than first threshold, determines that screen direction is second direction.
Specifically, illustrating the characteristic information and the second class pixel of first kind pixel if the first difference is greater than first threshold
Characteristic information diversity ratio it is larger, i.e., the color of the first identifier image of first kind pixel and the colour-difference of the first background image away from
It is bigger, it include first identifier image in the image of the first predeterminated position, therefore screen direction is first direction.On the contrary, first is poor
Value is not more than first threshold, then account for screen direction is second direction.
Second example only includes a kind of color in first identifier image.The device of screen direction is determined if it is determined that first
Difference is greater than first threshold, judges whether the difference of the characteristic information between any two first kind pixel is respectively less than third threshold
Value；If it is determined that the difference of the characteristic information between any two first kind pixel is respectively less than third threshold value, determine that screen direction is
First direction；If it is determined that there are the differences of the characteristic information between two first kind pixels to be not less than third threshold value, it is determined that screen
Curtain direction is second direction, however, it is determined that the first difference is not more than first threshold, it is determined that screen direction is second direction.
Specifically, illustrating the characteristic information and the second class pixel of first kind pixel if the first difference is greater than first threshold
Characteristic information diversity ratio it is larger, i.e., the color of the first identifier image of first kind pixel and the colour-difference of the first background image away from
It is bigger, illustrate under maximum probability, includes first identifier image in the image of the first predeterminated position.It is final to further increase
The accuracy of judging result determines that the device of screen direction is further judged based on the characteristic information of first kind pixel,
Since first identifier image only includes a kind of color, then the characteristic information of first kind pixel is identical or extremely close, therefore determines screen
The device in curtain direction judges whether the difference of the characteristic information between any two first kind pixel is respectively less than third threshold value, if really
It surely is that then screen direction is first direction.If being unsatisfactory for the condition that the first difference is greater than first threshold, alternatively, any two the
Whether the difference of the characteristic information between a kind of pixel is respectively less than the condition of third threshold value, then screen direction is second direction.
It is noted that the characteristic information based on first kind pixel, further determines screen direction, improve
The accuracy of judging result.
Third example determines the device of screen direction in the judgement knot for whether being greater than first threshold according to the first difference
Fruit before determining screen direction, before or after calculating the first difference, obtains the image for recording the second predeterminated position of image
In third class pixel characteristic information and the 4th class pixel characteristic information；Wherein, when screen direction is first direction, second
It include second identifier image in the image of predeterminated position, third class pixel constitutes second identifier image, and the 4th class pixel is second
Pixel in the image of predeterminated position in addition to third class pixel.Calculate the characteristic information and the 4th class pixel of third class pixel
Second difference of characteristic information.Determine whether the device of screen direction is greater than the judging result of first threshold according to the first difference,
And second difference whether be greater than the judging result of second threshold, determine screen direction.
In one example, determine that the device of screen direction judges whether the first difference is greater than first threshold；If first is poor
Value is greater than first threshold, it is determined that screen direction is first direction；If it is determined that being not more than first threshold for the first difference, the is judged
Whether two differences are greater than second threshold；If it is determined that being greater than second threshold for the second difference, it is determined that screen direction is first direction；
If it is determined that being no more than second threshold for the second difference, determine that screen direction is second direction.
In another example, determine that the device of screen direction judges screen direction by following steps:
Step 2021: judging whether the first difference is greater than first threshold.If the determination result is YES, 2022 are thened follow the steps,
Otherwise, step 2023 is executed.
Step 2022: judging whether the difference between the characteristic information of any two first kind pixel is respectively less than third threshold
Value.If the determination result is YES, step 2025 is executed.Otherwise, step 2023 is executed.
Step 2023: judging whether the second difference is greater than second threshold.If the determination result is YES, 2024 are thened follow the steps,
Otherwise, step 2026 is executed.
Step 2024: judging whether the difference between the characteristic information of any two third class pixel is respectively less than the 4th threshold
Value.If the determination result is YES, step 2025 is executed, otherwise, executes step 2026.
Step 2025: determining that screen direction is first direction.
Step 2026: determining that screen direction is second direction.
It is noted that determining screen direction using the judging result of two predeterminated positions as foundation, further improve
The accuracy of determining screen direction.
In one example, the characteristic information of third class pixel is the average brightness of third class pixel, the 4th class pixel
Characteristic information be the 4th class pixel average brightness.
It should be noted that it will be understood by those skilled in the art that can be vertical according to screen direction in practical application
When direction, the difference of the characteristic information of the characteristic information and first kind pixel of the second class pixel determines first threshold, the 4th class
The difference of the characteristic information of the characteristic information and third class pixel of pixel determines second threshold, for example, if screen direction is perpendicular
Histogram to when, the difference of the characteristic information of the characteristic information and first kind pixel of the second class pixel is 10, the spy of the 4th class pixel
The difference of reference breath and the characteristic information of third class pixel is 9, then first threshold is 9 or 10, and second threshold is 8 or 9.
It should be noted that it will be understood by those skilled in the art that in practical application, to further increase screen direction
Accuracy, can according to the image of the first predeterminated position, the image of the second predeterminated position, third predeterminated position image ...
