Background
Currently, as the screen size of the mobile terminal is larger and larger, the screen aspect ratio is also developed from 16 to 19.5, and even 20, but the ratio of the screen width is not increased, which results in that when the mobile phone views some "long and narrow" pictures with the transverse dimension much larger than the longitudinal dimension, the user needs to manually zoom in and continuously slide the screen to see the complete picture.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a picture display method, which is applied to a terminal and is shown in figure 1, aiming at the problem that a user cannot conveniently view a picture under the condition that the length-width ratio of the picture is unbalanced because the transverse size is far larger than the longitudinal size in the prior art, and comprises the following steps:
step 11: and under the condition that the ratio value between the transverse size and the longitudinal size of the target picture is greater than or equal to a first threshold value, acquiring the ratio of the text content in the target picture.
The target picture may be a picture that is not selected for enlarged display and is in a thumbnail browsing state, and the first threshold may be 2, but is not limited thereto.
Step 12: and displaying the target picture according to the proportion of the text content.
Specifically, different forms of display can be performed for pictures with more text information and pictures with less text information (even without text information): text content can be extracted from pictures with more text information and displayed at a proper position on a terminal screen, and pictures with less text information can be displayed in a maximum size in a horizontal screen mode on the premise of ensuring definition, but the method is not limited to the above.
According to the image display method provided by the embodiment of the invention, under the condition that the ratio value between the transverse size and the longitudinal size of the target image is greater than or equal to the first threshold value, the proportion of the text content in the target image is acquired; displaying the target picture according to the proportion of the text content; the display of different forms can be realized to the picture that the literal information is more and the picture that the literal information is less (even there is no literal information) to the user looks over: the method comprises the following steps that text content can be extracted from pictures with more text information and displayed at proper positions on a terminal screen, and pictures with less text information can be displayed in a maximum size in a horizontal screen mode on the premise of ensuring definition; the problem that in the prior art, a user cannot conveniently view the picture under the condition that the length-width ratio of the picture is unbalanced due to the fact that the transverse size is far larger than the longitudinal size is well solved.
Wherein, the displaying the target picture according to the proportion of the text content comprises: under the condition that the proportion of the text content is greater than or equal to a second threshold value, extracting the text content in the target picture; and displaying the target picture in a first area on a display screen of the terminal, and displaying the text content in a second area on the display screen of the terminal.
That is, for pictures with more text information, text content can be extracted and displayed at a proper position on a terminal screen, and a target picture is displayed at the same time so as to be convenient for a user to view; the second threshold may be 0.5, the second area may be an area on the display screen of the terminal other than the first area, or the second area may be an area on the display screen of the terminal overlapping with the first area, or even the second area may be the same area as the first area, that is, completely overlapping.
Further, the displaying the target picture according to the proportion of the text content further includes: and under the condition that the proportion of the text content is smaller than a second threshold value, amplifying the target picture by adopting a horizontal screen display mode and then displaying the amplified target picture.
That is, for the picture with less text information (even without text information), the target picture can be displayed in an enlarged manner in a horizontal screen manner, so that the user can conveniently view the target picture.
Specifically, the displaying the target picture after being amplified in a landscape display mode includes: and under the condition that the proportional value between the transverse size and the longitudinal size of the target picture is kept unchanged, stretching the transverse size of the target picture to be consistent with the longitudinal size of the display screen.
That is, for a picture with little text information (even without text information), the target picture can be displayed in the largest size as possible so as to be convenient for the user to view.
Further, the displaying the target picture after being amplified by using a landscape display mode further includes: after the transverse size of the target picture is stretched to be consistent with the longitudinal size of the display screen, acquiring a first definition of the stretched target picture; if the first definition is larger than or equal to a third threshold value, displaying the stretched target picture in a horizontal screen display mode; if the first definition is smaller than the third threshold, repeatedly executing the reduction of the stretched target picture in a preset proportion, and displaying the reduced target picture in a horizontal screen display mode after the preset reduction times are reached or the definition of the reduced target picture is larger than or equal to the third threshold.
That is, for pictures with less text information (even without text information), the pictures can be displayed in a maximum size in a horizontal screen mode on the premise of ensuring the definition, so that the pictures can be conveniently viewed by a user. The "reaching of the preset zoom-out number" may be understood as that the current definition is empirically confirmed to be closer to the target definition (the third threshold), and in order to ensure that the current definition is convenient for the user to view to the maximum extent, the target picture is not zoomed out any more, and the target picture is displayed in the current size. The first resolution may be 30, the predetermined number of reduction times may be 2, and the predetermined ratio may be 0.9; when the target picture is reduced, the horizontal size and the vertical size of the target picture may be reduced, for example, the horizontal size is reduced to 0.9 times of the current horizontal size, and the vertical size is reduced to 0.9 times of the current vertical size.
Further, after the transverse size of the target picture is stretched to be consistent with the longitudinal size of the display screen, under the condition that the longitudinal size of the stretched target picture is larger than the transverse size of the display screen, displaying a partial area of the stretched target picture on the display screen; and updating the partial region after detecting a preset operation for the partial region.
That is, for an area that is not displayed, display may be performed by dragging a partial area that is already displayed on the display screen, i.e., updating the partial area, so that the display content is adjusted based on the updated partial area. Of course, the content in the partial region may be dragged and the content displayed in the partial region may be updated, so that the content displayed in the partial region is adjusted based on the adjustment of the content in the partial region, so that the user can view the picture content.
The picture display method provided by the embodiment of the invention is further explained below.
In order to solve the above technical problem, an embodiment of the present invention provides a method for displaying a picture, and in particular, a method for acquiring and presenting content for a long and narrow picture whose lateral size is much larger than a longitudinal size; according to the scheme provided by the embodiment of the invention, the transverse size and the longitudinal size of the target picture are obtained, the ratio of the transverse size and the longitudinal size of the target picture is calculated, and whether the target picture is a long and narrow picture is judged. For a long and narrow picture, the content of the picture is detected, the text information is read for the picture (text picture) with more text information, and the picture characters are sorted by selecting a proper position, so that the user can conveniently check the picture characters. For non-text pictures, the definition degree of the pictures is calculated by using an image detection method, a horizontal screen is selected to be displayed on an interface, and the size of the displayed pictures is ensured to be the maximum on the basis of ensuring the definition.
Specifically, as shown in fig. 2, the scheme provided by the embodiment of the present invention includes:
step 21: and acquiring a proportional value between the transverse size and the longitudinal size of the target picture.
Specifically, when the user opens the picture using the terminal in the vertical screen, the ratio between the horizontal size and the vertical size of the target picture may be obtained.
In actual use, the transverse size and the longitudinal size of the target picture are basic attributes of the picture; for a non-rectangular irregular picture, the transverse size of the picture is the maximum transverse size of the picture, and the longitudinal size of the picture is the maximum longitudinal size of the picture; such as the oval picture shown in fig. 3, its lateral and longitudinal dimensions in the terminal are the lateral and longitudinal dimensions a, b of its peripheral rectangle.
Step 22: whether the ratio of the transverse dimension to the longitudinal dimension is greater than a first threshold value is determined (i.e., whether the transverse dimension is greater than the longitudinal dimension is determined), if so, step 24 is performed, and if not, step 23 is performed.
When the transverse size of the target picture is more than 2 times of the longitudinal size, the ratio imbalance between the transverse size and the longitudinal size can be considered, and the picture which is inconvenient for the user to view in the vertical screen state, namely the long and narrow picture, is judged.
Step 23: and directly displaying the target picture (only by adopting the existing means, the description is omitted).
Step 24: and performing text detection on the target picture, and acquiring the proportion of the area of the text content in the target picture in the whole area of the target picture (namely the proportion of the text content).
Step 25: and determining whether the target picture is a text picture according to the ratio obtained in the step 24 (i.e., determining whether the ratio of the text content is greater than or equal to a second threshold), if so, entering a step 26, otherwise, entering a step 27.
Specifically, text detection and region division can be performed on the target picture, so as to judge whether the target picture is a text picture;
after the proportional imbalance between the horizontal size and the vertical size of the target picture is judged, text content detection is carried out on the target picture. Specifically, characters in the current picture can be detected through an image processing technology; after the text is detected, the text region and the non-text region can be divided, and specifically, when the text region accounts for more than 50% of the picture, the target picture is judged to be the text picture.
Step 26: the text content is extracted line by line and the target picture is displayed in a first area on the screen of the terminal (the currently displayed page) and the text content is displayed in a second area on the screen of the terminal.
Here, the content characters of the target picture are acquired line by line, and the characters are read line by line in a row unit when the characters are extracted. The read text may be stored in the memory, and after the reading is completed, the obtained text is displayed line by line in a non-picture display area (i.e., the second area) on the screen of the terminal, and a target picture is displayed in a picture display area (i.e., the first area), as shown in fig. 4.
Step 27: and calculating the definition (which can be resolution) of the picture content, and displaying the horizontal screen of the picture content on the screen of the terminal according to the definition.
In particular, the horizontal screen maximally displays a non-text picture (target picture):
for non-text pictures, the scheme displays the picture cross screen, and displays the picture cross screen to a user in an enlarged mode as far as possible.
More specifically, when displaying, the transverse dimension of the target picture is stretched to be consistent with the longitudinal dimension of the terminal, and the ratio between the transverse dimension and the longitudinal dimension of the target picture is ensured to be unchanged in the stretching process, as shown in fig. 5.
Further, since the image is enlarged, there is a possibility that the enlarged target image is blurred, and an exemplary method for detecting the image sharpness is provided in the embodiment of the present invention: specifically, the method comprises the following steps: the image on the right side of the image in fig. 5 can be taken as a snapshot, and then the image definition of the snapshot is detected in the background; generally, an image with high image definition has sharper edges and larger gradient values, and for the same picture, the smaller the size is, the sharper the edges are; therefore, in the embodiment of the present invention, the Laplacian gradient function is used to calculate the sharpness of the image, and the sharpness function of the image is defined as follows:
D(f)＝∑ y ∑ x g (x, y) |, where G (x, y) > T;
d (f) represents definition, x represents the abscissa of the pixel point (x, y), y represents the ordinate of the pixel point (x, y), G (x, y) represents the convolution of a Laplacian operator at the pixel point (x, y), and T represents the threshold value of the convolution;
a threshold T =50 is set, specifically, G (x, y) is of the form:
In the state of T =50, it is empirically known that if the value of D (f) exceeds 30, it is determined that the image is clear, and if the value of D (f) of the snapshot in the current size is lower than 30, it is determined that the image is unclear, at this time, the horizontal size and the vertical size of the target picture are scaled down to 0.9 times of the first size (specifically, the current size) (i.e., the horizontal size is scaled down to 0.9 times of the horizontal size in the first size, and the vertical size is scaled down to 0.9 times of the vertical size in the first size), and the snapshot is formed again and the sharpness value is calculated, if the sharpness value is greater than 30, the target picture is presented on the screen by 0.9 times of the first size, and if the value is still smaller than 30, the horizontal size and the vertical size of the target picture are further scaled down to 0.9 × 0.9 times of the first size, and the sizes (the horizontal size and the vertical size) obtained after the scaling down are taken as the final presentation size. Specifically, the detecting and scaling process may be as shown in fig. 6, and includes:
step 61: starting;
step 62: calculating a definition D (f) value of the target picture snapshot under the current size;
and step 63: judging whether the value D (f) is larger than 30, if so, entering a step 66, and if not, entering a step 64;
step 64: judging whether the zooming (reducing) times of the target picture reach 2 times, if so, entering a step 66, and if not, entering a step 65;
step 65: reducing the transverse size and the longitudinal size of the target picture to be 0.9 of the current size in an equal proportion;
and step 66: presenting (displaying) the target picture in the current size;
step 67: and (6) ending.
From the above, the scheme provided by the embodiment of the invention can realize content detection on the long and narrow picture with the transverse size far larger than the longitudinal size, directly extract and display characters in the picture on the page through an image processing algorithm for the picture with most of the content being text, and ensure that the size of the picture presented to a user is the largest on the premise of ensuring the definition for a non-text picture (the picture with most of the content not being text), thereby facilitating the user to check the text and the picture content.
An embodiment of the present invention further provides a terminal, as shown in fig. 7, including:
a first obtaining module 71, configured to obtain a ratio of text content in a target picture when a ratio value between a transverse size and a longitudinal size of the target picture is greater than or equal to a first threshold;
and the first display module 72 is configured to display the target picture according to the proportion of the text content.
The terminal provided by the embodiment of the invention obtains the proportion of the text content in the target picture under the condition that the proportion value between the transverse size and the longitudinal size of the target picture is greater than or equal to a first threshold value; displaying the target picture according to the proportion of the text content; the display of different forms can be realized to the picture that the literal information is more and the picture that the literal information is less (even there is no literal information) to the user looks over: the method comprises the following steps that text content can be extracted from pictures with more text information and displayed at proper positions on a terminal screen, and pictures with less text information can be displayed in a maximum size in a horizontal screen mode on the premise of ensuring definition; the problem that in the prior art, a user cannot conveniently view the picture under the condition that the length-width ratio of the picture is unbalanced due to the fact that the transverse size is far larger than the longitudinal size is well solved.
