Below in conjunction with embodiment, the handling process shown in Fig. 1 is described in detail, content can be with It is as follows：

In a step 101, target image to be shown is obtained.

In force, the trigger condition that terminal obtains target image to be shown can be diversified.With Family can install the application program with picture browsing function in terminal, when user wishes to browse certain image, When user needs to browse certain image (i.e. target image), user can open the application program, and at this In the image list that application program is provided, the corresponding icon of target image is clicked on, terminal can then receive correspondence The selection instruction of target image, then can obtain target image to be shown.User can also enter in terminal Row changing interface is operated, then terminal can determine interface to be shown according to the switching command of user, and then The background image in the interface can be obtained, as target image to be shown.For example, user can be from certain The desktop of system is switched in the interface of individual application program, then terminal can obtain the wallpaper of desktop, by wallpaper As target image to be shown；Or, user can open certain application program in the desktop of system, then Terminal can obtain the main interface of the application program, and then can obtain the image included in main interface, as Target image to be shown.

In force, terminal is obtained after target image to be shown, can according to default gray scale detection algorithm, The gray level image of target image is obtained, in gray level image, each pixel can be to there is a gray scale Value, then terminal can determine the gray value of each pixel.For three color channels, terminal can basis The channel value of any one color channel of each pixel in target image, obtains the gray level image of target image. For example, terminal can determine the gray level image of target image according to the channel value of the red channel of each pixel； Or the gray level image of target image can be determined according to the channel value of the green channel of each pixel；Also may be used According to the channel value of the blue channel of each pixel, to determine the gray level image of target image.

Optionally, corresponding three gray level images of three color channels of target image can be obtained, accordingly, The processing procedure of step 102 can be as follows：The corresponding gray level image of each color channel of target image is obtained, really The gray value of each pixel included in fixed each gray level image.

In force, terminal is obtained after target image to be shown, can according to default gray scale detection algorithm, Determine the corresponding gray level image of red channel, and determine in the gray level image, each pixel can be corresponded to Gray value.Terminal can determine the corresponding gray level image of blue channel according to default gray scale detection algorithm, And determine in the gray level image, each pixel can corresponding gray value.Terminal can also be according to default Gray scale detection algorithm, determine the corresponding gray level image of green channel, and determine in the gray level image, each Pixel can corresponding gray value.

In force, terminal can be by wide colour gamut come target image, it is also possible to by standard color gamut come Display image.Wherein, in wide colour gamut, the scope of the channel value of each color channel is 0～255, in reference colours In domain, the scope of the channel value of each color channel is then preset range, and preset range is less than 0～255, such as can be with It is 0～200.

Terminal determined after the gray value of each pixel included in gray level image, can count each gray value pair The number of the pixel answered, and then may determine that whether the number of the corresponding pixel of each gray value meets default Randomness change condition.Randomness change condition can be diversified, and for example, terminal counts each After the number of the corresponding pixel of gray value, can obtain the corresponding pixel of each gray value number it is straight Fang Tu, then terminal can calculate the ratio of the number of the corresponding pixel of any two gray value, Ran Houke Whether to judge the ratio as integer, and the number of the ratio of integer can be recorded.If the number is more than Or equal to preset number threshold value, then the number that can be determined that the corresponding pixel of each gray value is unsatisfactory for presetting Randomness change condition, i.e., target image for manual manufacture image, such as user interface image, terminal can Target image is shown with the Src Chan value scope based on each color channel, i.e., terminal can be by wide Colour gamut shows to target image.If the number is less than preset number threshold value, each ash is can be determined that It is natural image that the number of the corresponding pixel of angle value meets default random distribution condition, i.e. target image, Such as the natural land image for shooting, the corresponding rectangular histogram of natural image can be with as shown in Fig. 2 terminal can be by The Src Chan value scope of each color channel is compressed process, the channel value scope pair after being processed based on compression Target image is shown that is, terminal can be shown by standard color gamut to target image.So, base In above-mentioned process, terminal can carry out color gamut conversion, realize entering different types of image call difference colour gamut Row shows.

Optionally, can be judged whether with value according to the number of the corresponding pixel of discrete gray value full The above-mentioned random distribution condition of foot, corresponding processing procedure can be as follows：If there is multiple discrete gray scales The number and value for being worth corresponding pixel is more than predetermined threshold value, then the Src Chan value based on each color channel Scope shows to target image；If there is no the number of the corresponding pixel of multiple discrete gray values And value be more than predetermined threshold value, then the Src Chan value scope of each color channel is compressed into process, be based on Channel value scope after compression is processed shows to target image.

In force, terminal determined after the gray value of each pixel included in gray level image, can be counted every The number of the corresponding pixel of individual gray value, then can determine to having pixel and discrete gray value, As shown in Figure 3.If there is two adjacent gray values all to there is pixel number, then can ignore it In a gray value, for example, the less gray value of corresponding number can be ignored.Terminal can these from In the number of the corresponding pixel of scattered gray value, it is determined that the first number of maximum, and then can determine and The mutually discrete gray value of the corresponding gray value of one number, then can be in these discrete gray values, will most The first big number is added with the second second largest number, then judge to obtain and value whether more than or Equal to predetermined threshold value, if should and be worth be less than predetermined threshold value, by the 3rd the third-largest number with should and value phase Plus, then judge whether what is obtained is more than or equal to predetermined threshold value with value, by that analogy.If there is multiple The number of the corresponding pixel of discrete gray value and value be more than predetermined threshold value, then can based on each color lead to The Src Chan value scope in road shows to target image；If there is no multiple discrete gray value correspondences Pixel number and value be more than predetermined threshold value, then can be by the Src Chan value scope of each color channel Process is compressed, the channel value scope after being processed based on compression is shown to target image.In addition, eventually End can also arrange the threshold value (can be referred to as gray value quantity threshold) of the number of the gray value of addition, if then deposited It is more than predetermined threshold value, and the number of gray value in the number and value of the corresponding pixel of multiple discrete gray values Mesh is less than gray value quantity threshold, then can be based on the Src Chan value scope of each color channel to target image Shown, otherwise, the Src Chan value scope of each color channel can be compressed process, based on pressure Channel value scope after contracting is processed shows to target image.

Optionally, it is also possible to which whether the number for judging the corresponding pixel of each gray value meets linear changing relation, Corresponding processing procedure can be as follows：If the number of the corresponding pixel of each gray value meets linear change pass System, then shown based on the Src Chan value scope of each color channel to target image；If each gray value The number of corresponding pixel is unsatisfactory for linear changing relation, then by the Src Chan value scope of each color channel Process is compressed, the channel value scope after being processed based on compression is shown to target image.

In force, terminal determined after the gray value of each pixel included in gray level image, can be counted every The number of the corresponding pixel of individual gray value, obtains the rectangular histogram of gray value and the number of corresponding pixel, As shown in Figure 4.Terminal can carry out curve by default algorithm (such as method of least square) to these data Fitting, then may determine that whether the curve for obtaining is straight line, or whether can be approximated to be straight line (as respectively The difference of the slope of line segment is in preset range).If what fitting was obtained is straight line, or be can be approximated to be straight Line, the then number that can be determined that the corresponding pixel of each gray value meets linear changing relation, and then terminal can Target image is shown with the Src Chan value scope based on each color channel；If fitting is obtained not It is straight line, or straight line cannot be approximately, then terminal can be determined that the number of the corresponding pixel of each gray value Mesh is unsatisfactory for linear changing relation, then the Src Chan value scope of each color channel is compressed into process, base Channel value scope after compression is processed shows to target image.In addition, if a certain model of terminal judges The number of the corresponding pixel of gray value in enclosing meets linear changing relation, then can determine in the range of this The number of gray value, if the number of the gray value in the range of being somebody's turn to do is more than predetermined threshold value, can be determined that mesh figure Image as being manual manufacture, may then based on the Src Chan value scope of each color channel to target image Shown.

Optionally, can be compressed according to certain proportionate relationship, corresponding processing procedure can be as follows： By the Src Chan value Ratage Coutpressioit of each color channel to default channel value scope；According to default channel value scope With the proportionate relationship of Src Chan value scope, the passage to each color channel of each pixel in target image Value is compressed；Target image is shown based on the channel value after compression.

In force, if the terminal determine that the number of the corresponding pixel of each gray value meets default random Property change condition, then can by the Src Chan value Ratage Coutpressioit of each color channel to default channel value scope, And the proportionate relationship of default channel value scope and Src Chan value scope can be calculated, wherein, preset passage Value scope is less than Src Chan value scope.For example, Src Chan value scope is 0～255, and default channel value is 0～200, then proportionate relationship is 200/255.Terminal determined after proportionate relationship, can according to the proportionate relationship, The channel value of each pixel in target image is compressed, the channel value pair after compression is may then based on Target image is shown.In addition, default channel value scope can also be divided into multiple subranges by terminal, Src Chan value scope is divided into into same number subrange, corresponding two subranges then can be calculated Proportionate relationship, and then according to the proportionate relationship for calculating, the channel value to each pixel in target image It is compressed.

For example, it is 0～200 to preset channel value scope, and its corresponding subrange is 0～100,100～150, 150～200, Src Chan value scope is 0～255, and its corresponding subrange is 0～130,130～200, 200～255, then the ratio that can determine corresponding subrange is：100/130=10/13,150/200=3/4, 200/255=40/51, then be 120*10/13=92, channel value 150 after the compression of channel value 120 in target image It is 150*3/4=112 after compression, is 172 after the compression of channel value 220.

Terminal determines after the channel value after compression process that the channel value that can be based on after compression be entered to target image Row shows.In addition, for three color channels, its corresponding default channel value scope can be identical, Can also be different.

Optionally, for the feelings of corresponding three gray level images of three color channels of above-mentioned acquisition target image Condition, accordingly, the processing procedure of step 103 can be as follows：Respectively in each gray level image, it is determined that often The number of the corresponding pixel of individual gray value, if in each gray level image, existed every in the first gray level image The number of the corresponding pixel of individual gray value meets default random distribution condition, then by each color channel Src Chan value scope is compressed process, and the channel value scope after being processed based on compression is carried out to target image Show；If the number of the corresponding pixel of each gray value in each gray level image be unsatisfactory for it is default with Machine change condition, then shown based on the Src Chan value scope of each color channel to target image.

In force, after corresponding three gray level images of three color channels of terminal acquisition, can randomly select The corresponding gray level image of certain color channel is analyzed, and for example, it is corresponding that terminal can obtain red channel Gray level image, and determining in the gray level image, each pixel can corresponding gray value, then can be with Determine the number of the corresponding pixel of each gray value, and judge the number of the corresponding pixel of each gray value Whether default random distribution condition is met, if it is satisfied, then can be by the Src Chan of each color channel Value scope is compressed process, and the channel value scope after being processed based on compression is shown to target image, such as Fruit is unsatisfactory for, then can be in other two color channel, the corresponding gray level image of one color channel of selection Above-mentioned analysis is carried out, by that analogy.If in corresponding three gray level images of three color channels, there is certain The number of the corresponding pixel of each gray value in individual gray level image (i.e. the first gray level image) meets default Random distribution condition, then the Src Chan value scope of each color channel can be compressed process, and Channel value scope after being processed based on compression is shown to target image；If every in three gray level images The number of the corresponding pixel of individual gray value is unsatisfactory for default randomness change condition, then can be based on each The Src Chan value scope of color channel shows to target image.

Optionally, for less channel value, it is also possible to carry out increase process, corresponding processing procedure can be with It is as follows：In the target image in the channel value of each color channel of each pixel, by less than predetermined threshold value Channel value carries out increase process, and the target image after processing channel value increase shows；In target image In each pixel each color channel compression after channel value in, will be less than predetermined threshold value compression after Channel value carries out increase process, and the target image after processing channel value increase shows.

In force, due to the hardware problem of equipment component, may result in the display effect of target image compared with Difference, such as in target image, the channel value of some pixels is 80, and the passage of the pixel that user sees Value therefore, it can for less channel value to carry out increase process, such as by the passage of the pixel equivalent to 50 Value increases to 100, then user can see pixel of the channel value equivalent to 80.Terminal can be in target figure As in the channel value of each color channel of each pixel, the channel value less than predetermined threshold value is obtained, then The channel value of acquisition is carried out into increase process, terminal can increase channel value according to preset ratio, Channel value can be added default value, the target image after then can processing channel value increase shows Show.When process is compressed to Src Chan value scope, terminal then can be every in the target image In channel value after the compression of each color channel of individual pixel, the channel value less than predetermined threshold value is obtained, so Afterwards the channel value of acquisition is carried out into increase process, and then the target image after processing channel value increase shows Show.

Disclosure another exemplary embodiment provides a kind of method of target image, as shown in figure 5, The handling process of the method can include the steps：

In step 501, target image to be shown is obtained.

In step 502, the gray level image of target image is obtained, each pixel included in gray level image is determined The gray value of point.
