In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, described embodiment Only some embodiments of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this field Those of ordinary skill's every other embodiment obtained without making creative work, belongs to guarantor of the present invention The range of shield.

Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool The purpose of the embodiment of body, it is not intended that in the limitation present invention.

Fig. 1 is the flow chart of the image processing method of first embodiment of the invention, it should be noted that present embodiment Described image processing method is not limited to step and sequence in flow chart shown in FIG. 1.Shown process according to different requirements, Step in figure can increase, remove or change sequence.

First better embodiment of the image processing method of present embodiment may include following steps:

Step 100, the attribute information that source file in application includes each image file is obtained.

It is to be appreciated that the application is mountable in terminal (such as smart phone), to realize specific function, including But it is not limited to the functions such as social activity, short message.It is to be appreciated that may may require that several images in an application, it is better to provide User interface.Thus, it may include one or more image files in the source file of the application.

Preferably, the attribute information of each image file (each image file) includes but is not limited to the name of image file The information such as title, type, size, position, size.For example, the name information of image file can be sample.png, sample@ 2x.png, sample@3x.png etc.；The type information of image file may include the lattice of the types such as polar plot or bit map/bitmap Formula, such as svg, jpeg, png, bmp, wherein the type information of image file can include from image file name information It is obtained in extension name, the entitled png of extension as corresponding in the image file of entitled sample.png therefore can be true The type for determining image file sample.png is then png；The dimension information of image file is image pixel dimensions, e.g., 30px* 30px (pixel), 48px*48px, 200px*200px etc.；The location information of image file can be image file in source file Interior path, location information can be relative path or absolute path；The size information of image file is shared by image The size of memory space, such as 32KB, 54KB, 1MB.

Preferably, included source file can entirely be applied by traversing, to obtain corresponding to the attribute of each image file Information.It is prepared in file in addition, the attribute information for the image file that traversal obtains after entire can be can be stored in.Wherein, described Each settable different file identification of image file in file is prepared, therefore, in the preparation file, each file identification can Corresponding to information such as the title of image file, type, size, position, sizes.

Step 102, filter operation is executed according to the name information of each image file, to obtain one or more images Group, wherein each image group contains the same image of different dimension informations.

In order to make using varying environment or terminal screen is adapted to, there are the file of a variety of sizes, difference masters for an image It will be in size, thus, it will usually it is distinguished by different titles, for example, for the screen size of 1:1, described image The title of file can are as follows: sample.png (1 times of figure)；For the screen size of 1:2, the title of described image file can are as follows: Sample@2x.png (2 times of figures)；For the screen size of 1:3, the title of described image file can are as follows: sample@3x.png (3 Scheme again).Thus, image file name filter operation can be executed according to the name information of image file.

It is to be appreciated that the name information of several image files can be obtained from configuration file, and to several image files Title matched, if it exists the difference of the title of image file be specific preset characters (such as above-mentioned 2x, It 3x), then can be using these images of title difference on specific character as an image group.It specifically, can be first from preparation The name information of each image file is obtained in file, later, the preset characters that the name information of image file includes can be removed, And judge whether there is the identical two or more image files of name information after removal preset characters, and if it exists, can will then go Except name information is identical described two after preset characters or multiple images file is as image group, such as by corresponding file identification Image file as image group.For example, name information sample.png, sample@2x.png, the sample@of image 3x.png and abc@2x.jpg remove preset characters after be respectively sample.png, sample.png, sample.png and abc.jpg.Wherein, sample.png can correspond to the first file identification, and sample@2x.png can correspond to the second file identification, Sample@3x.png can correspond to third file identification, and abc@2x.jpg can correspond to the 4th file identification.Due to removing preset characters First is sample.png to the name information of image corresponding to third file identification afterwards, can be used as same image, and The name information of four file identification institute images is abc.jpg.It therefore, can be by first to the text of image corresponding to third file identification Part is as the first image group.

For this image group, to reduce the volume size after being packaged, wherein one can be only retained in the source file of application Image, to obtain retaining image, and other image files then can be used as and be replaced image, can will also be replaced image from answering It is deleted in source file.For example, above-mentioned image sample.png, sample@2x.png, sample@3x.png can make For an image group, and in three images any one can retain, and other can then be deleted as the file for being replaced image. Certainly, it also can need to retain wherein one according to realizing.

Step 104, texture feature extraction is carried out to each described image file, and the similarity of textural characteristics is greater than in advance If two or more described image files of value are as image group.

It is to be appreciated that the textural characteristics of some image files may be same or similar in the source file of application, but its Image file name has differences, thus, it is identical being likely present after image file name filter operation, in source file Or similar image.Wherein, identical image can be expressed as image file textural characteristics it is identical, the information such as size can be identical Or it is different；The textural characteristics that similar image is represented by image file are similar, and the information such as size can not be identical or different.

It is to be appreciated that in other embodiments, step 102 can also be omitted, can directly to all image files into Row texture feature extraction, and according to textural characteristics to determine whether can be using multiple images file as image group.Certainly, due to The filter operation of step 102 can be grouped operation according to the name information of image file, in the filtering of implementation steps 102 Under the premise of operation, the extraction of textural characteristics can carry out in image file ungrouped after filter operation, be conducive to accelerate The processing speed of image grouping.

It is to be appreciated that texture characteristic extracting method may include LBP (Local Binary Pattern, local binary Mode), the step of texture feature extraction of LBP, is as follows:

The zonule (cell) that n*n (such as 16*16) can first be divided an image into, for a pixel in each cell, 8 points (being also possible to the multiple points of annular neighborhood) in its annular neighborhood are subjected to comparison clockwise or counterclockwise, if in Heart pixel value is bigger than the adjoint point, then adjoint point is assigned a value of 1, is otherwise assigned a value of 0, point each in this way can obtain one 8 two into Number (generally also can be exchanged into decimal number) processed.Then the histogram of each cell is calculated, i.e., each number is (it is assumed that the decimal system Number) (namely one carries out about putting a big binary sequence in the whether neighbour domain of each pixel for the frequency that occurs Statistics), then the histogram is normalized.Finally the statistic histogram of obtained each cell is attached, The LBP textural characteristics of whole picture figure have just been obtained, have judged whether it is the same or similar image with the textural characteristics according to image.

It is to be appreciated that when the similarity of at least textural characteristics of two images is greater than preset value, it can be by these images File is as an image group.

For example, when the textural characteristics of the first image group are arrows with rounded corners, by the texture feature extraction of image Afterwards, it is believed that its textural characteristics is identical, thus, it is believed that each image in the first image group is identical image.And when second Include in the textural characteristics of image group arrow with rounded corners with arrow with wedge angle when, due to including arrow in this second image group The textural characteristics of head, difference are fillet or wedge angle, and in some interfaces, these images are can be replaced mutually, thus, It is considered that containing similar image in second group of image.

Step 106, identification operation is carried out according to image file of the recognition rule to described image group, described in being corresponded to The reservation image of image group and it is replaced image.

Preferably, can be according to recognition rule come to obtain one in described image group reservation image and one or more It is replaced image.

Preferably, the recognition rule may include executing identification operation according to the type of image file or according to image file Dimension information execute identification operation.

It is to be appreciated that when executing identification operation according to the type of image file, for the type of image file, Image type be vector image, and vector image can keep identical clarity when scaling different size.Thus, It there are the type information of an image file is vector image if they are the same or in similar image group, then can protect in image group Stay image file type information be vector image, it is and other in same or similar image group are non-to obtain retaining image Vector image replaces with the reservation image, in this way, the image that changes of other non-vectors can be used as institute in same or similar image group It states and is replaced image.

It is to be appreciated that the file for being replaced image can be deleted, and updates in the source file of the application and be replaced image Reference.Preferably, the location information for being replaced image file can be needed to obtain from the preparation file, and figure will be replaced As the location information of file replaces with or be updated to location information corresponding to the image file retained in described image group, such as This, to show or call it is described be replaced image file when, can be shown by the image file of the reservation, wherein showing When the image file of the reservation, phase can be carried out to the image file of the reservation according to the size information for being replaced image file That answers zooms in or out, and zooming in or out for vector image, and for a user, the effect of display has no significantly Difference.

It is to be appreciated that being executed in identification operation according to the dimension information of each image file, if being in image group When non-vector image, then the identification can be executed according to the dimension information of image file and operated.

Preferably, the dimension information for the image file that image group includes can be obtained.For example, an image group may include Sample.png, sample@2x.png, sample@3x.png tri- open image file, wherein image file sample.png, Sample@2x.png, sample@3x.png dimension information may respectively be 30px*30px, 48px*48px, 200px*200px.

Judge in described image group with the presence or absence of an image file by the way that other images into described image group are enlarged Clarity afterwards is not less than default clarity.

Preferably, assuming in image group, reservation image V1 can be replaced other and be replaced image, in this way, can be by comparing Retain image V1 and other are replaced the dimension information between image V2 to be judged.In addition, passing through when retaining image needs When diminution mode becomes to be replaced image, since image file diminution is little to the image of its clarity, for will protect It stays image needs to be directly become when being replaced image by diminution mode, can will be replaced image and directly delete.

For example, the dimension information for retaining image V1 is a1；The dimension information for being replaced image V2 is a2；Definition amplification replacement Rate R=(a2-a1)/a1, wherein a2 is not less than a1, indicates that replacement image needs become to be replaced image by way of amplification. When amplify replacement rate R not within a preset range when, replacement image scaling can be indicated to may when being replaced image file pattern Lead to the decline or improper of its clarity；When amplify replacement rate R be located at preset range (such as 0 to 1) it is interior when, can indicate replace image It zooms to and can guarantee certain clarity when being replaced image file pattern.

It is to be appreciated that judging in image group with the presence or absence of an image file by being enlarged to other images, and put Image may also include that before not less than preset clarity after big operation

Judge in image group with the presence or absence of the identical image file of dimension information；When there are the identical image texts of dimension information When part, same or similar, identical at least two image files of dimension information that indicate in the image group that there are images therefore can will One image file of at least two image files is as reservation image, and other identical image files of dimension information can be used as and be replaced Change image.

When the dimension information of image file each in image group is not identical, can determine whether in image group reference picture be converted by Whether within a preset range to replace amplification replacement rate corresponding when image；When amplifying replacement rate in the preset range, It can retain reference picture file in image group as document retaining, other image files can be then replaced.In other implementations It, also can be without the judgement of identical dimension information in mode.

Preferably, can by preparing in file acquisition image group the smallest image file of dimension information as reference picture, By the image file of other sizes information in image group image as a comparison, judge to be replaced with by reference picture a pair of in image group Within a preset range whether amplification replacement rate when than image.In other embodiments, when in described image group exist at least When two the smallest image files, an image file can be randomly choosed in described at least two the smallest image files as institute State reference paper.

When amplifying replacement rate in the preset range, expression can by it is described replaced with by the reference picture it is described right Than image, therefore, the reference picture can be used as reservation image, and the contrast images then can be used as and be replaced image, so The lesser image file of dimension information in image group can be retained, advantageously reduce the volume of the file after being packaged；It later, can also be after The continuous amplification replacement rate judged when reference picture replaces with other contrast images in image group.

When amplifying replacement rate not in the preset range, after indicating the contrast images by reference picture amplification It may have a certain impact to clarity, still, be obtained after diminution can be passed through by the contrast images due to the reference picture, Thus, can using the reference picture as being replaced image, and return execute it is described by the smallest figure of dimension information in image group As file is as reference picture, and by the image file of other sizes information in image group image as a comparison, wherein the ginseng Examine image and contrast images be it is described by image group except it is described be replaced image in addition to other image files.

Later, whether the quantity that can determine whether documents in image group is 1；When quantity is 1, indicate in described image group Remaining contrast images can be used as retaining image.

In other embodiments, the step of judging image file identical with the presence or absence of dimension information in image group also may be used It omits.For example, when containing the identical image file of two dimension informations in image group, the dimension information for retaining image V1 is A1, the dimension information for being replaced image V2 is a2, according to amplification replacement rate R=(a2-a1)/a1 it is found that R=0.At this point, when putting Big replacement rate R be located at preset range (such as 0 to 1) it is interior when, can indicate to replace image scaling to can when being replaced image file pattern Certain clarity is protected, therefore, can obtain being replaced image V2, and the location information for being replaced image is replaced with reserved graph The location information of picture.

In other embodiments, it can determine whether in described image group with the presence or absence of a reference picture by being enlarged to it Corresponding each amplification replacement rate is not less than preset clarity when his all contrast images.It when it is present, can be by the ginseng Image is examined as the reservation image, and other contrast images are replaced image as described in.When it be not present, then by institute Image file of the image group with full-size information is stated as the reservation image, and other image files are as the quilt Replace image.

For example, for the first image group, sample.png (1 times of figure), sample@2x.png (2 times of figures), sample@ The size of 3x.png (3 times of figures) may respectively be 30px*30px, 44px*44px, 48px*48px.When retaining 1 times of figure, due to 2 Figure can be reached with 1 times of figure by way of scaling again, and having its amplification replacement rate of certain clarity after scaling is (44- 30)/30=0.47 can consider (in other embodiments, to be amplified replacement rate and is also referred to as (44*44- within a preset range 30*30)/30*30=1.15, and preset range at this time then needs to be adjusted correspondingly)；And due to 3 times of figures and 1 times of figure It can be reached by way of scaling, and with certain clarity, (it is (48-30)/30=0.6 that it, which amplifies replacement rate, after scaling It is considered that within a preset range, and the standard of other amplification replacement rates also needs being consistent property)；Therefore, it is possible to protect Staying 1 times of figure is to retain image, and 2 times of figures and 3 times of figures can be carried out as image, i.e., 2 times figures and 3 times of figures are replaced by 1 times of figure Replacement.

For the second image group, sample.png (1 times of figure), sample@2x.png (2 times of figures), sample@3x.png (3 Times scheme) size may respectively be 30px*30px, 44px*44px, 77px*77px.When retaining 1 times of figure, due to 2 times of figures and 1 times Figure can be reached by way of scaling, and have certain clarity after scaling；And after being scaled due to 3 times of figures by 1 times of figure Scaling is lower (it is that (77-30)/30=1.57 can consider not within a preset range that it, which amplifies replacement rate) with clarity, and by 2 times of figures can be reached by way of scaling when being amplified to 3 times of figures (its amplify replacement rate be (77-44)/44=0.75 can recognize For within a preset range), and there is certain clarity after scaling；Therefore, it is possible to retaining 2 times of figures is reservation image, and by 1 times Figure and 3 times of figures are used as and are replaced image, and 1 times of figure obtains after being shunk by 2 times of figures, and the influence to its clarity is not Greatly.

For third image group, sample.png (1 times of figure), sample@2x.png (2 times of figures), sample@3x.png (3 Times scheme) size may respectively be 30px*30px, 44px*44px, 200px*200px.When retaining 2 times of figures, since 1 times of figure can It can be reached by way of scaling by 2 times of figures, and there is certain clarity after scaling, therefore, it is possible to which retaining 2 times of figures is to protect Image is stayed, and 1 times of figure is used as and is replaced image；But 2 times of figures are by way of scaling when reaching 3 times of figures, after scaling The clear degree of 3 times of figures is significantly affected that (it is (200-44)/44=3.54 that it, which amplifies replacement rate, it is believed that it is not default In range), thus, 3 times of figures can also remain in image group, and by 2 times of figures as image is replaced, i.e., image group at this time In contain 3 times of figures.At this point, 3 times in image group are schemed that reservation image can be left (with full-size information), and 1 times of figure And 2 times of figures are used as and are replaced image, and can be replaced by the reservation image.

Step 108, updating location information corresponding to image file will be replaced in image group as reservation image institute Corresponding location information.

For example, due to retaining 1 times of figure, quoting 2 times of figures and 3 in turn, in the source file of application in the first above-mentioned image group The position of times figure can be updated to the path where 1 times of figure.

In the second above-mentioned image group, due to retaining 2 times of figures, 1 times of figure and 3 times of figures are quoted in turn, in the source file of application Position can be updated to 1 times figure where path.

In above-mentioned third image group, due to retaining 3 times of figures, but 1 times of figure and 2 times of figures are used as and are replaced image, in turn, The position that 1 times of figure and 2 times of figures are quoted in the source file of application can be updated to 3 times of paths for scheming place.

Step 110, image-erasing will be replaced in described image group.Pass through the similar diagram of the source file of identification application Piece, can automatic duplicate removal (being replaced image as deleted), can automatically by the reference in engineering be changed to it is after duplicate removal as a result, thus Reach use do not need to do extra work substantially and can facilitate identification similar pictures, reduce the size of application file, reduce The flow of user consumes, while can also be improved the success rate of downloading.

Also referring in Fig. 3 present embodiment, described image processing system 417 may include acquiring unit 710, extract list Member 712, recognition unit 714, replacement unit 716 and filter element 718.

The acquiring unit 710 is used to obtain the attribute information that source file in application includes each image file.

The filter element 718 is used to execute filter operation according to the name information of each image file, to obtain one Or multiple images group, wherein each image group contains the same image of different dimension informations.

It is to be appreciated that the acquiring unit 710 can obtain the name information of several image files, institute from configuration file Filter element 718 is stated for matching to the title of several image files, the difference of the title of image file is if it exists It is specific preset characters (such as above-mentioned 2x, 3x), then can be by these figures of title difference on specific character As being used as an image group.Specifically, the acquiring unit 710 can first obtain the title letter of each image file from preparation file Breath, later, the filter element 718 can remove the preset characters that the name information of image file includes, and judge whether to deposit The identical two or more image files of name information after removing preset characters, and if it exists, can will then remove preset characters Name information is identical described two afterwards or multiple images file is as image group, such as by the image file of corresponding file identification As image group.For example, name information sample.png, the sample@2x.png of image, sample@3x.png and abc@ 2x.jpg is respectively sample.png, sample.png, sample.png and abc.jpg after removing preset characters.Wherein, Sample.png can correspond to the first file identification, and sample@2x.png can correspond to the second file identification, and sample@3x.png can Corresponding third file identification, abc@2x.jpg can correspond to the 4th file identification.Since first is literary to third after removal preset characters The name information of the corresponding image of part mark is sample.png, can be used as same image, and the 4th file identification is schemed The name information of picture is abc.jpg.Therefore, the filter element 718 can be by first to image corresponding to third file identification File is as the first image group.

For this image group, to reduce the volume size after being packaged, wherein one can be only retained in the source file of application Image, to obtain retaining image, and other image files then can be used as and be replaced image, can will also be replaced image from answering It is deleted in source file.For example, above-mentioned image sample.png, sample@2x.png, sample@3x.png can make For an image group, and in three images any one can retain, and other can then be deleted as the file for being replaced image. Certainly, in other embodiments, the image file in described image group also can need to retain wherein one according to realizing.

The extraction unit 712 is used to carry out texture feature extraction to each image file, and by the similar of textural characteristics Degree is greater than two or more described image files of preset value as image group.

It is to be appreciated that the textural characteristics of some image files may be same or similar in the source file of application, but its Image file name has differences, and thus, the filter element 718 is after image file name filter operation, source file In be likely present the same or similar image.Wherein, identical image can be expressed as image file textural characteristics it is identical, The information such as size may be the same or different；The textural characteristics that similar image is represented by image file are similar, and the information such as size can It is not identical or different.

It is to be appreciated that in other embodiments, the function that the filter element 718 executes is omitted, the extraction is single Member 712 directly can carry out texture feature extraction to all image file, and according to textural characteristics to determine whether can will be more A image file is as image group.Certainly, since the filter operation of the filter element 718 can be believed according to the title of image file Breath can be grouped operation, in the processing speed for implementing that image grouping can be accelerated under the premise of filter operation.

For example, the extraction unit 712 passes through image when the textural characteristics of the first image group are arrows with rounded corners Texture feature extraction after, it is believed that its textural characteristics is identical, thus, it is believed that each image in the first image group is identical Image.And when including arrow with rounded corners in the textural characteristics of the second image group and with the arrow of wedge angle, due to this second figure Textural characteristics as in group including arrow, difference is fillet or wedge angle, and in some interfaces, these images are can be with It is replaced mutually, thus, the extraction unit 712 is it is considered that contain similar image in second group of image.

The recognition unit 714 is used to execute identification operation to image group according to recognition rule, to obtain corresponding to the figure As the reservation image organized and it is replaced image.

Preferably, the recognition unit 714 can execute identification operation according to recognition rule, to obtain described image group In a reservation image and one or more be replaced image.

It is to be appreciated that when executing identification operation according to the type of image file, for the type of image file, Image type be vector image, and vector image can keep identical clarity when scaling different size.Thus, It there are the type information of an image file is vector image if they are the same or in similar image group, then described in image group Recognition unit 714 can retain image file type information be vector image, and it is other in same or similar image group are non- Vector image replaces with the reservation image, in this way, other non-vectors can be used as and be replaced to be described in same or similar image group Change image.

It is to be appreciated that the file for being replaced image can be deleted, and updates in the source file of the application and be replaced image Reference.Preferably, the location information for being replaced image file, the unit replacement can be needed to obtain from the preparation file 716 can replace with the location information for being replaced image file in the letter of position corresponding to the image file retained in described image group Breath, and can will be replaced image-erasing in described image group, in this way, to show it is described be replaced image file when, can be by institute The image file of reservation is stated to show, it, can be according to being replaced image file wherein when showing the image file of the reservation Size information zooms in or out the image file of the reservation accordingly, and zooming in or out for vector image, For a user, the effect shown has no apparent difference.

It is to be appreciated that the recognition unit 714 is executing in identification operation according to the dimension information of image file, if figure When as in group being non-vector image, then the identification can be executed according to the dimension information of image file and operated.

Preferably, the acquiring unit 710 can obtain the dimension information for the image file that image group includes.For example, a figure As group may include that sample.png, sample@2x.png, sample@3x.png tri- open image file, wherein image file Sample.png, sample@2x.png, sample@3x.png dimension information may respectively be 30px*30px, 48px*48px, 200px*200px。

The recognition unit 714 is for judging in described image group with the presence or absence of an image file by being enlarged to institute Clarity after stating other images in image group is not less than default clarity.

For example, the dimension information for retaining image V1 is a1, the dimension information for being replaced image V2 is a2；Definition amplification replacement Rate R=(a2-a1)/a1, wherein a2 is not less than a1, indicates that replacement image needs become to be replaced image by way of amplification. When amplify replacement rate R not within a preset range when, replacement image scaling can be indicated to may when being replaced image file pattern Lead to the decline or improper of its clarity；When amplify replacement rate R be located at preset range (such as 0 to 1) it is interior when, can indicate replace image It zooms to and can guarantee certain clarity when being replaced image file pattern.

It is to be appreciated that the recognition unit 714 passes through amplification behaviour with the presence or absence of an image file in judging image group Make to other images, and the preset clarity that is not less than of image also can determine whether to whether there is in image group before after amplifying operation The identical image file of dimension information.

When image file identical there are dimension information, the same or similar, size that indicates in the image group that there are images Identical at least two image files of information, therefore, the recognition unit 714 can will retain the image text of at least two image files Part is as reservation image, and other identical image files of very little information can be used as and be replaced image.

When the dimension information of image file each in image group is not identical, the recognition unit 714 be can determine whether in image group Whether within a preset range reference picture is converted into being replaced amplification replacement rate corresponding when image；When amplification replacement rate is in institute When stating in preset range, it can retain reference picture file in image group as document retaining, other image files can then be made To be replaced image.

Preferably, the recognition unit 714 can be by preparing the smallest image text of dimension information in file acquisition image group Part by the image file of other sizes information in image group image as a comparison, judges to be replaced by reference picture as reference picture Within a preset range whether amplification replacement rate when being changed to a contrast images in image group.In other embodiments, when described There are when at least two the smallest image files in image group, the recognition unit 714 can randomly choose described at least two most An image file is as the reference paper in small image file.

When amplifying replacement rate in the preset range, the recognition unit 714 is replaced described by the reference picture The contrast images are changed to, therefore, the reference picture can be used as reservation image, and using the contrast images as being replaced figure Picture, later, the replacement unit 716 can be replaced image-erasing for described, and it is smaller can so to retain dimension information in image group Image file, advantageously reduce be packaged after file volume；Later, it can also continue to judge that reference picture replaces with image group In other contrast images when amplification replacement rate.

When amplifying replacement rate not in the preset range, after indicating the contrast images by reference picture amplification It may have a certain impact to clarity, still, be obtained after diminution can be passed through by the contrast images due to the reference picture, Thus, the recognition unit 714 can using the reference picture as being replaced image, and return execute it is described by ruler in image group The very little the smallest image file of information is schemed as a comparison as reference picture, and by the image file of other sizes information in image group Picture, wherein the reference picture and contrast images be it is described by image group except it is described be replaced image in addition to other images text Part.

Later, whether the quantity that can determine whether contrast images in image group is 1；When quantity is 1, indicate in described image group Remaining contrast images can be used as retaining image.

In other embodiments, the recognition unit 714 judges in image group with the presence or absence of the identical figure of dimension information As file can also omit.For example, retaining image V1's when containing the identical image file of two dimension informations in image group Dimension information is a1, and the dimension information for being replaced image V2 is a2, according to amplification replacement rate R=(a2-a1)/a1 it is found that R=0. At this point, the judgement of the recognition unit 714 amplification replacement rate R is located in preset range (such as 0 to 1), replacement image scaling can be indicated To that can protect certain clarity when being replaced image file pattern, therefore, the recognition unit 714 can obtain being replaced image V2, and the location information for being replaced image is replaced with to the location information for retaining image.

In other embodiments, the recognition unit 714 can determine whether in described image group with the presence or absence of a reference picture Corresponding each amplification replacement rate is not less than preset clarity when by amplifying operation to other all contrast images.When depositing When, the recognition unit 714 can be using the reference picture as the reservation image, and using other contrast images as institute It states and is replaced image.When it be not present, described image group is then had the image text of full-size information by the recognition unit 714 Part is replaced image described in other image file conducts as the reservation image.

For example, for the first image group, sample.png (1 times of figure), sample@2x.png (2 times of figures), sample@ The size of 3x.png (3 times of figures) may respectively be 30px*30px, 44px*44px, 48px*48px.When retaining 1 times of figure, due to 2 Figure can be reached with 1 times of figure by way of scaling again, and having its amplification replacement rate of certain clarity after scaling is (44- 30)/30=0.47 can consider (in other embodiments, to be amplified replacement rate and is also referred to as (44*44- within a preset range 30*30)/30*30=1.15, and preset range at this time then needs to be adjusted correspondingly)；And due to 3 times of figures and 1 times of figure It can be reached by way of scaling, and with certain clarity, (it is (48-30)/30=0.6 that it, which amplifies replacement rate, after scaling It is considered that within a preset range, and the standard of other amplification replacement rates also needs being consistent property)；Therefore, it is possible to protect Staying 1 times of figure is to retain, and 2 times of figures and 3 times of figures can be replaced as image, i.e., 2 times figures and 3 times of figures are replaced by 1 times of figure.

For third image group, sample.png (1 times of figure), sample@2x.png (2 times of figures), sample@3x.png (3 Times scheme) size may respectively be 30px*30px, 44px*44px, 200px*200px.When retaining 2 times of figures, since 1 times of figure can It can be reached by way of scaling by 2 times of figures, and there is certain clarity after scaling, therefore, it is possible to which retaining 2 times of figures is to protect Image is stayed, and 1 times of figure is used as and is replaced image；But 2 times of figures are by way of scaling when reaching 3 times of figures, 3 after scaling The clear degree of times figure is significantly affected that (it is (200-44)/44=3.54 that it, which amplifies replacement rate, it is believed that it is not in default model In enclosing), thus, 3 times of figures can also remain in image group, and 2 times of figures are used as and are replaced image, i.e., in image group at this time Contain 3 times of figures.At this point, 3 times of figures in image group can retain, and 1 times of figure and 2 times of figures can be used as and are replaced image, and can quilt The reservation image replacement.

The replacement unit 716 replaces image institute for will be replaced the updating location information of image file in image group Corresponding location information.

For example, due to retaining 1 times of figure, the replacement unit 716 can be by the source file of application in the first above-mentioned image group The location information of middle 2 times of figures of reference and 3 times of figures can be updated to the path where 1 times of figure.
