The embodiment of the application provides a thumbnail display method and equipment, and can solve the problems that image features are lost when color trends are forcibly changed when thumbnails are displayed in the prior art, so that images are distorted, and users cannot easily recognize thumbnail contents.

In a first aspect, an embodiment of the present application provides a thumbnail display method, where the thumbnail display method includes: receiving a thumbnail display instruction, and acquiring an image to be displayed in a thumbnail mode; acquiring the attribute of the image to be subjected to thumbnail display, and determining the reference attribute of the thumbnail display according to the attribute of the image to be subjected to thumbnail display; and performing attribute adjustment on the image to be subjected to thumbnail display according to the reference attribute, and performing thumbnail display on the adjusted image.

The method comprises the steps of determining the reference attribute of the thumbnail display by acquiring the attribute of the image to be subjected to the thumbnail display, adjusting the image according to the reference attribute, so that the image to be subjected to the thumbnail display can be more harmonious as a whole, and compared with the method of adopting a unified mask to enable the image to present a color tendency, the method for adjusting the reference attribute can better keep the characteristics of the image to be subjected to the thumbnail display, is favorable for reducing the distortion degree of the image to be subjected to the thumbnail display, and enables a user to more easily recognize the content of the image to be subjected to the thumbnail display. The attribute of the image may include a cold and warm category of the image, a hue of the image, a saturation of the image, and the like.

With reference to the first aspect, in a first possible implementation manner of the first aspect, the obtaining an attribute of the image to be thumbnail-displayed, and determining a reference attribute of thumbnail-display according to the attribute of the image to be thumbnail-displayed includes: acquiring the cold and warm categories of the image to be displayed in the thumbnail mode; determining hue attribution of a to-be-reduced display image according to the cold and warm categories of the image; and determining the reference hue of the image according to the determined proportion of the hue attributions.

After the cold and warm categories of different images are determined, the hue attribution corresponding to the images is determined according to the cold and warm categories of the images, then the proportion corresponding to the hue attribution is determined according to the hue attribution, and the reference hue of the images is determined according to the proportion. For example, whether an image is in a warm color category or a cool color category or a neutral category may be determined according to colors included in the image. After the cooling and heating categories of the image are determined, the color which mainly contributes to the determination of the cooling and heating categories of the image can be used as the hue attribution of the image. And then calculating hue attributions of different images for statistics to obtain a hue with the densest hue attribution, wherein the hue can be used as a reference hue. The reference hue is screened through the cold and warm categories of the image, so that the determined reference hue can represent the cold and warm tones of the page more effectively and represent more information of the image more accurately.

With reference to the first aspect, in a second possible implementation manner of the first aspect, the step of acquiring an attribute of the image to be thumbnail-displayed and determining a reference attribute of thumbnail-display according to the attribute of the image to be thumbnail-displayed includes: obtaining the hue of the image to be subjected to the thumbnail display, and determining the cold and warm types of the image according to the hue of the image; determining the integral cold and warm tone of the image to be displayed in a thumbnail mode according to the cold and warm categories of the image; and determining the reference hue of the image according to the proportion of the hues corresponding to the whole cold and warm tones.

When the reference attribute of the image to be subjected to the thumbnail display is determined, the reference hue of the image to be subjected to the thumbnail display can be determined according to the cold-warm classification and the hue of the image to be subjected to the thumbnail display. Namely, the cold and warm classifications to which the images belong can be determined according to the hues of the images to be subjected to the thumbnail display, and the number of cold color images and the number of warm color images of the images to be subjected to the thumbnail display can be determined. A large number of categories are selected as the overall cool/warm tones of the images to be thumbnail displayed. And then obtaining the hue corresponding to the whole cold and warm tone, determining the reference hue of the image to be subjected to the thumbnail display according to the distribution of the hue corresponding to the whole cold and warm tone, and performing hue adjustment on the image to be subjected to the thumbnail display according to the reference hue, so that the hues of the image to be subjected to the thumbnail display are closer, the whole harmony of the thumbnail image is improved, the content in the thumbnail cannot be damaged, and the recognizability of a user on the thumbnail is improved.

In one implementation, the determining a reference hue of the image according to a proportion of hues corresponding to the overall cool/warm tone includes: searching the ratio of each hue corresponding to the determined integral cold and warm tone in the image to be displayed in a thumbnail mode according to the determined cold and warm categories; and determining the reference hue of the image according to the hue with larger proportion.

The method comprises the steps of searching for each hue corresponding to the determined cold and warm category in an image to be displayed in a contracted mode, more accurately obtaining the whole hue of the image to be displayed in the contracted mode, searching for the distribution of the corresponding hue according to the determined cold and warm category, namely the whole cold and warm hue, and more accurately determining the reference hue on the whole according to the searched distribution of the corresponding hue. Wherein, the warm colors in the cold and warm categories can comprise red, yellow, brown and other colors, and the cold colors in the cold and warm categories can comprise blue, green, purple and other colors.

In one implementation, the determining a reference hue of the image according to a ratio of hues corresponding to the overall cool/warm tone includes: according to the determined cold and warm categories, searching the proportion of each hue corresponding to the determined integral cold and warm tones in the image corresponding to the determined integral cold and warm tones; and determining the reference hue of the image according to the hue with larger proportion.

After the images are classified according to the cooling and heating categories of the images, the hue distribution corresponding to the integral cooling and heating color tones is searched according to the images corresponding to the integral cooling and heating color tones, and the hue distribution corresponding to the integral cooling and heating color tones is searched according to the searched images corresponding to the integral cooling and heating color tones, so that the reference hue corresponding to the integral cooling and heating color tones can be more accurately obtained. For example, the images to be thumbnail-displayed include 100 images, wherein the image of the cool tone is 60 images, the image of the warm tone is 30 images, and the image of the neutral tone is 10 images. The reference hue of the image to be thumbnail displayed may be determined based on a distribution of hues corresponding to 60 cool-toned images, such as hues corresponding to blue, green, and purple.

In one implementation manner, the step of acquiring the attribute of the image to be thumbnail displayed and determining the reference attribute of the thumbnail display according to the attribute of the image to be thumbnail displayed includes: acquiring the saturation of an image to be subjected to thumbnail display; a reference saturation of the thumbnail display is determined from the distribution of the saturations of the acquired image.

In the thumbnail display method, the image to be subjected to thumbnail display can be adjusted based on the reference hue, the image to be subjected to thumbnail display can also be adjusted based on the reference saturation, or the image to be subjected to thumbnail display can be adjusted through the reference hue and the reference saturation, so that the whole adjusted image is more harmonious and attractive, and the use experience of a user is improved.

Wherein the step of performing attribute adjustment on the image to be thumbnail displayed according to the reference attribute comprises: determining the saturation adjustment amplitude of the image according to the difference between the saturation of the image and the reference saturation; and adjusting the saturation of the image according to the saturation adjusting amplitude. For example, a corresponding relationship between the difference and the adjustment range may be preset, the corresponding adjustment range may be searched for according to the difference, and the saturation of the image may be adjusted according to the searched adjustment range. The corresponding relationship between the difference and the adjustment amplitude may be that the larger the difference is, the larger the adjustment amplitude is, the smaller the difference is, and the smaller the adjustment amplitude is, so that an image with a large difference between the saturation and the reference saturation can be adjusted with more accuracy. Of course, in a feasible implementation manner, the image adjusted according to the reference saturation may further determine a difference of the saturations of the adjacent images, and the saturation of the image may be adjusted according to the difference of the saturations of the adjacent images.

In one implementation manner, the step of acquiring the attribute of the image to be thumbnail displayed and determining the reference attribute of the thumbnail display according to the attribute of the image to be thumbnail displayed includes: obtaining the hue of the image of the page to be displayed in a thumbnail mode, and determining the hue distribution of the image of the page to be displayed in the thumbnail mode; and determining the reference hue of the image according to the hue distribution of the image.

The reference hue of the image is determined based on the distribution of the whole hue of the image to be subjected to the thumbnail display, the reference hue corresponding to the image to be subjected to the thumbnail display can be acquired more quickly, and the image is adjusted according to the whole determined reference hue, so that the whole hue of the image to be subjected to the thumbnail display is closer, the content of the image cannot be damaged, and the identification of a user on the content of the thumbnail displayed image is facilitated.

In order to save the display resources of the thumbnails, the moving state of the thumbnails can be acquired by monitoring the display state of the thumbnails. When a sliding instruction of a user for moving a thumbnail is received, the sliding speed of the thumbnail corresponding to the sliding instruction can be acquired, and when the sliding speed is greater than a predetermined speed, the operation of adjusting the attribute of the image to be thumbnail displayed can be omitted, so that hue adjustment and/or saturation adjustment of the image to be thumbnail displayed can be omitted. When the sliding speed is less than the preset sliding speed, the attribute adjustment of the image to be subjected to the thumbnail display is started, so that a user can observe a more attractive and harmonious display picture, and the user can be facilitated to recognize the content of the thumbnail display.

In one implementation, the step of determining a reference attribute of a thumbnail display according to an attribute of the image to be thumbnail displayed includes: and respectively determining the reference attribute of the image to be subjected to the thumbnail display in each group according to the group information of the image to be subjected to the thumbnail display.

The method is not limited to the above, and the method may further include a search instruction of the image, determine the searched image according to the search instruction, and determine the image to be thumbnail displayed according to the searched image.

The acquired image to be thumbnail displayed may be a full-size image or an image subjected to a predetermined scaling down process. When the image to be thumbnail displayed is subsequently adjusted, the image subjected to the reduction processing of the preset proportion can be directly processed, and the processing of the image subjected to the reduction processing is simpler, so that the display efficiency of the thumbnail can be improved.

The reduced images can be stored in the thumbnail display device in advance, when the images to be thumbnail displayed have a predetermined display sequence, the adjusted images can be calculated according to the thumbnail display method of the present application, and the calculated adjusted images are stored in the thumbnail display device in advance, and when the adjusted images need to be displayed, the pre-stored adjusted images can be directly read. For example, the display order of the pre-stored images may be sorted according to time, sorted according to picture category, or the like.

The reduced images have no fixed display order, for example, when the user displays the images searched according to different keywords, or the searched image database is updated, for example, a new photo is taken, the attribute adjustment processing can be performed on the images to be subjected to thumbnail display in real time according to the thumbnail display instruction, so that the requirements of thumbnail display of images in different scenes can be met.

In step S302, acquiring an attribute of the image to be thumbnail-displayed, and determining a reference attribute of thumbnail-display according to the attribute of the image to be thumbnail-displayed;

in this application, the attribute of the image to be thumbnail-displayed may include a cooling and heating category, a hue, a saturation, or the like of the image, or may also be combined according to two attributes thereof, for example, the cooling and heating category of the image and the hue of the image may be combined to jointly determine a reference attribute for thumbnail-display.

The reference attribute may be one of hues in the image, or may also be a saturation range included in the image. The hue is the primary characteristic of color and is the most accurate standard for distinguishing various colors. The initial base color phases were: red, orange, yellow, green, blue, violet. Other more types of hues can be derived from the combination of base colors.

In one implementation, the implementation of determining the reference hue can be as shown in fig. 4, including:

in step S401, the cooling/heating category of the image to be thumbnail displayed is acquired.

Wherein the cool and warm categories of the image include cool tone, warm tone, and neutral tone. When the cooling and heating type corresponding to each image to be subjected to thumbnail display is determined, the color phase included in each image to be subjected to thumbnail display and the proportion of each included color phase can be acquired.

The cold and warm categories corresponding to each image to be displayed in a thumbnail mode can be determined according to the preset corresponding relation between the hues and the cold and warm scores and the proportion of each hue, namely the scores of the warm tone and the cold tone can be calculated according to the product of the cold and warm scores and the proportion of different hues, and the cold and warm categories of the images can be determined according to the scores.

In step S402, the hue attribution of the image to be thumbnail displayed is determined according to the cooling and heating categories of the image.

After the cold and warm categories of the image are determined, the corresponding colors can be searched according to the cold and warm categories. For example, the color corresponding to the cool color category may include a purple color, a green color, a blue color, and the like, and the hue occupation ratio of the color corresponding to each cool color category in a single image of the cool color category may be searched, and the hue with the largest hue occupation ratio is used as the hue attribution of the image.

For example, when the cool/warm type of an image is determined as the cool type, the ratio of purple, the ratio of blue, the ratio of green, and the like are searched for in the colors corresponding to the cool type, and the cool color having the largest ratio is selected as the hue attribute of the image.

In step S403, a reference hue of the image is determined based on the ratio to which the determined hue belongs.

After determining the hue attributions corresponding to the different images respectively, the hue attribution with the largest proportion can be selected according to the proportion of the hue attributions, and the hue attribution is determined as the reference hue of the image in the page.

In one implementation, the basic attribute of the thumbnail display may be determined according to a cooling and heating classification of an image and a color phase of the image, and specifically, as shown in fig. 5, the method includes:

in step S501, a hue of the image to be thumbnail displayed is obtained, and the cooling and heating category of the image is determined according to the hue of the image.

For example, for an image a to be thumbnail-displayed, hues of X1, X2, X3, X4, and X5 are included, where X1 and X2 are warm hues, and X3, X4, and X5 are cool hues. The cool and warm scores corresponding to each hue in X1, X2, X3, X4 and X5 are Y1, Y2, Y3, Y4 and Y5 respectively, and the proportions corresponding to each hue are Z1, Z2, Z3, Z4 and Z5 respectively, so that the score of the image for the warm color category can be calculated as Y1Z 1+ Y2Z 2, and the score of the cool color category can be calculated as: y3 × Z3+ Y4 × Z4+ Y5 × Z5. And comparing the score of the warm color category with the score of the cold color category, and selecting the category with the larger score as the cold and warm category corresponding to the image.

Or, a dominant hue, that is, a hue with the largest proportion, included in the image may be obtained, and the cool and warm categories corresponding to the image may be determined directly from the dominant hue according to a correspondence between the hue and the cool and warm categories. For example, the dominant hue of an image may be determined to be yellow based on the fact that the yellow proportion of the image exceeds the proportion of the other hues. According to the corresponding relation between the hue and the cold and warm tone, the image can be determined to be the warm color category.

In step S502, the overall cooling and heating tone of the image to be thumbnail displayed is determined according to the cooling and heating category of the image.

After the cold and warm categories of each image to be subjected to the thumbnail display are determined, the number of the cold color categories and the number of the warm color categories of the image to be subjected to the thumbnail display can be obtained, and the cold color categories or the warm color categories with larger number can be obtained as the whole cold and warm tones of the image to be subjected to the thumbnail display by comparing the number of the cold color categories with the number of the warm color categories.

For example, the images to be thumbnail-displayed include 100 images, wherein the number of the images in the cool color category or the cool tone is 60, the number of the images in the warm color category or the warm tone is 30, and the number of the images in the neutral tone is 10. Since the number of images of the cool color category is larger than the number of images of the warm color category and the number of images of the neutral tone, it is determined that the overall cool-warm tone is the cool tone or the cool color category.

In a feasible implementation manner, the contribution weight values of different images to the overall cool and warm tone can be determined according to the positions and the cool and warm degrees of the images in the page to be displayed in a thumbnail mode, the score values corresponding to the cool tone, the warm tone or the neutral tone are calculated by combining the contribution weight values, and the overall cool and warm tone of the image to be displayed in the thumbnail mode is determined according to the calculated score values. For example, the closer the position of an image in a page to be thumbnail-displayed is to the center, the larger contribution weight can be obtained.

In step S503, a reference hue of the image is determined according to a ratio of hues corresponding to the entire cool/warm tone.

After the overall cool/warm tone corresponding to the image to be displayed in a thumbnail manner is determined, the hue corresponding to the overall cool/warm tone can be determined according to the corresponding relationship between the cool/warm tone and the hue. Then, the ratio of the corresponding hue in the image is further determined, and according to the ratio, the hue with larger ratio can be selected as the reference hue of the image.

When the proportion of the hues in the image is determined, the proportion of each hue corresponding to the determined overall cool/warm tone can be searched in the image to be subjected to the thumbnail display. The method comprises the steps of searching for each hue corresponding to the determined cold and warm category in an image to be displayed in a contracted mode, more accurately obtaining the whole hue of the image to be displayed in the contracted mode, searching for the distribution of the corresponding hue according to the determined cold and warm category, namely the whole cold and warm hue, and more accurately determining the reference hue on the whole according to the searched distribution of the corresponding hue. Wherein, the warm color in the cold and warm category can comprise red, yellow, brown and other colors, the cold color in the cold and warm category can comprise blue, green, purple and other colors, and the neutral color can comprise gray, white and other colors.

When the proportion of the hues in the image is determined, or the proportion of each hue corresponding to the determined overall cool/warm tone may be searched for in the image corresponding to the determined overall cool/warm tone. After the images are classified according to the cooling and heating categories of the images, the hue distribution corresponding to the integral cooling and heating color tones is searched according to the images corresponding to the integral cooling and heating color tones, and the hue distribution corresponding to the integral cooling and heating color tones is searched according to the searched images corresponding to the integral cooling and heating color tones, so that the reference hue corresponding to the integral cooling and heating color tones can be more accurately obtained. For example, the images to be thumbnail-displayed include 100 images, wherein the image of the cool tone is 60 images, the image of the warm tone is 30 images, and the image of the neutral tone is 10 images. The hue with a wider distribution can be selected as the reference hue of the image to be thumbnail displayed based on the distribution of hues corresponding to 60 images with cool tone, such as corresponding hues of blue, green, and purple.

Fig. 5 illustrates an implementation process of determining a reference hue of a thumbnail display according to an overall cool-warm tone of an image to be thumbnail displayed and a hue of the image to be thumbnail displayed, but is not limited thereto, and when determining the reference hue of the thumbnail display, a hue of all or part of the image to be thumbnail displayed may also be acquired, and a hue of the image to be thumbnail displayed may be determined according to a distribution of the acquired hues. That is, the reference hue in the screen can be directly determined by the hue distribution information of the image which needs to be thumbnail displayed as a whole, and the reference hue of the screen can be determined more quickly. For example, ten thumbnails are included in the thumbnail display page, and the hue included in all the thumbnails in the page and the size of the distribution range of the included hues may be calculated, that is, the distribution ranges of the same hues in the respective images are summed to obtain the distribution range of each hue in the page, and the hue with the largest distribution range is selected as the reference hue for the thumbnail display.

In one implementation, the attribute of the image to be thumbnail displayed may further include a saturation of the image. The reference saturation of the thumbnail display may be determined from the acquired saturation of the image to be thumbnail displayed. Or, the reference saturation and the reference hue of the thumbnail display can be determined according to the hue, the cold and warm types and the saturation of the image to be thumbnail displayed. Wherein determining the reference inclusion degree may be:

the method comprises the steps of acquiring the saturation of an image to be subjected to thumbnail display, and determining the reference saturation of the thumbnail display according to the distribution of the acquired saturation of the image.

The saturation of the thumbnail can determine the saturation corresponding to each image to be thumbnail displayed according to the preset corresponding relationship between the saturation characteristics and the saturation. After the saturation corresponding to each image to be thumbnail displayed is determined, the saturations with more concentrated number can be selected as the reference saturation according to the distribution of the saturations.

When the more concentrated saturation of quantity is confirmed, the saturation range of preset length can be gradually moved through the saturation range of preset length, the quantity of the confirmed saturation included in the saturation range of preset length in the moving process is detected, and the saturation range of the preset length with more included saturation quantity is selected to serve as the reference saturation.

For example, the value range of the saturation is 0 to 10, the saturation range of the preset length is 2, and it is assumed that the number of the images included in the page to be thumbnail displayed is 6, and the calculated saturations of the respective images are: 8.5, 5.1, 4.5, 3.6, 2.2, 5.4, the saturation range with the step size of 2 may be gradually shifted, when the saturation range is greater than or equal to 3.6 and less than 5.6, four saturation values of 3.6, 4.5, 5.1, 5.4 may be included, the saturation range may be used as the reference saturation of the thumbnail display, or the center point of the saturation range may be used as the reference saturation, and the image to be thumbnail displayed may be adjusted according to the reference saturation.

In step S303, an attribute of the image to be thumbnail displayed is adjusted according to the reference attribute, and the adjusted image is thumbnail displayed.

When the reference attribute is a reference hue, a corresponding filter can be selected according to the difference between the hues of the image and the reference image, and the image is subjected to filtering processing or color mixing processing. Because different images have different differences, the selected filter can be determined or different color mixing schemes can be selected according to the differences between the different images and the reference hue, so as to filter the images.

In an implementation manner, as shown in fig. 6, after a reference hue corresponding to the left image is obtained through calculation processing, differences between each image and the reference image are further determined, and the selected filter, such as an image in the fourth column of the first row and an image in the third column of the third row, may be determined, and a yellow filter may be selected for superposition to process the image; for the image of the third row and the second column, the green tone in the image can be reduced through the toning process. For the image in the fifth row and the fourth column, a warm color filter can be superposed to adjust the image.

In one implementation, when the image to be thumbnail displayed is adjusted according to the reference color, the adjustment amplitude may be gradually changed, and when the consistency of the adjusted color of the image reaches a predetermined ratio, for example, greater than or equal to 90%, the adjustment of the image may be completed.

When the reference attribute is a reference saturation, the saturation adjustment amplitude may be determined according to a difference in saturation between the image to be adjusted and the reference saturation. That is, the larger the difference between the saturation and the reference saturation, the larger the adjustment range, and conversely, the smaller the adjustment range.

For example, if the reference saturation is 5, the saturation of image a is 2.5, and the saturation of image B is 6, the adjustment range of image a is greater than that of image B. The adjustment amplitude of different images is determined, so that the saturation of the whole thumbnail displayed page is more harmonious and attractive. Such as the image in the sixth row and the third column of fig. 5, the image and the saturation can be made to approach the reference saturation by an adjustment that reduces the saturation of the image.

In one implementation, the adjustment range of the saturation of all the images in the page may be gradually increased, that is, the adjustment proportion of the saturation of each image is kept unchanged, and the adjustment value of the saturation is gradually increased, and when the saturation of the images in the page keeps a consistent proportion, for example, whether 90% is greater than a predetermined value, the saturation adjustment is completed. The saturation being consistent may be understood as the saturation value belonging to a saturation range of a predetermined length.

In an implementation scenario, a sliding speed of a thumbnail in a thumbnail display page may also be acquired, and the sliding speed of the thumbnail is compared with a predetermined speed threshold, and if the sliding speed is less than the speed threshold, attribute adjustment, including hue adjustment or saturation adjustment, may be started on the image to be thumbnail displayed. If the sliding speed is greater than the speed threshold, the attribute adjustment of the image to be thumbnail displayed can be stopped. Wherein the speed may be represented by a sliding time of one screen, and the speed threshold may be 150 milliseconds to 250 milliseconds.

By monitoring the display state of the thumbnail, the moving state of the thumbnail can be acquired. When a sliding instruction of a user for moving the thumbnail is received, the sliding speed of the thumbnail corresponding to the sliding instruction can be acquired, and when the sliding speed is greater than a preset speed, the operation of adjusting the attribute of the image to be thumbnail displayed can be avoided, so that hue adjustment and/or saturation adjustment of the image to be thumbnail displayed can be avoided, and system resources can be saved. When the sliding speed is less than the preset sliding speed, the attribute adjustment of the image to be subjected to the thumbnail display is started, so that a user can observe a more attractive and harmonious display picture, and the user can be facilitated to recognize the content of the thumbnail display.

In addition, in some possible implementation manners, when a plurality of image groups are included in the page to be thumbnail-displayed, the reference attribute corresponding to each group may be determined respectively, and the images in the group may be adjusted respectively according to the reference attribute of each group, so that the images in the images of each group displayed in the page are more coordinated, and the adjusted images may effectively enable a user to recognize the image content, and reduce the distortion degree of the images.

Fig. 7 is a schematic diagram of an implementation process of still another thumbnail display provided in the present application, and as shown in fig. 6, the thumbnail display process includes:

in step S701, a thumbnail page is opened.

And opening the thumbnail page to acquire the image to be displayed in a thumbnail mode.

In step S702, the hue attribution of each image is determined according to the cooling and heating type of each image.

The hue attribution corresponding to the image can be calculated according to all colors included in each image and the size of the area corresponding to the colors. According to the coldness or warmth of the color and the size of the area, the coldness value, the warmth value and the neutral color value of the image can be respectively calculated, and the color value with the larger calculated value is selected as the hue attribution of the image.

In step S703, the hue tendency of the thumbnail on the current page is calculated.

According to the calculated hue attribution of each image, the distribution information of the hue can be obtained, and according to the distribution information of the hue, the hue with more dense hue distribution can be selected as the hue tendency of the current page.

In step S704, it is determined whether the consistency ratio of the hue tendencies in the current page is less than a predetermined value. If the consistency ratio of the hue tendencies in the current page is smaller than the predetermined value, the process proceeds to step S705, and if the consistency ratio of the hue tendencies in the current page is larger than the predetermined value, the process proceeds to step S707.

In step S705, the hue tendency occupying the largest percentage is selected as the reference hue.

In step S706, the image is adjusted according to the reference hue, so that the consistency of the adjusted hues of the image is greater than a predetermined value.

In step S707, it is detected whether the consistency of the saturation of the image is greater than a predetermined saturation adjustment threshold, if so, the process proceeds to step S709, and the adjustment of the image is ended, otherwise, the process proceeds to step S708, and the saturation of the image is adjusted so that the consistency of the saturation of the image is greater than the predetermined saturation adjustment threshold.
