Fig. 2 is the method flow diagram according to the automatic adjustment page visual characteristic of one aspect of the invention, and is as shown in the figure, in step S201, according at least one visual characteristic value of display page, computation vision characteristic reference value.Particularly; When the user is carrying out internet page when browsing; Subscriber equipment to one or more page displayed take a sample, after the sampling, calculate and write down the visual characteristic value of this page; Wherein, the visual characteristic of the page includes but not limited to brightness, color, contrast, saturation degree and colour temperature.The visual characteristic of each type all has a corresponding visual characteristic value; Such as; After brightness, color, contrast, saturation degree and the colour temperature of the page carried out analytical calculation, can obtain corresponding brightness value, color-values, contrast value, intensity value and color temperature value.Present technique field personnel will be understood that above-mentioned brightness, color, contrast, saturation degree and colour temperature are merely for example; The visual characteristic of other other types existing or that possibly occur from now on is as applicable to the present invention; Also should be included in the protection domain of the present invention, and comprise therewith with way of reference at this.According to the visual characteristic value that is write down, calculate and the corresponding visual characteristic reference value of all types of visual characteristics.
In step S202, calculate the visual characteristic value of the page to be shown.Particularly; Subscriber equipment is treated the visual characteristic value of display page and is calculated, wherein, the said page to be shown be browser will present to the user's and with the different new page of the page of the current browsing of user; It can be that the user changes current page through pulling scroll bar; Also can be through clickable hyperlinks or visit other URL and jump to other pages, can also be just at the page of displaying video, pop-up ad, Flash animation or the like; The visual characteristic of the page includes but not limited to brightness, color, contrast, saturation degree and colour temperature.After browser detects the page to be shown, treat all types of visual characteristic value of display page and calculate.
In step S203, the visual characteristic value and the said visual characteristic reference value of the said page to be shown compared.Particularly, all types of visual characteristic values and the visual characteristic reference value corresponding with it of the said page to be shown compared one by one, that is, brightness value and brightness reference value relatively, color-values and the comparison of color reference value, by that analogy.
In step S204,, the visual characteristic of the said page to be shown is adjusted as the result of said comparison during greater than a threshold value.Particularly; Said comparative result and predetermined threshold value are compared; Wherein, said threshold value is corresponding with all types of visual characteristics, such as; The brightness of the page, color, contrast, saturation degree and colour temperature, corresponding brightness threshold value, color threshold value, contrast threshold, saturation degree threshold value and colour temperature threshold value respectively.When certain type visual characteristic value among the result of said comparison during, then adjust the visual characteristic of the type of the page to be shown, and then show greater than threshold value corresponding with it.
Fig. 3 is the method flow diagram of automatic adjustment page visual characteristic in accordance with a preferred embodiment of the present invention, and is as shown in the figure, in step S301, according to the display element in the page, display page carried out piecemeal, calculates the visual characteristic value of each each piecemeal.Particularly, when the user carrying out internet page when browsing, have different display elements in the page usually, such as picture, Flash, video, literal piece, commercial block etc., visible border is arranged usually between each display element.Subscriber equipment is taken a sample to display page, after the sampling, is that unit carries out piecemeal to the display element in the page with the fundamental block, and wherein the size of fundamental block can preestablish, such as can fundamental block being set at 100 * 100 pixels.Please refer to Fig. 4, Fig. 4 is for carrying out the synoptic diagram of piecemeal, wherein to the display element in the page according to the present invention; Commercial block 401 and literal piece 402 are carried out piecemeal is the example explanation, and the size of commercial block 401 is 800 * 100 pixels, and the size of literal piece 402 is 250 * 100 pixels; The size of fundamental block is set at 100 * 100 pixels, is that commercial block 401 was divided into piece 1 to piece 8 after unit carried out piecemeal to commercial block 401 and literal piece 402 with the fundamental block; I.e. 8 fundamental blocks; Literal piece 402 is divided into piece 9, piece 10 and piece 11, and wherein the size of piece 9 and piece 10 is respectively 1 fundamental block, and the size of piece 11 is 0.5 fundamental block.Method of partition for other big or small pictures, Flash, video, literal piece or chained block is consistent with said method, repeats no more at this.Preferably; In page jump, can detect earlier whether the page to be shown has identical page layout with the previous page after the redirect, such as; A lot of pages are to adopt same web page template to generate in same website; If the layout of the page to be shown and display page is identical, the page to be shown can adopt the partitioned mode of display page, need not to repeat piecemeal.
In addition, can fix the sampling frequency of the page, such as 1 time/second; Also can take a sample according to the changing condition of the page, detecting the page that the user browses such as, browser will change, and then treat display page and take a sample.
Behind page sampling piecemeal, the visual characteristic value of each piecemeal is calculated respectively.For instance; A page has been divided into the N piece, for first piecemeal, calculates brightness value 1, color-values 1, contrast value 1, intensity value 1 and color temperature value 1; For N piecemeal, calculate brightness value N, color-values N, contrast value N, intensity value N and color temperature value N.Wherein, the visual characteristic value is the arithmetic mean value of the visual characteristic value of all pixels in this piecemeal in each piecemeal, for instance; The piecemeal of one 100 * 100 pixel; When calculating the visual characteristic value of this piecemeal,, need the brightness value of these 10000 pixels of statistics such as brightness value; Get the arithmetic mean value after the summation, can obtain the brightness value of this piecemeal.Preferably, can also sample, calculate the visual characteristic value of the arithmetic mean of sampling pixel visual characteristic value, improve counting yield with this as this piecemeal to the pixel of zones of different in the piecemeal.For example, can extract the statistics that 10-20 pixel carries out visual characteristic in each piece.
In step S302, treat display page and carry out piecemeal, the piecemeal in the said page to be shown is corresponding with the piecemeal in the said display page.Particularly, adopt with step S301 in the same partitioned mode treat display page and carry out piecemeal, after the piecemeal completion, the piecemeal in the display page is corresponding with one or more of previous sampling one by one with the piecemeal in the page to be shown.With one of previous sampling display page be example, the piecemeal position in the display page is identical if the page to be shown is with this, then only needs the piecemeal of same position is corresponding; If the page to be shown is different with the piecemeal position in the display page, then the page to be shown is corresponding with the piecemeal in the display page according to certain rule, such as size according to piecemeal coincidence factor in two pages.Please refer to Fig. 5, Fig. 5 is with the corresponding synoptic diagram of piecemeal in piecemeal in the page to be shown and the display page, wherein according to of the present invention; The page 501 to be shown is different with the page layout of display page 502, so the position of piecemeal is also different in two pages, supposes that the size of M piecemeal 5011 in the page 501 to be shown is 100 * 100 pixels; The coordinate of its upper left corner A is (1000; 200), M piecemeal 5011 region are to be covered by S piecemeal 5021 of part and T piecemeal of part 5022 just after corresponding to display page 502; Wherein, The size of S piecemeal 5021 and T piecemeal 5022 is 100 * 100 pixels, and the coordinate of S piecemeal 5021 upper left corner B is (980,200).Through calculating; Can draw in the display page 502 the ratio that overlaps of M piecemeal 5011 in S piecemeal 5021 and T piecemeal 5022 and the page 501 to be shown; Be respectively 80% and 20%, think that then M piecemeal 5011 in the page 501 to be shown is corresponding with S piecemeal 5021 in the display page 502.When the piecemeal in the page to be shown is corresponding with the piecemeal in previous a plurality of display pages of taking a sample, adopt identical method, repeat no more at this.
In step S303, according to the visual characteristic value of piecemeal in the said display page, computation vision characteristic reference value.Particularly, according to one or more visual characteristic value of piecemeal of display page of previous sampling, through weighted calculation visual characteristic reference value.For instance, playing a video in the page that the user browses, constantly respectively this page is being taken a sample at t1, t2, t3, t4 and t5; Suppose that this video is K piecemeal of this page just, the brightness value that calculates t1, t2, t3, t4 and t5 this piecemeal of the moment is L1, L2, L3, L4 and L5, according to these 5 brightness values; The brightness reference value L6 ' that can calculate the t6 next page to be shown of the moment equals w1 * L1+w2 * L2+w3 * L3+w4 * L4+w5 * L5, and wherein, w1, w2, w3, w4 and w5 are respectively the weighting coefficient of L1, L2, L3, L4 and L5; Its size is decided by the correlativity between t1, t2, t3, t4 and the t5 brightness of brightness and t6 this video of the moment of this video constantly, such as, w1=0.05; W2=0.05; W3=0.1, w4=0.25, w5=0.55.If t1, t2, t3, t4, t5 have no correlativity constantly and between the t6 moment page to be shown; Such as; The user is redirect in the different pages frequently, then makes w1=w2=w3=w4=0, w5=1; Promptly only need calculate the visual characteristic reference value of the page to be shown with the previous sampling page of the page to be shown.Present technique field personnel will be understood that above-mentioned sampling number, the sampling moment and weighting coefficient are merely for example, and its concrete numerical value needs set according to actual conditions.
In step S304; Calculate the visual characteristic value of each piecemeal in the said page to be shown, wherein, calculate the method for the visual characteristic value of each piecemeal in the page to be shown; With calculate display page among the step S301 in the method for visual characteristic value of each piecemeal consistent, repeat no more at this.
In step S305, the visual characteristic value and the visual characteristic reference value of each piecemeal in the said page to be shown compared.Particularly, all types of visual characteristic values and the visual characteristic reference value corresponding with it of each piecemeal in the said page to be shown compared one by one, that is, brightness value and brightness reference value relatively, color-values and the comparison of color reference value, by that analogy.
In step S306,,, adjust the visual characteristic of said piecemeal place display element according to the weight of visual characteristic when the comparative result of a certain piecemeal during greater than a threshold value.Particularly,, exist a threshold value corresponding with it for the visual characteristic of each type, such as, brightness, color, contrast, saturation degree and colour temperature be corresponding brightness threshold value, color threshold value, contrast threshold, saturation degree threshold value, colour temperature threshold value respectively.Wherein, threshold value is to determine by the parameter of threshold strategies and user's display device is common.Threshold strategies comprises the Different Strategies based on the different set of age of user, dysopia and/or ambient light;, glaucoma strategy, cataract strategy, strong surround lighting strategy, middle surround lighting strategy, weak surround lighting strategy tactful and do not adjust strategy etc. such as, child strategy, old man; The parameter of user's display device includes but not limited to brightness, color, contrast, saturation degree and colour temperature.Because can there be certain difference in the parameter of different manufacturers display device; So the display effect of the same page on different display devices also exists difference; In order to let the user on different display devices, see same effect; In setting threshold, not only to consider threshold strategies, also to consider the parameter of user's display device.In addition; The parameter of threshold strategies and display device has also been set an initial threshold jointly; Be used for when the user carries out page browsing; Visual characteristic to initial page is carried out rough adjustment, prevent the user when initial browsing pages because the too drastic visual impact that brings of visual characteristic of the page also provides the reasonable reference page for the adjustment of subsequent page simultaneously.Subscriber equipment offers the user with whole threshold strategies and selects according to its demand, such as, the option of setting threshold strategies under browser, the user can manually choose or button click is confirmed.In case the user has confirmed the threshold strategies that it adopted; And combine the parameter of its display device; The corresponding size of yet just having confirmed threshold value is not being changed threshold strategies and more under the situation of switching display, subscriber equipment can be adjusted according to the display element that this threshold value is treated in the display page.Comparative result among the step S305 is compared with corresponding threshold value one by one; When the comparative result of a certain piecemeal during greater than its corresponding threshold; Then the visual characteristic of this piecemeal place display element is adjusted; Such as, in the page to be shown between the brightness calculation value of H piece piecemeal and the brightness reference value absolute value of difference explain then in the page to be shown that greater than the luminance threshold in the threshold strategies contrast that H piecemeal compare the previous page is excessive; Possibly cross brightly or dark excessively, need carry out the adjustment of visual characteristic it.Behind the piecemeal that in having confirmed the page to be shown, needs to regulate; Display element to this piecemeal place carries out integrally-regulated; Guaranteed that not only the page to be shown can not impact because of the excessive vision to the user of contrast; Also avoided making the display element demonstration undesired owing to adjusting certain piecemeal separately, the experience when causing user's browsing pages is not good.Because dissimilar visual characteristics is different to the influence degree of user's visual effect; So in the adjustment visual characteristic; All there is the weight of an adjustment in the visual characteristic of each type, i.e. the size of setting range, and the size of weight is relevant with the degree that it influences user's visual effect; Such as; The influence of visual effect when brightness, color and contrast are watched the page to the user is bigger, so in the adjustment visual characteristic, and relatively can be big to the scope of the adjustment of brightness, color and contrast.After according to the weight of each type visual characteristic display element being adjusted, can the page to be shown be presented to the user.Preferably; After the page to be shown is presented to the user, if the user can also continue this page is adjusted at the time long enough that this page stops; Progressively recover the initial visual characteristic of this page; Thus one, the user can progressively adapt in the visual characteristic of gradual change, can not receive the excessive visual impact that brings of contrast.
Preferably, the user can select a plurality of threshold strategies to limit threshold value jointly when selecting threshold strategies simultaneously, the visual characteristic of the page is adjusted according to this threshold value after, can present best display effect to the user.For instance, the user is a child, when it during browsing pages, can select child's strategy and weak surround lighting strategy in the more weak environment of light; When its in the stronger environment of light during browsing pages; Then can select child's strategy and strong surround lighting strategy; Thus one, the adjustment of page visual characteristic not only meets children's demand, can also do adjustment further according to external environment; For the developmental children that grow up, protected its eyesight effectively.
Preferably, subscriber equipment can present best display effect to the user according to automatically for the user adjusts threshold strategies.For instance, the network equipment can be according to user's information, and such as user's IP address, the orientation at consumer positioning place, and then according to time of customer access network is inferred through calculating the lighting condition that user this moment belongs to the light in orientation.The network equipment is sent to subscriber equipment with this result, and subscriber equipment is adjusted strong surround lighting strategy, middle surround lighting strategy or weak surround lighting strategy automatically according to this result.Perhaps, subscriber equipment detects the personal information that the user logins in the page, finds that this user is teenage user, then is adjusted into child's strategy for this user automatically.If subscriber equipment has camera or sensor devices, then can also be that the user selects suitable adjustment strategy automatically according to the surround lighting parameter of camera or sensor devices acquisition.
Preferably, the preference of recording user visual characteristic is treated the visual characteristic of display page and is adjusted according to said preference.The certain user often has its oneself preference when carrying out page browsing, such as; Like the dark partially page of brightness, perhaps like the warm partially page of color, subscriber equipment can carry out record to its preference; Such as, under browser, set the adjustment item of visual characteristic value, the mode that the user can be through pulling scroll bar or input value is adjusted to the state of oneself liking with the visual characteristic of the page; After preserving user's preference, subscriber equipment is adjusted the visual characteristic of the page for the user according to this preference.For instance; The span of supposing brightness is 0～255, and the user is adjusted to 100 according to the preference of oneself with brightness value; Subscriber equipment can distribute according to certain function; Like normal distribution, choosing one, to equal 100 with brightness value be the brightness section at center, and the brightness of the adjustment page that the user browsed all is distributed in this interval.Undistorted in order to ensure the page; Can full luminance interval (0～255) be mapped in the brightness section of user preference; Make that the pixel of the different brightness in the former page still can be distinguished in the user preference luminance area; The preference that not only meets the user is also presented to the user with the page without distortion, and is particularly important for video, picture.Preference for other visual characteristics such as color, contrast, saturation degree and colour temperatures also is so, repeats no more at this.
Preferably, the user name with the user is associated with its selected threshold strategies.When the user passes through the mode accession page of login; Subscriber equipment can be through network with user's information and be stored in its selected threshold strategies in the server in advance; As user once more during the sign-on access page; The user profile that the subscriber equipment basis is obtained from the webserver, such as user name, the setting value when automatically threshold strategies being adjusted to user's last login.
Fig. 6 is the equipment synoptic diagram of automatic adjustment page visual characteristic according to a further aspect of the present invention, and is as shown in the figure, and this subscriber equipment 2 comprises detecting unit 601, computing unit 602, comparing unit 603 and adjustment unit 604.
Wherein, detecting unit 601 is used to detect the display page and the page to be shown.Particularly, when the user is carrying out internet page when browsing, 601 pairs of detecting units display page and the page to be shown are taken a sample; Wherein, The said page to be shown be browser will present to the user's and with the different new page of the page of the current browsing of user, can be the user change current page through pulling scroll bar for it, also can be through clickable hyperlinks or visit other URL and jump to other pages; Can also be just at the page of displaying video, or the like.
Comparing unit 603 is used for the visual characteristic value of the said page to be shown and said visual characteristic reference value are compared.Particularly, comparing unit 603 compares all types of visual characteristic values and the visual characteristic reference value corresponding with it of the said page to be shown one by one; And said comparative result and predetermined threshold value compared; Wherein, said threshold value is corresponding with all types of visual characteristics, such as; The brightness of the page, color, contrast, saturation degree and colour temperature, corresponding brightness threshold value, color threshold value, contrast threshold, saturation degree threshold value and colour temperature threshold value respectively.
When adjustment unit 604 is used for result when said comparison greater than a threshold value, the visual characteristic of the said page to be shown is adjusted.Particularly, when certain type visual characteristic value among the result of said comparison during greater than threshold value corresponding with it, the visual characteristic of the type of the adjustment unit 604 adjustment page to be shown is delivered to display device with the page to be shown then and is shown.
Detecting unit 601 further can also comprise branch module unit (not shown), is used for according to the display element in the page, and display page is carried out piecemeal, is calculated the visual characteristic value of each piecemeal then by computing unit 602.Particularly, when the user carrying out internet page when browsing, have different display elements in the page usually; Such as picture, Flash, video, literal piece, commercial block etc.; 601 pairs of detecting units display page are taken a sample, and after the sampling, are that unit carries out piecemeal to the display element in the page with the fundamental block; Wherein the size of fundamental block can preestablish, such as can fundamental block being set at 100 * 100 pixels.Please refer to Fig. 4, Fig. 4 is for carrying out the synoptic diagram of piecemeal, wherein to the display element in the page according to the present invention; Commercial block 401 and literal piece 402 are carried out piecemeal is the example explanation, and the size of commercial block 401 is 800 * 100 pixels, and the size of literal piece 402 is 250 * 100 pixels; The size of fundamental block is set at 100 * 100 pixels, is that commercial block 401 was divided into piece 1 to piece 8 after unit carried out piecemeal to commercial block 401 and literal piece 402 with the fundamental block; I.e. 8 fundamental blocks; Literal piece 402 is divided into piece 9, piece 10 and piece 11, and wherein the size of piece 9 and piece 10 is respectively 1 fundamental block, and the size of piece 11 is 0.5 fundamental block.Method of partition for other big or small pictures, Flash, video, literal piece or chained block is consistent with said method, repeats no more at this.Preferably; In page jump, whether the page to be shown had identical page layout with the previous page after detecting unit 601 can detect redirect earlier, such as; A lot of pages are to adopt same web page template to generate in same website; If the layout of the page to be shown and display page is identical, the page to be shown can adopt the partitioned mode of display page, divides module unit to need not to repeat piecemeal.
In addition, the sampling frequency of 601 pairs of pages of detecting unit can be fixed, such as 1 time/second; Also can take a sample according to the changing condition of the page, detecting the page that the user browses such as, browser will change, and then detecting unit 601 is treated display page and taken a sample.
Behind page sampling piecemeal, computing unit 602 calculates respectively the visual characteristic value of each piecemeal.For instance; A page has been divided into the N piece, for first piecemeal, calculates brightness value 1, color-values 1, contrast value 1, intensity value 1 and color temperature value 1; For N piecemeal, calculate brightness value N, color-values N, contrast value N, intensity value N and color temperature value N.Wherein, the visual characteristic value is the arithmetic mean value of the visual characteristic value of all pixels in this piecemeal in each piecemeal, for instance; The piecemeal of one 100 * 100 pixel; When calculating the visual characteristic value of this piecemeal,, need the brightness value of these 10000 pixels of statistics such as brightness value; Get the arithmetic mean value after the summation, can obtain the brightness value of this piecemeal.Preferably, can also sample, calculate the visual characteristic value of the arithmetic mean of sampling pixel visual characteristic value, improve counting yield with this as this piecemeal to the pixel of zones of different in the piecemeal.
