Embodiment
For making that object of the present invention, structure, feature and function thereof are had to further understanding, hereby coordinate embodiment to be described in detail as follows.
Refer to Fig. 2, the functional block diagram of the display 10 that Fig. 2 is the embodiment of the present invention.Display 10 comprises the panel unit 12 and the controller 14 that are electrically connected to each other.Controller 14 drives panel unit 12 show images according to the host side data receiving.When display 10 shows while entering the image of shady place by bright place; user is because the conversion of the light and shade suddenly of its field range; conventionally can be difficult to see clearly part high brightness block icon or other corresponding pattern in dark-coloured background in image; therefore controller 14 can be found out by the gray-scale distribution figure that resolves image the high brightness block icon of this part; and judge whether to need to reduce this block diagram target pixel intensity according to parameters such as pixel quantities, so that the image detail of display 10 can be more clear clearly demarcated.
For instance, what play when display 10 is game picture image, image display from bright outdoor when transferring to dark indoor scene and switching, if indoor scene has the block icon such as light source, the luminance difference of light source and other dark-coloured background can destroy the identification of overall image.Therefore, display 10 of the present invention can be found out the bright block icon in indoor scene automatically, and according to bright its intensity of block diagram target initial value correction (reduction brightness), to also take into account the identification of image detail in highlighting picture brightness contrast.
Refer to Fig. 3 to Fig. 5.Fig. 3 is the gray-scale distribution figure of the display 10 shown images of the embodiment of the present invention, and wherein transverse axis represents the various GTG values of image, and the longitudinal axis represents the quantity that each GTG value distributes in image.Fig. 4 is the curve map that the brightness of the embodiment of the present invention changes, and wherein transverse axis represents the various GTG values of image, and the longitudinal axis represents the intensity of each GTG value.Fig. 5 is the process flow diagram of the image regulating method of the embodiment of the present invention, and the image regulating method shown in Fig. 5 is applicable to the display 10 shown in Fig. 1.
Controller 10 can have analytic unit or adjustment unit (not being shown in figure), the function of adjusting in order to carry out image analysing computer, GTG analysis and pixel.The predeterminable threshold value that is used for judging the reference value of image brilliance and is used for judging pixel quantity of memory body (not being shown in figure) of controller 10, and also store in advance a correction function.First, execution step 500 and step 502, the image that starts display 10 is adjusted function, and relatively image brilliance and reference value of controller 10, starts to judge that image frame is bright scene or dark scene.Image brilliance is during higher than reference value, represents that picture in image, in bright scene, does not need to carry out the adjustment of pixel intensity, as step 504.When image brilliance is lower than reference value, represent that the picture in image is dark scene, need further judge whether to utilize correction function to carry out pixel adjustment.Then, execution step 506, controller 10 produces corresponding gray-scale distribution figure according to show image, and as shown in Figure 3, gray-scale distribution figure can find out the distributed quantity situation of different GTG values.Then, execution step 508 and step 510, by gray-scale distribution figure at least cutting be Z2 between the first interval Z1 and Second Region, and relatively pixel quantity and the threshold value of the first interval Z1.Wherein, the scope definition that GTG value is larger is the first interval Z1, and that GTG value is less is Z2 between Second Region.The present invention separately can be cut into gray-scale distribution figure plural interval, and is the first interval Z1 the section definition of GTG value maximum, in order to find out the high brightness block icon of indoor scene.
The gray-scale distribution figure of image can be cut into two or more intervals, the interval that pixel value is lower represents the dark-coloured background in image, comparison image brilliance described in image regulating method of the present invention and the step 502 of reference value can be according to design requirements, and deciding in its sole discretion is to go to judge whether image brilliance goes to judge that lower than reference value or according to the pixel quantity of Z2 between Second Region whether image brilliance is lower than reference value according to the pixel distribution of Z2 between the first interval Z1 and Second Region.When image brilliance is lower than reference value, represent that image frame is switched to dark indoor scene from bright outdoor scene, the image regulating method that so begins to start this case to obtain optimal brightness adjustment effect between the transfer of different scene of game.In addition, the present invention unrestricted image frame are switched to dark indoor scene from bright outdoor scene, also can only adjust for dark scene picture.
When the pixel quantity of the first interval Z1 is less than threshold value, represent that the area of high brightness block icon is little, little on the impact of overall picture in image, therefore execution step 512, controller 10 does not change the pixel intensity (Luma index) of the first interval Z1.When the pixel quantity of the first interval Z1 is greater than threshold value, represent that high brightness block icon occupies a certain proportion of area in image, therefore execution step 514, controller 10 utilizes correction function to reduce the pixel intensity (Luma index) in the first interval Z1, the contrast difference who slows down by this high brightness icon and dark-coloured background.In addition, no matter also not getting rid of the pixel quantity of the first interval Z1, the present invention how much all performs step 514.Special one carries, and the eigenwert of correction function changes along with the gray-scale distribution difference of image, and for example the pixel intensity in given zone is higher, and the correction of correction function is larger; Pixel intensity in given zone is lower, and the correction of correction function is corresponding minimizing.In Fig. 4, curve C L is the initial pixel brightness before adjusting.If for example, the pixel intensity of the first interval Z1 higher (Luma index is between 8～15), curve C L is revised as curve C L1 by correction function; If for example, the pixel intensity of the first interval Z1 medium (Luma index is between 5～7), curve C L is revised as curve C L2 by correction function; If for example, the pixel intensity of the first interval Z1 lower (Luma index is between 0～4), correction function is revised as curve C L3 by curve C L.
Correction function can be the Serial No. corresponding to the GTG quantity of the first interval Z1, all pixels in the first interval Z1 are deducted respectively the preset value from correction function (Serial No.) by image regulating method, by this intensity of fair curve CL each pixel in the first interval Z1.Or the mode that correction function also can passing ratio converts, reduces its pixel intensity or the corresponding ratiometric conversion separately of each pixel basis of the first interval Z1 by all pixels in the first interval Z1 with same ratio, to reduce respectively whole pixel intensity.The correction of curve C L is determined with its original intensity, and original intensity is higher, revises variation larger; Original intensity is lower, revises variation more slow, as shown in Figure 4.The several methods that the compute mode of correction function can be not limited to enumerate above, looks closely design requirement and determines, and no longer other applicable operating function is illustrated in detail in this.
Image regulating method of the present invention and display can judge whether scene is changed according to the entirety of image or specific region brightness; If scene is switched to darker picture, the gray-scale distribution figure that further analyzes image is to find out the high brightness block icon in dark-coloured background, and the default correction function of foundation reduces the brightness of the respective pixel of high brightness block icon, make that high brightness block icon is unlikely in the dark-coloured background of picture seems dazzling, maintain the show state of dark-coloured background simultaneously, both can maintain the comparison of light and shade between different pattern in image, and also can keep the sharpness of image.Compare prior art, the present invention can effectively promote the picture quality of display, the better market competitiveness of tool.
