The following will describe in detail. The numbers of the following examples are not intended to limit the preferred order of the examples.
Referring to fig. 2, fig. 2 is a first flowchart of a display parameter adjusting method according to an embodiment of the application. The specific flow of the display parameter adjustment method provided by the embodiment of the application can be as follows:
101. an image type of an image to be displayed of the display device is determined.
In recent years, display devices having an image display function, such as televisions, computers, projectors, smart phones, and the like, have been widely used, and the demands of users for display effects of these display devices have been increasing. However, in the related art, the display effect of the display device is still poor.
The embodiment of the application provides a method for adjusting display parameters to solve the technical problems.
The image to be displayed refers to an image to be displayed by the display device, and the image to be displayed can be any image or video image. The image type can be obtained according to different image classification basis. For example, the image types may be classified into a person image and a non-person image by whether or not a person is present in the image. For another example, the images may be classified into a person image, a landscape image, a building image, and the like according to the image content.
For example, the display device may perform image recognition on the image to be displayed to determine an image type of the image to be displayed.
102. And determining target display parameters of the corresponding display equipment according to the image type of the image to be displayed and the corresponding relation between the image type and the display parameters of the display equipment.
Wherein the display parameter is used for indicating the picture quality of the display picture of the display device. The display parameters may include display parameters of multiple dimensions such as color temperature, color, brightness, contrast, sharpness, saturation, and the like. Color temperature is the perception of a illuminant or white reflector by the human eye, for example, at 6500, many long-wave colors can be restored and the eye can feel relaxed. Contrast is the ratio of the brightness between the brightest white and darkest black of a bright and dark area in an image, the larger the contrast, the brighter the bright place in the picture, the darker the dark place, the stronger the bright and dark contrast, and the more vivid the image. Brightness refers to the brightness of a picture. Definition refers to the definition degree of each detail shadow and the boundary of each detail shadow, and the higher the definition degree is, the finer the picture is, and the more information can be displayed in the same screen area. Saturation refers to the vividness of a color, also known as purity.
In the embodiment of the application, after the display device determines the image type of the image to be displayed, the target display parameter corresponding to the display device can be determined according to the corresponding relation between the image type and the display parameter of the display device.
103. And adjusting the display parameters of the display device to target display parameters.
For example, in the embodiment of the present application, after determining the target display parameter corresponding to the image to be displayed, the display parameter of the display device may be adjusted to the target display parameter, so that the display device displays the image to be displayed according to the target display parameter.
In particular, the application is not limited by the order of execution of the steps described, as some of the steps may be performed in other orders or concurrently without conflict.
As can be seen from the above, when displaying the image, the application matches the corresponding display parameters according to the image types of the image to be displayed, so that the display device has more pertinence when displaying the images to be displayed of different image types, and the display effect of the display device can be improved.
The method described in the previous examples is described in further detail below by way of example.
Referring to fig. 3, fig. 3 is a second flow chart of a display parameter adjusting method according to an embodiment of the application. The method comprises the following steps:
201. first sample images of a plurality of different image types are acquired, and a plurality of sets of first candidate display parameters are acquired.
The sample image can be selected from standard test images, and can be set by a person skilled in the art according to actual requirements.
In the embodiment of the application, the image type can be obtained according to different image classification bases. For example, the image types may be classified into a person image and a non-person image by whether or not a person is present in the image. For another example, the image may be classified into a person image, a landscape image, a building image, and the like according to the image content.
For example, in the case of classifying images according to image content, the plurality of different image types may include two or more image types of a person image, a landscape image, and a building image.
For example, one person image, one scenic image, and one building image may be acquired as the first sample image, and a plurality of different person images, a plurality of different scenic pictures, and a plurality of different building images may be acquired as the first sample image.
In the embodiment of the application, when a plurality of groups of first candidate display parameters are acquired, a value range corresponding to a display parameter of a preset dimension in the display parameters of a plurality of dimensions of display equipment and a preset step length can be acquired; and determining a plurality of groups of first candidate display parameters according to the display parameters of the preset dimension, the value range and the preset step length.
Wherein the preset dimension may be one or more dimensions. When the preset dimension is one dimension, only one dimension of the display parameters is adjusted, for example, when only the definition of the display picture is adjusted, different values are carried out on the definition of each group of display parameters, and the dimensions of the display parameters except the definition are kept unchanged, so that a plurality of groups of first candidate display parameters are obtained. When the preset dimension is a plurality of dimensions, the plurality of dimensions of the display parameter can be adjusted. For example, when the preset dimension is three dimensions, the definition, contrast and color of the image quality can be adjusted to obtain multiple groups of first candidate display parameters.
The specific process of generating multiple groups of first candidate display parameters under the conditions that the preset dimension is three dimensions and the display parameters of the preset dimension are definition, contrast and color is described as follows:
The definition, contrast and color range of the current display device can be obtained first, the range is determined according to the movement of the display device, and the change step length corresponding to the display parameter of each dimension is set. The step size of the change can be determined by a person skilled in the art according to the actual requirements.
For example, the range of sharpness values is [ a, b ], and the step size is alpha; the value range of the contrast is [ c, d ], and the step length is beta; the range of the color is [ e, f ], and the step length is gamma. That is, the present case may automatically generate a plurality of sets of first candidate display parameters by a computer program according to the above-mentioned value range and step size.
Compared with the prior art, when the image quality of the display picture of the display equipment is optimized, the display parameters are manually adjusted for thousands of times by a debugger, so that the convenience of adjusting the display parameters can be improved under the very complicated condition.
202. And controlling the display device to display the first sample image according to each group of first candidate display parameters to obtain a plurality of first display picture images.
For example, there are 200 first sample images and 10 sets of first candidate display parameters, the display device is controlled to display the 200 first sample images according to each set of first candidate display parameters, so as to obtain 200 first display screen images corresponding to each set of first candidate display parameters, and a total of 2000 first display screen images are obtained because the 200 first sample images are subjected to display processing by a total of 10 sets of first candidate display parameters.
The first display picture image may be obtained through screenshot, for example, when the display device is controlled to display a certain first sample image according to a certain set of first candidate display parameters, the corresponding display picture is screenshot, so as to obtain a first display picture image of the first sample image corresponding to the set of first candidate display parameters. In addition, the first display image may be acquired by other methods, which is not particularly limited herein.
203. And carrying out image quality evaluation on the plurality of first display picture images corresponding to each group of first candidate display parameters to obtain a plurality of first image quality scores corresponding to each group of first candidate display parameters.
For example, image quality evaluation is performed on 200 first display screen images corresponding to each set of first candidate display parameters, so as to obtain 200 first image quality scores corresponding to each set of first candidate display parameters.
The image quality may be evaluated according to an image evaluation model corresponding to an image quality evaluation objective index such as PSNR (Peak Signal to Noise Ratio ), SSIMS (tructure Similarity Image Measurement, structural similarity image metric), bliiinds (BLInd Image Notator using DCT Statistics, image integrity evaluation based on DCT domain statistics), and NIQE (Natural image quality evaluator, natural image quality evaluation).
In one embodiment, when evaluating the image quality, an image evaluation model corresponding to an objective quality index of image quality evaluation may be selected at will according to actual needs, and the image quality evaluation is performed on each first display image to obtain a first image quality score of each first display image, and the image quality evaluation is performed on each first display image through the image evaluation models corresponding to the objective quality indexes of multiple image quality evaluation, and the obtained multiple first image quality scores are weighted and calculated to obtain a weighted first image quality score corresponding to each first display image, and the first target group display parameter is determined from multiple groups of first candidate display parameters in a subsequent process through the weighted first image quality score.
204. And determining a first target group display parameter from the plurality of groups of first candidate display parameters according to a plurality of first image quality scores corresponding to each group of first candidate display parameters.
In the embodiment of the application, the maximum first average value of the plurality of first average values corresponding to the plurality of groups of first candidate display parameters can be determined by calculating the first average value of the plurality of first image quality scores corresponding to each group of first candidate display parameters, and the group of first candidate display parameters corresponding to the maximum first average value is used as the first target group display parameter.
For example, first average values of 200 first image quality scores corresponding to each set of first candidate display parameters are calculated, a largest first average value among 10 first average values corresponding to 10 sets of first candidate display parameters is determined, and a set of first candidate display parameters corresponding to the largest first average value is used as a first target set of display parameters.
205. And generating a corresponding relation between the image type and the display parameters of the display equipment according to the plurality of different image types and the first target group display parameters.
For example, when the plurality of different image types include a person image and a landscape image, the generated image type corresponds to the display parameter of the display device in such a manner that the image type is a correspondence of the person image and the landscape image to the first target group display parameter to which the two image types are commonly applied.
For example, when the plurality of different image types include a person image, a landscape image, and a building image, the correspondence between the generated image type and the display parameter of the display device is a correspondence between the image type and a first target group display parameter to which the person image, the landscape image, and the building image are commonly applied.
206. An image type of an image to be displayed of the display device is determined.
For example, the display device may perform image recognition on the image to be displayed to determine an image type of the image to be displayed.
207. And determining target display parameters of the corresponding display equipment according to the image type of the image to be displayed and the corresponding relation between the image type and the display parameters of the display equipment.
For example, when the person image, the landscape image and the building image correspond to the first target group display parameter, and the image type of the image to be displayed is one of the person image, the landscape image and the building image, the target display parameter is determined to be the first target group display parameter.
208. And adjusting the display parameters of the display device to target display parameters.
For example, if the target display parameter is a first target group display parameter, and the sharpness value in the first target group display parameter is a, the contrast value is B, and the color value is C, the sharpness, contrast, and color values corresponding to the display parameter of the display device are adjusted to the above values.
As can be seen from the above, the present application obtains the first target group display parameters common to the images of the plurality of different image types, and establishes the correspondence between the plurality of different image types and the first target group display parameters. When the display device displays the image to be displayed, if the image type of the image to be displayed is one of the plurality of different image types, the display parameters of the display device can be adjusted to the first target group display parameters. It can be understood that the scheme provided in this embodiment is more universal and can be used for two or more image types, in addition, in this embodiment, a set of first candidate display parameters with the best display effect of the first sample images of the two or more image types is obtained as a target set parameter in multiple sets of first candidate display parameters, so that the display effect of the display device is ensured.
Referring to fig. 4, fig. 4 is a third flow chart of a display parameter adjusting method according to an embodiment of the application. The method comprises the following steps:
301. a second sample image of one image type is acquired, and a plurality of sets of second candidate display parameters are acquired.
The sample image can be selected from standard test images, and can be set by a person skilled in the art according to actual requirements.
In the embodiment of the application, the image type can be obtained according to different image classification bases. For example, the image types may be classified into a person image and a non-person image by whether or not a person is present in the image. For another example, the image may be classified into a person image, a landscape image, a building image, and the like according to the image content.
For example, when images are classified according to image content, image types may be classified into image types such as a person image, a landscape image, and a building image.
In the embodiment of the present application, for example, in the case where images are classified into image types of a person image, a landscape image, a building image, and the like according to image contents, one or more images of any one image type of the person image, the landscape image, and the building image may be acquired as the second sample image.
In the embodiment of the application, when a plurality of groups of second candidate display parameters are acquired, a value range corresponding to a display parameter of a preset dimension in the display parameters of a plurality of dimensions of display equipment and a preset step length can be acquired; and determining a plurality of groups of second candidate display parameters according to the display parameters of the preset dimension, the value range and the preset step length.
Wherein the preset dimension may be one or more dimensions. When the preset dimension is one dimension, only one dimension of the display parameters is adjusted, for example, when only the definition of the display picture is adjusted, different values are carried out on the definition of each group of display parameters, and the dimensions of the display parameters except the definition are kept unchanged, so that a plurality of groups of second candidate display parameters are obtained. When the preset dimension is a plurality of dimensions, the plurality of dimensions of the display parameter can be adjusted. For example, when the preset dimension is three dimensions, the definition, contrast and color of the image quality can be adjusted to obtain multiple groups of second candidate display parameters.
The specific process of generating multiple sets of second candidate display parameters is described with the preset dimensions being three dimensions and the display parameters of the preset dimensions being definition, contrast and color, as follows:
The definition, contrast and color range of the current display device can be obtained first, the range is determined according to the movement of the display device, and the change step length corresponding to the display parameter of each dimension is set. The step size of the change can be determined by a person skilled in the art according to the actual requirements.
For example, the range of sharpness values is [ a, b ], and the step size is alpha; the value range of the contrast is [ c, d ], and the step length is beta; the range of the color is [ e, f ], and the step length is gamma. That is, the scheme can automatically generate a plurality of groups of second candidate display parameters by the computer program according to the value range and the step length.
Compared with the prior art, when the image quality of the display picture of the display equipment is optimized, the display parameters are manually adjusted for thousands of times by a debugger, so that the convenience of adjusting the display parameters can be improved under the very complicated condition.
302. And controlling the display equipment to display the second sample image according to each group of second candidate display parameters to obtain a second display picture image corresponding to each group of second candidate display parameters.
For example, there are 100 second sample images and 8 sets of second candidate display parameters, the display device is controlled to display the 100 second sample images according to each set of second candidate display parameters, so as to obtain 100 second display screen images corresponding to each set of second candidate display parameters, and a total of 800 second display screen images are obtained because the total of 8 sets of second candidate display parameters display the 100 second sample images.
The second display picture image may be obtained through screenshot, for example, when the display device is controlled to display a certain second sample image according to a certain set of second candidate display parameters, the corresponding display picture is screenshot, so as to obtain a second display picture image of the second sample image corresponding to the set of second candidate display parameters. In addition, the second display image may be acquired by other means, and is not particularly limited herein.
303. And carrying out image quality evaluation on the second display picture images corresponding to each group of second candidate display parameters to obtain second image quality scores corresponding to each group of second candidate display parameters.
For example, image quality evaluation is performed on 100 second display screen images corresponding to each set of second candidate display parameters, so as to obtain 100 second image quality scores corresponding to each set of second candidate display parameters.
When the image quality is evaluated, the image quality can be evaluated according to the image evaluation model corresponding to the image quality evaluation objective indexes such as PSNR, SSIMS, BLIINDS, NIQE and the like.
In one embodiment, when evaluating the image quality, an image evaluation model corresponding to an objective quality index of image quality evaluation may be selected at will according to actual needs, and the image quality evaluation is performed on each second display image to obtain a second image quality score of each second display image, and the image quality evaluation is performed on each second display image through the image evaluation models corresponding to the objective quality indexes of multiple image quality evaluation, and the obtained multiple second image quality scores are weighted and calculated to obtain a weighted second image quality score corresponding to each second display image, and the second target group display parameter is determined from multiple groups of second candidate display parameters in a subsequent process through the weighted second image quality score.
304. And determining a second target group display parameter from a plurality of groups of second candidate display parameters according to the second image quality scores corresponding to each group of second candidate display parameters.
For example, if the second sample image includes 1, the obtained second image quality score corresponding to each set of second candidate display parameters is 1, and when determining the second target set of display parameters, the set of second candidate display parameters with the highest obtained second image quality score may be used as the second target set of display parameters.
For another example, if the second sample image includes N, where N is a positive integer greater than 1, the second image quality score corresponding to each set of second candidate display parameters is N, and when determining the second target set of display parameters, the second average value of the N second image quality scores corresponding to each set of second candidate display parameters may be calculated, a maximum second average value of the plurality of second average values corresponding to the plurality of sets of second candidate display parameters is determined, and a set of second candidate display parameters corresponding to the maximum second average value is used as the second target set of display parameters.
305. And generating a corresponding relation between the image type and the display parameters of the display equipment according to the image type of the second sample image and the second target group display parameters.
For example, if the image type of the second sample image is a person image, a correspondence relationship between the person image and the second target group display parameter applicable to the person image is generated.
For example, if the image type of the second sample image is a landscape image, a correspondence relationship between the landscape image and the second target group display parameter applicable to the landscape image is generated.
306. An image type of an image to be displayed of the display device is determined.
For example, the display device may perform image recognition on the image to be displayed to determine an image type of the image to be displayed.
307. And determining target display parameters of the corresponding display equipment according to the image type of the image to be displayed and the corresponding relation between the image type and the display parameters of the display equipment.
For example, if the character image corresponds to the second target group display parameter and the image type of the image to be displayed is the character image, the target display parameter is determined to be the second target group display parameter.
308. And adjusting the display parameters of the display device to target display parameters.
For example, if the target display parameter is a second target group display parameter, and the sharpness value in the second target group display parameter is D, the contrast value is E, and the color value is F, the sharpness, contrast, and color values corresponding to the display parameter of the display device are adjusted to the above values.
As can be seen from the above, the present application obtains the second target group display parameter applicable to the image of a certain image type, and establishes the corresponding relationship between the image type and the second target group display parameter. When the display device displays the image to be displayed, if the image type of the image to be displayed is the image type, the display parameters of the display device are adjusted to the second target group display parameters. When the image is displayed, the corresponding display parameters are matched according to the image types of the image to be displayed, so that the display device has more pertinence when displaying the images to be displayed of different image types, and the display effect of the display device can be improved.
