The present application claims priority to Chinese Patent Application No. 202110319497.3 filed in China on Mar. 25, 2021, which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of display technology, and in particular to a color setting method for a display device, a display device, a non-transitory computer readable storage medium, and computer equipment.
Displays, televisions and other screen display products are distributed throughout every corner of our lives. Different brands of display devices have their own style of display-related parameters and databases. The adjustment and judgment criteria of these parameters are usually based on the subjective evaluation of professional picture quality personnel of each company, while the “good-looking” criteria are often the case that everyone has their own aesthetic and judgment, which are different from person to person and cannot be unified. As such, different brands of display devices have different color styles, with some brands having warmer colors, some having cooler colors, some having brighter colors, and the like. For the end user, one may only select brand A if he prefers a bright color, and one may only select brand B if he prefers a cool color, and so forth. It is easy to form the user's inherent feeling towards the brand for a long time. The product style is limited and solidified by the user's awareness, resulting in great limitations of both product and user groups.
Moreover, the existing display device color correction methods are not intuitive, and if the user is not satisfied with factory settings of the picture color of the display device, it is usually necessary to perform cumbersome adjustment of parameters such as numbers, histograms or curves in the setting menu. Ordinary users are unfamiliar with these display parameters, and often keep factory settings without adjustment during use or make the situation worse or less ideal after adjustment due to the lack of understanding of the specific meaning of each parameter, thereby affecting the user's perception and even the user's favorability of the brand.

In order to more clearly explain technical solutions in the embodiments of the present disclosure, a brief description will be given below with reference to the accompanying drawings to be used in the description of the embodiments, and it is obvious that the drawings in the description below are only some embodiments of the present disclosure, and other drawings can be obtained from these drawings by a person skilled in the art without involving any inventive effort.
To more clearly illustrate the present disclosure, a further description of the disclosure is provided below in connection with preferred embodiments and the accompanying drawings. Like parts in the drawings are denoted by the same reference numerals. It is to be understood by persons of ordinary skill in the art that the following detailed description is illustrative and not restrictive, and is not intended to limit the scope of the present disclosure.
It should be noted that references to “having”, “comprising”, “including”, and the like in this disclosure are open-ended meaning that when a module is described as “having”, “comprising”, or “including” a first element, a second element, and/or a third element, it is meant that the module includes additional elements in addition to the first element, second element, and/or third element. Furthermore, the use of ordinal terms such as “first”, “second”, and “third” in the present disclosure is not intended to limit the particular order, but merely to distinguish between the various parts.
In order to solve one of the above problems, as shown in
In the present embodiment, by respectively displaying multiple groups of color pictures on a display device, and setting color parameters of the display device according to color preferences determined by the pictures selected by a user, a user can obtain a required color setting in an intuitive manner, so that the display device has display parameters with adjustable styles, improving adaptability to user requirements, and having a wide application prospect.
In one specific example, as shown in
It should be noted that this disclosure is not intended to limit the number of pictures in each group of color pictures, nor is it intended to limit the number of groups of color pictures displayed on a display device. It will be appreciated that the designer may design the color component categories of the display device, the color component categories included in each group of color pictures, and the adjustable range and grading for each color component as desired.
For example, 2 groups of color pictures A and B may be displayed sequentially on the display device, each group of color pictures including 3 pictures. The color components of each picture in the color picture group A are: brightness, saturation and clarity; the color components of each picture in color picture group B are: contrast and hue. Because each group of color pictures contains 3 pictures, the number of gradations that can be adjusted for each group of color components is 3. As another example, 3 groups of pictures A, B and C may also be displayed sequentially on the display device, each group of pictures likewise including 2 pictures. The color components of each picture in the color picture group A are: brightness and saturation; the color components of each picture in the color picture group B are: clarity and contrast; the color component of each picture in the color picture group C is: hue. Because each group of color pictures contains 2 pictures, the number of gradations adjustable for each group of color components is 2.
It can be seen that the number of groups of pictures does not necessarily define the total dimension of the adjustable color components of the display device, and the number of gradations adjustable for each color component is related to the number of pictures in each group.
Alternatively, the picture contents included in each group of color pictures are the same, and the arrangement is such that the difference on the pictures in each group of pictures only lie in the above color components, so that it is possible to avoid subjective interference factors caused by the user's preference for the content ontology, and thus avoid affecting the accuracy of the subsequent parameter correction.
In order to facilitate the description of specific examples, the following applies: displaying 2 groups of color pictures A and B on a display device, wherein each group of color pictures includes 3 pictures; the color components of each picture in the color picture group A are brightness, saturation and clarity; and the color components of each picture in the color picture group B are contrast and hue.
In S103, the selected picture in each group of color pictures is marked in response to a first operation by the user.
Specifically, the user selects 1 picture in each group of color pictures displayed on the display device, and the selection can be made according to personal preferences after the user browses all the pictures in each group of color pictures. The display device marks the selected picture according to each selection operation of the user.
In S105, the display device acquires the user's color preferences according to the 2 selected pictures and the color components of each picture.
Specifically, the display device acquires color data regarding the user according to a plurality of selected pictures and color components of each picture. For example, the color components of the 3 pictures included in the color picture group A are respectively:
For example, the color components of the 3 pictures included in the color picture group B are respectively:
A user selects a picture A-3 and a picture B-2 respectively in the two displays of the color picture group A and the color picture group B, and according to the corresponding color component in the selected picture, the display device acquires the color effect shown by color preferences regarding the user for the picture A-3 and the picture B-2. Meanwhile, since the color effects of the selected picture A-3 and the picture B-2 respectively correspond to a specific brightness value of 60, a saturation value of 40, a clarity value of 70, a contrast value of 40, and a hue of 10, the display effect represented by each picture corresponds to a specific color component. And accordingly, the display device acquires color data regarding the user, namely, the brightness value of 60, the saturation value of 40, the clarity value of 70, the contrast value of 40 and the color temperature value of 10, and then the display device acquires color preferences regarding the user according to the color data.
In order to further improve the accuracy of the color adjustment of the display device, a preference template is optionally pre-set in the display device, and after acquiring color data regarding the user according to the 2 selected pictures and the color components of each picture, the color data are corrected according to the pre-set preference template and color preferences regarding the user are acquired.
In particular, because of the different nature of the color components, different preference templates are pre-stored in the display device. For example, for color components having specific values for brightness, saturation, clarity, contrast, hue, backlight, gamma, etc., the preference template is set to select a value corresponding to the color component selected by the user. For color components where the color temperature is graded in standard, cool color and warm color, the preference template selects the color wavelength corresponding to the selected one of the standard, cool color and warm color. In addition, for color components distinguished by YES or NO such as noise reduction, color enhancement, or the like, the preference template is set to be ON or OFF.
In addition, as those skilled in the art of ordinary skill in the art based on routine knowledge, the specific form of the above preference template may be, for example, a table form, a bar graph form, a check option form, a slider form, a numerical entry form, etc. to which embodiments of the present disclosure are not limited. On the contrary, one skilled in the art can make various alternatives, modifications and additions.
Of course, the above is merely exemplary, and the variety of color components is not limited to the ranges recited above, nor is the above-recited preference template intended to be limiting, e.g. the preference template may also select a pre-stored fitted curve corresponding to the selected color component.
Further, the display device corrects the color data according to the preset preference template and acquires the user's color preferences. Specifically, according to the preset preference template, the display device corrects the color parameters thereof to be consistent with the color data of the picture A-3 and the picture B-2 selected by the user, for example, a brightness value of 60, a saturation value of 40, a clarity value of 70, a contrast value of 40 and a color temperature value of 10, and acquires color preferences regarding the user.
In S107, the color parameters of the display device are set according to the color preferences. The display device sets the color parameters of the display device as the corrected color data according to the user's color preferences, i.e. the color data obtained after correction based on the preset preference template.
In the above-mentioned manner, by respectively displaying multiple groups of color pictures on a display device, and setting color parameters of the display device according to color preferences determined by a picture selected by a user, personalized setting of color preferences can be provided for the user in an intuitive manner, so that the display device has display parameters with adjustable styles, and the user experience is effectively improved.
In an optional embodiment, considering that the display device itself has original color parameters when displaying each group of color pictures, the preferred picture selected by the user based on the display of the display device possesses not only the effect of the parameters of the picture itself, but also the combined effect of the color parameters of the display device and the color data of the picture.
In order to make the final display effect of the color parameters after the display device is reset consistent with the above-mentioned combined effect, namely, in order to enable a user to obtain a display effect consistent with the color effect seen thereby, acquiring color data regarding the user according to a plurality of selected pictures and color components of each picture further includes: reading color parameters of a display device; and acquiring the user's color data according to the read color parameters of the display device, a plurality of selected pictures and color components of each picture.
Specifically, the color parameters of the display device are read, and according to the read color parameters of the display device, the selected picture A-3 and picture B-2, and the color components of the picture A-3 and picture B-2, the superimposed values of the color components of the selected pictures and the color parameters of the display device are acquired. For example, when the display device displays each group of color pictures A and B, the color parameters are: the brightness value of 50, the saturation value of 50, the clarity value of 70, the contrast value of 40 and the color temperature value of −5. After reading the above-mentioned color parameters of the display device, the acquired color data of the user is, for example: the brightness value of 110, the saturation value of 90, the clarity value of 140, the contrast value of 80 and the color temperature value of 5.
Further, when the color data of the display device is corrected again through the preset preference template, the corrected color data obtained based on the user-selected picture A-3 and picture B-2 is no longer a brightness value of 60, a saturation value of 40, a clarity value of 70, a contrast value of 40, and a color temperature value of 10, but becomes a brightness value of 110, a saturation value of 90, a clarity value of 140, a contrast value of 80, and a color temperature value of 5. Next, in S107, the color parameters of the display device set according to the color preferences are also the corrected color data.
By the above arrangement, when the display device is to be displayed with the corrected color parameters, the display effect obtained is substantially consistent with the effect of a preferred picture that the user has selected from multiple groups of color pictures, further improving the user experience.
In some optional embodiments, in order to simplify the hardware structure of the display device, for example, when the color setting method is applied to a light-weight display device such as head-mounted display equipment, a cell phone, or a tablet computer, it is considered that a remote server performs a part of the setting steps in order to simplify the hardware structure of the display device.
Specifically, the 2 selected pictures and the color components of each picture are uploaded to a remote server so as to acquire color data regarding a user; and the remote server is caused to correct the color data according to the preset preference template to acquire the user's color preferences. Then, the display device sets the color parameters of the display device according to color preferences regarding the user acquired to complete the correction setting of the display parameters of the display device.
In some optional embodiments, before S101, namely, before displaying multiple groups of color pictures respectively according to a pre-set sequence, wherein each group of color pictures includes at least two pictures, and each picture includes at least one color component, the above-mentioned color setting method further includes: displaying a color preference setting option on the display device to provide the user with a choice of whether to set the color preferences. Thus, the display device selects to set the color preferences in response to a second operation by the user, such as clicking “OK”, or cancels the setting the color preferences in response to a third operation by the user, such as clicking “Cancel”.
Further optionally, when the color preferences are selected to set in response to a second operation by the user, the above color setting method further includes: uploading configuration parameters of a display device to a remote server, and downloading multiple groups of color pictures corresponding to the display device from the remote server, so as to match suitable color pictures and optimize color settings for the display device in real time.
Further optionally, in view of the fact that the display device is not always exclusively used by a certain user, the display device could also be able to provide a new user with his or her preferred color display effect when the user is replaced.
Therefore, after displaying the color preference setting option, before selecting to set the color preferences in response to a second operation by the user, the above color setting method further includes the following steps: the display device displays a color restoration setting option, and the display device selects to restore color components in response to a fourth operation by the user, for example, clicking “Restore”, in order to again enter the color setting processes of S101 to S107 shown in
In correspondence with the color setting method of the display device provided by the above embodiment, as shown in
The control circuit 203 is configured to implement actions or processes including: controlling the display circuit 201 to display multiple groups of color pictures respectively according to a pre-set sequence, wherein each group of color pictures includes at least two pictures, and each picture includes at least one color component; marking a selected picture in each group of color pictures through the input circuit 202 in response to a first operation by a user; acquiring color preferences regarding a user according to a plurality of selected pictures and color components of each picture; setting color parameters of the display device according to the color preferences.
It is understood that the display device 200 may be any product or component having a display function such as a cell phone, a tablet computer, a television, a display device, a notebook computer, a wearable device, or a navigator.
In the present embodiment, by setting the display device 200 to respectively display multiple groups of color pictures, and setting the color parameters of the display device 200 according to the color preferences determined by the pictures selected by the user, the user can be provided with personalized setting of the color preferences in an intuitive manner, so that the display device 200 has display parameters with adjustable styles, improves the adaptability to the user's requirements, and has a wide application prospect.
