Description

SYSTEM, METHOD, AND APPARATUS FOR COLOR SELECTION

CROSS REFERENCE TO RELATED APPLICATION

[001] The present application is based on and claims the benefits of priority to Chinese Application No. 201510337379.X, filed June 17, 2015, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

[002] The present application relates to methods, apparatus, and systems for color selection.

BACKGROUND

[003] Current color selection technologies mainly include two methods.

Method 1 , as illustrated in Fig. 1 , is selecting a color by entering a value representing the color, i.e., a hexadecimal value corresponding to a legal color name. This method is not useful because most people do not know each color's value. If a user does not enter the precise value corresponding to the desired color, the obtained color can be different. Method 2, as illustrated in Fig. 2, is selecting a color from a color palette. This method can usually be found in mobile phone applications.

However, due to limited screen sizes of mobile devices, a larger number of color options, and a large finger press area size, it can be difficult to accurately select a color of desire without multiple attempts. Thus, the second method can be inefficient and inaccurate due to its complicated operation requirement.

SUMMARY

[004] One aspect of the present disclosure is directed to a method for color selection. The method may be implemented by a processor and a non-transitory computer-readable storage medium that stores a set of instructions that is executable by at least one processor of a computer system to cause the computer system to perform a method for color selection, the method comprising: determining parameters for color selection, the parameters for color selection being associated with at least a first dimension and a second dimension; obtaining, from the

parameters for color selection, a first selected parameter based on a first selection area of the first dimension; generating a second selection area of the second dimension based on the first selected parameter; obtaining, from the parameters for color selection, a second selected parameter based on the second selection area of the second dimension; and displaying a color based on the first and second selected parameters.

[005] Another aspect of the present disclosure is directed to an apparatus for color selection. The apparatus may comprise a memory that stores a set of instructions; and a hardware processor configured to execute the set of instructions to: determine parameters for color selection, the parameters for color selection being associated with at least a first dimension and a second dimension; obtain, from the parameters for color selection, a first selected parameter based on a first selection area of the first dimension; generate a second selection area of the second dimension based on the first selected parameter; obtain, from the parameters for color selection, a second selected parameter based on the second selection area; and display a color based on the first and second selected parameters.

[006] Another aspect of the present disclosure is directed to a non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions which, when executed by a processor of a computer system, cause the computer system to perform a method. The method may comprise determining parameters for color selection, the parameters for color selection being associated with at least a first dimension and a second dimension; obtaining, from the parameters for color selection, a first selected parameter based on a first selection area of the first dimension; generating a second selection area of the second dimension based on the first selected parameter; obtaining, from the parameters for color selection, a second selected parameter based on the second selection area of the second dimension; and displaying a color based on the first and second selected parameters.

DETAILED DESCRIPTION

[018] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments consistent with the present invention do not represent all

implementations consistent with the invention. Instead, they are merely examples of systems and methods consistent with aspects related to the invention as recited in the appended claims.

[019] FIG. 3 is a flow diagram illustrating a method 300 for color selection, according to an exemplary embodiment. The method may be performed by a computer system. The computer system may comprise a processor and a non- transitory computer-readable storage medium storing instructions that, when executed by the processor, perform the steps described below.

[020] At step S1 , the computer system determines N-dimensional parameters for color selection, N being larger than or equal to 2. In some embodiments, the larger number N becomes, the more accurate the color selection can achieve.

[021] At step S2, the computer system obtains a first selected parameter from a first selection area of a first dimension, generates a second selection area of a second dimension based on the first selected parameter, obtains a second selected parameter from the second selection area of the second dimension, generates a third selection area of a third dimension from the second selected parameter . . . and obtains a Nth selected parameter from the Nth selection area of the Nth dimension. That is, the computer system obtains a first selected parameter from a first selection area of a first dimension, generates a second selection area of a second dimension based on the first selected parameter, and recursively repeats the obtaining-generating step until obtaining a Nth selected parameter from a Nth selection area of a Nth dimension. The parameter(s) may be selected by a user.

[022] Since a selection area of a dimension is generated based on a selected parameter of an immediately prior dimension, the generated selection area can be dependent on the selection of the parameter, and can sequentially affect a next obtained parameter from the generated selection area. Thus, a selection of a Xth parameter can determine a range of selection choices for a (X+1 )th parameter, and by recursion, the range of selection choices can be narrowed down. A desired color can be accurately selected at the end. [023] At step S3, the computer system displays a color based on all selected parameters, i.e. from the first to the Nth parameter. With a dimension number N larger than or equal to 2, the user can quickly and accurately select a color.

[024] In some exemplary embodiments, generating the second selection area of the second dimension based on the first selected parameter of step S2 may include generating the second selection area of the second dimension based on the first selected parameter and a first operation by the user. The first operation may be performed in the first selection area. Generating an (A+1 )th selection area of an (A+1 )th dimension from an Ath selected parameter may include generating the (A+1 )th selection area of the (A+1 )th dimension from the Ath selected parameter and a first operation by the user in the Ath selection area. The first operation may include preset operation gestures such as clicking, pressing, swiping, sliding, dragging, or zooming in/out. In one example, the user may press on a part of the Ath selection area and swipe upwards. The operation of swiping upwards may be the first operation. The part of the Ath selection area may indicate a selected Ath parameter, and after the first operation is performed, correspondingly, the (A+1 )th selection area can be generated. When the user selects the Ath parameter, for example, by pressing on a part of the Ath selection area, the (A+ 1 )th selection area may not be generated until an operation, such as swiping upwards in the Ath selection area, is performed by the user. This may prevent unintended operations. For example, even if a user misclicks on a part of a selection area, a next selection area may not be generated until the user performs the preset operation. Thus, the user can still click on or select another part of the selection area before generating the next selection area. For another example, if a user does not want to proceed with a selected parameter on a selection area, the user may just not perform the preset operation. The selection area may stay, and a next selection area may not be generated.

[025] In some exemplary embodiments, step S1 further includes determining, by the computer system, 2-dimensional parameters for color selection. FIG. 4 is a graphical illustration of a 2-dimensional parameters interface for color selection, according to an exemplary embodiment. A first-dimensional parameter of the

2-dimensional parameters is color scheme. A second-dimensional parameter of the 2-dimensional parameters is a combination of saturation and brightness. The two parameters can help users to select colors more efficiently and quickly. The saturation, also known as colorfulness, can refer to an intensity or purity of a color. The saturation may indicate a percentage of grey, from 0%, i.e. , grey, to 100%, i.e., complete saturation.

[026] In some exemplary embodiments, step S1 further includes determining, by the computer system, 3-dimensional parameters for color selection. As illustrated in FIG. 9, a first-dimensional parameter of the 3-dimensional parameters is color scheme, a second-dimensional parameter is saturation, and a third-dimensional parameter is brightness. Alternatively, a first-dimensional parameter is color scheme, a second-dimensional parameter is brightness, and a third-dimensional parameter is saturation. The three parameters can help users to select colors more efficiently and quickly.

[027] FIGs. 5-10 are graphical illustrations of 3-dimensional parameters interfaces, according to an exemplary embodiment. The first parameter may be color scheme, the second parameter may be saturation, and the third parameter may be brightness. A user may keep pressing a finger on a screen throughout steps from FIG. 5 to FIG. 9. As illustrated in FIG. 5, moving the finger left and right in the color scheme selection bar can select the first parameter from the color scheme selection bar in a first dimension. As illustrated in FIG. 6, after selecting the first parameter in the color scheme selection bar and with the finger still pressed on the screen, a second selection area for saturation selection can be triggered to display by dragging the finger upwards. As illustrated in FIG. 7, with the finger still pressed on the screen, moving the finger left and right in the saturation selection bar can select the second parameter from the saturation selection bar in the second dimension. As illustrated in FIG. 8, after selecting the second parameter in the saturation selection bar and with the finger still pressed on the screen, a third selection area for brightness selection can be triggered to display by dragging the finger upwards. As illustrated in FIG. 9, with the finger still pressed on the screen, moving the finger left and right in the brightness selection bar can select the third parameter from the brightness selection bar in the third dimension. As illustrated in FIG. 10, after selecting all three parameters, the user may release the finger from the screen. Thus, the entire process may only take one press by the user and can help the user select a color efficiently and accurately.

[028] In some exemplary embodiments, the selection area(s) can have many different shapes, including rectangle, square, circle, and fan. Examples of the selection area are illustrated in FIGs. 4 to 9. The selection area's shape or size can also be adjusted according to application scenarios, such as a display shape, a display size, or a display content of a display displaying the selection area.

[029] FIGs. 11 and 12 are flow diagrams illustrating another method for color selection, according to an exemplary embodiment. In some exemplary

embodiments, when a boundary of a selection area exceeds a screen boundary displaying the selection area, step S2 further includes steps illustrated in FIG. 11 or 12. FIG . 1 1 includes S21 1 , in which the computer system, instead of displaying an entire first selection area, displays a part of the first selection area, according to a second operation, and S212, in which the computer system obtains a selected parameter from the part of the first selection area. FIG. 12 includes S221 , in which the computer system, instead of displaying an entire second selection area, displays a part of the second selection area, according to a second operation, and S222, in which the computer system obtains a selected parameter from the part of the second selection area.

[030] In another word, S2 may include a first step, in which the computer system switches from displaying an entire selection area to displaying a part of the selection area, according to a second operation. In some exemplary embodiments, the selection area may be displayed on a mobile phone with a limited screen size. If the selection area is fully displayed on the mobile phone, the displayed content may look squeezed and may affect the accuracy of color selection by the user. Thus, when the selection area's boundary exceeds the screen's boundary, the computer system may switch among displaying different parts of the selection area, according to a second operation of the user, such that the user can pick a desired part of the selection area to select the desired color. The second operation may include preset operation gestures such as clicking, pressing, swiping, sliding, dragging, or zooming in/out. The selection area may be a first, a second, or a Nth selection area. For example, on the color scheme selection area illustrated in FIG . 5 or on the saturation selection area illustrated in FIG. 7, sliding left or right on the screen can accordingly select different parts, e.g. a left part or a right part, of the selection area.

[031] S2 may also include a second step, in which the computer system obtains a selected parameter from the part of the selection area. Thus, even with a relatively small display screen, users can still accurately select the desire colors, without decreasing a selection area size or losing any selection area.

[032] In some exemplary embodiments, step S2 may include displaying a selection area with a previous selection area. In one example illustrated in FIG. 9, when a selection area is generated, several previous selection areas can be kept on the same screen, so that the user can adjust selected parameters in any of the displayed selection areas. The selection area may be a first, a second, or a Nth selection area.

[033] In some exemplary embodiments, step S2 may include displaying only a latest selection area. For example, if a mobile phone has a limited screen size for displaying a selection area, the computer system may only display a latest selection area, without displaying a previous selection area. In some embodiments, to allow users to adjust selected parameters, the com puter system may back up to and may only display a previous selection area, according to an operation of the user. Thus, the user can conveniently adjust a previously selected parameter, while the screen area usage is conserved.

[034] In some exemplary embodiments, S2 further includes highlighting a selected parameter. For example, when a mobile phone screen for displaying a selection area has a limited size, the computer system may highlight a selected parameter. FIGs. 5-9 illustrate highlighting selected parameters in selection areas with a halo effect. The selected parameter can also be brightened or labeled. Thus, the user can be reminded of selected parameters to avoid wrong selections. The user can also adjust selection accordingly, if finding a wrong selection.

[035] FIG. 13 is a block diagram illustrating an apparatus 100 for color selection, according to an exemplary embodiment. In some exemplary embodiments, since the selected parameter, the selection area, and the dimension may appear in sequence from 1 to N on a screen, the sequence may be defined by words such as "next," "previous," or "latest." Descriptions of a selected

parameter/selection area/dimension and a next selected parameter/selection area/dimension can be applied to any pair of selected parameters/selection areas/dimensions with the same sequence. Apparatus 100 may comprise:

[036] a first module 1 configured to determine N-dimensional parameters for color selection, N being larger than or equal to 2;

[038] obtaining a selected parameter from a selection area of a dimension;

[039] generating a next selection area of a next dimension based on the selected parameter; and

[040] obtaining a next selected parameter from the next selection area of the next dimension; until obtaining a Nth selected parameter from a Nth selection area of a Nth dimension; and

[041] a third module 3 configured to display a color based on all selected parameters.

[042] Operations of the first to third modules are described above with reference to the method for color selection.

[043] The second module may be further configured to generate the next selection area, or any selection area, based on a first operation by a user.

[044] The first module may be further configured to determine 2-dimensional parameters, including a color scheme parameter and a combination parameter of saturation and brightness, for color selection. [045] The first module may be further configured to determine 3-dimensional parameters, including a color scheme parameter, a saturation parameter, and a brightness parameter, for color selection.

[046] The selection area may be square, rectangular, circular, or fan-shaped.

[047] The second module may be further configured to:

[048] when the selection area boundary exceeds a screen boundary displaying the selection area, display a part of the selection area, according to a second operation by the user; and

[049] obtain the selected parameter from the displayed part of the selection area of the dimension.

[050] The second module may be further configured to:

[051] when the next selection area boundary exceeds a screen boundary displaying the next selection area, display a part of the next selection area, according to a second operation by the user; and

[052] obtain the next selected parameter from the displayed part of the next selection area of the next dimension.

[053] In some exemplary embodiments, the second module may display the next selection area with the selection area on the same screen.

[054] In some exemplary embodiments, the second module may display only a latest selection area on a screen.

[055] In some exemplary embodiments, the second module may highlight selected parameter(s).
