Description

Method, device, equipment and storage medium for improving nail painting effect

Technical Field

The invention relates to the technical field of nail art, in particular to a method, a device, equipment and a storage medium for improving nail art painting effect.

Background

The main function of nail-beautifying machine is to draw pattern on the hand, foot nail or artificial nail patch of human body, and the nail-beautifying machine is usually formed from main hardware of computer, microprocessor, ink-jet printer and display, and the pattern used by nail-beautifying machine is stored in the hard disk of computer or other memory capable of being called by computer and microprocessor, and its pattern can be displayed on the display for user to view and select, and can be controlled by its related software so as to implement the function of printing pattern on the hand, foot nail or artificial nail patch of human body.

Usually, thousands or even tens of thousands of colored patterns with different shapes and types are stored in the nail art to meet different aesthetic requirements of pursuing individuation of users. The user's needs are endless, which requires the pattern designer of the manicure machine to continually provide new patterns for the user to select. Each independent pattern is designed according to the shape of a hand, a foot nail or an artificial nail patch of a human body according to a certain proportion, position and size, and can be correspondingly printed on the surface of one hand, foot nail or one artificial nail patch of the human body.

The inventor, when implementing the invention, finds that the application mode of nail art beautifying pattern has serious disadvantages:

nail art patterns are usually obtained by shooting objects, computer painting, manual painting or printed matter scanning, and pattern designers utilize the existing mature and convenient computer image editing tool software to process the obtained original patterns into nail art application patterns with certain rules and then store the patterns in a storage device in the nail art. Because patterns are always sought by users, in order to meet the needs of the users, the patterns are required to be provided as many as possible, the larger the user needs, the more the patterns are, the larger the design amount is, the more complicated and time-consuming the manufacturing process, and the larger the memory space is occupied. The existing nail-beautifying patterns are lack of change, the patterns are all filled in the whole nail surface, the color of the patterns is relatively fixed, the quality of the pattern design completely depends on the aesthetic property of designers, and users can only passively accept the patterns; even if the pattern designer is of a highly specialized level, it is difficult to accurately grasp the different aesthetic needs of many users for nail art. The pictures are generally stored on the SDCard, and after the device is produced, the pictures are fixed to a certain extent and are not modified. In many cases, the user selects a colored drawing pattern and then colored-draws the pattern on the fingernail, and the color difference between the pattern color drawn on the fingernail and the pattern color drawn on the original image is large. Different users have personal preferences on the color of the picture, and when the color of the selected picture is too light or too strong, the color concentration is hopefully adjusted, but the adjustment cannot be realized.

It should be noted that, the manner of improving the nail painting effect according to the embodiment of the present invention may be implemented by a nail printer or a nail lamp, and the present invention is not limited to this.

It should be noted that a pixel is defined as being composed of small tiles of an image, so-called pixels (pixels), which have a specific position and assigned color value, and the color and position of the small tiles determine the appearance of the image. A pixel can be considered to be an indivisible unit or element in the entire image, indivisible meaning that it cannot be cut into smaller units or elements again, which exist as a single color cell. Each dot matrix image contains a certain number of pixels that determine the size of the image to be presented on the screen.

Preferably, the pixel processing comprises: acquiring all pixel points in the nail art picture; and adjusting the RGB value of each pixel point according to the color concentration.

It should be noted that the RGB color scheme is a color standard in the industry, and various colors are obtained by changing three color channels of red (R), green (G), and blue (B) and superimposing them with each other, where RGB represents the colors of the three channels of red, green, and blue, and the standard almost includes all colors that can be perceived by human vision, and is one of the most widely used color systems at present. See table 1.

Red	The necessary parameters; integer type. The values range from 0 to 255, representing the red component of the color.
		Green	The necessary parameters; integer type. The values range from 0 to 255, representing the green component of the color.
Blue	The necessary parameters; integer type. The numerical value ranges from 0 to 255 and represents colorThe blue component of the color.

TABLE 1

It should be noted that, when n is greater than or equal to the number of the pre-stored color densities, for example, the number of the pre-stored color densities is 3, and when pixel processing is performed according to the three pre-stored color densities, 3 or more new pictures can be obtained, which is not limited in the present invention.

In this embodiment, when the user inputs that the nail art picture is selected, the nail art picture may be subjected to pixel processing according to a pre-stored color density, for example, 5 color densities are pre-stored, and when the user selects two nail art pictures, the following operations are performed on each nail art picture, and the pixel processing is performed on the nail art picture according to the 5 color densities, so as to obtain at least 5 new nail art pictures.

Preferably, when the input operation is to select the color density, the pixel processing is performed on the pre-stored nail art picture according to the selected color density, so that the pre-stored nail art picture changes the original color density, including:

It should be noted that, when m is greater than or equal to the number of the pre-stored nail art pictures, for example, the number of the pre-stored nail art pictures is 3, when the three nail art pictures are subjected to pixel processing, 3 or more new pictures can be obtained, which is not limited in the present invention.

In this embodiment, when the user inputs that the color density is selected, pixel processing is performed on each pre-stored nail art picture according to the selected color density, for example, only one pre-stored nail art picture is provided, and one or more new nail art pictures can be obtained after the pixel processing is performed according to the selected color density, which is not limited in this embodiment of the invention.

Preferably, the method further comprises the following steps:

acquiring the selection operation of the user on the new nail art picture;

In this embodiment, a plurality of new patterns can be generated, but all of them are temporary, belong to the process file, and in order to facilitate the user to visually observe the change of the picture and the difference with the original picture, a new picture is generated for printing after the user determines the required new nail pattern. The nail art machine prints on the nail according to the input picture and the printing coordinate, the deeper the color in the picture is, the deeper the printing color is, of course, on different screens, because of the existence of color difference, there will be a certain degree of deviation, for the nail art picture that is not selected, will delete, in order to save the storage space.

The embodiment has the following beneficial effects:
