Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a schematic flow chart of a drawing method provided in an embodiment of the present application, where the method may be performed by a drawing apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:
For example, the electronic device in the embodiment of the present application may include an electronic device configured with a screen, such as a mobile phone and a tablet computer.
The electronic equipment has a fingerprint identification function, namely a capacitive fingerprint identification sensor is arranged below a screen. The fingerprint identification process comprises fingerprint feature extraction, feature storage and feature comparison. Specifically, when a finger of a user touches a screen, a capacitance value of each pixel point is measured based on a semiconductor capacitor array arranged below the screen, wherein the capacitance value is determined according to the distance between the pixel point and the surface of the finger of the user; and generating current fingerprint information according to the capacitance value of each pixel point, wherein the capacitance values of the fingerprint valley and the fingerprint peak are different. For example, referring to fig. 2, fig. 2 is a schematic diagram of a fingerprint identification device according to an embodiment of the present application, in fig. 2, a semiconductor capacitor array includes 56 × 192 pixel points, and when a user's finger touches a screen, a capacitance value of each pixel point is determined, where the larger the distance between a pixel point and a finger surface is, the smaller the capacitance value of the pixel point is, the smaller the distance between the pixel point and the finger surface is, and the larger the capacitance value of the pixel point is. Based on the characteristics of the fingerprint, the fingerprint has a fingerprint valley and a fingerprint peak, when a user touches the screen with a finger, the distance between the fingerprint peak and a pixel point is small, the distance between the fingerprint valley and the pixel point is large, namely, the capacitance value of the pixel point corresponding to the fingerprint peak is large, and the capacitance value of the pixel point corresponding to the fingerprint valley is small, so that fingerprint characteristics are formed. Optionally, the fingerprint features include a whole feature and a local feature, and the whole feature is a feature of a whole fingerprint grain pattern, and may be, for example, a ring (loop), an arch (arch), a spiral (whorl), or the like; since fingerprints are not continuous, smooth and straight, but rather frequently have breaks, bifurcations or folds, the local features of a fingerprint may be fingerprint nodes such as break points, bifurcations, and turning points.
After the fingerprint features are extracted, the fingerprint features can be stored and compared after being stored, the feature comparison can be directly performed after the fingerprint features are extracted, and the feature comparison can be performed based on the extracted local fingerprint features in the fingerprint extraction process. The characteristic comparison is to compare the extracted fingerprint characteristics with the fingerprint stored in the electronic device in advance, and when the preset matching degree is met, the fingerprint comparison is determined to be successful. Illustratively, ten pieces of fingerprint information of a user a and ten pieces of fingerprint information of a user B are prestored in the electronic device, the acquired fingerprint information of the current user is compared with twenty pieces of fingerprint information prestored one by one, and when a matching degree of one piece of fingerprint information (index finger fingerprint information of the user a) and the fingerprint information of the current user is greater than a threshold value (for example, may be 90%), it is determined that the matching is successful, the current user is the user a, and the input fingerprint information is index finger fingerprint information.
For fingerprint input operations such as fingerprint unlocking, when drawing is performed based on a fingerprint, a certain angle often exists between a finger of a user and a screen. Optionally, partial fingerprint information input by the user on the screen is acquired, wherein the partial fingerprint information is partial fingerprint information close to a fingertip, comparison is performed on the basis of the acquired partial fingerprint information and a pre-stored fingerprint, when a preset matching degree is met, it is determined that the fingerprint comparison is successful, and the fingerprint information input by the user is further determined.
In this embodiment, the electronic device is preset with a corresponding relationship between fingerprint information and colors, where the fingerprint information may correspond to one or more colors, or may not correspond to colors. For example, fingerprint information of a common finger may correspond to a plurality of colors, a less common finger may correspond to one color, or no corresponding color may be set.
In the embodiment, the corresponding relation between the color and the fingerprint information is established, so that the electronic equipment directly calls and inputs the corresponding color when acquiring the fingerprint information, the operation of setting the color by a user during each drawing is omitted, and the drawing process is simplified.
It should be noted that, when it is determined that the fingerprint information corresponds to one color after the fingerprint information is acquired, drawing is performed directly based on the determined color.
And 102, when the fingerprint information corresponds to at least two colors, acquiring a pressure value of the user pressing the screen, and determining a target color according to the pressure value.
When one piece of fingerprint information corresponds to two or more colors, for example, the fingerprint information of the index finger of the user can correspond to three colors of red, green and blue, and the target color required by the user cannot be directly determined. Wherein, the screen below is provided with pressure sensor, can gather the pressure value that the user pressed the screen. The electronic equipment is preset with a corresponding relation between the pressure value and the color, and when the pressure value input by the user is matched with the preset pressure value, the color corresponding to the successfully matched pressure value is determined as the target color. When the pressure value input by the user is within the error range of the preset pressure value, it may be determined that the pressure value input by the user is successfully matched with the preset pressure value. Illustratively, the preset pressure values of the three colors of red, green and blue corresponding to the fingerprint information of the index finger are divided into 3N, 6N and 9N, the error range is ± 1.5N, the pressure value of the fingerprint information input by the index finger of the user is 7N, and the preset pressure value matched with the pressure value input by the user is determined to be 6N. That is, the target color of the fingerprint information input by the index finger of the user is green.
Alternatively, the target color may be determined at an input start point of the drawing operation by the user, for example, before the user inputs a curve, fingerprint information of the user may be acquired at the input start point, the target color may be determined according to the input fingerprint information and a pressure value of the input fingerprint information, and after the target color is determined, the curve may be drawn based on the target color. It should be noted that, in the drawing process after the target color is determined, the pressure value of the touch trajectory input by the user is not collected any more, but the target color is used for drawing.
And 103, drawing according to the target color.
In this embodiment, after the target color is determined, a line of the target color is generated according to a touch curve input by a user. Optionally, drawing according to the target color includes: calling the target color; acquiring a touch track input on a screen by a user based on the fingerprint information; rendering the touch track according to the target color, generating an image line with the target color, and displaying the image line on the screen, wherein the track of the image line is the same as the touch track. Illustratively, when the input touch track is a circular track and the target color is red, a red circular line is generated on the screen. Note that a plurality of image lines input on the screen are retained to form a drawing image.
It should be noted that, the target color may be determined at the starting point of each touch trajectory input, and when the user continuously inputs the same touch trajectory based on the same finger, a line of the target color is generated; in the drawing process, a user can input a plurality of continuous or discontinuous touch tracks based on the fingerprint information, that is, when the user touches the screen again after the finger leaves the screen, drawing is still performed based on the target color until the user switches the target color corresponding to the fingerprint information by outputting the pressure value again. In some embodiments, after drawing according to the target color, the method further comprises: when the staying time of the fingerprint information of the user at any position on the screen is longer than the preset time, re-determining the target color of the fingerprint information according to the pressure value of the user pressing the screen at the position; drawing according to the re-determined target color. In this embodiment, the switching condition of the target color corresponding to the fingerprint information is set as the staying time of the fingerprint information at a certain position in the screen, when the staying time is longer than the preset time, the target color is determined again, and when the staying time is shorter than or equal to the preset time, drawing is continued based on the determined target color of the fingerprint information. Illustratively, in the input process of the touch track, the staying time of the fingerprint information at one point in the screen is longer than the preset time, the target color is switched according to the pressure value input at the staying position, the touch track is continuously input based on the switched target color, and a line of the switched target color is formed, namely, the line before the staying position is the target color before switching, and the line after the staying position is the target color after switching.
For example, the staying time of the finger of the user may also be obtained at the input starting point of the touch track, when the staying time is longer than the preset time, the target color of the finger fingerprint information is determined to be switched, the pressure value of the press of the user on the screen is obtained, and the target color of the fingerprint information is determined again according to the input pressure value. In the embodiment, the switching condition of the target color is set, so that the convenience of switching the colors corresponding to the same fingerprint information is improved, the target color does not need to be determined before the input of each touch track, and the color option operation is simplified.
According to the drawing method provided by the embodiment of the application, fingerprint information input by a user on the screen is obtained, and the color corresponding to the fingerprint information is determined according to the preset corresponding relation between the fingerprint and the color; when the fingerprint information corresponds to at least two colors, acquiring a pressure value of a user pressing the screen, and determining a target color according to the pressure value; and drawing according to the target color. Through adopting above-mentioned scheme, when the colour kind of drawing is greater than ten, perhaps when the user is used to several fingers by oneself, correspond a plurality of colours with a fingerprint information, at the drawing in-process, confirm the target colour through the pressure value of input fingerprint information, draw, can set up the colour according to user's demand is nimble, simplified at the drawing in-process, the selective operation of colour has improved the convenience of drawing.

In this embodiment, the color identification method is not limited.
The color prompt area can be arranged at any position of the screen of the electronic equipment, and can be arranged right above or at the right side of the screen. A plurality of colors corresponding to the fingerprint information are displayed by setting the color prompt area, so that a user is prompted, and the user can conveniently select the required color.
In this embodiment, for a plurality of colors corresponding to each piece of fingerprint information, corresponding pressure ranges are respectively set, exemplarily, the colors corresponding to the fingerprint information are three colors of red, green and blue, the corresponding pressure ranges are 0-3N, 3N-6N and 6N-9N, and there is no overlap between the pressure ranges. And acquiring a pressure value of the fingerprint information input by the user, determining a pressure range to which the pressure value belongs, and further determining a target color. For example, if the pressure value of the fingerprint information input by the user is 4N, the pressure range to which the pressure value belongs is determined to be 3N-6N, and the corresponding target color is determined to be green. In the color prompt area, the green mark is displayed in a distinguishing manner to prompt the user that the target color is green, and the target color can be displayed in an enlarged manner or highlighted, for example. The color corresponding to the current pressure value is determined according to the identification displayed in a distinguishing manner when the user cannot accurately master the input pressure value or forgets the corresponding relation between the color and the pressure range, and the accuracy of target color selection is improved.
