In order to better meet the experience requirements of user operation, review and the like, the display screen of the current scanning pen is gradually expanded, and the user has further requirements on the content style displayed in the screen, such as setting the favorite display screen background or font color.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a system and a method for replacing the background and the font color of a scanning pen.
In order to achieve the purpose, the invention adopts the following technical scheme:
a system for changing background and font color of a scanning pen comprises:
a triggering module: the event is used for triggering the change of the background color or the change of the font color by the user;
a color setting module: the device is used for extracting an RGB average value from a color picture acquired by a scanning pen; the color setting module is used for setting the extracted RGB average value as a color value of a background or characters for users to preview, and providing options for users to confirm and quit on a display interface of the scanning pen, when the users select to confirm, the color setting module keeps the current color value of the background or the characters and quits an event of changing the background color or changing the font color of the display interface, when the users select the option to quit, the color setting module discards the current color value of the background or the characters and restores the color value of the background or the characters to the original color value, and then the event of changing the background color or the font color of the display interface is quitted.
The system further comprises a color adjusting module, which is used for displaying an adjusting option on a display interface of the scanning pen after the color setting module sets the RGB average value as the color value of the background or the character, when the user selects to adjust, providing a color adjusting interface for the user, so that the user can adjust the current color value and set the color value adjusted by the user as the color value of the background or the font in real time for the user to preview, and providing options of confirmation, cancellation and quitting for the user on the color adjusting interface; when the user selects and confirms, the color adjusting module keeps the current color value of the background or the characters and quits the background color changing or character color changing event; when the user selects to cancel, the color adjusting module sets the color value of the background or the character as the RGB average value again, and the user starts to adjust again from the RGB average value; when the user selects to quit, the color adjusting module discards the current color value of the background or the character and restores the color value of the background or the character to be the original color value.
The system further comprises a background image setting module, which is used for providing options of setting a background image and directly setting a color value for a user on a display interface of the scanning pen when the user triggers an event of changing the background color, splicing image frames acquired by the scanning pen in sequence when the user selects to set the background image first, setting the spliced image as the background image for the user to preview, and providing options of confirmation and rejection for the user on the display interface of the scanning pen; if the user selects to confirm, the background image setting module reserves the current background image and jumps to the color setting module for the user to set the background color; if the user chooses to discard, the background image setting module restores the background image to the original background image and provides the user with options of continuously setting the background image and directly setting the background color on the display interface of the scanning pen; and if the user selects to directly set the background color, skipping to a color setting module for the user to set the background color, and if the user selects to continue setting the background image, repeating the background image setting process.
The invention also provides a method for replacing the background and the font color by using the scanning pen of the system, which comprises the following specific processes:
s1, triggering an event of changing the background color of the display interface or changing the font color by the user through the trigger module;
s2, the user scans the scanning pen to obtain the picture of the target color, the color setting module extracts the RGB average value of the picture of the target color, sets the RGB average value as the color value of the background or font for the user to preview, and provides the user with the options of confirmation and quit on the display interface of the scanning pen; when the user selects the confirmation, the color setting module retains the current color value of the background or the character and quits the event of replacing the background color of the display interface or the font color, and when the user selects the quitting option, the color setting module discards the current color value of the background or the character and restores the color value of the background or the character to the original color value, and then quits the event of replacing the background color of the display interface or the font color.
Further, in the above method, in step S2, after the color setting module sets the RGB average value as the color value of the background or the text, the color adjusting module displays an adjustment option on the display interface of the scanning pen; when the user selects adjustment, the color adjustment module provides a color adjustment interface for the user, and the user adjusts the current color value on the color adjustment interface; the color adjusting module sets the color value adjusted by the user to be the color value of the background or the font in real time for the user to preview, and provides options of confirmation, cancellation and quitting for the user on a color adjusting interface; when the user selects and confirms, the color adjusting module keeps the current color value of the background or the characters and quits the background color changing or character color changing event; when the user selects to cancel, the color adjusting module sets the color value of the background or the character as the RGB average value again, and the user starts to adjust again from the RGB average value; when the user selects to quit, the color adjusting module discards the current color value of the background or the character and restores the color value of the background or the character to be the original color value.
Further, in the above method, if the event that the user triggers to change the background color is triggered, the background image setting module provides the user with the options of changing the background image first and changing the background color directly on the display interface of the wand; if the user selects to directly change the background color, the background color setting is performed as per step S2; if the user selects to replace the background image first, the user scans the pictures of the cardioscope from top to bottom, from left to right through the scanning pen, the background image setting module splices the scanned picture frames in sequence, and replaces the spliced pictures with the background image for the user to preview, and provides options of confirmation and rejection for the user on the display interface of the scanning pen; if the user selects confirmation, the background image setting module keeps the current background image, and the user continues to set the background color according to the process of the step S2; if the user chooses to discard, the background image setting module restores the background image to the original background image and provides the user with options of continuously setting the background image and directly setting the background color on the display interface of the scanning pen; if the user selects to directly set the background color, the user continues the background color setting in accordance with the process of step S2, and if the user selects to continue the setting of the background map, the above-described process of background map setting is repeated.
The invention has the beneficial effects that: the method is simple to operate, the user can set the color of the cardioscope as the background color or the character color of the display screen of the scanning pen, the functions of the scanning pen are enriched, and the use experience of the user is promoted.
