Abstract: A text image correction method and a corresponding text image correction apparatus. Frequency information of a row-direction cumulative curve used by the method is sensitive to an error between a compensation angle for a tilt angle and a real tilt angle, and the method thus has good robustness. The method can accurately estimate the compensation angle for a tilt angle and correct a tilted text image. The method and apparatus can be applied to scenarios such as image pre-processing, automatic compensation for angles of scanned text images, automatic compensation for tilt angles of mobile phone photos.

Abstract: A payment two-dimensional code secure payment method and system without two-step authentication. The method comprises the following steps: by means of a payment application, producing a first payment two-dimensional code and a second payment two-dimensional code, and alternately displaying the first payment two-dimensional code and the second payment two-dimensional code; respectively identifying the first payment two-dimensional code and the second payment two-dimensional code to acquire complete payment information; sending the complete payment information to a payment centre for verification; when verification is successful, the payment is complete. The present method effectively avoids the property loss incurred by users due to scanning of payment two-dimensional code pictures, and increases payment security.

Abstract: Disclosed are a shadow elimination method and apparatus for a text image, and an electronic device.

Abstract: Disclosed are an image capture scene recognition control method and apparatus and an image capture device. The method comprises the following steps: obtaining a preview image of a current image capture scene collected by an image capture device; extracting a brightness component of the preview image, and obtaining brightness component information of the preview image; obtaining a distribution estimation of the brightness component information and a desired ideal brightness distribution; determining the relative entropy between the distribution estimation of the brightness component information and the desired ideal brightness distribution; according to the relative entropy, determining whether the current image capture scene is a shaded image capture scene; when determined that the current image capture scene is a shaded image capture scene, controlling the image capture device such that the light source of the image capture device compensates the light source in the shaded image capture scene.

Abstract: A method and system for displaying a security risk value of online payment by a color. The method comprises the following steps: obtaining a risk value parameter of an online payment risk value, and allocating a color channel to each risk value parameter; during payment, calculating a brightness value of each color channel according to payment information; and if the brightness value of the color channel is greater than a set security risk value, carrying out payment early warning. According to the method, a security state of the current online payment is displayed by an obvious color, and a security risk can be prompted and warned before the online payment, thereby improving payment security.

Abstract: Disclosed are an instant messenger (IM) method, client and system based on a dynamic image grid, the method comprising: adding an icon and/or a phonetic symbol combination to an image grid input interface, and editing the same to generate dynamic image grid information; selecting one image grid from the image grid input interface, operating an editing sub-unit of the image grid and sequentially adding a unit instruction of the editing sub-unit to a unit instruction list; and repeating the above operation until the editing of the image grid input interface is complete, and sending the unit instruction list. Compared to a traditional IM method, the present invention enables a user to participate in the process of information creation and parsing, thus providing the user with a larger space for imagination and development, and enabling the user to express their feelings in a more enriched and interesting way.

Abstract: Disclosed are an expression curve generating method based on voice input, and an device using the same. The method comprises the following steps: (1) inputting voice, and generating an audio file; (2) selecting expression graph buttons corresponding to a type of expressions from multiple expression graph buttons; (3) dividing the audio file into multiple equal time sections according to a time length, and respectively calculating a corresponding volume of each time section; (4) quantifying the corresponding volumes of the different time sections in the audio file into different volume levels; (5) obtaining expression icons corresponding to the volume level of each time section from a same group of expression icons, generating an expression curve using time as a horizontal axis and the volume level as a vertical axis; and (6) displaying the expression curve formed in step (5).

Abstract: The invention provides a method for a user to input individualized primitive data and equipment and a system. The method comprises the following steps of: detecting an input sequence on user equipment; performing match search on the input sequence to acquire one or more matched local individualized primitive data options; and selecting the matched local individualized primitive data options as candidate options, and displaying the candidate options to the user to select. By the method, the equipment and the system, the defect that only character input and symbol input are supported by a traditional input method is overcome; the input of multiple types of individualized primitive data including pictures, audios/videos, style template user-defined characters and the like is realized by the input method; and the user experience is enhanced.

Abstract: Disclosed in the present invention is a character curve generating method and device thereof. The method comprises the following steps: (1) inputting text information, and the text information comprises m characters; (2) performing voice input to generate an audio file; (3) dividing the audio file into m equal time periods and calculating a corresponding sound volume of each time period; (4) calculating dimension information corresponding to each character in the text information according to the sound volumes of different time periods in the audio file; and (5) changing display sizes of the m characters in the text information according to the dimension information acquired in step (4) to form a character curve. The text curve formed by multiple characters in different font sizes generates a more interesting image and provides more information compared to text information in a single font size in the existing instant communication system.
