It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, when the cursor key is pressed, the camera of the mobile terminal is started to capture the information in front of the camera, and the picture including the captured information in front of the camera is recognized as a keyword text, and is searched in the phrase library and Content corresponding to the keyword text, outputting the searched content corresponding to the keyword text.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

FIG. 1 shows a flow chart of a fast content search method applied to a mobile terminal provided by the first embodiment of the present invention, which is described in detail as follows:

Step S11, when the cursor key is pressed, start the camera of the mobile terminal to capture the information in front of the camera, the cursor key is set on the mobile terminal.

Wherein, as shown in FIG. 2 , the cursor keys can be arranged on the left side of the mobile terminal. Of course, the cursor keys can also be arranged on the right side, upper side or lower side of the mobile terminal, etc.

When the mobile terminal is in the off-screen state, in order to avoid affecting the user's learning by starting other APPs due to the start-up of the entire mobile terminal, when the cursor key is pressed, the mobile terminal is still in the off-screen state, but the camera of the mobile terminal is started in the background quickly Run, and automatically capture images through the auto-focus function.

Optionally, in order to improve the accuracy of capturing information and to facilitate capturing pictures in a screen-off state, before starting the camera of the mobile terminal to capture the information in front of the camera, it includes:

The cursor is activated to emit a cursor point through the activated cursor and a cursor hole, the cursor point is projected on the information in front of the camera, and the cursor hole is arranged on the mobile terminal. The cursor here includes an LED light cursor, wherein the distance between the cursor hole and the camera of the mobile terminal is less than a preset installation distance. Since the distance between the cursor hole and the camera of the mobile terminal is less than the preset installation distance, the information projected by the cursor point is basically the same as the information captured by the camera, and the user can know it through the cursor point projected on the information in front of the camera Information captured by the camera.

At this point, the information in front of the camera captured by the camera of the mobile terminal is specifically:

Said starting the camera of the mobile terminal captures the information around the cursor point in front of the camera. Since the distance between the cursor hole and the camera of the mobile terminal is less than the preset installation distance, the information captured by the camera is information around the cursor point.

Optionally, the starting of the camera of the mobile terminal to capture information around the cursor point in front of the camera specifically includes:

A1. Obtain the shape of the sent cursor point. Wherein, the shape of the cursor point includes: cross, square, circle and other shapes.

A2. Start the camera of the mobile terminal according to the acquired shape of the cursor point to capture the corresponding information around the cursor point in front of the camera, and the camera of the mobile terminal to capture the corresponding information around the cursor point in front of the camera includes: Vocabulary, test questions, Chinese words and sentences. When the shape of the cursor point is different, start the camera of the mobile terminal to capture different information around the cursor point in front of the camera, for example, when the shape of the cursor point is a cross, start the camera of the mobile terminal to capture the surrounding area of the cursor point in front of the camera When the shape of the cursor point is circular, start the camera of the mobile terminal to capture the Chinese words and sentences around the cursor point in front of the camera; when the shape of the cursor point is square, start the camera of the mobile terminal to capture the cursor in front of the camera Point around the words.

Optionally, since words, test questions, and Chinese words and sentences actually occupy different areas, in order to improve the speed and accuracy of subsequent searches, it is necessary to cut the corresponding information around the cursor point in front of the captured camera, for example, assuming that the captured If the corresponding information around the cursor point in front of the camera is the test question, then the single test question near the cursor point is directly captured through the automatic frame question technology, and the automatic cutting of a single test question is completed; assuming that the capture includes the cursor point in front of the camera. If the corresponding information is a word, the word near the cursor point is directly captured through the automatic frame question technology.

Optionally, since starting the cursor consumes a certain amount of power, in order to save power of the mobile terminal, after the camera of the mobile terminal captures information around the cursor point in front of the camera, the following steps are included: closing the cursor.

Optionally, in order to capture clear information, before starting the camera of the mobile terminal to capture the information in front of the camera, it includes:

Detecting whether the distance between the information in front of the camera of the mobile terminal and the mobile terminal is less than a preset distance threshold, so that when the distance between the information in front of the camera of the mobile terminal and the mobile terminal is less than the preset distance threshold, the mobile terminal is activated The camera captures the information in front of the camera.

Specifically, a distance sensor is set on the mobile terminal (such as near the cursor) to detect the distance between the information in front of the camera of the mobile terminal and the mobile terminal. When the distance between the information in front of the camera of the mobile terminal and the mobile terminal is less than the preset When the distance threshold is set, it indicates that the camera can capture clear information. At this time, the camera of the mobile terminal is started to capture the information in front of the camera, thereby effectively saving resources.

Step S12, identifying the captured picture including the information in front of the camera as keyword text.

Specifically, through optical character recognition (Optical Character Recognition, OCR), such as through local OCR, or cloud OCR, the picture including the captured information in front of the camera is recognized as the keyword text. Among them, OCR refers to the process in which an electronic device (such as a scanner or a digital camera) checks characters printed on paper, determines its shape by detecting dark and light patterns, and then uses character recognition methods to translate the shape into computer text. When the captured information is recognized through local OCR, the recognition speed of information can be improved; when the captured information is recognized through cloud OCR, since the configuration of cloud OCR is usually high, the recognition accuracy of information can be improved.

Step S13, searching the vocabulary and sentence database for content corresponding to the keyword text.

Preferably, in order to improve the search speed, the word library is a local word library; in order to improve the search accuracy, the word library is a local word library.

Optionally, the step S13 includes:

B1. Compare the shape of the cursor point that is acquired with the shape of the cursor point stored in the pre-stored shape vocabulary database relationship table to determine the corresponding vocabulary database. The pre-stored shape vocabulary database relationship table stores different cursor points. Correspondence between shapes and different word libraries. For example, when the shape of the cursor point is in the shape of a cross, the corresponding word library is the test question word library; when the shape of the cursor point is circular, the corresponding word library is the Chinese word library; when the shape of the cursor point is square, the corresponding The phrase library is a word phrase library. In this way, when it is judged that the acquired shape of the emitted cursor point is a cross shape, the determined word library is the test question word library.

B2. Searching for content corresponding to the keyword text in the determined corresponding word library.

In the above-mentioned B1 and B2, since different phrase bases are subdivided, more accurate matching content can be searched faster in the subdivided phrase bases.

Step S14, outputting the searched content corresponding to the keyword text.

When the content corresponding to the keyword text is searched, the searched content is output in time.

Optionally, the outputting the searched content corresponding to the keyword text specifically includes:

C1. Display the searched content corresponding to the keyword text. For example, assuming that there are words and sentences in the English vocabulary database, as well as corresponding pronunciations, definitions, example sentences, etc., when the information matching the keyword text is searched, all the searched content will be displayed in time.

and / or,

C2. Broadcast the searched content corresponding to the keyword text.

By broadcasting the searched content, the form for the user to obtain the searched content is increased, so that the user can know the pronunciation of the information, and can also know the searched content through the broadcast without looking at the screen of the mobile terminal. As shown in FIG. 3 , when the searched content corresponding to the keyword text is Tiger and related definitions, "Tiger" and related definitions are broadcast. When local OCR recognition and local vocabulary search are used, the search speed can be greatly improved, and the effect of real-time instant reading can be achieved.

Optionally, the C1 specifically includes:

C11. Detect whether the mobile terminal is in a screen-off state.

C12. When the mobile terminal is in a screen-off state, display the searched content corresponding to the keyword text in a non-black font on the black screen of the mobile terminal.

When the mobile terminal is in a screen-off state, its screen has a black background. Therefore, in order to enable the user to clearly view the displayed content, the searched content is displayed in a non-black font. Preferably, the font color of the displayed content is different from black, for example, white, red, yellow, etc. Since the searched content can still be displayed when the mobile terminal is in a screen-off state, resource consumption caused by starting the mobile terminal is reduced. Of course, if the mobile terminal is in a non-off screen state, the searched content corresponding to the keyword text can be displayed in any color font on the black screen of the mobile terminal.

Optionally, in order to facilitate the user to quickly start the search operation, after the step S14, include:

D1. Display cursor graphics. After the user activates the cursor once by pressing the cursor key and outputs the searched content corresponding to the keyword text, a cursor graphic is displayed on the screen of the mobile terminal. Specifically, the cursor graphic can be displayed in the off-screen state, and the color of the cursor graphic is not black. For example, the color of the cursor graphic can be white as shown in FIG. 4 , of course, it can also be red or yellow, etc., which is not limited here . It should be pointed out that, if the mobile terminal is not currently in the screen-off state, the mobile terminal is in the screen-off state and then the cursor graphic is displayed.

D2. Receive a click instruction on the cursor graphic, and start the camera of the mobile terminal to capture information in front of the camera according to the click instruction.
