Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] In the embodiment of the present invention, it is necessary to establish a mapping table of station logo information: the mapping table of station logo information can be stored in the terminal, or stored on the network side by the TV program operator. sent to the terminal. Considering that TV stations generally do not easily change the station logo, and TV program operators do not easily change the frequency and channel of program broadcasting, it can ...

Abstract

The present invention provides an information identification method, device, and mobile terminal. The information identification method includes: obtaining a mapping table of the station logo information of the currently playing TV station; The station logo picture of the TV station carries out text recognition training, compares the information in the station logo in the station logo information in the training result and the station logo information mapping table, obtains the filter parameter after the correction; Utilizes the filter parameter after the correction , to identify the text information appearing in the program of the currently played TV station. The information recognition device includes: a mapping table acquisition unit, a recognition training unit, and a character recognition unit. The mobile terminal includes the above information identification device. The invention overcomes the influence of different settings of display screens (for example: brightness, contrast, saturation, etc.), and improves the success rate of character recognition.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an information identification method, device and mobile terminal. Background technique [0002] When playing a video on the terminal, the user sometimes hopes that the terminal can recognize the text information in the video stream. In particular, some video programs are time-sensitive, fleeting, and cannot be played again, and the terminal is limited by the screen size, so text information recognition is very important. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: when the user watches programs of different TV stations or the same terminal is in different environments, the settings of the display screen (for example: brightness, contrast, saturation, etc.) degree, etc.) will be different, which will affect the success rate of text information recognition.
