Embodiment 1

[0059] See figure 1 , which shows a flowchart of a character output control method provided by the present invention, including:

[0060] Step 101, the smart TV acquires the image scanned by the camera.

[0061] In this embodiment, the smart TV can control the rotating camera to scan with a large viewing angle. Preferably, the smart TV acquires the current user area of ​​the smart TV through rotating and scanning the camera. In practical application scenarios, users generally sit at the front of the smart TV, and the area where the user can normally watch the smart TV is called the user area. In the present invention, the camera can completely scan and take pictures of the user area to obtain images of the current user area.

[0062] In step 102, the smart TV detects whether there is a face area in the image. If it exists, execute step 103; if not, execute step 104.

[0063] In this embodiment, after the smart TV acquires the image scanned by the camera, it uses a face re...

Embodiment 2

[0071] Based on the above examples, please refer to figure 2 , which shows another flowchart of a character output control method provided by the present invention, including:

[0072] In step 201, the smart TV acquires an image scanned by a camera.

[0073] In step 202, the smart TV detects whether there is a face area in the image. If it exists, execute step 203; if not, execute step 205.

[0074] The description of the above steps is the same as that of the foregoing embodiments, and the inventors will not repeat them here.

[0075] In step 203, the smart TV judges whether the number of face regions in the image meets the preset requirements. If it is satisfied, go to step 204; if not, go to step 205.

[0076] In this embodiment, the preset requirement may be that the number of face regions is greater than 0 and less than or equal to a certain threshold. For example, if the threshold is set to 2, the smart TV judges whether the number of face regions in the image is 1...

Embodiment 3

[0081] Based on the above examples, please refer to image 3 , which shows another flow chart of a character output control method provided by the present invention, including:

[0082] In step 301, the smart TV acquires an image scanned by a camera.

[0083] In step 302, the smart TV detects whether there is a face area in the image. If it exists, execute step 303; if not, execute step 305.

[0084] In step 303, the smart TV judges whether there is a feature of glasses in the face area. If it does not exist, perform step 304, and if it exists, perform step 305.

[0085] Wherein, the glasses features refer to features that can represent glasses. Such as glasses frames, glasses lenses, nose pads, etc. In this embodiment, judging whether there are glasses features in the face area may specifically include, for example Figure 3a Shown:

[0086] Step 3031, use the face recognition algorithm to calculate the image part of the eyes in the face area. Preferably, the face rec...

Abstract

The invention discloses a control method and device for outputting characters. The control method and device are applied to an intelligent television. The control method comprises the following steps that an image is obtained through scanning of a camera; whether a face area exists in the image is detected; if the face area exists in the detected image, the intelligent television is controlled to amplify the format of the characters, and the characters are output. In the control method and device for outputting characters, when a short-sighted user watches the intelligent television, the intelligent television detects that the short-sighted user exists and controls the format of the characters to be amplified, and the characters are output. At the moment, short-sighted people can take off glasses to watch the intelligent television and do not depend on the glasses, so that the control method and device for outputting characters meet the visual requirements of the short-sighted people.

Description

technical field [0001] The present invention relates to the technical field of smart TV control, and more specifically, to a character output control method and device. Background technique [0002] With the continuous development of science and technology, the implementation functions of smart TVs have also been rapidly expanded. [0003] In the prior art, whether it is an ordinary TV or a smart TV, when outputting data information, it will be accompanied by the output of subtitles. As we all know, the setting of the character size in the subtitle is set by the system designer himself according to the design experience. The starting point is to ensure that the output characters are not too large and occupy too many display positions on the display screen, which will affect the user's viewing of other audio and video effects, and ensure that the user can see the characters clearly. [0004] However, it is not difficult to find that the setting of the size of the output cha...
