Problems solved by technology

However, the display position of the subtitles it plays is fixed, and it is easy to cover important background images, which prevents the human eye from absorbing the information of the images.
In addition, the font size of the subtitles displayed on the audio-visual player is fixed, and the font size cannot be adjusted, resulting in blurred vision and fatigue for long-distance viewers.
Finally, the brightness of the subtitles displayed on the video player cannot be adjusted independently. For example, if the brightness of the background is similar to the brightness of the subtitles while the background image is changing, the brightness of the subtitles cannot be adjusted, which may easily confuse the viewer with the subtitle image and the background image. together

Embodiment Construction

[0016] The preferred embodiment of the present invention is an example with a language learning machine, please refer to the functional block diagram shown in Fig. The look-up table (Look-Up Table) 5, the scatter unit (Scaller) 6 and the display unit 7 are composed of main components, wherein the look-up table 5 is stored in a memory storage unit (not shown). In this embodiment, the input unit 1 is preferably a keyboard set on the display panel, which is used to generate a main picture or a sub-picture adjustment signal. In this embodiment, the sub-picture adjustment signal will be described.

[0017] The input unit 1 is electrically connected with the control unit 2, and the control unit 2 is respectively electrically connected with the buffer unit 3, the adjustment unit 4, the memory storage unit storing the comparison table 5, and the scatter unit 6, and the scatter unit 6 Then it is electrically connected with the display unit 7 .

[0018] The above-mentioned sub-picture ...

Abstract

The present invention relates to a sub-picture image decoding device, which mainly uses a sub-picture buffer unit to temporarily store at least one kind of sub-picture data, an adjustment unit to store multiple types of adjustment parameters, and a control unit to compare the at least one sub-picture data with the comparison The sub-picture display format of the table, and the control unit receives the adjustment signal generated by the input unit, and is used to obtain the corresponding adjustment parameter value according to the adjustment signal, so as to adjust at least one sub-picture image through the adjustment parameter value and display it.

Description

technical field [0001] The present invention relates to an image decoding device, in particular to a sub-picture image decoding device. Background technique [0002] The current audio-visual player can display subtitles in two different languages ​​at most at the same time, as shown in FIG. 1 . However, the display position of the subtitles played by it is fixed, and it is easy to cover important background pictures, thereby blocking the absorption of picture information by human eyes. Also, the font size of the subtitles displayed by the audio-visual player is fixed, and the size of the font cannot be adjusted, resulting in blurred vision and easy fatigue for long-distance viewers. Finally, the brightness of the subtitles displayed on the video player cannot be adjusted independently. For example, if the brightness of the background is similar to the brightness of the subtitles while the background image is changing, the brightness of the subtitles cannot be adjusted, whic...
