Abstract
The present invention relates to a sub-picture video decoding device. In the device, at least one kind of sub-picture data is temporarily stored in a sub-picture buffer unit, a plurality of adjustment parameters are stored in an adjusting unit, and at least one kind of sub-picture data is in contrast with a sub-picture display format in a contrast table by a control unit; the control unit receives adjusting signals generated by an input unit so as to take out the values of the corresponding adjustment parameters on the basis of the adjusting signals, adjust at least one sub-picture video through the values of the adjustment parameters and display the sub-picture video.
Description
Technical field
The invention relates to a kind of image-decoding device, refer to a kind of subframe image-decoding device especially.
Background technology
Present audio and video player can show the function of two kinds of different language captions at the most simultaneously, as shown in Figure 1.Yet its captions displaying location of playing is fixed, and covers important background frame easily, and stops the absorption of human eye for the picture message.Again, the font size of the captions that audio and video player is shown is for fixing, can't adjust the size of font, and causes remote audience's the dimness of vision with tired easily.At last, the shown captions brightness of audio and video player often can't be adjusted separately, for example: when background video changes, if background luminance is similar to captions brightness, because of captions brightness can't be adjusted, and make the audience that subtitle image and background video are obscured together easily.Therefore, how to separate the subframe image-decoding device of time above-mentioned disappearance, become a utmost point and need separate inferior problem.
Summary of the invention
Main purpose of the present invention is that a kind of subframe image-decoding device is being provided, can amplify or dwindle arbitrary demonstration caption area.
Another object of the present invention is in that a kind of subframe image-decoding device is provided, can adjust the position of arbitrary demonstration caption area.
Another purpose of the present invention is in that a kind of subframe image-decoding device is provided, the brightness of arbitrary demonstration caption area being adjusted.
For reaching above-mentioned purpose, a kind of subframe image-decoding of the present invention device, it comprises: a picture buffering unit is in order to receiving the subframe data, and temporary this subframe data; One adjustment unit is to prestore plural kind to adjust parameter, and each kind is adjusted parameter and had at least one corresponding parameter value of adjusting; Comparison list has provided plural subframe display format, contrasts in these subframe display formats for this subframe data, to obtain picture image one time; One input unit is to adjust signal in order to produce one; And a control unit, be to take out corresponding adjustment parameter value according to this adjustment signal, adjusting this subframe image according to this adjustment parameter value, and show it.
Described subframe image-decoding device, wherein, this adjustment unit is to comprise multiple transient memory, each buffer stores a kind of adjustment parameter respectively.
Described subframe image-decoding device wherein, stores the adjustment parameter value of plural identical type in each buffer.
Described subframe image-decoding device, wherein, these adjust parameter is to comprise a picture position to adjust parameter, subframe convergent-divergent adjustment parameter and a picture brightness adjustment parameter.
Described subframe image-decoding device, wherein, this table of comparisons is to be stored in the memory storage unit.
Described name face is as decoding device, and wherein, this at least one subframe image is to see through diffusing point (Scaller) unit and key frame image coupling, exports a display unit then to.
Described subframe image-decoding device, wherein, these subframe display formats are to be text formatting.
Description of drawings
Fig. 1 is the broadcast schematic diagram of existing audio and video player;
Fig. 2 is the functional block diagram of a preferred embodiment of the present invention;
Fig. 3 (A), 3 (B) are the operation charts of a preferred embodiment of the present invention.
Embodiment
Relevant preferred embodiment of the present invention, be to be example with a language learner, please be with reference to the functional block diagram of Fig. 2 demonstration, it mainly is made up of input unit 1, control unit 2, subframe buffer cell 3, adjustment unit 4, the table of comparisons (Look-Up Table) 5, the main members such as dot element (Scaller) 6 and display unit 7 that loose, wherein, the table of comparisons 5 is to be stored in (figure does not show) in the memory storage unit.In present embodiment, input unit 1 is preferably the keyboard group on the display floater, and it is to adjust signal in order to produce key frame or subframe, in the present embodiment, will adjust signal at subframe and be illustrated.
Above-mentioned subframe buffer cell 3 has first buffer 31 and second buffer 32, (it can be first kind of language subtitle to be used for storing first kind of subframe data respectively, for example: English) (it can be second kind of language subtitle, for example: Chinese) with second kind of subframe data.Adjustment unit 4 has three buffers 41,42,43, adjust the adjustment parameter of three kinds such as parameter, subframe convergent-divergent adjustment parameter and subframe brightness adjustment parameter to store the subframe position respectively, and each is adjusted parameter and has multiple parameter values, to represent diverse location, different size and different brightness etc.Then have plural subframe display format in the table of comparisons 5, in present embodiment, these subframe display formats are to be text formatting.
When input unit 1 is not sent subframe adjustment signal to control unit 2, control unit 2 is with the subframe display format in stored first kind of subframe data in the subframe buffer cell 3 and the second kind of subframe data comparison table of comparisons 5, to obtain first kind of subframe image and second kind of subframe image, and export the dot element 6 that looses to, for diffusing dot element 6 key frame image and the subframe image that is received is coupled, exports display unit 7 demonstrations then to.
When input unit 1 is sent subframe adjustment signal to control unit 2,2 of control units are adjusted signal according to subframe and are chosen adjustment parameter (parameter is adjusted in the subframe position, the subframe convergent-divergent adjusts parameter or parameter is adjusted in subframe brightness) in the adjustment unit 4, adjust these subframe images (being in advance to compare subframe display format in the table of comparisons 5 for these subframe data) to adjust parameter by this.For example: adjust parameter if choose the subframe position, then control unit 2 is adjusted the position offset of parameter representative or is offset address according to selected subframe position and adjusts first kind or second kind of subframe image, covers the key frame image to avoid these subframe images.
Adjust parameter if choose the subframe convergent-divergent, then control unit 2 is adjusted the amplification of parameter representative or minification according to selected subframe convergent-divergent and is adjusted first kind or second kind time and draw and image.And adjust parameter if choose subframe brightness, then control unit 2 is adjusted the brightness of first kind or second kind subframe image according to the luminance parameter of selected subframe brightness adjustment parameter representative.
By above explanation as can be known, the present invention utilizes adjustment unit to store plural number to adjust parameter, control unit is then adjusted signal according to the subframe that input unit produced and is chosen an adjustment parameter, and see through to adjust parameter and adjust the subframe image, adjust with the position that can amplify or dwindle arbitrary demonstration caption area (subframe), the arbitrary demonstration caption area of adjustment and to the brightness of arbitrary demonstration caption area.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
