Fig. 3 is the placement location schematic diagram checking picture in buffer queue after next secondary picture.
Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
In the present embodiment, assuming that the numbering of this buffer queue memory location is from left to right followed successively by 0,1,2 ... N-1, the current picture just shown should be deposited in the position (being namely numbered the position of (N-1)/2) that then this buffer queue is middle, (N-the 1)/2 width picture before current display picture should be deposited in a memory location, (N-1)/2 on the buffer queue left side, and current display picture (N-1)/2 width picture below should be deposited in the memory location, (N-1)/2 on the right of buffer queue.
The invention discloses a kind of television local image display method, it comprises following steps:
After a width picture opened by television set, (N-1)/2 picture in current display picture and former and later two directions of current display picture is loaded in a buffer queue on backstage by television set, the picture number that described buffer queue can be deposited altogether is N, the numbering of described buffer queue memory location is from left to right followed successively by 0,1,2 ... N-1, described N be greater than 1 odd number.
When user checks a upper width picture of current display picture, delete the picture in buffer queue, rightmost memory location stored, then all move right all the other all pictures stored in buffer queue a position, finally shown (the upper width picture that this picture is exactly the current display picture that user wants to open) by the picture that most for buffer queue centre position stores.Like this, after the operation of user " checking a upper width picture ", the picture stored in buffer queue just reduces by a width.
In like manner, when user checks next width picture of current display picture, delete the picture in buffer queue, Far Left memory location stored, then all the other all pictures stored in buffer queue are all moved to the left a position, finally the picture that most for buffer queue centre position stores are shown (next width picture that this picture is exactly the current display picture that user wants to open).Like this, after the operation of user " checking next width picture ", the picture stored in buffer queue just reduces by a width.
By front and back (N-1)/2 picture of current display picture and photo current all pre-loaded in a buffer queue, directly read from buffer queue when Showing Picture, and need not reload, which greatly improves the speed of picture display, improve the efficiency browsing local picture on a television set, thus greatly improve the operating experience of user.
When the picture number stored in buffer queue reduce to equal certain threshold values (assuming that this threshold values is M, preferably M equals (N-1)/2) time, just start immediately to load N-M width picture on backstage, to fill up this buffer queue.
This N-M width picture that will load is that those have not had the memory location of picture to determine by buffer queue.Such as, assuming that the memory location being numbered R does not have picture, when R < (N-1)/2(i.e. this memory location is positioned at the left side in the most centre position of buffer queue) time, should load with current display picture distance is (N-1)/2-R, and that width picture be positioned at before current display picture, and be stored in buffer queue and be numbered on the memory location of R.
When R > (N-1)/2(i.e. this memory location is positioned at the right in the most centre position of buffer queue) time, should load with current display picture distance is R-(N-1)/2, and be positioned at current display picture that width picture below, and be stored in buffer queue and be numbered on the memory location of R.
N needs comprehensively determine according to the internal memory of television set and processor performance, and preferably, N is 7.When N is 7, from left to right, in buffer queue, the numbering of each memory cell is followed successively by 0, and 1,2,3,4,5,6.The memory cell being numbered 3 in buffer queue is the middle memory cell of buffer queue, for depositing the picture of current display; Be positioned at memory cell 0,1,2 on the left of the most centre position of buffer queue for storing three width pictures before current display picture; Be positioned at memory cell 4,5,6 on the right side of the most centre position of buffer queue for storing three width pictures after current display picture.After user opens a width picture, this width picture (being referred to as current display picture) that active user just opens by we is stored into the middle memory location of buffer queue, is namely numbered the memory location of 3.After user opens a width picture, each for the front and back of current display picture three width pictures are loaded in the respective memory locations of buffer queue on backstage by we, as shown in Figure 1.In buffer queue, the picture that the memory location being numbered 2 stores is exactly a upper width picture of current display picture; The picture that the memory location being numbered 1 stores is exactly a upper width picture of the memory location institute picture being numbered 2, the like.When user operation " checks a upper width picture ", we just first delete the upper picture stored in rightmost memory location (being namely numbered the memory location of 6) in buffer queue, then all move right all the other all pictures stored in buffer queue a position, finally upper for most for buffer queue centre position (being namely numbered the memory location of the 3) picture stored is shown to user, as shown in Figure 2.When user operation " checks next width picture ", we just first delete the upper picture stored in Far Left memory location (being namely numbered the memory location of 0) in buffer queue, then all the other all pictures stored in buffer queue are all moved to the left a position, finally upper for most for buffer queue centre position (being namely numbered the memory location of the 3) picture stored is shown to user, as shown in Figure 3.Often through once " checking a upper width picture " or after the operation of " checking next width picture ", buffer queue will reduce by a width picture, the picture number stored in buffer queue is caused to be less than threshold values R(R=N-1 when repeatedly performing these two kinds of operations)/2) time, we just load N-R width picture immediately in buffer queue on backstage.
More than above are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
