About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to two graphic preferred embodiments, can clearly present.
Consult shown in Figure 1, it is first preferred embodiment of electronic installation of the present invention, the electronic installation of present embodiment is to be example with notebook computer 100, it has the wide ratio of long x is 1600 * 800 wide screen LCD 10 (hereinafter to be referred as display 10), and Figure 1 shows that this notebook computer 100 is in order to the local main interlock circuit square that amplifies of the display frame of controlling this display 10, comprising video data temporary storage location 11, CPU (central processing unit) 12, video memory 13 and video processing unit 14.
Video data temporary storage location 11 is places of CPU (central processing unit) 12 access datas, and it may be primary memory or hard disk, wherein temporary original video (image) data that will be shown.
Video memory 13 (video RAM generally is called for short VRAM) stores finally will be sent to video (image) data that display 10 shows.
Be loaded with the local instruction of amplifying driver and requiring this part to amplify the driver execution in the CPU (central processing unit) 13 and import application program.Instruction input application program can provide " the local amplification " option to choose for the user on display picture, as shown in Figure 2, when this " local amplify " when option is selected, instruction input application program can be sent and locally amplify instruction and give CPU (central processing unit) 12, makes to carry out this part and amplify driver.Therefore, amplifying driver when the part is performed, as Figure 22, at first, the part zone of CPU (central processing unit) 12 definition display pictures is the amplification region, all the other zones are non-amplification region, and the amplification region can be located at the position that the user directly sees on the picture usually, that is the position of close middle (central authorities), and the amplification region is to present in the mode that occupies multiple row, that is to say if under copy editor's environment, in order to amplify literal wherein, the amplification region can occupy at least 2 row spaces of picture, so that literal wherein amplifies about 2 times at least than the literal of other non-amplification region.
Then, as step 23, CPU (central processing unit) 12 captures the video data in the non-amplification region that will be presented at display 10 and deposits the non-amplification data memory block of the corresponding non-amplification region of video memory 13 in from video data temporary storage location 11, carry out step 24 again, after acquisition will be presented at the video data and suitable amplification of amplification region from video data temporary storage location 11, deposit the amplification data memory block of the corresponding amplification region of video memory 13 in.
By this, as step 25, when video processing unit 14 reads the non-amplification data memory block and the video data in the amplification data memory block of video memory 13 and deliver to the display demonstration, just can see the video data that is exaggerated in the amplification region in the display frame of display, other then keeps existing size at the video data that non-amplification region shows.Below will further specify for example.
As shown in Figure 3, suppose that the picture 30 of the editor that copy editor's software produces can only hold 5 style of writing word contents on display, this 5 style of writing word content correspondence is stored in the memory block of video memory 13 as shown in Figure 4.
Yet because the general LCD of the spacing between the pixel of this kind wide screen displays is more dwindled, may cause in the editor picture 30 literal that shows too tiny and when having influence on the user and reading or edit, the user can select local the amplification via " the local amplification " option that instruction input application program provides, make CPU (central processing unit) 12 carry out the local driver that amplifies, and as shown in Figure 5, the 3rd of definition picture 30,4 behavior amplification regions 31, all the other zones are non-amplification region, and because amplification region 51 is provided in a side of about centre position of picture 30, so non-amplification region is divided into non-amplification region 32 the (promptly the 1st, 2 row) reach non-amplification region 33 (i.e. the 5th row) down.And the usefulness of amplification region 31 be intended to make the literal that is positioned at wherein for example " CCCC " can be exaggerated.And in order to allow the amplification region 31 unlikely literal that covered in last non-amplification region 32 and the following non-amplification region 33, the literal " DDDD " that originally was presented at the 4th, 5 row in the picture 30 reaches " EEEE " and just must past move down delegation, therefore, " EEEE " will be extruded in the picture 30.In order to reach this effect, CPU (central processing unit) 12 can read from video data temporary storage location 11 again and will be presented at non-amplification region 32 the (promptly the 1st, 2 row) video data, i.e. " AAAA " and " BBBB ", and deposit first memory block 131 of video memory 13 as shown in Figure 6 in, from video data temporary storage location 11, read the video data that will be presented at amplification region 31 again, i.e. " CCCC ", and after carrying out processing and amplifying, deposit second memory block 132 of video memory shown in Figure 6 13 in, and from video data temporary storage location 11, read the video data that will be presented at down non-amplification region 53, i.e. " DDDD ", and deposit the 3rd memory block 133 of video memory shown in Figure 6 13 in, and first～the 3rd memory block 133 is the continuous positions that are positioned at video memory 13 in regular turn.That is first memory block 131 and the 3rd memory block 132 are the non-amplification data memory block that store non-amplified video data.
By this, when video processing unit 14 read in regular turn video memory 13 first, second and third memory block 131～133 video content and when delivering to display and showing, as shown in Figure 7, just can see the video data " CCCC " that is exaggerated in the amplification region 71 in the picture 70 of the editor of display, and other is in non-amplification region, and the video data " AAAA ", " BBBB " and " DDDD " that promptly go up non-amplification region 72 and 73 demonstrations of down non-amplification region then keep existing size.
In addition, when 80 last columns of cursor at picture 70, the 5th when row just, if the user controls when cursor is past to move down delegation, CPU (central processing unit) 12 just needs the video data in the real-time update video memory 13, again the corresponding video data of acquisition is deposited in first～the 3rd memory block 131～133 of video memory 13 as shown in Figure 8 from video data temporary storage location 11, and as shown in Figure 9, that delegation's literal " EEEE " at cursor 80 places is entered in the picture 70, and " AAAA " of first row will be extruded picture 70, and the lastrow literal " DDDD " that takes turns to cursor 80 positions enters amplification region 71 and is exaggerated.
Therefore,, just can in time amplify the word content that the user is watching or editing, and help the user to carry out the editor or the operation of literal, particularly when using the higher LCD of resolution by display frame by above-mentioned mechanism.
Again referring to shown in Figure 10, it is second preferred embodiment of electronic installation of the present invention, its circuit box and first embodiment are identical, it is not to reach the local function of amplifying of displaying contents by carrying out (the local amplification) driver that unique difference is in CPU (central processing unit) 12, reaches above-mentioned local amplification effect but change by carrying out the local application program of amplifying.Below the flow process that will amplify the local content of picture to this part amplification application program for example is elaborated.
Suppose that present embodiment also is " CCCC " this delegation's word that will amplify in the picture shown in Figure 3 30, then referring to the step 101 of Figure 10, after this part amplification application program receives " the local amplification instructed ", it carry out step 102, as shown in Figure 5, the 3rd, 4 behavior amplification regions 31 of definition picture 30, all the other zones are non-amplification region (comprise non-amplification region 32 and reach non-amplification region 33 down).
Then, as step 103, CPU (central processing unit) 12 can read from video data temporary storage location 11 again and will be presented at non-amplification region 32 the (promptly the 1st, 2 row) video data, i.e. " AAAA " and " BBBB ", and deposit first memory block 111 of video memory 13 as shown in figure 11 in, and from video data temporary storage location 11, read the video data that will be presented at down non-amplification region 53, i.e. " DDDD ", and deposit second memory block 112 of video memory shown in Figure 11 13 in, step 104 for another example, from video data temporary storage location 11, read the video data that will be presented at amplification region 51, i.e. " CCCC ", and after carrying out processing and amplifying, deposit the amplification data memory block 113 of video memory shown in Figure 11 13 in, and, in the 3rd memory block 114 of video memory 13, store the window data that will be presented on the amplification region 51 as step 105; Wherein first memory block 111 and second memory block 112 are discontinuous but be arranged in the zones of different of this video memory 13 in regular turn, and the blank storage space 115 that is equivalent to these amplification data memory block 113 sizes between the two at interval, and the 3rd memory block 114 and amplification data memory block 113 are positioned at after second memory block 112 in regular turn.
By this, when video processing unit 14 is subjected to CPU (central processing unit) 12 controls, read in regular turn video memory 13 first memory block 111, blank storage space 115 and second memory block 112 video data and when delivering to display 10, as shown in figure 12, can be on picture 120 non-amplification region 121 (i.e. first row and second row) and following non-amplification region 122 (being fifth line) show that respectively video data " AAAA ", " BBBB " of existing size reach " DDDD ", and second go and fifth line between formation clear area 123.And when video processing unit 14 then reads the window data in the 3rd memory block 114 of video memory 13 and delivers to display 10, as shown in figure 13, can produce and amplify window 124 overlappings on clear area 123, and when video processing unit 14 continues to read the amplified video data " CCCC " in the amplification data memory block 113 of video memory 13 and delivers to display 10, then amplified video data " CCCC " can be presented at and amplify in the window 124.
And similarly, as Fig. 7 and shown in Figure 8, be positioned at last column of picture when cursor, the 5th when row just, if the user controls cursor 80 when moving down delegation, CPU (central processing unit) 12 just needs the video data in the real-time update video memory 13, again the corresponding video data of acquisition is deposited first of as shown in figure 12 video memory 13 from video data temporary storage location 11, in second memory block 111～112 and the amplification data memory block 113, and as shown in Figure 8, that delegation's literal " EEEE " at cursor 80 places is entered in the picture, and " AAAA " of first row will be extruded picture 120, and the lastrow literal " DDDD " that takes turns to cursor 80 positions enters to amplify in the window 124 and is exaggerated.
In like manner, when the user is amplifying in the window 124 that input characters reaches delegation and when needing line feed, originally the magnifying text in amplifying window 124 promptly can be squeezed toward lastrow and returned to existing font size before amplifying, amplifying window 124 then amplifies delegation's literal of new input, that is amplify third and fourth line position that window 124 can be fixed on picture, and amplify the literal that enters in the amplification window 124.
In addition, what deserves to be mentioned is, the tram that the amplification window 124 of present embodiment can auxiliary video processing unit 14 be delivered to display with amplification data shows, but amplify window 124 and inessential, do not amplify window 124, still the video data after amplifying directly can be overlapped is presented on the amplification region (clear area) of picture.
Therefore, application program is amplified in part by second embodiment, electronic installation can amplify in time also that the user is watching or the display picture edited in word content, and help the user to carry out the editor or the operation of literal by display frame, particularly when using the higher LCD of resolution.
The above person of thought, it only is preferred embodiment of the present invention, when not limiting scope of the invention process with this, promptly the simple equivalent of being done according to claim scope of the present invention and invention description content generally changes and modifies, and all still belongs in the scope that claim of the present invention contains.
