It is described in detail below with a concrete application scene, please refers to Fig. 6 to Fig. 8, application examples includes:
Since 4K output is commonplace, but 3840 × 2160@15Hz when output, the output of 15 frames, picture compare Caton,
It is bad to echo effect.The echo of 1080P@60hz exports, 60 frames, and frame per second is high, but pixel is not high, if display terminal is very big
Area, then echo is fuzzy, effect same is bad.
It is whole wall echo display for 1920 × 1080,2 rows 4 column output wall with single screen output:
Row total resolution are as follows: 1920 × 4=7680
Column total resolution are as follows: 1080 × 2=2160
1): the common echo mode of 4K:
It is exported if it is 3840 × 2160@15Hz, normally echoes rule according to ranks, then zoom factor is 1/2.
The ranks total resolution of i.e. whole wall will be scaled original 1/2, i.e., echo effective resolution is 3840 × 1080@
15hz, i.e. half screen echo display.
2) the optimal echo mode of 4K
If 4k echoes display according to 30Hz, 4K resolution ratio both of which: 3840 × 1080 and 1920 × 2160.
A. it according to the first mode, exports as 3840 × 1080@30Hz
(if it is more than 2 points, just regard is at 3 to the first row zoom factor=row total resolution/3840=7680/3840=2
Reason)
(if it is more than 2 points, just regard is at 3 to first row zoom factor=column total resolution/1080=2160/1080=2
Reason)
According to the first maximum calculation of ranks zoom factor, because according to the smallest calculation, then screen is overflowed in other meeting.
So selecting row zoom factor is 2.
B. it according to second of mode, exports as 1920 × 2160@30Hz
(if it is more than 4 points, just regard is at 5 to second row zoom factor=row total resolution/1920=7680/3840=4
Reason)
(if it is more than 1 point, just regard is at 2 to secondary series zoom factor=column total resolution/2160=2160/2160=1
Reason)
According to the second maximum calculation of ranks zoom factor, because according to the smallest calculation, then screen is overflowed in other meeting.
So selecting row zoom factor is 4.
C. optimization model is selected
The first mode zoom factor is 2, and second of mode is scaled 4, minimum excellent according to image scaling, so selection
The first mode is the optimal output mode of 4K.
In conjunction with information above, according to 3840 × 1080@30Hz of the first mode, then echoing zoom factor or 2, still
Echo effective resolution is 3840 × 1080@30hz, and full frame echo is shown.
