luminance brightness
1.L(b)=240,220,200,180,86%-100% subjects reported a+b>b+a. And as the difference between a luminance and b luminance decreased,the brightness of two sides was more similar.
2.In this thesis, the image enhancement was also studied, such as DLTI、DCTI(digital luminance、color transient improvement), PEAKING(luminance peaking), BLE(black-level enhancement), brightness、hue、contrast and saturation adjustment, and then the hardware circuit was designed.
3.The ZnS:Zn,Pb phosphor with chromaticity of X=0. 145, Y=0. 166 for Low-voltage blue emission is being developed. This luminance phosphor is almost the same brightness with ZnO:Zn and higher than ZnS:Zn. When it was mixed with In2O3 whose particle size is half of the phosphor, the threshold voltage will decrease from 80 V to 8 V. It is suitable for FED and VFD application.
4.In the video process chapter, some researches on DCTI(digital color transient improvement),DLTI(digital luminance transient improvement), PEAKING(luminance peaking), BLE(black-level enhancement), WLE(white-level enhancement), brightness, hue, contrast and saturation adjustment were done, and then the hardware circuit was designed.
