4、logy, the refresh rate is the number of times that the image on the display is drawn each second. If your CRT monitor has a refresh rate of 72 Hertz (Hz), then it cycles through all the pixels from top to bottom 72 times a second. Refresh rates are very important because they control flicker, and yo

5、u want the refresh rate as high as possible. Too few cycles per second and you will notice a flickering, which can lead to headaches and eye strain. 在基于显像管技术的监视器的刷新率是上显示的图像绘制的每秒的次数。如果您的 CRT 显示器的 72 赫兹 (Hz) 刷新率,然后它循环通过的所有像素都从顶部到底部每秒 72 次。刷新率是非常重要的因为他们控制闪烁,并且您希望尽可能高的刷新率。每秒,你太少周期将通知闪烁,从而导致头痛和眼睛疲劳。Telev

6、isions have a lower refresh rate than most computer monitors. To help adjust for the lower rate, they use a method called interlacing. This means that the electron gun in the televisions CRT will scan through all the odd rows from top to bottom, then start again with the even rows. The phosphors hol

Cameras with high megapixel ratings take larger pictures with more detail. Those photos will also look better when printed, especially in bi

13、peed is 1/2000 of a second, while camera settings usually allow up to about one second, which is very slow. One-sixtieth of a second is about as slow a shutter speed as you can use when taking a hand-held shot, and not get any blur. Some photographers force their camera shutters to stay open for muc
