| 摘 要： | 介绍了一种字符叠加显示电路的设计方法。通常字符叠加的方法是直接在图像上进行模拟或数字信号叠加的,但当图像信号和字符信息的灰度级相当时,字符很难被分辨。通过对CPLD时序进行控制来增加字符区文字与图像对比度的方法可改善观察效果。 |
| 关 键 词： | 图像监测系统 字符叠加 图像信号 字符信息 |

| Abstract: | Design of a display circuit for characters adder is introduced.Characters are conventionally directly added on image.This method causes low contrast when the gray level of image and that of characters is near to each other.A method that increases the contrast between characters and image through CPLD time sequence control is introduced.The method has been applied in real system. |
| Keywords: | image monitoring system characters adding image signal information in characters |
