When adopt the QT/Embedded as the basic graphic library in a DTV platform,a framebuffer device is necessary to process the interrelated command of bottom.
在DTV平台中,如果采用QT/Embedded作为底层图形库,则需要帧缓冲(FrameBuffer)设备处理相关的底层命令。
This paper described how to design and complete an Embedded Video Living Monitoring System, which depended on embedded software developing, Linux graph collection, MPEG-4 compression, RTP translation, Linux framebuffer and use embedded CPU and Linux as developing platform.
本文以嵌入式处理器和Linux为开发平台,利用嵌入式软件开发技术,Linux下图像采集技术,MPEG-4压缩技术,RTP传输技术,Linux帧缓冲机制等设计并实现了嵌入式视频直播监控系统。
Facing with the problem of power consumption caused by large data stream and high frequency,an architecture-level low power technology based on dual-page frame buffer for LCD controller is presented in this paper.
针对LCD控制器数据处理量大和工作频率高的特点,提出了一种新型分页式帧缓冲结构。
If GUIs(graphic user interface) such as MiniGUI,MicroWindows of Qt-Embedded in the embedded Linux are used,LCD device drivers must be implemented as Linux frame buffer device drivers in addition to those low level operations which only deal with commands provided by LCD controllers.
嵌入式系统通常使用LCD作为显示设备,嵌入式Linux下,如果图形界面接口采用的是MicroWindows,MiniGUI或Qt-Embedded,则LCD设备的驱动程序必须采用Linux的帧缓冲设备来处理与LCD控制器有关的底层命令。
In this paper,the high resolution output technique is discussed and a new effective output method is obtained to be a solution to defects of traditional methods which are limited by the size of frame buffer.
论文围绕三维景观系统中的高分辨率输出技术进行了分析与探讨,针对传统输出方法因受帧缓冲大小的限制所存在的不足之处,提出了一种新的行之有效的高分辨率输出方法。
Nonlinear coding of tristimulus(RGB) is given as well as Gamma Correction based on the framebuffer color look-up table.
对图像处理中的GAMMA校正进行了详细分析,从CRT(阴极射线管)显示器和人类视觉特性两方面分析了GAMMA校正的必要性,给出了RGB三原色的非线性编码,并对GAMMA校正给出了基于帧缓存颜色查找表的实现方法。
