介紹一種偽彩色顯示的圖像采集系統(tǒng)。該系統(tǒng)具有分辨率可調(diào)，序列圖像攝取、顯示、存儲(chǔ)等功能。由于系統(tǒng)的工作同步于視頻場(chǎng)，使得該系統(tǒng)可以在40ms 內(nèi)完成一幅512×512×8bit 圖像的攝取和顯示。此外，偽彩色增強(qiáng)電路的實(shí)現(xiàn)，可大大提高人們對(duì)圖像的辨識(shí)能力。該系統(tǒng)具有速度快、實(shí)時(shí)性強(qiáng)、操作簡(jiǎn)單等特點(diǎn)。它可廣泛應(yīng)用于生物醫(yī)學(xué)工程，衛(wèi)星遙感圖像處理及工業(yè)檢測(cè)等領(lǐng)域。

Abstract: This paper describes a pseudo-color TV frame grabber in detail. The system has the function of resolution control, sequential image grabbing, display and store. Because the system is synchronized with TV field synchronization, It can finish the grabbing and display of 512×512×8 bit image within 40ms. The pseudo-color output of system can greatly enhance man’s understanding accuracy of the picture. The system has the features of high speed, real-time and simple operation. It can be used in biomedical engineering, remotely sensed image
processing and industrial inspection, etc.
