The dvd recent three stars face toes the chinese consumer, releases the world the section 1 to make to order for high and clear degree television to broadcast the, namely three stars the dvd - hd938, it can pass the general port to realize the pal system the type bottom to is every other line with the line painting quality for scanning outputting 576 is 576 p, can emerging the export surplus commonly even pal system type line scanning ; but the adoption image strengthen the technique to ask for help the dvi port to can more realizes 1080 is 720s p exportation result. more important, pass to see the format conversion of the, and the can of high and clear degree television is produceding can attain of distinguish the rate. 1080 is 720 p
慧聰影音商務網最近三星面向中國消費者，推出了世界第一款為高清晰度電視定製的dvd播放器，即三星dvd - hd938 ，它可以通過一般埠實現pal制式下隔行和逐行掃描輸出576i 576p ，能夠展現出超過普通甚至pal制式逐行掃描的畫質而採用影像增強技術藉助dvi埠更可以實現1080i 720p輸出效果。更重要的是，通過視頻的格式轉換，可以產生高清晰度電視所能達到的解析度1080i 720p 。 -
Employing the interlaced scanning, current tv system can compress the frequency band of tv signal effectively and facilitate transmission. but this method reduces the scanning lines of pictures and the frequency of the field. it leads the pictures displayed on tv to have such disadvantages as large area flicker, edge flicker, interlace flicker, raster visibility and creeping line etc. to satisfy people " s vision feeling better, the big - screen, multi - function and high quality tv - set have been made great progress
現行的廣播電視系統由於採用隔行掃描方式，從而有效地壓縮了電視信號的頻帶，有利於傳輸；但由於這種方式使得圖像的掃描行數少，場頻低，導致了重顯的電視圖像有大面積閃爍、邊緣閃爍、行間閃爍、行結構可見及行爬行等。 -
So the plate - like drawing correcting process can be divided into two stages : absolute errors checking and comparative errors checking absolute errors checking include four modules which were line - weight checking, hatch checking. dimension checking and overlapped line checking comparative errors checking module include drawing compartmentalization, view recognizing, data getting and data compare in this correction system, line - scanning and circle - scanning algorithm, direct graphics element compare algorithm and character compare are used, which simplify the process and reduce difficulties
相對錯誤檢查包括區域劃分、視圖識別、數據提取、數據提取等過程。相對錯誤的判斷依據是答案圖。本批改系統採用直線和圓弧掃描演算法，並且結合圖形元素直接比較法和特徵比較法，既簡化了處理過程，又降低了處理難度，比較圓滿地完成了開題報告確立的任務。 -
