Description

1220844 V. Description of the invention (1) [Technical field to which the invention belongs] Fang, this case is-a single frame data processing in the deinterlacing scanning process To perform de-interlacing. [The previous technique used a computer screen scan to divide the image into two frames, so the display system does not flash as the technique progresses. The TV signal moves to complete the image.] Two consecutive images of the TV ' The diurnal surface of the day is very clear that the digital plane must be used in the image of the 'plane'. The signal's diurnal surface is interlace rather than progressive. Interlace

Image frame, the singular scan line (Scan Une) forms a f = line frame when forming another image. Conventional TV system: The ancient 2 TV signal number is displayed on the TV screen, ^. Second micro flicker, but because of the persistence of the visual system and flat _; TV production: = panel (such as liquid crystal display, LCD) technology Flat display 2 continued to be launched. When interlaced scanning is developed, it must be more serious. Therefore, the singular scanning & de-interlacing operation is displayed on the LCD. When de-interlacing, the image of the even-scanned image is expanded into one, such as _he at 72 0x48 0

Each scan line has 720 points, and in the two panels, there are a total of 480 scan lines and 72 0x240 screens. Therefore, the electrical screen ^ video rotation screen is divided into two incoming screens. Press 'Right' to input directly to the display panel and replace it, so there will be a flicker phenomenon. The scanning line and the odd scanning line intersect each other. If you want to display on the display panel normally

1220844 V. Description of the invention (2) The daytime surface of each 72 Ox240 must be expanded to a picture of 72 0x480. The extension date must take into account the nature of the image, such as static or dynamic, and interpolate related data according to the time and quality of the image. At the same time, the quality of the image must be considered. Even scanning lines need to interpolate odd scanning lines. Similarly, odd scanning lines need inner scanning lines. Therefore, when interpolating, the data of the interpolation points must be referenced to the points on the relevant day. The first figure is a block diagram of a conventional deinterleaving system. The TV signal turns into the TV decoder 1 to generate the de-interlaced TV signal output, which is then input to the de-interlacing processor 2 to generate the de-interlaced scanning digital signal = output, which is then input to the scaled digital display processing. Unit 3. ^ Among them, the conventional deinterleaving processor 2 is shown in the second figure. The solution TV signals are sequentially output to the three frame buffers 7, 8, 9, and the data of the three images are temporarily stored. The processing unit 12 is then taken out by the line buffers 10, U. Wang uses the frame buffer | § 7, 8 The data of the three image frames in 9 are de-interleaved (d

Unlace) will then deinterleave the scanned digital signal. The method has the following disadvantages: 1. It uses buffers to store data. 1. Three frame buffers (frame material 'are wasted memory space.) 2. During the de-interleaving process, the 8 and 9 data are put into the line buffer together. Therefore, the processing unit must wait for the line buffer (Line buf fer) 1 0, 11 to move the processing time for a long time. [Purpose of this case] The main purpose of this case is to propose _ deinterlacing scans In-use orders
