(4) When the image is used, the image must be inserted into the image of the image. When input image A is enlarged and wants to generate inclusion B, when the rich man wants to input the ^ ϊ A, it must be _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The method finds the value of the new pixel point. Ordinary techniques or virtual distance parameters are interpolated to produce the desired interpolation points. m, J: 'The method of generating these defects' actually requires the hard-wired circuit of the Wei n to increase the manufacturing cost of the digital image display and affect the efficiency of adjusting the image. Inch 338279 Therefore, if you can create an interpolation point without additional hardware calculation circuit, you can increase the adjustment number "speed of image" to reduce the production cost of the digital image display, so you can solve the above problem. SUMMARY OF THE INVENTION The object of the present invention is to provide a method for generating a output image by performing an internal (four) calculation on an input image by providing a value of _, a value of sulphur, and a sulphur value according to a comparison value. The hardware calculation circuit without the meal can determine the position of the interpolation point, which not only reduces the manufacturing cost of the digital image display, but also improves the speed of the image adjustment, thereby improving the performance of the digital display. The image adjustment circuit of the present invention comprises a vertical interpolation circuit and a horizontal interpolation circuit, wherein the two interpolation circuits each comprise a plurality of data shift cycle circuits, a controller, a selection unit and an operation circuit, and each data shift cycle The circuit stores a plurality of data flags. When the (four) shift cycle circuits are driven by the controller, the data is sequentially outputted by the controllers; (4) the device is based on the input image-original dependence and the target The age H is saturated with one of the selection signals and a driving signal, the driving signal is used to drive one of the data shifting loop circuits, and the selection signal is sent to the selection unit, and the hybrid unit selection tank corresponds to _ Interpolating the control value, the interpolation control value corresponds to the driven data shifting loop circuit; the arithmetic circuit sequentially interpolates the input image according to the data flag and corresponding to the interpolation control value, and generates a corresponding target display One of the resolutions outputs the image. The method for interpolating the image adjustment circuit of the present invention mainly comprises: selecting one of the corresponding interpolation values and the plurality of data flags according to an original resolution of an input image and a target display resolution; and sequentially according to the The data flag and the interpolation value should be interpolated, and the input image is interpolated to generate an output image corresponding to one of the target display resolutions. [Embodiment] Please refer to the second circle, which is a block diagram of the image adjustment circuit of the present invention. As shown, the image adjustment circuit 10 includes a detection circuit 12 for detecting an input image to know the original resolution of the input 6 1338279 image and transmitting it to the - vertical interpolation circuit 14 and the horizontal Then, by using the image adjustment circuit 1G's #直_circuit 14 and the horizontal 嶋 circuit π, according to the original resolution of the image into the image and the target age resolution, the interpolation operation is performed on the input = To produce a (four) key image that conforms to the resolution of the target display, the display unit 18 displays the image. 4 The vertical interpolation circuit 14 will calculate the vertical resolution of the original resolution of the input image and the vertical resolution of the target resolution (the fourth). Then, the vertical interpolation circuit 14 transmits the new pixel data to the horizontal interpolation circuit 16, and causes the horizontal interpolation circuit 16 to perform _ calculation on the horizontal level of the new data according to the horizontal resolution of the target display resolution. And produce an output image that matches the target display resolution. Since the image resolution generally used today is mostly a certain degree of resolution, for example, the horizontal resolution is 640, 720, 800, 1024, 1152, 1280, and 1440, and the vertical resolution is 350, 400, 480, 600, 768, 864, 900 and 1024, etc., so the present invention pre-establishes complex interpolation control values according to the several resolutions, so that the vertical interpolation circuit 14 and the horizontal interpolation circuit 16 compare the corresponding interpolation values. Interpolation operation, so that the position of the interpolation point can be known by comparing the interpolation control value without further calculation, so that the problems encountered by the conventional technology can be solved. As shown in Table 1 below, it is an interpolated control value of a preferred embodiment of the present invention. 1338279 original resolution 1024- target display resolution 1280

As the table - the *, this Nei Linsi is flat and wants to adjust to it. The _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The interpolation control value of the present invention is established by the first scale factor and the second scale factor. The product of the original resolution and the -th factor is equal to the product of the visualizer resolution and the second proportional factor. The first-scale factor and the second-factor are interpolated in the interpolated control values, and the number of resources and the sampling point interval information (table - not shown). The first-scale factor and the first-scale factor of the interpolation control value of the table __ are 1〇 and 8, respectively, that is, the dish side is equal to χ8. The number of interpolated points, the number of information is the number of data per input. Taking the table-input control value as an example, the mother's original horizontal pixel point must be adjusted to expand to the pixel point. The so-called sampling interval information is the number of intervals for sampling the adjusted pixel points; the interpolation value of the third figure is taken as an example. Since the interpolation point_information is 8, that is, a point is sampled every 8 intervals. As shown in the sampling point information and output point information of the interpolated control value in Table 1, the first output point is also 1338279, which is the first point of the pixel point after the first sampling point of the first sampling point; The second output point is also the second sampling point, which is the 9th point of the pixel after the adjustment of the i-th original image plane, the first sampling point and the second lion __8, that is, the separation information The third output point is also the third sampling point, which is the third point of the pixel after the second original pixel is sampled and adjusted. The 鸠p signal of the present invention is related to the output point information " ^ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ That is, 1(): 8, so every time after 8 interpolated pixels, the 9th pixel is sampled, and the pixel corresponding to the sampled pixel is on the 9th pixel. In this case, when it is inserted into the fairy insertion operation, the system skips 8 __ to detect the data loop, that is, skips the pixel after 8 _, and then obtains the output point according to the table _ operation and then skips. Eight interpolated prediction data, the last last data is the i-th starting data of the subsequent interpolation, that is, the i-th starting data of the subsequent sampling is taken as the feeding material. In addition, the recurring point of the dragon value towel is called _ the pixel remaining after the original pixel point. After the sampling point position is known, the interpolation operation is performed according to the corresponding operation point information, so as to know that the sampling point is ">_, the value of the sample is based on (4) the red operation point resource «Λ (1) The value obtained by the interpolation operation is that the operation point information of the i-th sampling point is 1, that is, the value of the first sample point is the value of the image. The operation point corresponding to the second sampling point is tflg 1,2, which means that the second sampling age between the pixel and the second original pixel is 'the second value of the lion will be woven. It is known that the value of the strong pixel and the second original pixel are interpolated. In addition, when performing the interpolation operation, the weight value corresponding to the sampling point must be known to obtain the value of the sampling point using the interpolation equation. According to the sampler's information-weight comparison chart, Benfa Qing knows (4) the weight value, and calls the person to insert the money to calculate the value of the sampling point. The weighting method corresponding to the interpolation method is not The same, commonly used interpolation method has linear interpolation method (Lineai* interpolation), sine function interpolation method (5) 叱 9 1338279

It is assumed that the operational interpolation of the present invention performs the 秘 operation to know the value of the output point. When _ computing the i-th output point, '镰 the first sampling point of the sampling point information (1) and the weighting comparison chart can be found that the corresponding weight value is 1, · interpolating the second round of the heart, hiding According to the sampling point information corresponding to the second output point (8) and the weight comparison _ can be found that the corresponding weight value is 〇. 11; similarly, when calculating the remaining output points, according to the corresponding sampling point f The corresponding weight value can be known by comparing the weights with the chart. Since the _ control value of the present invention is established by the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The invention of the present invention can be Wei Long. In the example of the third figure, after the _ xiang 5 lion training, the health and reward points are shown in the 7th adjusted pixel, and the 6th sampling point is used as the continuation. Insert the i-th starting pixel point, and the 6th sample of the remaining image will be the 5th original pixel point, so the 5th silk pixel point can be used as the connection. Calculate the first original pixel point, and then perform the interpolation operation according to the interpolation control value. The starting point of the ring of the above-mentioned interpolated control values will vary with the ♦ riding degree, that is, the starting point of the cycle will be different. · In the present invention, since the complex interpolation control value is provided in advance, when the interpolation operation is performed, the corresponding information can be immediately compared with the interpolation control value, so that the input image can be interpolated and the image is output. The adjustment circuit for adjusting the image can be simplified, the cost of calculating the electric circuit can be reduced, and the efficiency of adjusting the image can be improved, and the interpolation operation can be performed by cyclic comparison. In addition, since the information in the interpolation control value of the present invention is an integer, the operation can be simplified when performing the interpolation operation: thus, the interpolation operation can be performed without using a complicated operation circuit, so as to increase the total cost ^ It

The interpolation circuit 20 of the fourth embodiment is applied to the horizontal interpolation circuit 16 (refer to the second figure). Therefore, the data stored in the image line register 90 is the vertical internal subtraction 14 (refer to the second special delivery). The image data generated by the arithmetic circuit 70 is transmitted to the display unit 18 and displayed. The interpolation circuit 2 used in the vertical interpolation circuit 14 and the image temporarily stored in the image line register 9 (4) The image line temporarily stored in the horizontal interpolation circuit 16 is sent to the horizontal interpolation circuit 16 and transmitted to the horizontal interpolation circuit 16 for transmission to the display object material to be displayed on the display. In addition, the arithmetic circuit 7 of the vertical interpolation circuit 14 is configured to select a corresponding slit according to the vertical resolution of the original resolution of the input image and the vertical resolution of the target display resolution. The value of the value and the data flag, and the level of the original scale of the horizontal interpolating circuit 16 and the level of resolution of the target display are selected to correspond to the interpolated value and资龙标广', ' See Figure 5 is a flow chart I of a preferred embodiment of the present invention, such as a ride-by-image adjustment method. First, as shown in step SQ, a complex interpolation is performed on a complex-valued complex array of dragon flags, each group of flags. All of them include a plurality of data flags, that is, a dragon flag stored in a plurality of Becco shift circuits; after that, the circuit 12 performs the === input image to know the original resolution of the input image and transmits it to the controller. The following step, the tearing step S2 'based on the original riding degree of the input image and the target display ϋ analytical production ' == 目龙的面讯_咖_聪 unit 60 and scale _ position and one of the ring road 40, to Selecting the corresponding interpolated control value and the complex data flag. The scanning circuit 7G performs step S3, sequentially interpolating the wheeled image according to the dragon flag and comparing the interpolated pair value to generate a conforming target display. The resolution circuit avoids the timing of the output of the panning and tilting circuit 40 to output the flag. The circuit 70 has no timing for calculating the input image, so when the circuit is generated, the clock generates II 8G to generate synchronization. Pulse signal two 'output _ road 4G, New Zealand squama signal output in order _ (4) The calculation circuit 7G synchronizes the input image according to the synchronization noise signal according to the flag and the = 12 1338279, and calculates the input image to generate the output image. In summary, the interpolation circuit of the image adjustment circuit of the present invention and The interpolation method is based on the resolution of the target display and the original resolution of the input image, and the driving signal to the selection material and the reset loop circuit, "the illuminating value and the complex number (four) flag, so that the arithmetic circuit is sequentially Selecting the value of the interpolated value, • Interpolating the image =====Interpolating the image, so that the image can be quickly and difficult to be imaged, and the material of the can is improved.
