Description of the Invention (/) The present invention relates to an interleaved sensor and method for improving the modulation transfer function, and in particular The invention relates to a father-wrong sensor for lifting the scanning resolution and a method for improving the scanning resolution by using an interlaced sensor. Photo sensors, such as photocopiers, facsimiles, and scanners, which convert visual images into a suitable electronic form for printing, storage, transmission, or other electronic purposes, typically use light sensors, such as charge It is called a charge couple device (CCD) or a contact image sensor (CIS). For tertiary color imaging, the common architecture of these light sensors is an array of CCD elements in three colors: red, green, and blue. Generally, all CCD element columns are exposed for a fixed period of time, after which the induced charges are transferred to the analog shift register and processed subsequently. In order to enhance the resolution on the X-axis (the long axis of the light sensor), the more commonly used method is to interpolate on the X-axis to obtain a data larger than the optical resolution of the light sensor. However, since the size of the sensing cells on the light sensor cannot be changed, the light obtained by the light sensor when scanning is performed. If each sensing cell uses an optical resolution greater than that of the light sensor, it is its actual value. At resolution, the data obtained by scanning will be the average of the luminosity of several pixels. Therefore, if this method is used to enhance the resolution, the performance of the scanner on the modulation transfer function (MTF ′ Modulation Transfer Function) will deteriorate.

Please refer to FIG. 2A, which shows a schematic diagram of obtaining reference digital data in a scanner using an interleaved sensor as a sensor. The arrangement of sensing groups of the same color in the staggered sensor is shown in Figure 2A. The light-sensing cells represented by the diagonal lines represent light-sensing cells that are not used during the scanning process. That is, one way to obtain reference digital data in the present invention is to use digital data obtained from unused light-sensing cells. Please refer to FIG. 1, FIG. 2A and FIG. 3, which show a method of applying an interleaved sensor to improve a modulation transfer function according to a preferred embodiment of the present invention. This method is suitable for scanning to be scanned. On the object 14, the staggered sensor includes at least a sensing group 10 and a sensing group 10 that scan the same primary color.

Here, the range sensed by one light sensing cell is referred to as the number of calculated pixels. Then in step S304, it is determined whether the obtained light-sensing cells are unused light-sensing cells. If so, it indicates that a reference digital data can be obtained as a reference basis, so in step S306, this reference is used. The digital data is written into the buffer storing A (0). After outputting the reference digital data (step S318), another digital data of the light-sensing cell is obtained again in step S302, and then according to this reference 8 books Paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) ---------------- (Please read the note on the back?

Description of the invention ( ;) Examine the digital data and process the digital data of the subsequent calculated pixels obtained when scanning the object 14 to be scanned. In the present invention, a light-sensing cell can scan a plurality of calculation pixels, and from FIG. 2A, the steps of how to use the reference digital data to process the obtained digital data of the calculated pixels can be understood. Because in Figure 2A, there are multiple light-sensing cells that are unused light-sensing cells (slashed parts). Therefore, any one of them can be used as a source of reference digital data. (Eg, light-sensing cell 109) and the unused light-sensing cell (eg, light-sensing cell 128) have a partially overlapping area in the scanning forward direction, so the used light-sensing cell and the unused light-sensing cell The digital data in the overlapping area can be the same digital data. When it is known that the digital data of the used light-sensing cell (light-sensing cell 109) overlaps with the unused light-sensing cell (eg, light-sensing cell 128) (step S308), the process can be performed in step S3 10 In step S312, the reference digital data is read out from the buffer A (0), and in step S312, the following equation is used to obtain the calculation of the scanning of the light-sensing cell 109 that does not have an overlapping area with the light-sensing cell 128 The digital data of the pixels are: A (X) = F (X) * NA (X-1) -A (X-2) -...- A (0) * (NX). For the purpose of reducing the description in this embodiment, taking only one light sensing cell can scan two pixels as an example, it is known from the above equation that the other part of the light sensing cell 10 is scanned. The digital data of A (l) calculation pixel is: A (1) = F (1) * 2-A (0) * (2-1). When the light-sensing cell obtained again (step S302) is not an unused light-sensing cell (step S304) and it is not the same as the unused light-sensing cell 9 ϋ ί i ^ i I ϋ. ^ 1 ϋ -ϋ I n ϋ · I ϋ ϋ n ϋ ϋ 1 1 θ, · I ϋ ϋ ϋ 1 n ϋ I (Please read the precautions on the reverse side before filling out this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 530474 7 7 86tvvt \ doc / 0 1 2 pj B7 V.

Calculate the digital data of the pixel as: A (X) = F (X) * NA (Xl) -A (X-2) -...- A (X-N + l). From this embodiment, A ( 2) = F (2) * 2-A (2-1). Among them, X is the calculation pixel to be obtained, N is the number of calculation pixels included in a light sensing cell, A (X) is the digital data corresponding to the Xth calculation pixel, and A (0) is the reference digital data. , F (X) is the digital data obtained by scanning the light-sensing cells including the calculated pixels. Please refer to FIG. 2B and FIG. 2C, which respectively show schematic diagrams of obtaining high resolution using the interleaved sensor provided according to the present invention. In FIG. 2B, the sensing group 20 and the sensing group 22 are arranged in parallel (for the convenience of description in the following description, the direction of the parallel arrangement is referred to as the long axis), and the light in the sensing group is The test cell 202 and the light sensor cell 222 in the sensing group 22 have one end (204 and 224) at the same position on the long axis and the other end (206 and 226) at different positions. The interleaving sensor proposed by the present invention can increase the scanning resolution, but in order to improve the MTF 値 after the scanning resolution is increased, the implementation steps shown in FIG. 3 can also be used to improve the MTF 値. Therefore, whether it is a conventional or interleaved sensor proposed by the present invention, the acquired reference digital data can be used to improve the MTF 値 after increasing the scanning resolution. 10 (Please read the phonetic on the back?

Explanation of the invention (may) In addition, under the staggered sensor structure proposed by the present invention, the light sensor cell 202 and the light sensor cell 204 can be scanned directly at the same position. By comparing the digital data, you can get the digital data of pixels whose width is the difference between the width of the light-sensing cell 202 and the light-sensing cell 204. In this way, the scanning resolution of the scanner can be improved. , Even if the reference digital data is not obtained, the result of improving MTF 値 can also be achieved. In FIG. 2C, the operation principle is the same as that in FIG. 2B, and the architecture of the staggered sensor in FIG. 2C is very similar to that of FIG. 2B. The difference is that the light-sensing cells 242 in the sensing group 24 are smaller than other light-sensing cells in the sensing group 24, and the light-sensing cells 222 in the sensing group 22 are smaller than the sensing group 22 The other light-sensing cells in it are going to come big. However, these two architectures are the same in operation mode. Both of them use different light-sensing cells (such as 202 and 222, 242, and 262) to obtain different widths than ordinary light-sensing cells.
