Description of the Invention (The present invention is related to the image measurement system), and more specifically, the present invention is about the color image sensor sensor system. The memory buffer used reduces the cost of the 1-line low-shirt-like image sensor. Ϋϋ The image sensing system can be used in many applications — & used in many applications. It can convert scans into Electronic format for printing, printing, and archiving. This electronic format in Α is usually used to scan images of "Na & objects. The scanner is a typical image scanning system and broadcasts" Know ". The object is usually a piece of paper for a book or article, and through the scanning rod of the scanner, ^ 1 can be used to generate electronic or digital images of the paper. Ordering image scanning systems generally include a copy of the paper, ^. The sensor group, Redundancy can be scanned and inserted: use optical method to convert the image, in which the most important component of the sensor module to optically convert the object to be scanned into an image is the image sensor, which at least contains Image sensor light Light sensor array. Each light sensor can generate an electronic signal equivalent to the light intensity reflected by the object to be scanned. The electrical signals generated by all the light sensors are then read out, and then the analog to digital converter will Digitization to generate digital signals or images of the object to be scanned. A linear sensor is an image sensor used in an image scanning system. It includes at least three rows of light sensors, and the three rows of light sensors are indexed above. Each has its own filter. Figure 1A shows a linear image sensor 100, which contains at least three columns of image sensors 102, 104, and 106. The paper size applies to Chinese national standards. (CNS) A4 specifications (21〇 ×; 297 mm) 5. Description of the invention () (Please read the precautions on the back before filling out this page) There are filters with different optical frequencies above each column. For example, column 1 All the light sensors on 02, 1 04 and 1 06 have red filters, green filters and blue filters. Therefore, the light sensor of image sensor 100 is exposed to a white light source. When the scanning object reflects its light, image sensing Three electronic signals will be generated at the same time. The need for auxiliary memory buffers for printed image sensors 100 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs and how to repackage the electronic signals to correctly indicate that each pixel is worthwhile Attention matters. Now refer to Figure 1B. This diagram illustrates a simplified image projection model in which the scanned object Η 〇 passes a lens Π 4 through a color image sensor 1 12 to obtain its image, so the color image The sensor 1 1 2 has three rows of light sensors just like the image sensor 100. The light path shown in the figure indicates that the three rows of light sensors do not receive the same scan row of the scanned object 110 at the same time. Light, because there is a physical gap between the three light sensors, and the distance between the two columns of the light sensor must be reserved for the readout circuit to read the electronic signal of an adjacent column of sensors Therefore, it is necessary to store the electrical signal array obtained by each row of the light sensor. The size of this array is proportional to the distance D between the two sensor arrays. Assuming the distance D is 100, the height of the light sensor is 10, and the signal is expressed in 8 bits, then the memory capacity of a color image is equal to 8 (3D) / d = 240 bits. In practice, color images are often used. The sensor is designed to scan the size of 8 * 1 1 inch standard paper, so if the resolution of the image sensor is 600 dpi, there are 600 * 8 = 4 800 light sensors per column; in other words, memory The capacity requirement of the buffer is 240 * 4800 = 1.152 million bits. This is enough to re-πΑ.π—— This paper size applies the Chinese National Standard (CNS) Α4 specification (210 x 297 mm) 174093 A7 B7 Ministry of Economic Affairs Printed by the Intellectual Property Bureau's Consumer Cooperatives V. Description of Invention () Package the electronic signal so that it can represent each color pixel signal. In addition, in order to maintain a reasonable scanning speed, the performance of the memory buffer is usually required to be high, so the cost of the image sensor will be greatly increased. Although there are limitations in reducing the separation distance, there have been some attempts to reduce the distance in the past. One of these ways to shorten the gap between two rows of light sensors is to shrink the light sensors so that each of the three rows of light sensors can be brought closer together, but unfortunately the light sensor The large reduction of the sensor will cause the problem of image sensitivity. No matter what method is used to reduce the problem caused by the gap between the light sensor columns, in the current light sensor architecture (as shown in Figure 1A), the electronic signal is restored by means of an auxiliary memory register. The packaging method is irreplaceable, so the current color image sensors need to be able to output satisfactory color image signal quality with the smallest memory buffer. Once the capacity requirement of the memory buffer is reduced, the color image The cost of the sensor can be greatly reduced. Object and summary of the invention: The present invention is made in view of the above problems, and can be applied to image sensing devices of scanners, facsimile machines, and photocopiers. As described below, the present invention is particularly suitable for use in image sensors of portable and desktop scanning devices. One of the great features and advantages of the present invention is that the capacity requirement of the memory slow charger is greatly reduced. In one embodiment, the size of the memory buffer can be minimized. Another feature and advantage of the present invention is that double resolution can be achieved when the scanning target is black and white. -msm_ This paper size applies Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling out this page) 174093 A7 B7 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs () According to a feature of the present invention, the disclosed color image sensor includes at least an array of light sensors, and each spaced light sensor has a first type of light transmission characteristics, and each other The light sensor interleaving is arranged by the light sensors of the second light transmission characteristic and the third light transmission characteristic. Generally speaking, the first light transmission characteristic light sensor is sensitive to green light (forming a green signal), the second light transmission characteristic light sensor is sensitive to red light (forming a red signal), and the third is Light transmission characteristics The light sensor is sensitive to blue light (forms a blue signal). Each color pixel is produced by a combination of green, red, and blue light signals. However, one feature of the present invention is that two adjacent color pixels have the same red signal, and the other two adjacent color pixels have the same blue signal ^ so the gap between the light sensors in the horizontal direction is reduced to Minimal, even after the signal from each color light sensor is properly processed, the resolution of the grayscale image is doubled. Other advantages, objects and features of the present invention can be achieved by the following detailed description. The embodiments are described in detail below and will be illustrated in combination.

Color pixels generally include images of three intensities, each of which is made by exposing a three-color element to a color object. One of the commonly used methods for exposing the three-color element is to use an image sensor, which contains at least a plurality of light sensors.

Description of the invention () Multi-selective light-transmitting filter composition for penetrating to the first, second and third groups of light sensors to sense the visible light of red, green and blue respectively Then, the only light that can pass through the filter is red, green, and blue light, so the respective image intensities of the three colors of light can be obtained. In general, the digital grading of each image intensity can range from 0 to 2 5 5 (in terms of 8-bit accuracy). In other words, the color pixel of each color image is a vector pixel, which can be expressed as follows: where (i, j) is the coordinate of an image pixel, C refers to the color image, and R, G, and B are color images The three intensities of C, the above expression can only hold true if all three color intensities of R (i, j), G (i, j), and B (i, j) are available, that is, a color object The intensity of the three primary colors at the same point must be present to form a color point signal. If each of the three image strengths of a cluster of points S has the same value, that is, R (i, j) = G (i, j) = B (i, j), where the (i, j) points fall on S Within, then a certain point in S in a colored object must be colorless. Conversely, if the color intensity of the cluster point S is different, that is, R (i, j) G (i, j) B (i, j), then the color of a point in S in the color file must be visible. For example, pure red, green, or blue vector pixels can be expressed as C (i, j) [255 0 0] TC (i, j) = [0 25 5 0] τ C (i, j) = [Ο Ο 2 5 5] τ. In addition, the color imaging system must be carefully controlled to generate image intensity, and then combine the image intensity to produce the final page 9 (please read the precautions on the back before filling this page)

Description of the invention () Make further changes' to further reduce the demand for memory buffers. The 2D diagram illustrates how to obtain color pixels from the above configuration, without considering the problem of pixel synthesis in the horizontal direction, and it should be incorporated into Figures 2A and 2B for illustration. Table 220 lists 10 maps from Figure 2A Image sensor 20 The color pixel samples of which 10, PI, P2, P3, ..., P 10, and 244, 24 6 and 248 are listed in column 2 4 2 respectively, and the green, red, and blue components of the above pixels are displayed respectively. More specifically, Then, the signal of each green light sensor represents a component of a color pixel, and the red and blue light sensor signal components of the color pixel become a common component of two adjacent color pixels. For example, the color vector pixel P 1 The green light components of P2 and P2 are from two different green light sensors, but the red and blue components are from the same red and blue sensors. Therefore, the horizontal interval between the two color pixels is minimized without causing image resolution. Degree of loss. It should be noted that the above method is composed of red, green and blue light sensors. Those skilled in the art can also use light sensors made of other three primary colors or complementary colors, such as purple, yellow and blue. A set of complementary colors that can be used to generate each color. In addition, interposing a set of green light sensors between alternately arranged red and blue light sensors is not a requirement for implementing the present invention, but it is actually a better practice because the human visual system Green light frequencies appear more sensitive. An example of another image sensor 300 is illustrated in FIG. 3A, which includes at least photo sensors 302 arranged in a row. In the figure, a green filter is inserted next to each light sensor, and a red or blue filter is next to the green filter. The color pixels are placed by this light sensor (2D (Pictured) The 12th page of this paper is applicable to China National Standards (CNS) 8-4 specifications (210 > < 297mm) (Please read the precautions on the back before filling this page) -_ Order Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the employee consumer cooperative 174093 A7 B7 Printed by the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention () Image intensity. Taking advantage of the advantages of such a single-row light sensor, it eliminates the need to store the light sensor into a 3D memory buffer, which is needed to package the signal into an electronic signal. At this time, the signal can be easily read without the signal passing Read the packaging again. The embodiment in FIG. 3B illustrates a single-row light sensor composed of a triangular light sensor. It should be noted here that the triangle referred to here includes various triangle-like shapes, such as a circular-arc triangle. . As shown, few (upward) triangular light sensors have green light sensitive filters (herein referred to as green light sensors) on them, such as Gl, G3, G5, G7, G9 G11 G 1 3, G 1 5, G 1 7 and G 1 9 and upside down triangle sensors such as R2, β4 R6 B 8, R 1 〇, B 1 2, R 1 4, B 1 6, R 1 The red and blue sensors of 8 and B 2 0 are interposed between the green light sensors. With this configuration, the horizontal gap between the light sensors can be minimized. In many applications, 'color image sensors are used to scan colorless objects' or only black and white objects (such as scanning a page from a reference book) and used to generate black and white (grayscale or black and white photo) images. The result of direct reflection from the backlight. In order to ensure that the signal generated by each color light sensor can be equal to the reflection amount of the black and white scanned object, a set of weights is needed to balance the different spectral responses obtained by the color light sensor, as follows: kG 1.967 kR 5.360kB where k is an adjustment factor, and is usually 丨, in other words' green light sensing -------- 13th __ This paper size applies to China National Standard (CNS) A4 specifications (210X 297mm) " 一 ~ " 一-'一-'-(Please read the precautions on the back before filling in this page} Ordering line Γ? 4093 A7 B7 5. Explanation of the invention () °° Signal obtained It can be directly reflected to the final grayscale image, and the red and blue light sense signals must be appropriately enlarged to reflect the final grayscale image. Therefore, in Figure 4, the light sensor scans the object in black and white. It is said that the resolution has been doubled. In a specific embodiment shown in the figure, the value of k is set to 1, r = 196 ?, and b = 5.260, resulting in a grayscale resolution that is higher than that of traditional color image sensors. There is a multiplication effect. Now please refer to Figure 5 A 'to dispense with the image for reading out. The simplified output signal of the signal generated by the light sensor of the sensor 50 2 is 500. The image sensor 502 is 200 or the image sensor of FIGS. 3A and 3B with respect to the image of FIG. 2A. 300 and 31. The multiplexer 504 includes at least a plurality of diodes on and off, and each switch of JL 508 is coupled to one of the light sensors. Diode switch 5 0 8 — The block is controlled by a switch. When the light sensor is exposed to the scanned object, the / control signal (not shown) can control the light sensor to further accumulate the incoming photons, and The charge signal is sent to the opposite storage capacitor (also not shown in the figure). At the same time, the switch 5 08 is then turned on, so the electronic signal in the storage capacitor is then read out to the amplifier 5 1 1. The reading process is performed by the shift register. 5 丨 〇 for this, it usually contains the same number of memory cells as the light sensor. For example, a pulse Di is sent to the displacement register 5 1 0, and D 1 is then transmitted by a storage cell with the clock CLK. To another storage cell. When D1 is received by the storage cell, the connection on the diode switch 50 is opened The close turns on (that is, passes), so the relative electronic signal in the relative storage capacitor is read by the storage capacitor. When Di passes, the electronic signals in the storage capacitor are sequentially shifted out 'and then from an analog to digital converter 5 1 2 for digitization.
