Exposure to produce high accuracy and two-intensity sweep signals. ° BACKGROUND OF THE INVENTION There are many applications that require optical scanners to convert paper-like objects, such as text and graphics, into an electronic format that can then be analyzed, distributed, and archived. One of the most common optical scanners is a flatbed scanner, which can convert scanned objects including pictures and paper into images that can be used to build web pages of the World Wide Web and optical text recognition. . Another common optical scanner is the so-called paper-fed scanner, which is small and unobtrusive enough to be placed between the keyboard and the computer screen or integrated into the keyboard. It can also be carried with you as a kind Lightweight cover-up. Most optical scanners are image scanners, and their output is mostly in digital image format. Structurally, an optical scanner generally includes a light signal sensing component that optically converts a document image into a corresponding electronic signal. A typical page 4 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 public director) 丨 ............

Description of the Invention () (Please read the precautions on the back before writing this page) The optical signal sensing component includes an illumination system, an optical system, a An image sensor and an output circuit. The lighting system is used to illuminate the files during scanning. The optical system is used to direct and focus the image light reflected from the document image on the image sensor. The image sensor physically contains many photodiodes, photo-crystals (such as complementary metal-oxide-semiconductor (CMOS) or charge-dissipation element CCD), constituting a subsequent optical signal sensor, which is quite sensitive to incident light 'And an electronic signal called a pixel or charge signal is generated from the optical signal sensor. In general, the pixel signal is proportional to the intensity of the incident light. The stronger the incident light, the stronger the pixel signal will be. The output circuit can be used to amplify signals and convert these pixel signals into digital image formats for further processing when needed. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The operation of an image sensor consists of two steps. The first is the light integration process. The second is the signal readout process. During the light integration process, each optical signal sensor records the incident photons of the reflected light of the document during imaging or scanning, and converts the total number of incident photons into the corresponding number of electronic charges or an equivalent amount. Pixel signal. At the end of the light integration process, the optical sensor will be blocked and no more photons will be recorded. After that, the optical signal sensor starts a signal reading process, in which pixel signals in the optical signal sensor are read out to a data bus or an image bus by a readout circuit. Figure 1A illustrates the internal structure of an exemplary image scanning system 1000. The light source 102 illuminates the scan file 101. The scanning surface 101 can be moved by a moving mechanism or through a full-width optical lens system. This system collects the light reflected from the scanning surface 101 and focuses the reflected light on a page 5 Paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 583875 A7 B7 V. Description of invention () ί ....... »I (Please read the notes on the back before filling this page) Image sense Tester 10 6. Various circuits on the substrate 108 will read the charge signal from the image sensor and output the desired signal. By using the full-width optical lens system 104 and the full-width image sensor 丨 〇6, the image sensing system 100 can perform a full-width scan on the scan file 1 〇 丨. In other words, if the width of the scanned document 101 is 8.5 inches, the width of both the optical lens system 104 and the image sensor 106 is at least 8.5 inches or wider. Today, such optical lens systems use optical lenticular lens arrays, and image sensors are implemented by connecting a plurality of "normal-sized" linear sensors. FIG. 1B illustrates an optical lenticular lens array 120 combined with a full-width image sensor 106 of FIG. 1A. Both need to be customized to fit a specific size of a scanner. As the width of the scanned document increases, the number of linear sensors (ie, 106-1, 106-2, ..., and 106-N) also increases. If the required width of the image sensor is L, then N = [L / N], where □ represents an integer larger than L / n, and n is the size of an ordinary linear sensor. It is generally known in this technical field that connecting several linear sensors will cause additional problems including sensor arrangement, non-uniformity of sensor sensitivity, and signal processing from each sensor. . The complexity of using several linear sensors is inherently difficult to reduce. In fact, the scanned documents can have different sizes, such as printed by A0, A1, A2, A3, A4, A5, A6, B4, B5, B6, C4, C5 and C6, etc., each size requires a scanner with an image sensor of the appropriate size. Different size requirements complicate the design and manufacture of image sensors. Therefore, there is a need for a universal image sensor solution that can be used with scanners of different sizes.

In a specific embodiment, the appearance of the word in various places in the description is not necessarily related to the same specific embodiment, nor will it be excluded from other specific embodiments for independent or alternative specific embodiments. Furthermore, the order of the blocks in the flowchart or illustration that represents the process of one or more specific embodiments of the present invention does not inherently indicate any particular order, nor does it impose any limitation on the present invention. In the illustration, the same parts will be represented by the same numbers. Figure 2 describes the internal structure of a scanning system 2000. Different from Fig. 1a, the scanning system 2000 uses a two-dimensional linear sensor 206. Generally, a linear sensor is considered to be a one-dimensional array of optical signal sensors, but a two-dimensional array consists of arranging the optical sensors within an area. A two-dimensional linear sensor used here is a linear sensor array or multiple optical signal sensors.

Description of Invention In other words, the operation of several linear sensor arrays is synchronized with the movement of the concealed object. According to a specific embodiment, the implementation of the two-dimensional linear sensor is based on the complementary golden semiconductor. Therefore, what is called & CM〇s% image module or CIM 〇 is different from the operation of a line sensor in a traditional scanner, the two-dimensional line sensor 206 will scan a strip of document 101 Part or many columns are imaged at the same time. As shown in Figure 2, when the document is moved forward one by one, the two-dimensional linear sensor 206 will take a strip part of the document 101 or many scanning columns 210 at the same time. Visualization. So the file's The columns are imaged at the same time, and each line on the two-dimensional line sensor is imaged one after another. Using the two-dimensional line sensor 206 in the scanner includes one or more of the following advantages And / or benefits. First, because several arrays of linear sensors scan a file many times, the illumination intensity requirement of the light source 202 is very low. Now an LED can be used to drive the light pipe in a configuration. This configuration uses only the optical lens 204 (instead of a full-width lenticular lens array). In conventional scanners, when equipped with a single linear sensor, a cold cathode fluorescent lamp is often used, which is common in flatbed scanners. The powerful illuminance of a cold cathode fluorescent lamp ensures that a single linear sensor receives a sufficiently strong reflected signal to generate an image signal with a high signal-to-noise ratio. In the case of using a two-dimensional image sensor 206, the reflected signal It does not need to be as strong as a single optical signal sensor, and the sensor 206 can still produce a high signal-to-noise ratio image signal. Second, because the optical lens 9 pages The size of this paper applies to Chinese National Standard (CNS) A4 (210X297 mm) (Please read the precautions on the back before filling this page). ¾. 583875 A7

Description of the invention () All the to-be-scanned columns on the document can be focused on the sensor, so there is no need to connect several such two-dimensional linear sensors to fit the width of the document. Therefore, the problem of having to use a connected linear sensor in a conventional scanner is no longer there. Second, from a design and manufacturing standpoint, a single-size one-dimensional linear sensor is suitable for all situations. In other words, it is no longer necessary to manufacture two-dimensional linear sensors of different sizes to accommodate different width documents. In addition to the requirements for image resolution, a common simplified lens for a two-dimensional linear sensor will make scanners for different scanning needs. Fig. 3 illustrates the configuration of a conventional linear sensor array 302 and the associated signal processing circuit 300. The sensor array 302 may be one of a linear sensor or a connected linear sensor 10 in FIG. 1A or FIG. 1B, and includes a single row of N optical signal sensors. As shown in the figure, each of the 5 tigers is # 1, # 2, ..., #N. During a sweeping process, each optical signal sensor collects the image light projected on it during the integration period and generates an electronic signal. At the end of the integration period, the amplifier array 304 amplifies the electronic signals and samples them individually by a sampling circuit array 306. The multiplexer 308 reads out the amplified and sampled pixel signals successively to become the final continuous image signal output 3 1 0. A register array 3 1 2 controls the operation of the multiplexer 308. The amplifier 314 optionally amplifies the output signal. Referring to Fig. 4 ', this figure illustrates an exemplary sensor configuration according to the present invention. Instead of using a single optical signal sensor array, the sensor 400 uses several optical signal sensor arrays or several linear sensor arrays.

Description of the invention () (Please read the notes on the back before writing this page} The number (M) is greater than 2 and depends on a specific implementation. For example, when M = 5 ' The optical sensors in the first row are arranged along the direction of file movement and are numbered # 1 &,# 1 | 3, # 1 (:, # 1 (1, # 16. In the second row, the light sensors The signal sensors are similarly arranged and numbered # 2a, # 2b, # 2c, # 2d, # 2e, etc. Therefore, the optical signal sensors in the Nth row are numbered #Na, #Nb, #Nc , #Nd, #Ne. It means that one of the features of the present invention is to use several optical signal sensor arrays instead of one optical signal sensor array, and place them at each pixel position along the scanning file moving direction. These optical signal sensors will simultaneously expose the image light reflected from the document and continuously transfer their individual image power. Signal. In order to have a high-resolution scanning operation with high scanning processing capability, each transferred signal is added by means of coordinate to enhance the quality and accuracy of the captured image. During the operation, along the direction of document movement, Set the distance between the center points of two adjacent optical sensor components (equivalent to the optical sensor spacing) to match the scanning resolution. For example, a scan of 600 DPI (the number of points in each frame) The resolution of the Miao Miao means that the distance between the optical signal sensors is 2 5 · 4 mm / 600 = 42.333 micrometers. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, refer to Figure 5, which shows that there are four optical signals in a row. Sensors P 1, P 2, p 3, ρ 4 'Each optical signal sensor is in a different optical signal sensor array. According to a specific embodiment, an image sensor includes M integrated in parallel Array, each array includes N optical signal sensors, so when 0 < i < N, the i-th optical signal sensor in each array (for example, ρ 1, ρ2, ρ3 when μ = 4 , Ρ4) are in series with each other. In fact, for the standard size Document, the range of N is in the range of thousands, and according to the required resolution, page 11 This paper applies the Chinese National Standard (CNS) A4 specification (210x297 mm) 583875 A 7 __B7_ V. Description of the invention () In order to help the operation of the present invention, the scanning resolution will control the M optical sensor arrays to be equal and individually separated by a distance D. (Please read the precautions on the back before filling this page) Wisdom of the Ministry of Economy Printed in Figure 5 by a property co-operative consumer cooperative. A document 500 runs at a controlled speed through the optical signal sensors ρ 1, p 2, ρ 3, and ρ 4. Assume that the file is moved from the left to the right of the picture, so the optical signal sensor ρ4 will expose it first. When a scanning line in the document 500 passes the optical signal sensor ρ4, that is, when the integration is completed, the optical signal sensor ρ4 responds to the light reflected from the scanning line to generate an electronic signal E4 (for example, a light Scan point of the signal sensor). When the scanning column of the document 500 moves to the optical signal sensor ρ3, the electronic signal E4 is first transferred to the optical signal sensor ρ3. When the scanner of the document 500 passes the optical signal sensor ρ3, the electronic signal sensor ρ3 generates an electronic signal Ε3 in addition to the transferred E4 which has been stored in the optical signal sensor ρ3. Now, before the optical signal sensor ρ2 reacts to the light reflected from the self-scanning column (spot) to generate E2, the combined E4 and E3 are transferred to the optical signal sensor ρ2. After the same scan line (dot) passes the optical signal sensor pi, a combined signal E1, E2, E3, and E4 has been generated in the optical signal sensor ρ 1 and can be amplified in the amplifier 502 to A cumulative signal 504 is generated. Those skilled in the art will know that once the electronic signal is transferred from the current optical signal sensor to the next optical signal sensor, the current one will be ready to respond to a new scanning point and generate a new electronic signal. Therefore, the last optical signal sensor has a cumulative signal from the previous optical signal sensor. Therefore, the signal strength of a scanning signal from the accumulated electronic signal will increase several times without changing the moving speed of the document. Especially when M = 10, the scanning signal will be 10 times stronger. The following will show that page 12 of this signal applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 583875 5.
