Abstract

The present invention provides an image sensor having multiple pixel dimensions, which is applied in an image capturing equipment, such as a scanner. The image sensor at least includes a red sensor array, a green sensor array, and a blue sensor array, which are linearly arranged with n red, green and blue sensor cells, wherein the total length of the red sensor array equals to the total length of the green sensor array, and also the total length of the blue sensor array. In order to compensate the defect of insufficient sensing at the edges, the area of sensor cells in each sensor array are progressively increased from the center toward two sides.

Description

541825 V. Description of the invention ο Field of the invention The present invention relates to an image sensor with multiple pixel sizes, and particularly relates to an image sensor with multiple sizes applied in a color scanner. 'It can improve the image quality of the edge field (image field), and can also compensate for the lack of sensitivity in the image sensor. [Background of the Invention]-A scanner is a kind of page, graphic, and illustration that captures images, and even the conversion of coins into a computer that can be displayed, edited, and a scanner can do a lot of work, shapes and photos; input text into typing Scanning and storing fax documents in ^; adding live & to the multimedia, the image data makes it more effective ^ 彳 scanner is an indispensable peripheral device for ordinary personal computers. Device for scanning three-dimensional objects such as photos, text or textiles, and staggered and rotated digital formats. Scan For example: · Combine art graphics in documents and word processing software to save re-entering into the database or word processing for lively and vivid images; express themes in presentations, and so on. For many users or company lines, the view 104 is composed as shown in the figure. It shows the side of the traditional reflective platform scanner. The traditional reflective platform scanner 100 is composed of the cover 1. 〇2 and the base are set to be scanned (not shown). Among them, the light machine with the function of receiving light ^ Ji. T… TV winter talk light source (light source 112, mirror assi s) 1 1 〇 image receiving function 11 541825 V. Description of the invention (2) (reflector) 114, The lens 116 and the photoelectric-sensing device 118 〇 The light source 112 is usually a tube-shaped fluorescent lamp. The light generated by the lens 116 illuminates the document to be scanned 108. After reflection, a reflected light signal is obtained. The reflected light signal may be After multiple reflections by the mirror 1 1 4, the lens 1 1 6 is reached. Then, through the focusing effect of the lens 1 1 6, the reflected light signal can be received by the photoelectric sensor 1 1 8. Then, the photoelectric sensing element 1 1 8 can convert the received reflected light signal into an electric signal for processing, and read out the sensed image data. After the photoelectric sensor element 118 reads the reflected light signal, the optical machine 110 can be driven to move slightly towards the unscanned area by a transmission device (not shown), and the image of the document 108 is sensed again by the photoelectric sensor element 11 8 Then, read out the image data. Repeat the above steps to scan the file 108 step by step. Among them, the photoelectric sensing element 118 is, for example, a Charge Coupled Device (CCD), a Contact Image Sensor (CIS), a metal oxide semiconductor image sensor (CMOS Image Sensor), or other A sensing element that converts an optical signal into an electrical signal. For a transmissive scanner, although the light source located at the flip cover passes directly through the document to be scanned (such as scanning transparent negatives), it also uses the same principle to receive the optical signal through the photoelectric sensor and then convert it into an electrical signal. To complete the scanning action. The structure of the photo-sensing element 1 1 8 (for example, CCD or C M 0 S) is to add a color mask (c ο 1 〇rmask) to the individual perceived grid points (ce 1 1 s) to adjust the color of the grid to the image The sensing ability of the composition. For example, some grid points are covered with a red cover

541825 V. Description of the invention (3) (red mask), called red sensor cells, can detect the red component in the image; other grids are covered with green masks, which are called green sensor grids. Can detect the green component in the image; the remaining grid points are covered with a blue mask, which is called the blue perception grid point, and can detect the blue components in the image. The following is a description of the traditional linear CCD. Please refer to FIG. 2, which illustrates a schematic diagram of a conventional linear CCD. A set of linear CCDs 2000 includes at least a red sensor array 202, a green sensor array 204, and a blue sensor array 206. A plurality of red sensor cells 212, green sensor cells 214, and blue sensor cells 216 of equal area are arranged. The total length (T) of the three-color sensing arrays are all equal. However, in the conventional scanner, the fluorescent lamp used as the light source 1 12 does not emit light uniformly. The light intensity near the middle of the tube is strong, while the light intensity near the sides of the tube is weak. As a result, the light projected by the fluorescent lamp on the original 1 12 is not uniform, so the reflected light signal generated by the document 108 to be scanned is not uniform ', that is, the brightness of the surface of the document 108 is uneven. In addition, when the lens is focused, the reflected light signals on both sides of the document to be scanned will also decay, as shown in Figure 3, which shows the schematic diagram of the optical signal transmitted from the document to be scanned to CCD. Taking point b at the edge of the document to be scanned 308 as an example, the reflected light signal is focused by the lens 316 and then received by the corresponding 13 ′ point on the CCD318. There will be a CG effect, and the middle of the document 308 to be scanned.

541825 V. Description of the invention (4) Between points c, the reflected light signal will not be attenuated. That is, even if the surface of the file 308 has a uniform brightness of 1 ^, (: 〇〇318 has detected that the intermediate brightness of the file 308 is L, but the outermost brightness is attenuated by LX c 〇s4 Θ (& lt L).

From the above, it can be known that the effects of the light source and the lens will affect the efficiency of the CCD sensing (p r f 0 r m a n c e), so that the C C D sensing curve is as shown in FIG. 4, and the two sides show attenuation. The conventional solution is to use a piece of hardware (h a r d w a v e) to automatically multiply both sides of the attenuation by the correlation coefficient (g a i η) to fill the two sides of the curve. However, the disadvantage of this method is that the noise of the optical signals on both sides is also amplified at the same time, which distort the corresponding image. Furthermore, adding components to the scanner to multiply the correlation coefficient will also increase the cost.

Another common problem with image sensors is the difference in sensitivity between colors. Due to the different sensitivity (or response) of the red perception array 202, the green perception array 204, and the blue perception array 206, in general, the grid points are slightly more sensitive to green light than to red Light sensitivity, but the least sensitive to blue light. Therefore, if the same energy is supplied to the grids of the middle area of each color sensing array, the waveforms reflected by them will also be different. That is to say, the contrast capability (Modulation Transfer Function, MTF) of the original manuscripts for the red perception array 204, the green perception array 204, and the blue perception array 206 is not the same. The image cannot faithfully represent the original colors. Even if the color coordinates of the light source are adjusted, the difference in sensitivity between the three colors of red (R), green (G), and blue (B) cannot be compensated.

Description of the invention (5) [Objective and summary of the invention] In view of this, the object of the present invention is to provide an image sensor with multiple pixel sizes, which is applied in an image capture device such as a scanner. One purpose is to compensate for the shortcomings of insufficient edge photosensitivity, and the other is to balance the difference in sensitivity between the three colors of red, blue, and green. According to the purpose of the present invention, an image sensor is provided. The image sensor is installed in an image capturing device.

Description of the invention (6) The total length is equal to the total length of the blue sensing array, and the area of the blue sensing grids is larger than the area of the corresponding red sensing grids, and larger than the corresponding green sensing grids. area. In order to make the above-mentioned objects, features, and advantages of the present invention more comprehensible, the preferred embodiments are described below in detail with the accompanying drawings as follows: [Preferred Embodiments] The present invention has various drawings. One of the main technical characteristics of a pixel-sized image sensor is: in the same primary color sensing array, the pixel size of the edge field of view is larger than the pixel size of the middle field of view to improve the image quality of the edge field of view. Another main technical feature is to make the blue perception array with poor acuity slightly enlarge its pixel size, or make the green perception array with better acuity slightly reduce its pixel size to balance red, green, and blue. Sensitivity between the three colors. The invention can be applied to a variety of photoelectric sensing elements, such as a charge coupled device (Charge Coupled Device (CCD)), a metal oxide semiconductor image sensor (CMOS Image Sensor), or other sensing elements capable of converting optical signals into electrical signals Wait. The following uses a linear CCD as an example to explain the theoretical derivation and embodiments of the present invention. In addition, the perceptual grids in the drawings and the description are described by taking a rectangle as an example, but the present invention is not limited thereto. Theoretical derivation Under ideal conditions, the same light energy is supplied to a linear C C D. For

541825 V. Description of the invention (7) Should be at the end of the edge. The point should be tired: the MO grid point in the taxi field (CM 0 and the CCD grid corresponding to the middle field of view. The middle field of view has the illusion quality. It is expressed mathematically as: P,, pB: Fc = rB / rc = 1 n represents the energy acceptance, which represents the boundary field, (the wonderful symbol C represents the middle Field of view (center f ie id). Relevant and value 1. In the actual situation, Fb / Fc- ° .6, the most sufficient part is multiplied by-(gain), but this method will also amplify noise.) If The mathematical formula (1) of the energy acceptance degree is further deduced: Among them, E represents Lin: Β :: = (Εβχ '" (Ο Ac) (2) represents the energy intensity accepted by the early area in the private point, A Represents the area of the grid point. The term 趄 is due to the difference in the size of the grid area of the CCD, and the difference between the energy density (the area of the conventional grid points is all the same, so that = ㊀ (EB / EC). The lens (Lens) 2 (see Figure 3) in the optical system creates a difference between the center and the edge. Therefore, once the angle

^ (Eb / ec) = cos4 eB / C0S4 ㊀. M γ is changed from the distance from the mirror to the file and the CCD on the linear CCD according to the third figure. However, in general applications, the distance between the m-lens of the household hall and the CCD is a fixed value, so that the selected half-denier angle Θ of the selected grid point is a certain value, so (VEc) is also a certain value. 'want

Make fb / fc reach the ideal time ratio of 1, so that the area in the variable equation (2) = 1 / (eb / Ec) Therefore, from the above inference, we can know that, 4; magnetic responsibility to p 4 by adjusting the t point The size ', that is, changing the pixel size of k, can compensate for the diurnal angular force I7. The acceptance of the change is close to φ Μ Zhao P. The sound makes the edge field of view can be similar to the middle field of view. The first embodiment is located in the CCD. The center grid point at the center is at the outer edge grid point. Suppose that 0, C 'is located at the most sigh + day angle ㊀b = 45. , Then equation (3) is: (EB / EC) = C0S4 ㊀b / c〇s4 ㊀ 1/4 Substituting into equation (4), we get: (Ab / Ac) = 1 / (1/4) = 4 So 'if If the area of the outermost edge grid point is increased to 4 times the area of the center grid point, two grid points with different positions will have the same energy acceptance. As for the area of other grid points, the closer the grid point to the center is, the smaller the corresponding diurnal angle is, so that the area ratio obtained by equation (4) is smaller. Therefore, the change of the grid area (day prime size) is that the grid located at the center is the smallest, and the grid area that is more outward is larger. As shown in FIG. 5, it illustrates a schematic diagram of an image sensor with multiple pixel sizes according to the first embodiment of the present invention. A set of linear CCD 500 of the present invention includes at least a red censor array 502, a green censor array 504,

Page 11 541825 V. Description of the invention (9) and a blue sensor array 506, which are respectively arranged by an equal number of red% green and blue sen s or cells 0, where the area of the perceptual grid in the red perceptual array 5 0 2 gradually increases from the center perceptual grid 5 1 2 to both sides, so that the area of the edge perceptual grid 5 2 2 is the largest. Similarly, the green perceptual array 5 The area of the perceptual grids in the 0 4 and the blue perceptual array 5 0 6 is gradually increased from the central perceptual grids 5 1 4 and 5 1 6 to both sides, so that the areas of the edge perceptual grids 5 2 4 and 526 are the largest. It is worth noting that although the present invention compensates for the influence of the half-drawing angle on the energy acceptance by changing the area of the perceived grid points, the total length of the three-color perception array must be maintained equal (Ί \), and the three-color perception grids The number needs to be equal to 0. The number of perceptual grids is related to the resolution. For example, with a scanner with a resolution of 6 0 dp i, the number of grid points required to scan a file of length 8. 5 inch is 5100 points (8.5 (i η) X 600 (dot / in) : = 5 100 (dot)) 1. Therefore, each of the three sensing arrays of red, green, and blue requires 5,100 sensing grid points. In the first embodiment, the area of each grid point is changed according to the corresponding half-drawing angle, and the actual CCD grid point is 0. The area is very small. Even if there are dozens of adjacent grid points, the change of half-angle is very small. Therefore, in practical applications, all grid points can be divided into several parts to achieve the effect of compensating the half-angle. 0 In this embodiment, all grid points are divided into corresponding two fields of view. ^ FIG. 6 shows a display device according to a second embodiment of the present invention.

Page 12 541825 V. Description of the Invention (ίο) A schematic diagram of an image sensor with multiple pixel sizes. A set of linear CCDs 600 in FIG. 6 also includes a red sensing array 6 0 2, a green sensing array 6 0 4, and a blue sensing array 6 0 6, and each sensing array is composed of equal numbers. The red, green, and blue perception grids are aligned. Among them, each sensing array can be divided into three corresponding fields of view with the center line 0 as the optical center.红色 For the red sensing array 602, when the field of view is larger than the Η field of view, the long side of the red sensing grid is a and the wide side is b. When the field of view is smaller than the field of view and larger than the field of view of G, the long side of the red sensing grid point is a 'and the wide side is b'. When the field of view is smaller than the G field of view, the long side of the red sensing grid is a '' and the wide side is b ''. Similarly, for the green sensing array 604, when the field of view is larger than the Η field of view, the long side of the green sensing grid is c and the wide side is d. When the field of view is smaller than the Η field of view and larger than the G field of view, the long side of the green sensing grid is c 'and the wide side is d'. When the field of view is smaller than the G field of view, the long side of the green sensing grid is c '' and the wide side is d ''. For the blue perception array 6 06, when the field of view is larger than the field of view, the long side of the blue perception grid is e and the wide side is f. When the field of view is smaller than the Η field of view and larger than the G field of view, the long side of the blue perceived grid point is e ′ and the wide side is f ′. When the field of view is smaller than the G field of view, the long side of the blue sensing grid is e '' and the wide side is Γ '. In this embodiment, the area of the sensing grid located outside the sensing array is large, and the area of the sensing grid located at the center of the sensing array is small, as shown in the figure. Taking the red sensing array 602 as an example, the change in area can be fixed on the wide side and the long side can be changed, that is, let b'b '= b' ', a > a' > a ''. Or fix the long side so that

=! Hua: Let a = a ’= a ,,, b > b, > b ,,. The long and short sides can also be the same = change 'so that ab > a'b' > a ', b ,,. It is worth noting that the relationship of a = c = e, a, = c, = e ,, a -c = e '' is maintained among the red, four-color, and blue perception grids. 1 Ran 'is limited to the change of painting only in the corresponding 3 people's field, and the corresponding field of view can be 2, 5, or even more. As long as the perceptual grid is equal to the corresponding field of view, which is a positive integer, it is gradually increased from the outer side of n to compensate for the lack of sensitivity of the edge image. This is the technical feature of the present invention. In addition, the details of how to use the diurnal dimensional change of the present invention to balance the sensitivity differences among the red, green, and blue sensing arrays are described below. Due to the difference in light transmission between the green, red, and blue masks, the sensitivity of the perceived grid to green light is slightly better than the sensitivity to red and blue light ^ ', and the sensitivity of the perceived grid to blue light As the lowest. Therefore, the grid points of the second, middle, and chromatic sensing arrays can generate strong electrical output signals. The present invention is to adjust the area of the perceptual grid points in the three-color array to balance the difference in the three-color sensitivity. Taking Figure 6 as an example, if we do not consider the problem of insufficient sensitivity of the edge image, the area of the perceptual grids that make up the same color is the same, that is, a = a '= a' ', b = b, = b ,, , C = c, = c ,,, d = d, = d ,,, e = e, two e ,,,

Explanation of the invention (12) f = f, = f9 9, in order to solve the problem of different acuity, the present invention can amplify the blue perceptual array with poor acuity by slightly amplifying the size j of its perceptual grid point, and it is sharp. The better-perceived green perception array slightly reduces the size of its perceptual grid, that is, ef > ab > cd 0 when it is wonderful; it can also fix the long side 1 and only change the short side, that is, a = c = e? F b > d 0 In the fourth embodiment, in addition to the dimensional changes between pixels for the two-color sensitivity in the third embodiment, the problems of insufficient sensitivity of the edge image and different two-color sensitivity can also be improved. In this embodiment 1 except that the center of the area of the perceptual grid of the same color gradually expands to both sides, the area of the green perceptual grid is also smaller than the area of the corresponding red perceptive grid and the area of the corresponding blue perceptual grid is the largest. The figure is an example, that is, a b > a, b, > ab, 9, cd > c 'd, > c,, d,, ef > e' f '> e,, f,,, and ef > a b > ^ cd 0 Pixels * Ruler 'Inch' is adjusted by 1: 1: not only can improve the image quality of the edges, but also balance the sensitivity of the red, green, and blue sensing array to make the two-color sensing array respond The contrast ability of the manuscript (M od u 1 ati η Tr an sferf unci:; i on, MTF) is approximately equal, so the images obtained by scanning can faithfully present 0. CCD includes red (R), green (G), and blue (B) two-color sensing arrays as examples for illustration.
