In addition, mobile devices are small-sized, small-sized, and small-sized, and the images are reduced. Therefore, for example, when the recorded text is displayed on the display device, the text may be displayed incorrectly because it may be too small. SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and an object thereof is to provide an image magnifying device capable of clearly magnifying and displaying an image captured by an image. In order to solve the above problems, an image enlargement device according to an aspect of the present invention includes: a first display unit having an image capture function and a display function 1 image enlargement unit, wherein the enlargement processing is performed by the second display unit And a second display unit that displays an image that is enlarged by the image magnifying unit; the first display unit includes a second display element that is located in the signal line and the scan line formed in the mediastinum a pixel in the vicinity of each intersection; an image input unit that is provided for each of the second display elements and that captures a specific range; and a first signal line drive circuit that drives the signal line connected to the first display element And a Uf trace driving circuit that drives the scan line connected to the first display element; and the second display unit includes: a second display element formed near the intersection of the signal line and the scan line arranged in the vertical and horizontal directions, and can be displayed An image-amplified second signal line driving circuit that is amplified by the image magnifying portion, drives a signal line connected to the second display element; and a second A scanning line driving circuit that drives a scanning line connected to the second display element. Furthermore, an image magnifying device according to an embodiment of the present invention includes: an image capturing unit that captures an image; and an image magnifying portion that is enlarged to have a backlight device between the substrate and the substrate 89929.doc 1277937 4 6. The video amplifying device of FIG. 1 , for example, the mobile phone 7 built in the mobile phone 7 shown in FIG. 2 includes an operation panel substrate (the first substrate) 8 and a display substrate (second substrate) 9 which can be The hinge 1 is folded for the shaft and can be opened up to 180 degrees as shown in FIG. Recent folds: ^: The type of mobile phone has more female face and child picture, the figure of Figure 1 is like the magnifying device! The display unit 3 corresponds to a sub-screen, and the second display unit* corresponds to a parent side. Hereinafter, an example in which the image enlargement device of Fig. 1 is used for the foldable mobile phone 7 shown in Fig. 2 will be described. In the mobile phone 7 of the present embodiment, the captured video can be displayed in an enlarged manner. In this case, the i-th display portion 3 is brought close to or in close contact with the image-like object to start image capturing. Thereby, the captured image is enlarged and displayed on the second display unit 4 in real time. That is, the image enlargement of this embodiment does not have the function of a so-called electronic magnifying glass. In the yoke shape, since the image magnifying device of the image is placed close to the image pickup object, there is no need to fix the image magnifying device, and there is no problem that the image is blurred due to the vibration of the hand. One of the specific uses of the image magnifying motion according to the present embodiment is for an elderly mountain or a premature person. For those with low vision such as elderly or visually impaired, it is extremely difficult to recognize small words. If there is a large magnifying glass on hand, then: minus: it is hard, but you can't carry a large magnifying glass with you. Therefore, when you suddenly need to recognize small texts at the f仃di temple, you will feel extremely bad: for example: 'Getting at the place of travel Booklets, timetables and maps, etc., so that the big tribute is recorded on a limited paper, so the font size is mostly smaller than 92929.doc 1277937. Older people or visually impaired people may not be able to recognize the text, or spend a lot of money. Time can recognize the text. In the image magnifying device of the present embodiment, since the video amplifying device is built in the mobile phone 7 held by the public, the video can be easily enlarged if necessary, even if the large magnifying glass is not carried with the user. Accurately recognize small graphic information. Further, since the electronic magnification can be changed as needed, and the focus is not required to be adhered to the paper surface, the user can use the magnifying glass more conveniently than a normal magnifying glass without having to focus on the focus. The first and second display portions 3 and 4 of Fig. 1 are flat display devices such as a liquid crystal display device or an EL (Electroluminescence) device, and the circuit configuration of the display function can be formed by a well-known person. FIG. 4 is a view showing an example of a plan layout view of the second display unit 3. As shown in the figure, the first display unit 3 includes a pixel array unit 21 in which a signal line and a display line are arranged, a signal line drive circuit 22, a (four) signal line, and a scan line drive circuit 23 that drives the scan line; The sensor control circuit 24 controls image capture; and the signal processing output circuit 25 performs image processing after image capture. These circuits can be formed on a glass substrate by, for example, a polycrystalline silicon transistor (Thin Film Transistor) using a low temperature polysilicon technology. By forming the first display portion 3 by using a polycrystalline germanium TFT on the glass substrate, the entire second display portion 3 can be formed on the same glass substrate, thereby achieving small ploughing and preventing static electricity or mechanical damage. Fig. 5 is a circuit diagram showing an example of a detailed circuit of a pixel portion of a pixel array portion. Each pixel includes a pixel TFT 3丨 as shown in FIG. 5; display control 92929.doc -10- 1277937 TFT 32 'which controls whether or not the charge is stored in the auxiliary capacitor & the image pickup sensor 33; the capacitor c, the image capture result of the image capture sensor; SRAM 34, which stores the stored charge corresponding to the capacitor buckle 2, the material 'initialization TFT 35' is used to store the initial charge in the capacitor benefit c 1 ; and data retention with TFT 3 6. In Fig. 5, the number of H U-like pickup sensors 33 for setting i image pickup sensors 3 3 for each pixel is not particularly limited. The more you increase the shadow of each pixel (four) should be! The number of ^3 can increase the resolution of image manipulation. The first "No" 43 can perform the normal display operation, and can also be imaged with the scanner 5 5V. When the normal display operation is performed, the initializing = TFT 35 and the lean material holding TFT 36 are set to the off state, and the effective data cannot be stored in the buffer. In this case, the signal line is supplied with the signal line from the signal and the pillow packet 22, and the image light corresponding to the voltage of the signal line is applied.

Fig. 6 is a diagram showing an example of a mobile phone 7 in which the video enlargement device of the embodiment is not built. Ghost map, a schematic diagram of a mobile phone 7 with no camera attached. The mobile phone 7 of FIG. 6 includes: an LCD (UqUid Crystal Display, 92989.doc -11 - 1277937 liquid display) substrate 41, which includes the above image magnifying device; The liquid crystal device (hereinafter referred to as LCDC) 42 is mounted on the LCD substrate 41; the baseband LSI 43'·camera 44; the image processing 1C 45, which performs image processing of the image data of the camera 44; the transceiver unit 46, and the base station Communication is performed; and a power supply circuit 47 that supplies power to each unit. The baseband LSI 43 includes a CPU 5 main memory 52, an MPEG processing unit 53, and a DRAM 54, which control the call of the mobile phone 7. The LCDC 42 includes: a control unit 55'·sub-frame memory 56, the agricultural storage should be displayed on the pixel data of the reading unit 3; and the mother screen (4) the memory 57' should be stored in the second The pixel data of the display unit 4. The coffee c42 is used to display the display for controlling the image captured by the i-th display unit 3 to be enlarged and displayed on the second display unit 4. Fig. 7 is a flowchart showing the procedure of the display control processing of the second display unit 4 by the LCDC 42. First, the discrimination operation mode is the normal display mode or the image manipulation mode (step S1). In the case of the normal display mode, the image of the image f to be displayed on the screen of the second display unit is written in the mother's face = frame memory (step S2). Next, the pixel data of the water-repellent line to be displayed on the second display unit 4 is read from the mother-side frame memory and subjected to d/a conversion (step S3). Next, 'the analog video signal is written to each pixel (step S). Thereby, the second display unit 4 is displayed for each horizontal line. Next, it is determined whether or not the writing of one screen portion is completed (step S5). On the other hand, if the image capture mode is determined in step S1, the first display unit 3 starts image capture (step S6). The image 92929.doc 1277937 is written into the sub-frame memory 56 (step S7). Next, the enlarged image after the captured image is enlarged according to the pre-specified magnification is written into the parent-side frame memory ( Step S8). Then, in the same manner as steps S3 to S5, the display is performed on the second display unit 4 every horizontal line (steps S9 to S11). In the above step S8, for example, when the captured image is enlarged to n times. , · Simply make each pixel data repeat n pixels. Or, you can also smooth it. - You can also prepare to store the enlarged frame memory, and instantly switch the enlarged image to the original size image. Image capture due to the embodiment The input device 33 outputs binary data, and thus the performance gradation cannot be performed. Therefore, in the present embodiment, multiple image captures are performed under a plurality of imaging conditions with different imaging times, and imaging is performed according to each imaging condition. The data is generated in a multi-tone data. The processing for generating the multi-tone data is performed by the LCD C 42. Fig. 8 is a flow chart showing an example of the processing sequence of the multi-tone data generated by the LCD C 42. First, the imaging conditions are changed. And the image capturing is performed by the image capturing sensor 33 (step S21). Then, according to the formula (1), the simple average value of the image data of the different order is counted (step S22). Here, L (x) , y)i represents the gradation value of the i-th coordinate (X, y). L(x, y)=4[L(x,y) i ...(1) 丄5 i=l In the processing of S21 and S22, as shown in Fig. 9, the gradation values are sequentially added and successively added, and successively added to the Nth time, and then divided by ν. In the successive addition process, it is not necessary to retain the added calculation. The camera data. In the case of the sequential addition of Figure 9, the frame memory 丨6 only needs 92929 .doc 1277937, the capacity of the image data can be stored for about 2 times, and the memory capacity can be reduced. Next, the subtraction pattern subtraction process is performed (step S23). Then, white balance adjustment or defect correction is performed (step S24) In this embodiment, since the image captured by the first display unit 3 is displayed on the second display unit 4 in an enlarged manner, the fine text information can be grasped even without the magnifying glass. The image enlargement device can be easily built in the mobile phone 7 or the like, and is particularly convenient for elderly people or visually impaired persons. In the above embodiment, the first and second display portions 3 and 4 are arranged opposite each other. 'However, the i-th and second display portions 3 and 4 may be provided on the same surface side. (Second Embodiment) In the first display unit 3 described in the first form of sorrow, the image capturing sensor 33 is formed inside each display pixel. However, the image sensor 33 may be used. The display pixels are set differently. For example, FIG. 1 is a cross-sectional view showing an example of an image magnifying device provided with an image input unit 62. The image input unit 62 is provided with image capturing separately from the image display unit 61 for performing pixel display and image capturing. Sensor 33. The image captured by the image input unit 62 is displayed on the image display portion 61 in the same manner as in the first embodiment. The video display unit 61 and the video input unit 62 of Fig. 1 are formed on the same glass substrate using, for example, a polysilicon TFT. In the case of image capturing in the image forming apparatus, the display surface side is directed toward the object to be imaged, and the image display unit 61 cannot be viewed while the image is being captured. However, since the image display unit 61 and the image wheel human portion 62 can be formed on the glass substrate, the thickness can be reduced and reduced. Also, it can fit the image input more closely. The image capture sensor 33 in P 62 can improve the resolution of image capture. On the other hand, Fig. 11 is a cross-sectional view showing an image magnifying device in which the backlight unit 63 is disposed only on the image display unit 61. When a light-emitting device such as an el element is formed in the image input unit 62, a backlight device is not required, and thus the image-capturing object can be placed in close contact with the image input unit 62. As long as the configuration is tight, the resolution can be improved. Further, when the backlight device is provided, in order to directly input the reflected light from the object to be imaged into the image input unit 62, it is necessary to provide an optical system of equal magnification. If these optical systems are not provided, the image will be blurred due to the scattered light of the object to be imaged. The optical system of the equal magnification can be realized by providing a lens by the image capturing sensor 33 in the image input unit 62, and the cylindrical mirror can be formed by photo-processing with a resin or the like, thereby focusing on a small area and being highly precise. Capture images from the ground. Fig. 12 is a modification of Fig. 11 in which a front light device 64 is disposed directly below the image input portion. By the front light device 64, the image pickup object is irradiated and imaged, so that a more vivid image can be obtained. The calender device 64 is attached to the glass substrate (circuit substrate) 65 adjacent to the backlight device 63. The front light device 64 and the backlight device 63 include an LED disposed at an end portion, a light guide through which the light of the LED passes, and a ridge that reflects light passing through the light guide. In the front light device 64 and the backlight device 63, 92989.doc -15-1277937 is 180 degrees out of the direction of the light reflected by the pupil. Fig. 13 is a view showing a backlight unit 66 provided in place of the optical device 64 of Fig. 12 . The backlight unit 63 for the image display unit and the backlight unit 66 for the image input unit are attached to the front and back surfaces of the same glass substrate, respectively. As described above, in the second embodiment, since the video display unit 61 and the video input unit 62 are formed on the same substrate, the pixel structure of the video display unit 61 or the video input unit 62 can be simplified. Further, since the arrangement position of the front light device 64 or the backlight device 66 is improved, the captured image can be displayed immediately. (Third Embodiment) In the third embodiment, a foldable mobile phone or the like is considered, and an image captured by an image can be easily viewed. Fig. 14 is a view showing a third embodiment of the image magnifying device, showing a side view of the foldable mobile phone. The image enlargement device of FIG. 14 includes: a first display unit 3 having a display function and an image capture function; a second display unit* having only a display function; and an i-th folding that can be folded with the hinge portion 1〇 as an axis And the second substrate 8.9. The second display portion 4 is provided inside the first substrate 8, and the first display portion 3 is slanted outside the second substrate 9. The second display unit 4 is hidden from the surface when the mobile phone is folded, and the first display unit 3 appears on the surface when the mobile phone is folded. The size of the face of the ^, and the gossip 4 is larger than that of the first display unit 3, and the captured image obtained by the image capture by the first display portion 3 can be enlarged. Further, the first and second display units 3 and 4 can display various images. When the image capture is performed in the mobile phone of Fig. 4, the second substrate 9 is placed in close contact with the object to be imaged, or is placed substantially parallel to the image object 92989.doc 1277937. The captured image captured by the image capturing sensor in the first display unit 3 is displayed on the display unit 4 of the second display. However, the angle of the first substrate 9 can be arbitrarily changed even during image capture, and thus the image is used. The image can be imaged by adjusting the angle of the first substrate 9 to the most easily recognizable angle. As described above, in the third embodiment, the second substrate 9 can be tilted to an arbitrary angle while the image is being captured by the sensor in the second display unit 3, so that the second display is displayed in the second substrate 9. The image of the display unit 4 is displayed. This embodiment is applicable to a large paper surface such as a newspaper. In this embodiment, since the angle of the second display unit 4 can be arbitrarily adjusted, when the image capturing is performed by the image capturing sensor in the second display unit 3, the second display unit 4 can be completed without looking at the second display unit 4. Since the structure of the hinge portion is improved, it is possible to make the image in the second display portion 4 of the mobile phone shown in FIG. 14 coincide with the direction of the display portion 3 and the second display portion 4 when the image is captured. The first display with image capture sensor

Therefore, the user can arbitrarily invert or rotate the display image of the display unit 4 as needed, which is not only convenient for the user, but also provides an image that is easy for others to see. Also. In addition, the image is captured by the image in the first display unit 3: the captured image is instantly displayed on the second display unit 4, and the image may be stored in the memory material. . When it is stored in the memory ^ 2^', the saved image can be read out sequentially as a still picture: the simulated animation is displayed in a continuous manner. At this time, by deleting the G 'input motion detection processing, the amount of memory required for storage can be reduced. Also, § is based on static painting, so no action time information is required to maintain the continuity of the shadow 92989.doc 17 1277937 and compress the image. (Fourth Embodiment) 彳ti« takes a video image of the image and performs color correction processing. The image enlargement device of the fourth embodiment. The block configuration in this case is the same as that of Fig. 6. The mobile phone is built in, for example, a mobile phone. Fig. 15 is a flowchart showing an example of the differential detection process performed by the LCDC 42 in the fourth embodiment. This processing is performed, for example, when the power of the mobile phone is turned on. First, the color data is a known color template as an imaging target, and image capturing is performed by the image capturing sensor in the first display unit 3 (step S31). In the color template, numerical values, characters, or bar codes are recorded as color data. Next, the color data contained in the captured image obtained by the image capture is automatically recognized, and the color data is acquired (step S32). Again, it is judged whether or not all the color templates required for the color correction are captured (step S33). If not, the process of step S31 and subsequent steps is repeated. If YES, the difference between the color data of the captured image obtained by the image capture and the color data of the obtained color template is calculated and stored in the memory or the like ( Step S34). By the above processing, it is possible to detect the deviation (difference) between the color data of the color template and the color data after the color template is taken. Fig. 16 is a flow chart showing an example of color correction display processing performed by the LCDC 42 in the fourth embodiment. First, an image pickup object is captured by the image capturing sensor in the first display unit 3 (step S41). Next, the camera shadow 92989.doc -18-1277937 is stored in the sub-picture frame memory 56 (step S42). Next, the difference data held by the processing of Fig. 15 is selected as the color L positive S (step S43). Next, the video image data is read from the sub-screen frame memory %, and correction processing is performed (step S44). Next, the enlarged image of the captured image data after the correction processing is enlarged in accordance with the magnification of 预先 beforehand is stored in the mother-side frame memory 57 (step S45). Then, the enlarged image data is read out on the horizontal line, and displayed on the second display unit 4 (step S46). Next, it is determined whether or not the imaging of the object to be imaged is completed. If the answer is no, the process returns to step S41. Then the process ends. As described above, in the fourth embodiment, since the color correction of the image of the image pickup sensor is performed, it is possible to obtain a captured image having excellent image quality. (Fifth Embodiment) In the fifth embodiment, a color template is prepared, and a color template is incorporated in the image magnifying device. Fig. 17 is a cross-sectional view showing an example of a cross-sectional structure of an image magnifying device including a color template. The image enlargement device of FIG. 17 includes a color filter substrate 73 disposed on the glass substrate 71 on which the display element or the image pickup sensor is formed, with the liquid crystal layer 72 interposed therebetween, and a backlight device 74 disposed on the backlight device 74. The back side of the color filter substrate 73. The color illuminator substrate 73 contains RGB 3-color filters that are alternately arranged. A display element or an image pickup sensor is formed on the inner side of the glass substrate 71. The image capturing sensor is formed up to the end (four) of the glass substrate 71, but the display element is not formed near the end of the glass substrate 71. Glass substrate 92989.doc -19- 1277937 A β/L light reflecting portion 75 is provided near the end portion of the 71. The B/L light reflecting portion 75 reflects the light from the backlight unit 63 and introduces an image capturing sensor. Since the color characteristics of the color filter substrate 73 are known in advance, the light reflected from the sensitized Β/L light reflecting portion 75 can be imaged, and the difference data can be calculated in the same order as in Fig. 15. Color correction can be performed in the order of Figure 16 using the calculated difference data.

In this case, in the case of a black-and-white image (especially text information) of a non-color image, it is possible to shoot even when the object to be imaged is irradiated with infrared rays instead of visible light. Infrared filaments, unlike visible light, do not cause glare, nor do they cause chemical deterioration of the subject. For example, when the LED is provided, the visible light and the infrared ray can be easily irradiated from the ith display unit 3, and the structure of the backlight device can be simplified. (Other embodiments) ^ In the above embodiments, when image manipulation is performed, Considering the reflection characteristics of the damage of the 9298.doc -20-1277937, it is preferable to design the third display unit 3 〆p like the input ^ 62 degree. a. In the case of an image-capturing object with a high reflectance (the image is in the 34-inch state or the maximum-order tone is greater than a certain area), the imaging sampling time is shortened for optimal display. On the other hand, for the image displayed on the second display unit 4 or the video display unit 61, the display magnification is set by an operation button or a knob. In the simple setting of the display magnification, the magnification of the specific number is set corresponding to the number of pixels of the first display unit 3 or the video input unit ,, so that the display can be clearly displayed. Further, it is also possible to perform image filtering processing by imaging an object to be image-captured. For example, when text is read, the text can be easily read by performing binary processing on the image. μ Further, it is possible to add a function by sampling the size of the text, for example, to determine the sub-correction reading error point, or to read the image by text, and then replace it with a font for display. An example of the method of using the image magnifying device in each of the above embodiments will be described. When an elderly person or a visually impaired person reads a small character on a paper surface, the image capturing sensor 33 picks up the page portion of the paper surface, and the captured image is enlarged and displayed on the image display portion 61. It is better to print a certain information and so on, and then zoom in and display it. Compared with repeated display of image capture and capture image, the display image is less blurred, so it is easier to buy and eyes. Will not fatigue. In addition, the number of image captures can be reduced, and power consumption can be reduced. When reading, the image of one page of the paper is captured, and the layout of the captured image can be displayed in a user-friendly manner. For example, in the case of the image capture of the two pages after the development of the book 92929.doc -21 - 1277937 ', the image of the single page is cut after the image is captured, in response to the user's ability to recognize the text (mainly Is the eyesight), set the magnification of the image. Thereby, the image can be captured in an optimum size for each user. The image magnifying device of the present embodiment can be built not only in the mobile phone 7, but also in a PC and a scanner connected to the PC. When the image enlargement device is constituted by the pc& scanner, it is not necessary to separately prepare a hard body, but the maneuverability or operability may be lowered. This is because you have to use a PC keyboard or mouse when you are performing a selection operation, etc., are you not used to it? For users of 〇 operations, it is not necessarily easy to use. However, most of the operations can be automated if only the zoom-in of the captured image is made special, so that even users who are not used to the Pc operation can easily use it. According to the present embodiment, since the captured image can be displayed immediately, the information of the electronic display board or the moving picture or the like is changed at any time, and the display is enlarged without any omission. Moreover, even when the user desires to maintain image information for a certain moment, it is easy to hold any image. In this case, it is only necessary to store the images for a moment and a moment in the frame memory. Since the memory capacity is limited, when the image is repeatedly captured, the memory capacity can be reduced by sampling at intervals of about 1 second. Also, if you want to perform a quiet display, you can stop the new image capture and read the image data in the frame memory as soon as you capture the image data to the frame memory. 92989.doc -22- 1277937 INDUSTRIAL APPLICABILITY According to the present invention, since the image captured by the first display unit is enlarged and displayed on the first and second sides, the same method as that of the magnifying glass can be used. It is especially convenient for people with visual impairments. According to the present invention, since the image captured by the enlarged image input portion is displayed on the image enlargement portion, the fine text can be easily enlarged and displayed.
