Description of the Invention: [Technical Field] The present invention relates to an image processing method and a portable electronic device using the same, and more particularly to an image processing method for adjusting an image according to a sensing distance And a portable electronic device using the same. [Prior Art] In recent years, in many briefing occasions, portable electronic devices are often used for briefing. In general, briefings need to focus on grooming in order to listen to the briefer's impression of the briefer. However, it is very inconvenient to carry an auxiliary tool such as a mirror with a mirror. Even if the portable mirror is carried, the mirror of the portable mirror is too small to be able to view the overall face and appearance, which makes it difficult for the briefing person to organize the appearance. If only the imager lens of the portable electronic device is used to shoot the presenter himself, the image captured by the image lens tends to be quite different from the image seen on the mirror. SUMMARY OF THE INVENTION The present invention relates to an image processing method and a portable electronic device using the same, which is an image processing method for adjusting an image according to a sensing distance and a portable electronic device using the same. According to an aspect of the present invention, an image processing method is provided, comprising the following steps. One image sensing device senses one of the sensing objects, and the image capturing device is disposed on a display side. The sensing object is at a distance from one of the displays. The sensing image is adjusted according to the sensing image and the distance as a display image. The display image is displayed on the display. According to another aspect of the present invention, a portable electronic device is provided, including: a display, an image capture device, a distance sensor, and an image processing module. . The image capture device is disposed on the upper side of the display to capture one of the sensing objects to sense the image. The distance sensor senses the distance of the sensor from one of the displays. The image processing module adjusts the sensing image as a display image according to the sensing image and the distance, and displays the displayed image on the display. In order to better understand the above and other aspects of the present invention, the following detailed description of the preferred embodiments and the accompanying drawings will be described in detail as follows: 实施 Embodiments Please refer to FIG. 1A for the first embodiment. A cross-sectional view of a portable electronic device 100 in accordance with a first embodiment of the present invention is shown.

As shown in FIG. 1A, in the embodiment, the image capturing device 102 is disposed on the upper side of the display 101 to capture one of the sensing objects 105 to sense the image G1. The image capturing device 102 is, for example, a wide-angle photographic lens that senses a viewing angle of zero. The distance sensor 103 senses a distance between the sensor 105 and the display 101. The distance sensor 103 includes a transmitter 103a and a receiver 103b.

TW6373PA ' J 距離感測器103係例如為紅外線距離感測器。影像處理模 組104係依據感測影像G1及距離調整感測影像G1為一顯 示影像G2，並於顯示器101顯示顯示影像G2。影像處理 模組104係例如設置於可攜式電子裝置100之主機内。可 攜式電子裝置100例如為平板電腦、智慧型手機及筆記型 電腦。可攜式電子裝置100還包括一陀螺儀106，用以感 測顯示器101之一傾斜角度。影像處理模組104更依據傾 斜角度調整感測影像G1為顯示影像G2。 以下更搭配一流程圖詳細說明使用本實施例中可攜 式電子裝置100之影像處理方法。請參照第2圖，其繪示 使用第一實施例中可攜式電子裝置100之影像處理方法的 流程圖。然而本發明所屬技術領域中具有通常知識者均可 瞭解本實施例之影像處理系統10 0並不侷限於此流程圖之 應用，且其步驟之執行順序亦不侷限於此流程圖。 首先於步驟S1中，係以影像擷取器102感測感測物 105之感測影像G1。其中，影像擷取器102設置於顯示器 101之上侧。於步驟S2中，利用距離感測器102感測感測 物105與顯示器101之距離D。於步驟S3中，影像處理模 組104依據感測影像G1及距離，調整感測影像G1為顯示 影像G2。於步驟S4中，顯示顯示影像G2於顯示器101。 關於步驟S3，請參照第3、4A及4B圖所示，將說明 依據感測影像G1及距離調整感測影像G1為顯示影像G2 之步驟，包含依據感測影像G1及距離，決定從感測影像 G1擷取顯示影像G2之尺寸及範圍。第3圖係繪示依照本 發明第一實施例，可攜式電子裝置100之影像擷取器102 201220250 < « 1 W03/JPA' 感測感測物105之示意圖。第4A圖係繪示依照本發明第 一實施例之感測影像G1之示意圖。第4B圖係繪示依照本 發明第一實施例之顯示影像G2之示意圖。 首先，先左右顛倒感測影像G1 (未繪示）。其中，左 右顛倒之基準軸，係例如為影像擷取器102至距離感測器 103之連線。 再者，如第3圖所示，影像擷取器102之感測視角為 0。影像擷取器102感測感測物105之感測影像G1之寬 φ 度為寬度L1。距離感測器102感測感測物105與顯示器 101之距離為距離D。因此，感測影像G1之寬度L1能表 示如下： LI = 2D tan(0/2)。 若感測物105位於顯示器101之中央時，如第4A圖所示， 感測物105將位於感測影像G1之下側附近。回到第3圖 所示，感測物105至顯示器101之距離D應與感測物之鏡 像至顯示器101之距離相同，而皆為距離D。因此，感測 ❿物之鏡像之寬度L3應為顯示器101之寬度L2之兩倍，即： L3 = 2L2 。 因此，從感測影像G1擷取之顯示影像G2之寬度，亦為寬 度L3。則顯示影像G2之寬度中心位置C2，應為感測影像 G1之寬度中心位置C1往顯示器101之下側偏移影像擷取 器102至顯示器中央之距離L4之位置。顯示影像G2之長 度中心位置C4則與感測影像G1之長度中心位置C3相同。 再根據顯示器101之長寬比，而從感測影像G1擷取如第 4B圖所示之顯示影像G2。如此所獲得之顯示影像G2，與 201220250The TW6373PA 'J distance sensor 103 is, for example, an infrared distance sensor. The image processing module 104 displays the image G2 according to the sensing image G1 and the distance adjustment sensing image G1, and displays the display image G2 on the display 101. The image processing module 104 is disposed, for example, in a host of the portable electronic device 100. The portable electronic device 100 is, for example, a tablet computer, a smart phone, and a notebook computer. The portable electronic device 100 further includes a gyroscope 106 for sensing an angle of inclination of the display 101. The image processing module 104 further adjusts the sensing image G1 to the display image G2 according to the tilt angle. The image processing method of the portable electronic device 100 in this embodiment is described in detail below with reference to a flowchart. Referring to FIG. 2, a flow chart of an image processing method using the portable electronic device 100 in the first embodiment is shown. However, those skilled in the art to which the present invention pertains can understand that the image processing system 10 of the present embodiment is not limited to the application of the flowchart, and the order of execution of the steps is not limited to this flowchart. First, in step S1, the image capturing device 102 senses the sensing image G1 of the sensing object 105. The image capturing device 102 is disposed on the upper side of the display 101. In step S2, the distance sensor D senses the distance D between the sensor 105 and the display 101. In step S3, the image processing module 104 adjusts the sensing image G1 to the display image G2 according to the sensing image G1 and the distance. In step S4, the display image G2 is displayed on the display 101. With regard to step S3, please refer to steps 3, 4A and 4B, and the steps of adjusting the sensing image G1 and the distance adjustment sensing image G1 as the display image G2 will be described, including determining the sensing from the sensing image G1 and the distance. The image G1 captures the size and range of the display image G2. 3 is a schematic diagram of the image sensor 102 201220250 < 1 W03/JPA' sensing sensor 105 of the portable electronic device 100 according to the first embodiment of the present invention. Fig. 4A is a schematic view showing a sensing image G1 according to the first embodiment of the present invention. Fig. 4B is a schematic view showing a display image G2 according to the first embodiment of the present invention. First, first reverse the sensing image G1 (not shown). The reference axis, which is inverted from left to right, is, for example, a line connecting the image picker 102 to the distance sensor 103. Furthermore, as shown in FIG. 3, the image capturing device 102 has a sensing angle of view of zero. The image capturing device 102 senses that the width φ of the sensing image G1 of the sensing object 105 is the width L1. The distance sensor 102 senses that the distance between the sensor 105 and the display 101 is the distance D. Therefore, the width L1 of the sensing image G1 can be expressed as follows: LI = 2D tan (0/2). If the sensing object 105 is located at the center of the display 101, as shown in FIG. 4A, the sensing object 105 will be located near the lower side of the sensing image G1. Returning to Figure 3, the distance D from the sensor 105 to the display 101 should be the same as the distance from the mirror image of the sensing object to the display 101, and both are distances D. Therefore, the width L3 of the mirror image of the sensing object should be twice the width L2 of the display 101, that is, L3 = 2L2. Therefore, the width of the display image G2 captured from the sensing image G1 is also the width L3. Then, the width center position C2 of the image G2 is displayed, and the width center position C1 of the sensing image G1 is shifted to the lower side of the display 101 by the distance L4 from the image capturing device 102 to the center of the display. The length center position C4 of the display image G2 is the same as the length center position C3 of the sensing image G1. Further, according to the aspect ratio of the display 101, the display image G2 as shown in Fig. 4B is extracted from the sensing image G1. The display image G2 thus obtained, and 201220250

In addition, the sense image G1 can be enlarged or reduced, and then the display screen can be captured. Further, for example, the tilt angle of the display 1〇1 is sensed by the gyro 106, and the sense image G1 is trapezoidally corrected according to the tilt angle. Second Embodiment Referring to Figure 5, there is shown a cross-sectional view of a portable electronic device 200 in accordance with a second embodiment of the present invention. The portable electronic device 200 includes a display 201, an image capture device 2, a distance sensor 2〇3, and an image processing module 2〇4. The distance sensor 2〇3 is another image capturing device disposed on the lower side of the display 2〇1. The display 201 and the image processing module 2〇4 are similar to the display ι〇1 and the image processing module 1〇4 of the first embodiment, and are not described herein again. The distance sensor 203 is the same as the image capturing device 202, for example, and is a wide-angle photographic lens that senses a viewing angle of zero. In other embodiments, different photographic lenses having different sensing angles or other parameters may also be used. For the convenience of explanation, the wide-angle photographic lens with the sensing angle of view is taken as an example. The present invention is not limited to this. As shown in FIG. 6 , a schematic diagram of the image capturing device 202 sensing the sensing image G1 of the sensing object 2〇5 is illustrated. As shown in FIG. 6 , a schematic diagram of the sensing sensor 203 sensing another sensing image G3 of the sensing object 205 is illustrated. Returning to Figure 5, the image processing module 204 receives the sensed image G1 and the other sensed image G3 and looks for a similar pattern in the two. In the present embodiment, if the sensor 205 is a human face, the features on the face of the person can be found as a similar pattern, such as a nose. Therefore, a similar pattern can be obtained to the image picker 2〇2 201220250 • * 1 The connection between the W03/JPA- and the plane of the display 201 is an angle of 0 1, and the similar pattern is connected to the distance sensor 203. The angle between the planes of the display 201 is an angle 02. The distance between the image capturing device 202 and the distance sensor 203 is a distance L5. The distance between the sensing object 205 and the display 201 is a distance D. The distance D can be expressed as follows: D = L5 tan 0 1 tan 02 / (tan 0 1 + tan0 2) Referring to Fig. 6C, there is shown a schematic diagram of the display image G2 according to the second embodiment of the present invention. Therefore, the image processing module 204 can determine, for example, the sensing image G1 or the other sensing image G3 according to the sensing image G1 or another sensing image G3 and the distance D by using the image processing method of the first embodiment. The size and range of the display image G2 as shown in Fig. 6 are taken. If the size and range of the display image G2 are extracted from the other sensing image G3 according to the other sensing image G3 and the distance, the upper side and the lower side of the image processing method of the first embodiment are used. Decide to display the range of image G2. Please refer to FIG. 6D, which is a schematic diagram of the combined image G4 according to the second embodiment of the present invention. In other implementations, the image processing module 204 can combine the sensing image G1 and the other sensing image G3 into the combined image G4, and according to the combined image G4 and the distance D, determine to extract from the combined image G4 as shown in FIG. 6C. The size and range of the display image G2 shown. Wherein, if the sensing object 205 is placed in the center of the display 201, the center of the display image G2 is the same as the center of the combined image G4. Since the portable electronic device provides an image capturing device and a distance sensor, the sensing object image that is biased to one side of the sensing image can be captured from the sensing shadow 201220250 TW6373PA '* image to the center of the image. , in turn, provides a picture close to the image. The user can directly use the portable electronic device to produce a mirror-like image to achieve the effect of illuminating the mirror. In addition, you can zoom in or out on the sensed image before capturing the display surface. Therefore, when there is no mirror at hand or the mirror of the portable mirror is too small, the portable electronic device allows the user to easily observe the appearance of the body. In addition, since another image capture device is provided, the sensed image can be enlarged to be combined with the image, so that the range of the captured image is more flexible. In addition, since the combined image is composed of a plurality of sensing images obtained by sensing the sensing objects from different angles, it is possible to avoid the occurrence of dead angle of the image and to avoid the occurrence of trapezoidal deformation of the sensing image. In summary, although the invention has been disclosed above by way of example, it is not intended to limit the invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
