Description of the Invention: [Technical Field] [0001] The present invention relates to an electronic device, and more particularly to an electronic device capable of capturing objects at close and long distances. [Previous Technology] [0002] With the development of optical imaging technology, camera modules are widely used in various electronic devices such as mobile phones and notebook computers. For details, see Capturing images with digital 0 still cameras, Micro. , IEEE Volume: 18, is- sue: 6, Nov.-Dec. 1998 Page(s): 14-19. [0003] In order to meet the demand for miniaturization of portable electronic devices, a camera module provided in a portable electronic device is a fixed-focus camera module having a simple structure and no actuator. The above-mentioned fixed-focus camera module is usually used for shooting distances: 〆. When the object is designed, the object is larger than 60 cm from the lens. When the distance is close to the lens under natural light conditions, such as when the object is 1 to 2 cm away from the lens - | p; ; :;:: .: ^j ^ /' "^! ί; The captured image is not clear. Because the image sensor of the camera module senses light of a certain wavelength range when performing image sensing, usually the image sensor senses wavelengths corresponding to red, yellow, and blue light, and then the three colors of light are formed. ;^ Image is mixed to get an image. However, the wavelengths of red light, yellow light, and blue light are different. The light of three colors passes through the optical components such as lenses in the camera module, and the angle of refraction is different. When the red, yellow, and blue light images are concentrated on the image. When the detector is used, the convergence point of red light is different. When the images formed by red, yellow and blue light are mixed, the image sensor cannot form a clear image. [0004] Two-dimensional moving barcodes are usually small, using long distances. Image obtained during camera 098123963 Form number Α0101 0982040839-0 Page 3 of 21102102747 Very small, unrecognizable. Therefore, the identification of the two-dimensional action bar code is usually performed at a relatively short distance, and the electronic device having the fixed focus camera module is used to perform the information information of the two-dimensional action bar code that cannot be accurately recognized. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide an electronic device capable of obtaining clear images for both close-range objects and distant objects. [0006] A portable electronic device will be described below by way of example. An electronic device includes a housing, a camera module, and a light transmissive sheet. The camera module is received in the housing and exposed from the surface of the housing. The focus of the camera module is set at infinity. The light transmissive sheet is for transmitting light having a wavelength ranging from 400 nm to 500 nm, and the light transmissive sheet is movably disposed on the casing to selectively block or not block the camera module when When the light transmissive sheet blocks the camera module, the camera module performs close-range imaging with light having a wavelength ranging from 400 nm to 500 nm, and the camera module performs far-reaching when the transparent film does not block the camera module. Distance imaging. [0008] Compared with the prior art, the electronic device provided by the technical solution includes a fixed focus camera module and can set a relative position of the transparent film and the camera module through the setting of the short-wavelength transparent film. When the film is not blocked on the image side of the camera module, the electronic device obtains a clear image from a distant object; when the light-transmitting sheet blocks the image side of the camera module, the electronic device obtains a clear image from a relatively close object. [Embodiment] The electronic device of the present technical solution will be further described in detail below with reference to the accompanying drawings and the embodiments. 098123963 Form No. A0101 Page 4 / Total 21 Page 0992040839-0 201102747 [0010] Please refer to FIG. 1 to FIG. 3 together.

In this embodiment, The sliding structure 130 includes a first fixing member 131, a first stopping member 133, a second fixing member 132 and a second stopping member 134. The second fixing member 132 is parallel to the first fixing member 131, and the first stopping member The member 133 is parallel to the second stopper 134, and the first fixing member 131 The first fixing member 131, the first stopping member 133, the second fixing member 132 and the second stopping member 134 enclose a receiving space 135. The opening 1113 is exposed from the receiving space 135. In this embodiment, the opening 1丨j 3 is disposed close to the first stopper 133. ............................................ [0015] The first fixing member 131 and the first fixing member 13 2 are used for cooperating to receive the transparent sheet 140. The first fixing member 131 includes a first fixing rod 1311 and a first receiving rod 1312 which are connected to each other. The rod 1311 vertically fixes the back surface 1113, the first receiving rod 1312 is parallel to the back surface m3, and the first receiving rod 1312, the first fixing rod 1313 and the casing 11〇 form a first sliding groove (not shown) and the first fixing member The second fixing rod 1321 and the second receiving cup 1 322 are connected to each other. The second fixing bracket 1321 vertically fixes the back surface 111S, the second receiving rod 1322 is parallel to the back surface 1113, the second receiving rod 1322, the second fixing rod 1321 and The housing 11 is formed with a second sliding slot 137. The first sliding slot is opposite to the opening direction of the second sliding slot 137. Preferably, the first fixing rod 1311 is higher than the second receiving rod 1321. The thickness of the light-transmissive sheet 14 is equal to that of the second sliding groove 137. [0016] The first stopper 133 and the second stopper 134 are used to define a position where the light-transmitting sheet 14 is moved along the first sliding groove and the second sliding groove 137. In the embodiment, the first stopper 133 and the second stopper 134 are both a baffle fixedly connected between the first fixing member 131 and the second fixing member 132. It can be understood that the first 098123963 Form No. A0101 Page 6 / 21 pages 0992040839-0 201102747 The stopper 133 and the second stopper 134 can also be one or a plurality of protrusions as long as they can block the transparent sheet 140 from slipping out The first chute and the second chute 13 7 are sufficient. [0017] 透光 The light-transmissive sheet 140 is used for the light of the set wavelength when the near-field imaging is performed. In this embodiment, the transparent sheet 14 is a blue rectangular sheet-shaped structure. The transparent sheet 140 may be made of a light-transmitting material such as glass or plastic. The color of the transparent sheet 140 corresponds to a wavelength range of 4 〇〇 to 500 nm. The length of the light-transmissive sheet 140 is equal to the distance between the first fixing rod 131 丨 and the second fixing rod 1321. The width of the light-transmitting sheet 140 should be larger than the diameter of the opening 1113. The light-transmissive sheet 140 is accommodated in the first sliding slot and the second sliding slot 137, and can be moved to move along the first sliding slot and the second sliding slot 137 by applying an external force. [0018] Referring to FIG. 3 and FIG. 4, the electronic device 1 is used to enter the distance imaging. First, the light transmissive sheet 140 is shielded from the side of the camera module 120 by applying an external force to slide the light transmissive sheet 140, and the light transmissive sheet 140 is in the first position. After entering the phase >-, -:;: the light of the module 120 passes through the transparent sheet 140, so that the wavelength and the color of the transparent sheet 140 correspond to the first line of the wavelength range. In this embodiment, light having a wavelength in the range of 400 to 500 nm is imaged by the optical sensor 121 of the camera module 120 to the image sensor 122 so that light of other wavelength ranges cannot be imaged by the optical element 121. Light with different wavelengths has different refractive indices when passing through the same medium. Therefore, when performing close-range imaging, the same subject has different wavelength ranges in which the light converges through the optical element and the size of the area is different. Among them, the light having a larger wavelength has a larger imaging area, and the light having a smaller wavelength has a smaller imaging area. Therefore, only the light with a wavelength range of 400 to 500 nm is formed by the image detector 122. 098123963 Form No. 1010101 Page 7/Total 21 page 0982040839-0 201102747 The image has a smaller imaging area, and the obtained image has a larger image. High definition. Since the recognition of the two-dimensional action bar code, it is only necessary to recognize its shape ' without identifying its color.

When the electronic device 100 is used for remote photography, the light transmissive sheet 140 is controlled to be in the second position relative to the camera module 120 such that the light transmissive sheet 140 is not covered by the object side of the camera module 120, and the camera module 120 remains It can capture sharp objects from distant objects under natural light conditions. [0020] Referring to FIG. 5 and FIG. 6 , the electronic device 200 provided by the second embodiment of the present invention has a structure similar to that of the electronic device 100 provided by the first embodiment of the present technical solution. The back surface 2112 of the housing 21 of the electronic device 200 is provided with two phases. The parallel first & slot 211 and the second slot 212' are disposed on the surface opposite to the transparent sheet 240 and the back surface 2112. There is a first sliding rail 241 corresponding to the first sliding slot 211 and a second sliding rail 242 corresponding to the second sliding slot 212. The first sliding rail 241 is fit and received in the first sliding slot 212. The accommodating portion is received in the second sliding slot 212 so that the light transmitting sheet 240 can move along the first sliding rail 241 and the second sliding rail 242 under the action of an external force.
