Description

Electronic equipment

The present invention relates to an electronic device, and more particularly to an electronic device capable of capturing objects at close and long distances.

With the development of optical imaging technology, camera modules are widely used in various portable imaging devices such as mobile phones and notebook computers. For details, see Capturing images with digital still cameras, Micro, IEEE Volume: 18, issue: 6, Nov.-Dec.1998 Page(s): 14-19.

In order to meet the demand for miniaturization of portable electronic devices, a camera module disposed in a portable electronic device is generally a fixed-focus camera module having a simple structure and no actuator. The above-mentioned fixed-focus camera module is usually used for shooting distant objects, and the object is designed to be larger than 60 cm from the lens. Images taken at close distances such as objects 10 to 20 cm away from the lens under natural light conditions are 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 performs images of three colors of light. Color mixing 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 generated by the red light is different, and when the images formed by the red light, the yellow light, and the blue light are mixed, the image sensor cannot form a clear image.

The 2D motion bar code is usually small, and the image obtained when shooting from a long distance is small and cannot be recognized. Therefore, the identification of the two-dimensional action bar code is usually performed at a relatively close distance, and the electronic device having the fixed focus camera module is used to perform information information that cannot accurately recognize the two-dimensional action bar code.

In view of this, it is necessary to provide an electronic device capable of obtaining clear images for both close-range objects and distant objects.

A portable electronic device will now be described 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. For transmitting light having a wavelength in the range of 400 nm to 500 nm, the transparent sheet is movably disposed on the casing to selectively block or not block the camera module, when the transparent sheet is blocked In 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 long-distance imaging when the transparent film does not block the camera module.

Compared with the prior art, the electronic device provided by the technical solution includes a fixed focus camera module and can set a short-wavelength transparent film by setting a relative position of the transparent film and the camera module, when the transparent film is not blocked. When the image side of the camera module is used, 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.

The first fixing member 131 and the first fixing member 131 are respectively A stopper 133, a second fixing member 132 and a second stopper 134 enclose a receiving space 135. The opening 1113 is exposed from the accommodating space 135. In this embodiment, the opening 1113 is disposed adjacent to the first stopper 133.

The first fixing member 131 and the first fixing member 132 are used for cooperating to receive the light-transmitting 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 first fixing rod 1311 vertically fixes the back surface 1113. The first receiving rod 1312 is parallel to the back surface 1113. The first receiving rod 1312, the first fixing rod 1311 and the housing 110 form a first sliding slot (not shown). The second fixing member 132 includes a second fixing rod 1321 and a second receiving rod 1322 that are connected to each other. The second fixing rod 1321 vertically fixes the back surface 1113, the second receiving rod 1322 is parallel to the back surface 1113, and the second receiving rod 1322 and the second fixing rod The 1321 and the housing 110 form a second chute 137. The first chute is opposite to the opening direction of the second chute 137. Preferably, the heights of the first fixing rod 1311 and the second receiving rod 1321 are equal to the thickness of the transparent sheet 140.

The first stopper 133 and the second stopper 134 are used to define a position at which the transparent sheet 140 moves along the first sliding slot and the second sliding slot 137. In this 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 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 sliding out of the first sliding slot and the second sliding slot 137.

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 light-transmitting sheet 140 is a blue rectangular sheet-like structure, and the light-transmitting sheet 140 may be made of a light-transmitting material such as glass or plastic. The color of the light-transmitting sheet 140 corresponds to a wavelength range of 400 to 500 nm. . The length of the transparent sheet 140 is equal to the distance between the first fixing rod 1311 and the second fixing rod 1321, and the width of the transparent 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 the transparent sheet 140 can be moved along the first sliding slot and the second sliding slot 137 by applying an external force.

Referring to FIG. 3 and FIG. 4, the electronic device 100 is used for close-range photography.

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 on the image sensor 122, so that light of other wavelength ranges cannot be imaged through the optical element 121. Light with different wavelengths, through the same The mass has a different refractive index. 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 imaging area of the light having a larger wavelength is larger, and the imaging area of the light having a smaller wavelength is smaller. Therefore, only the light having a wavelength range of 400 to 500 nm has a smaller imaging area in the image formed by the image sensor 122, and the obtained image has higher definition. Since the recognition process of the two-dimensional action bar code only needs to recognize its shape without identifying its color. When the electronic device 100 is used to recognize the two-dimensional action bar code in close proximity, the bar code information can be accurately identified.
