It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the utility model, and are not intended to limit the scope of the utility model in any way.

Summary of the utility model

The inventor of the present invention has found that a dictionary pen is generally limited to "I" shaped travel switches during operation. As shown in fig. 1, on the one hand, the viewing angle of the scanning camera cannot be too large in order to place the "i" shaped travel switch. On the other hand, the existing camera and the light supplement lamp are separately arranged, so that the pen point is large in size, the corresponding travel switch is too large, and the scanned characters are difficult to ensure to be in the middle of the image. In practice, this configuration requires the elimination of the area where the travel switch enters the camera (e.g., it may require 1/5 or more areas of a camera to be eliminated). This design also limits the viewing angle of the camera to not be too large to ensure that the field of view is within two feet of the travel switch. Meanwhile, in order to effectively capture images, the distance between two feet of the travel switch is required to be appropriate so as to prevent the situations that the images cannot be captured when the size is too small and the images cannot be correctly positioned when the size is too large. In addition, the inventor also finds that the light path design of the fill-in light is not only difficult, but also the light-emitting angle is difficult to arrange, and once the control is not accurate enough (for example, too large or too small), the image quality is unstable.

Based on above-mentioned problem, the inventor finds that through design light filling lamp and the camera that integrates and make the light filling lamp distribute around the camera, can effectively reduce the design degree of difficulty of overall structure and light path, and be difficult for receiving the restriction of nib size, be favorable to improving the image quality who gathers and ensure the stability of product.

According to an embodiment of the present invention, a portable electronic device is provided. Moreover, any number of elements in the drawings are by way of example and not by way of limitation, and any nomenclature is used solely for differentiation and not by way of limitation.

Further, with reference to fig. 5, other components that may be included in the aforementioned image capturing mechanism will be described. Fig. 5 schematically shows a cross-sectional structure diagram of an image acquisition mechanism according to an embodiment of the present invention. As shown in fig. 5, in some embodiments, the image capturing mechanism 201 may further include a light-correcting device 2013, which may be disposed in front of the fill-in light and used for correcting the light of the fill-in light.

In some embodiments, the light ray correction device 2013 may include a diffusion sheet or a concave lens, which may weaken noise that may exist during image acquisition, so as to effectively avoid the influence of the noise on the image, thereby improving the quality of the acquired image.

In some implementations, the present invention preferably employs a fresnel lens as the light ray correction device 2013. The Fresnel lens can also be called as a screw lens, one surface of the lens surface is a smooth surface, the other surface is inscribed with concentric circles from small to large, and the textures are designed according to the requirements of light interference, relative sensitivity, receiving angle and the like, so that the light can be better corrected.
