[0002] In related technologies, a camera device on a terminal device such as a mobile phone or a tablet computer is configured with a macro photography function. When the camera device performs the macro photography function, the camera device is close to the photographed object, which blocks the ambient light irradiated on the surface of the photographed object, thereby reducing the light energy received by the camera device and affecting the image quality. Therefore, it is necessary to provide light compensation to improve the image quality.

When the distance to the photographed object is far, the light compensation illumination is relatively uniform and the effect is good.

[0046] The example embodiments will be described in detail herein with reference to the attached drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The following description of example embodiments is not representative of all embodiments consistent with the present disclosure. Rather, it is merely an example of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0047] In related art, the camera on a terminal device such as a mobile phone or a tablet computer is configured with a macro photography function. When the camera performs the macro photography function, the camera is close to the photographed object, which blocks the ambient light on the surface of the photographed object, thereby reducing the light energy received by the camera and affecting the image quality. Therefore, light supplement is needed to improve the image quality.
[0048] A conventional light supplement method is to configure a light supplement lamp near the camera module. When the distance between the camera and the photographed object is far, the light supplement is relatively uniform, and the image quality is good. However, when the camera performs the macro photography function, for example, when the distance between the photographed object and the camera is less than 1 cm, because of the physical distance between the camera module and the light supplement lamp and the non-uniform light distribution of the light supplement lamp itself, the light intensity in the field of view of the camera module is non-uniform, which leads to non-uniform image quality. For example, the light distribution of the light supplement lamp is usually brighter in the center and darker at the edges. In the field of view of the camera module, the image on the side close to the light supplement lamp is brighter, and the image on the side far from the light supplement lamp is darker, and the image quality in the dark area is poor.
[0049] To solve the above problems, a light compensation module is usually arranged symmetrically on both sides or around the camera module to solve the problem of non-uniform illumination in the field of view of the camera module. However, this solution has the following disadvantages: (1) high power consumption, because the light compensation module needs to be designed symmetrically, at least two LEDs (light emitting diodes) are needed, and in addition to the light in the region coinciding with the central field of view of the camera module, the light around the edges is still wasted; that is, the light emitting angle of the light compensation module is much larger than the field of view of the camera module, and part of the light is wasted; (2) the uniformity of the illumination in the field of view of the camera module is still insufficient, although the design is symmetrical, unless there are enough LEDs, the dark area in the field of view of the camera module can be significantly improved, and when the number of LEDs is small, such as less than 3, the illumination distribution in the field of view of the camera module is still relatively dark, and the bright area may cause overexposure; (3) large size, and appearance is limited.
[0050] Figures 1-5 is a structural schematic diagram of a camera device 100 according to an exemplary embodiment. Wherein, Figure 2 is a top view of Figure 1 , Figure 3 is a sectional view along the section line DD, Figure 2 Figure 4 is a sectional view along the section line AA, Figure 3 Figure 5 is a sectional view along the section line BB. As shown in Figure 4 , the camera device 100 comprises a camera module 11, a light compensation module 12, a first support 13, a first housing 14 and a glass cover plate 15. Figures 1-5 As shown in
[0051] , the first housing 14 covers the first support 13, and the first housing 14 and the first support 13 form a containing space, and the camera module 11 and the light compensation module 12 are located in the containing space. The first housing 14 is provided with an opening, and the glass cover plate 15 is embedded in the opening. The glass cover plate 15 is transparent and can allow visible light and ultraviolet light to pass through. Figures 1-2 In an optional embodiment, as shown in
[0052] , the camera device 100 further comprises a flexible circuit board 16 and a second printed circuit board 17. One end of the flexible circuit board 16 is respectively electrically connected with the camera module 11 and the light compensation module 12, and the other end of the flexible circuit board 16 is further electrically connected with the second printed circuit board 17. The camera module 11 and the light compensation module 12 are electrically connected with the second printed circuit board 17 through the flexible circuit board 16. Figures 1-2 As shown in
[0053] , the camera device 100 further comprises a flexible circuit board 16 and a second printed circuit board 17. One end of the flexible circuit board 16 is respectively electrically connected with the camera module 11 and the light compensation module 12, and the other end of the flexible circuit board 16 is further electrically connected with the second printed circuit board 17. The camera module 11 and the light compensation module 12 are electrically connected with the second printed circuit board 17 through the flexible circuit board 16. Figure 3 As shown, the first light beam L1 emitted by the supplementary lighting module 12 exits through the aforementioned opening, or in other words, the first light beam L1 emitted by the supplementary lighting module 12 exits through the glass cover plate 15. A second light beam L2 from outside the imaging device 100 enters the camera module 11 through the aforementioned opening for imaging, or in other words, the second light beam L2 from outside the imaging device 100 enters the camera module 11 through the glass cover plate 15 for imaging. The optical path of the second light beam L2 is located within the optical path of the first light beam L1. The field of view β of the imaging device 100 is located within the supplementary lighting emission angle α of the imaging device 100. Here, the supplementary lighting emission angle α is the scattering angle of the first light beam L1. That is, the optical path of the light beam incident on the camera module 11 for imaging is located within the optical path of the light beam emitted by the supplementary lighting module 12 for supplementary lighting; that is, the field of view of the imaging device 100 is located within the supplementary lighting optical path of the supplementary lighting module 12. This allows for uniform illumination within the field of view of the camera device 100, thereby resulting in more uniform image quality captured by the camera device.
[0054] In an optional embodiment, the illumination angle α of the imaging device 100 can be substantially the same as the field of view β of the imaging device 100. This eliminates the need for only one illumination module 12, avoiding the need for symmetrical or multiple illumination modules 12, thus improving illumination efficiency and reducing power consumption. Since only one illumination module 12 is used, the dark areas in illumination caused by multiple illumination modules 12 are eliminated, improving the uniformity of illumination. Furthermore, the size of the imaging device can be reduced, lessening the limitations on its appearance.
[0055] In an optional embodiment, the supplementary light emission angle α of the camera device 100 may be slightly larger than the field of view angle β of the camera device 100.
[0056] In an optional embodiment, such as Figure 3 As shown, the camera device 100 also includes a second bracket 31, and the first bracket 13 includes a base frame 135. The base frame 135 is opposite to the first housing 14. The second bracket 31 is fixed to the surface of the first housing 14 facing the base frame 135, and the second bracket 31 is used to support the glass cover plate 15.
[0057] In an optional embodiment, such as Figure 4 As shown, the camera device 100 also includes a first reflector 41, a beam splitter 42, and a second reflector 43. The first reflector 41, the beam splitter 42, and the second reflector 43 are respectively located on the first support 13. The beam splitter 42 partially transmits and partially reflects.
[0058] like Figure 4As shown, the light beam emitted by the light supplement module 12 is reflected by the first mirror 41, the light splitting element 42 and the second mirror 43 in sequence to form the first light beam L1, and the first light beam L1 is emitted through the glass cover plate 15 in the opening. The second light beam L2 from outside the camera 100 is incident through the opening, reflected by the second mirror 43 to form the third light beam L3, transmitted by the light splitting element 42 to form the fourth light beam L4, and incident to the camera module 11. The camera module 11 can image after receiving the fourth light beam L4. On the side of the light splitting element 42 away from the camera module 11, the light path of the light beam incident to the camera module 11 is in the light path of the light beam emitted by the light supplement module 12. In this way, the light supplement illumination in the field of view of the camera 100 can be uniform, and the image quality of the camera can be more uniform.
[0059] As shown in Figure 4 The first support 13 further includes a first side wall 131, a second side wall 132, a third side wall 133 and a fourth side wall 134. The first side wall 131 is adjacent to the second side wall 132 and the fourth side wall 134, and opposite to the third side wall 133. The second side wall 132 is opposite to the fourth side wall 134. The first side wall 131, the second side wall 132, the third side wall 133 and the fourth side wall 134 are located between the bottom frame 135 and the first housing 14.
[0060] As shown in Figure 4 The camera module 11 and the light supplement module 12 are fixed on the first side wall 131. The light emitting surface of the light supplement module 12 faces the third side wall 133, and the light receiving surface of the camera module 11 faces the third side wall 133. The light emitting surface of the light supplement module 12 is the light emitting surface of the light emitting chip in the light supplement module 11, and the light receiving surface of the camera module 11 is the light receiving surface of the image sensor in the camera module 11.
[0061] As shown in Figure 4 The projection of the camera module 11 on the first side wall 131 is located in the projection of the light splitting element 42 on the first side wall 131. In this way, it can be ensured that the light passing through the light splitting element 42 can be incident to the camera module 11.
[0062] As shown in Figure 4 The first mirror 41 is fixed on the second side wall 132. The first mirror 41 includes a first reflecting surface Fr1. The first reflecting surface Fr1 faces the light emitting surface of the light supplement module 12, and is inclined with respect to the light emitting surface of the light supplement module 12. For example, the angle between the first reflecting surface Fr1 and the light emitting surface of the light supplement module 12 is 45 degrees.
[0063] As shown in Figure 4As shown, the light splitting element 42 is fixed on the fourth side wall 134, the light splitting element 42 comprises a first surface F1 and a second surface F2, the first surface F1 and the second surface F2 are opposite, the first surface F1 is opposite to the first reflecting surface Fr1, the second surface F2 is opposite to the light receiving surface of the camera module 11, and the first surface F1 and the second surface F2 are obliquely arranged relative to the fourth side wall 134. For example, the angle between the first surface F1 and the fourth side wall 134 is 45 degrees, and the angle between the second surface F2 and the fourth side wall 134 is 45 degrees.
[0064] As shown in Figure 5 , the second reflecting mirror 43 is fixed on the third side wall 133 and the bottom frame 135, the second reflecting mirror 43 comprises a second reflecting surface Fr2, the second reflecting surface Fr2 is opposite to the first surface F1, and the second reflecting surface Fr2 is obliquely arranged relative to the opening, or in other words, the second reflecting surface Fr2 is obliquely arranged relative to the glass cover plate 15.
[0065] As shown in Figure 5 , the projection of the opening on the bottom frame 135 is located within the projection of the second reflecting mirror 43 on the bottom frame 135. Or in other words, the projection of the glass cover plate 15 on the bottom frame 135 is located within the projection of the second reflecting mirror 43 on the bottom frame 135. In this way, the second reflecting mirror 43 can make full use of the light incident from the opening to be incident to the camera module 11, which is beneficial to improve the image quality.
[0066] As shown in Figure 6 , the camera device 100 further comprises a connector 61. The connector 61 is located on the second printed circuit board 17. The camera module 11 and the light supplementing module 12 can be electrically connected to other devices through the connector 61, for example, the camera module 11 and the light supplementing module 12 can be electrically connected to the control chip through the connector 61.
[0067] In an optional embodiment, as shown in Figure 7 , the camera module 11 and the light supplementing module 12 can be arranged side by side on the first side wall 131.

[0070] like Figure 8 As shown, the image sensor 111 is located on and electrically connected to the third printed circuit board 82.

The third bracket 112 is located on the side of the image sensor 111 away from the first reinforcing plate 81 and is fixed to the third printed circuit board 82, serving to support the dual-pass filter 113. The dual-pass filter 113 is located on the third bracket 112 and between the image sensor 111 and the first lens 114. The dual-pass filter 113 allows visible and ultraviolet light to pass through while blocking light of other wavelengths. The first lens 114 can be a macro lens.
[0071] In an optional embodiment, the dual-pass filter 113 may include a substrate and a filter film. The substrate has high transmittance for both visible and ultraviolet light.

A reflector 123 is located on the first printed circuit board 121, on the side of the first printed circuit board 121 away from the third printed circuit board 82, and surrounds the light-emitting chip 122. A second lens 124 is covered by the reflector 123. The reflector 123 reflects the light emitted by the light-emitting chip 122 to the second lens 124, and the second lens 124 emits the light emitted by the light-emitting chip 122 at a specified emission angle.
[0074] In an alternative embodiment, the second lens 124 may be a Fresnel lens or a lens group comprising several lenses.

In this embodiment, the first light-emitting chip 1221 and the second light-emitting chip 1222 share a common cathode. In other embodiments, the first light-emitting chip 1221 and the second light-emitting chip 1222 may also share a common positive electrode.
[0076] In an optional embodiment, the first light-emitting chip 1221 is used to emit visible light, and the second light-emitting chip 1222 is used to emit ultraviolet light.
