detailed description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments of the present invention. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention , for those skilled in the art, other drawings can also be obtained according to these drawings without paying creative labor.

Referring to FIG. 1 , it shows a schematic structural diagram of an imaging device according to an embodiment of the present invention.

The camera device can be applied to smart phones, PDA (PersonalDigitalAssistant, handheld computer), PC (PersonalComputer, personal computer), MP3 player, e-book reader, intelligent robot, smart wearable equipment and other mobile terminals that need to use the camera device, The mobile terminal can use the camera device to realize functions such as taking pictures and identifying frontal fingerprints, and the operating system of the mobile terminal can include operating systems such as Android (Android), IOS, WindowsPhone, and Windows, which are not limited by the present invention.

In the embodiment of the present invention, the imaging device may include a camera 101, a fill light 102, and a glass cover 103 covering the camera 101 and the fill light 102. The first anti-reflection layer 104 on one side of 101.

Wherein, the camera 101 may include a front camera of a mobile terminal, the camera 101 has an end face, the end face of the camera 101 may be a side close to the glass cover 103, such as a plane corresponding to the camera hole, and the end face of the camera 101 may be circular.

The supplementary light 102 can be used to emit supplementary light in the supplementary light mode. As shown in FIG. 2 , a part of the supplementary light emitted by the supplementary light 102 can be diffusely reflected inside the glass cover 103 , and enters after multiple reflections. The camera 101 reduces the imaging quality of the camera 101, and the other part can enter through the glass cover 103, and return to the camera 101 after being reflected by the subject, so that the camera 101 collects more light for imaging, and has a better imaging effect.

It should be noted that diffuse reflection is a phenomenon in which light projected on a rough surface is reflected in all directions. When a beam of parallel incident light hits a rough surface, the surface will reflect the light in all directions, so although the incident rays are parallel to each other, the reflected light will randomly reflect in different directions due to the inconsistency of the normal direction of each point. This reflection is called "diffuse reflection".

The glass cover 103 covers the top of the camera 101 and the fill light 102, the glass cover 103 can be made of a transparent substrate, one side of the glass cover 103 is close to the camera 101 and the fill light 102, the other side of the glass cover 103 Close to the user and accessible by hand.

The first anti-reflection layer 104 is coated on the side of the glass cover 103 close to the camera 101. The first anti-reflection layer 104 can be made of materials that prevent light reflection, without adding other redundant materials or taking up more space. .

As shown in Fig. 3, the first anti-reflection layer 104 can be used to absorb the light emitted by the supplementary light 102 and reflected by the glass cover 103. Since the first anti-reflection layer 104 is coated, the light reflected by the glass cover 103 contacts the first An anti-reflection layer 104 will not reflect again, and thus will not enter the camera 101 .

By arranging the first anti-reflection layer 104, the interference of the fill light 102 to the viewfinder of the camera 101 is improved. Correspondingly, the camera 101 does not need to be arranged at a position far from the fill light 102, reducing the position design of the camera 101. limitations, making the layout of internal devices more free.

As an example, the thickness of the first anti-reflection layer 104 can be set to be small, and the thickness of the first anti-reflection layer 104 can be less than or equal to 0.02 mm, so as not to affect the thickness of the glass cover 103 .

The material of the first anti-reflection layer 104 may at least include: ink or paint, and the manner of coating the first anti-reflection layer 104 may at least include: printing or spraying.

Of course, those skilled in the art can also use the first anti-reflection layer 104 of other materials, and use other methods to coat the first anti-reflection layer 104, such as adopting a laser method to perform high temperature on the side of the glass cover plate 103 close to the camera 101. Radium engraving process to form the first anti-reflection layer 104 .

In a specific implementation, since the camera 101 needs to collect light reflected by the subject, and the area of the glass cover 103 covering the camera 101 needs to be able to transmit light, the first anti-reflection layer 104 may have a first opening area.

Wherein, since the end face of the camera 101 may be circular, the first opening area is set opposite to the camera 101, and the end face of the camera 101 and the first opening area may be concentric circles with equal diameters.

By setting the first opening area opposite to the camera 101 on the first anti-reflection layer 104, concentric with the end face of the camera 101 and having the same diameter, the first anti-reflection layer 104 is separated from the left and right sides, so that the camera can capture both The light in the environment avoids collecting the light emitted by the supplementary light 102 and reflected by the glass cover 103, and eliminates the need to use software to correct the imaging information after the imaging of the camera 101, so that the imaging is more realistic. The image quality is also improved.

In a preferred embodiment of the present invention, the camera 101 has a light entrance angle, and light can only be captured by the camera 101 if it enters from the light entrance angle. Entering the camera 101, the length of the first anti-reflection layer 104 on both sides of the first opening area can be greater than or equal to the length of the reflection area corresponding to the light incident angle of the camera 101, so that the first anti-reflection layer 104 can fully absorb the fill light Among the light emitted and reflected by the glass cover, the light that can enter the camera.

As an example, the reflection area corresponding to the light entrance angle is located on the side of the glass cover 103 close to the camera 101, and the light reflected by the reflection area can enter the light entrance angle after one reflection on the other side of the glass cover 103, as shown in Figure 4 As shown, the two sides of the incident light angle of the camera 101 are respectively a and b, and a and b are taken as incident rays, and a perpendicular line is drawn perpendicular to the glass cover plate 103, then the reflected rays of a and b can be obtained, and then The reflection area corresponding to the light angle may include the area between the reflection line of a and a and the intersection point of the glass cover 103 near the camera 101, and the reflection line of b and b and the intersection of the glass cover 103 near the camera 101.
