Background

At present, the existing dual-light fusion equipment is generally composed of two independent camera modules, and the two camera modules comprise an ordinary RGB camera and an infrared camera module. The two camera modules respectively shoot and output images to the image processing chip, and the images are analyzed by the image processing chip and then fused through an algorithm to obtain a double-light fusion image. However, after the two camera modules output images, the target image can be obtained only after the images are analyzed and fused by the image processing chip, and the imaging time is long, which may cause a certain delay in actual image display and shooting. Two camera modules usually need to be matched with two different image sensors, so that the cost of the dual-light fusion equipment is higher, extra calibration is needed in the production process, and the precision requirement on the production equipment is extremely high. Meanwhile, the resolution of the infrared camera is generally smaller than that of the RGB camera, and loss of image edge pixels can be caused after algorithm fusion, so that the resolution of a target image is lower than that of the infrared camera, and image quality is low.

Please refer to fig. 1, which is a schematic diagram of an internal structure of a dual optical fusion imaging apparatus according to an embodiment of the present application. The dual-light fusion imaging device 1 is applied to electronic equipment with a camera function, and the electronic equipment includes but is not limited to a smart phone, a tablet computer, a notebook computer, a smart watch, a smart door lock, or the like.

The bifocal fusion imaging apparatus 1 includes a filter assembly 10 and a camera 20. Specifically, the camera 20 includes a lens 21. In the present embodiment, the camera 20 includes at least two lenses 21. The thickness, curvature, optical parameters of the lenses 21, the gap between the lenses 21, and the number of the lenses 21 may be set according to actual requirements, which is not limited herein.

The filter assembly 10 includes a rotating assembly 13, a first filter 11, and a second filter 12.

The initial light passes through the first filter 11 to form a first incident light, and the initial light passes through the second filter 12 to form a second incident light. The wavelength of the first incident light is different from the wavelength of the second incident light. In the present embodiment, one of the first incident light and the second incident light is visible light, and the other of the first incident light and the second incident light is infrared light. That is, the first incident light is visible light and the second incident light is infrared light, or the first incident light is infrared light and the second incident light is visible light. The following description will be given in detail by taking the first incident light as visible light and the second incident light as infrared light as an example. It is understood that the first optical filter 11 is capable of transmitting light having a wavelength of 380 to 780nm, i.e., visible light; the second filter 12 is capable of transmitting light having a wavelength of 930-950nm, i.e., infrared light. The initial light is natural light, only visible light is retained after the initial light passes through the first optical filter 11, and only infrared light is retained after the initial light passes through the second optical filter 12.

The rotating component 13 is used for alternately inputting the first incident light and the second incident light to the lens 21, and the bifocalization imaging device 1 exposes only the first incident light or the second incident light at a time. It can be understood that, when the rotating component 13 makes the first incident light incident to the lens 21, the bifocal imaging device 1 exposes the first incident light; when the rotating component 13 makes the second incident light incident on the lens 21, the bifocal fusing imaging device 1 exposes the second incident light.

When the dual optical fusion imaging device 1 exposes the first incident light, the rotating component 13 makes the first incident light incident to the lens 21 and blocks the second incident light incident to the lens 21; alternatively, the rotating member 13 allows the initial light to pass through the first filter 11 and blocks the initial light from passing through the second filter 12. It can be understood that when the rotating member 13 passes the initial light through the first filter 11 and blocks the initial light from passing through the second filter 12, the initial light only forms the first incident light. Therefore, when the two-light fusion imaging device 1 exposes the first incident light, only the first incident light is incident to the lens 21.

When the bifocal imaging device 1 exposes the second incident light, the rotating assembly 13 makes the second incident light incident on the lens 21 and blocks the first incident light from being incident on the lens 21; alternatively, the rotating member 13 makes the initial light pass through the second filter 12 and blocks the initial light from passing through the first filter 11. It is understood that when the rotating member 13 passes the initial light through the second filter 12 and blocks the initial light from passing through the first filter 11, the initial light only forms the second incident light. Therefore, when the two-photon fusion imaging device 1 exposes the second incident light, only the second incident light is incident on the lens 21.

The rotating assembly 13 includes a rotating member 131, a light transmitting member 132, and a rotating motor 133. In this embodiment, the rotating member 131 is disposed on the rotating motor 133, and the rotating motor 133 can drive the rotating member 131 to rotate. The light-transmitting member 132 is disposed on the rotating member 131 and can rotate around the rotating member 131. Specifically, one end of the rotation member 131 is fixed to the rotation motor 133, and the other end is provided with the light transmitting member 132. When the rotating motor 133 drives the rotating member 131 to rotate, the rotating member 131 drives the light-transmitting member 132 to rotate together. Among them, the rotating motor 133 is two high-speed motors.

In the present embodiment, the light-transmitting member 132 includes a light-shielding portion 1321 and a light-transmitting portion 1322. Here, the light can pass through the light-transmitting portion 1322, but cannot pass through the light-shielding portion 1321. Preferably, the light-transmitting member 132 is an axisymmetric pattern, and the light-blocking portion 1321 and the light-transmitting portion 1322 are symmetric with respect to the symmetry axis of the light-transmitting member 132. The light-transmitting member 132 is a black-and-white color wheel, in which a white half is a light-transmitting portion 1322 and a black half is a light-shielding portion 1321. Specifically, the center of the light-transmitting member 132 is fixed to the rotation member 131, and the first filter 11 and the second filter 12 are symmetrically disposed about the rotation member 131.

When the light-transmitting member 132 rotates to the position where the light-transmitting portion 1322 faces the first filter 11 and the light-shielding portion 1321 faces the second filter 12, only the first incident light enters the lens 21. When the light-transmitting member 132 rotates to the position where the light-transmitting portion 1322 faces the second filter 12 and the light-shielding portion 1321 faces the first filter 11, only the second incident light enters the lens 21. In the present embodiment, the size of the light-transmitting member 132 is adapted to the positions and sizes of the first filter 11 and the second filter 12. Regardless of the position and size of the first filter 11 and the second filter 12, when the light-transmitting portion 1322 is aligned with the first filter 11 or the second filter 12, the projection of the first filter 11 or the second filter 12 completely falls within the light-transmitting portion 1322; when the light shielding portion 1321 is aligned with the first filter 11 or the second filter 12, the projection of the first filter 11 or the second filter 12 is to fall completely within the range of the light shielding portion 1321.

In the present embodiment, after the first incident light is incident on the lens 21, the light-transmitting member 132 rotates 180 °, so that the second incident light is incident on the lens 21. Then, the light-transmitting member 132 rotates 180 ° again, so that the first incident light is incident on the lens 21, and the cycle is repeated. Meanwhile, when only the first incident light is incident to the lens 21, the bifocal fusion imaging device 1 exposes the first incident light; when only the second incident light is incident on the lens 21, the bifocal imaging device 1 exposes the second incident light. It can be understood that, during the rotation of the light-transmitting member 132, there may be a case where the first incident light and the second incident light are simultaneously incident on the lens 21, and at this time, the bifocalization imaging apparatus 1 does not perform the exposure operation.

The light-transmitting member 132 is disposed on one side of the first filter 11 and the second filter 12 close to the lens 21, or the light-transmitting member 132 is disposed on one side of the first filter 11 and the second filter 12 far away from the lens 21.

When the light-transmitting member 132 is disposed on one side of the first filter 11 and the second filter 12 close to the lens 21, and the light-transmitting portion 1322 faces the first filter 11 and the light-shielding portion 1321 faces the second filter 12, a part of the initial light passes through the first filter 11 to form a first incident light, and passes through the light-transmitting portion 1322 to enter the lens 21; another portion of the original light rays passes through the second filter 12 to form a second incident light, but the second incident light is blocked by the light blocking portion 1321.

When the light-transmitting member 132 is disposed on one side of the first filter 11 and the second filter 12 close to the lens 21, and the light-transmitting portion 1322 faces the second filter 12 and the light-shielding portion 1321 faces the first filter 11, a part of the initial light passes through the first filter 11 to form a first incident light, but the first incident light is blocked by the light-shielding portion 1321; another part of the original light passes through the second filter 12 to form a second incident light, and passes through the light-transmitting portion 1322 to enter the lens 21.

When the light-transmitting member 132 is disposed on the sides of the first filter 11 and the second filter 12 away from the lens 21, and the light-transmitting portion 1322 faces the second filter 12 and the light-shielding portion 1321 faces the first filter 11, a part of the initial light is blocked by the light-shielding portion 1321; another part of the original light passes through the light-transmitting portion 1322, and passes through the second filter 12 to form a second incident light, which is incident to the lens 21.

The first set of mirrors 14 is located on the side of the second set of mirrors 15 remote from the rotator 131. Specifically, the first mirror 143 is located on a side of the third mirror 153 remote from the rotatable member 131, and the second mirror 144 is located on a side of the fourth mirror 154 remote from the rotatable member 131.

The first set of mirrors 14 comprises a first entrance face 141 and a first exit face 142 and the second set of mirrors 15 comprises a second entrance face 151 and a second exit face 152. The first incident surface 141 and the second exit surface 152 are parallel, and the first exit surface 142 and the second incident surface 151 are parallel and opposite to each other. Specifically, the first incident surface 141 is a surface of the first reflecting mirror 143 and the second reflecting mirror 144 away from the mirror 21, and the first exit surface 142 is a surface of the first reflecting mirror 143 facing the third reflecting mirror 153 and a surface of the second reflecting mirror 144 facing the fourth reflecting mirror 154.
