Referring to fig. 1 to 3, which respectively show a perspective view, an exploded view and a projection view in one direction of a camera module 1 according to an embodiment of the present invention, the camera module 1 includes a prism 100, a first image sensor 200, a second image sensor 300 and an image synthesis element. The prism 100 has an incident surface 120, a first side surface 130, and a second side surface 140; along the set direction Z, the first side 130 and the second side 140 are close to each other. The first image sensor 200 is used for receiving the light entering the prism 100 through the incident surface 120 and reflected by the first side surface 130. The second image sensor 300 is used for receiving the light entering the prism 100 through the incident surface 120 and reflected by the second side surface 140. The first view field acquired by the first image sensor 200 and the second view field acquired by the second image sensor 300 are partially overlapped, and the first view field and the second view field jointly form the view field of the camera module 1. The image synthesizing element is connected to the first image sensor 200 and the second image sensor 300, respectively, and synthesizes an image formed by the first image sensor 200 and an image formed by the second image sensor 300. The term "set direction" in this document specifically means: perpendicular to the incident surface 120 and pointing from the incident surface 120 to the direction inside the prism 100. It should be noted that the dotted lines in fig. 3 show the propagation paths of the light.
As to the prism 100, please refer to fig. 1 to 3, the prism 100 is disposed between the first image sensor 200 and the second image sensor 300, and is an element for guiding the light outside the camera module 1 to the first image sensor 200 and the second image sensor 300 respectively. In this embodiment, the prism 100 specifically has two end surfaces 110, an incident surface 120, a first side surface 130, and a second side surface 140. Specifically, the two end surfaces 110 are disposed to face each other, and the two end surfaces 110 constitute two bottom surfaces of the prism 100. The incident surface 120 extends from one end surface 110 to the other end surface 110, which is a surface through which light is transmitted into the prism 100. The first side surface 130 and the second side surface 140 are both located on the same side of the incident surface 120, and both are disposed obliquely to the incident surface 120. Along the set direction Z, the first side surface 130 gradually approaches the second side surface 140, and the second side surface 140 also gradually approaches the first side surface 130; this arrangement causes the primary area of the first field of view acquired by the first image sensor 200 to be tilted to the left as viewed in fig. 3 and the primary area of the second field of view acquired by the second image sensor 300 to be tilted to the right as viewed in fig. 3, i.e., the total field of view acquired by both image sensors together is greater than the field of view acquired by a single image sensor. The first side surface 130 is a surface for reflecting a part of the light after the light enters the prism 100, and the reflected light is emitted to the first image sensor; the second side surface 140 is a surface on which the light enters the prism 100, reflects part of the light, and directs the reflected light to the second image sensor 300.
Preferably, the first side surface 130 and the second side surface 140 form an acute angle therebetween, and the acute angle is between 50 ° and 70 °. In this embodiment, an included angle between any two of the incident surface 120, the first side surface 130, and the second side surface 140 is 60 °, that is, the acute angle is 60 °; of course, in other embodiments of the present invention, the included angle between the first side 130 and the second side 140 can be adjusted within the above-mentioned range.
Preferably, the prism 100 has a prism structure, the two end surfaces 110 form bottom surfaces of the prism structure, and the incident surface 120, the first side surface 130, and the second side surface 140 form side surfaces of the prism structure. The prism-like structure ensures that the first side surface 130 and the second side surface 140 have the same area, thereby facilitating alignment of the first field of view acquired by the first image sensor 200 and the second field of view acquired by the second image sensor 300 in a direction perpendicular to the end surface 110. Alternatively, the prism 100 is a triangular prism, that is, the incident surface 120, the first side surface 130 and the second side surface 140 intersect with each other two by two. It is understood that in other embodiments of the present invention, the prism 100 may also be a prism with a number of sides greater than 3; for example, in some other embodiments of the present invention, the prism 100 has a quadrangular prism structure, and specifically, a connection surface is further disposed between the incident surface 120 and the first side surface 130, and the connection surface connects the first side surface 130, the second side surface 140, and the two end surfaces 110, respectively.
With reference to fig. 1 to fig. 3, the first image sensor 200 is disposed close to the prism 100 and on a side of the second side 140 away from the first side 130, with reference to the first image sensor 200 and the second image sensor 300. The light received by the first image sensor 200 enters the prism 100 through the incident surface 120, is reflected by the first side surface 130, and then exits the prism 100 through the second side surface 140; the first image sensor 200 is used for receiving the light emitted from the second side 140 of the prism 100 and imaging according to the light received by the first image sensor. Similarly, the second image sensor 300 is also disposed near the prism 100 and on a side of the first side 130 opposite to the second side 140. The light received by the second image sensor 300 enters the prism 100 through the incident surface 120, is reflected by the second side surface 140, and then exits the prism 100 through the first side surface 130; the second image sensor 300 is configured to receive the light emitted from the first side 130 of the prism 100 and form an image according to the received light. The first view field acquired by the first image sensor 200 is partially overlapped with the second view field acquired by the second image sensor 300, and the first view field and the second view field form a continuous view field of the camera module 1, so that continuous and complete images formed by the camera module 1 are ensured.
Further, in order to orderly guide the light emitted from the second side surface 140 to the first image sensor 200, the camera module 1 further includes a first lens 500. Specifically, please refer to fig. 2 and fig. 3, the first lens 500 is located between the prism 100 and the first image sensor 200; the first lens 500 is a combination of several lenses for guiding and presenting the light emitted from the second side surface 140 to the first image sensor 200.
Further, in order to sequentially guide the light emitted from the first side 130 to the second image sensor 300, the camera module 1 further includes a second lens 600. Specifically, please continue to refer to fig. 2 and fig. 3, the second lens 600 is located between the prism 100 and the second image sensor 300; the second lens 600 is a combination of lenses for guiding and presenting the light emitted from the first side 130 to the second image sensor 300.
In some embodiments, the edge of the incident surface 120 and the end surface 110 are provided with a light-shielding material layer (not shown) for blocking light from passing through, and the light-shielding material layer specifically covers the entire end surface 110, the edge area of the incident surface 120, and the edge where the incident surface 120 intersects with other surfaces, so that when the camera module 1 is installed in an electronic device, external light is prevented from passing through the area covered by the light-shielding material layer and falling onto the first image sensor 200 and the second image sensor 300, thereby causing a disadvantage of generating excessive noise when the first image sensor 200 and the second image sensor 300 are imaged. Alternatively, the light-shielding material layer may include ink, and the light-shielding material layer may be printed on the corresponding surface of the prism 100 by silk-screening. It is understood that, in other embodiments of the present invention, the light-shielding material layer may also be made of other materials such as opaque metal foil layer, insulating gummed paper, etc., and the light-shielding material layer may also be disposed on the corresponding surface by a method other than printing, which is not limited herein; in addition, the light-shielding material layers on different surfaces of the prism 100 may be made of the same or different materials, and the invention is not limited thereto as long as the light-shielding material layers on the surfaces can prevent light from passing through. Further, the incident surface 120 is provided with an anti-reflection film to increase the ratio of light transmitted on the surface and reduce the ratio of light reflected on the surface. Considering that the edge of the incident surface 120 is provided with the light-shielding material layer, the antireflection film provided on the incident surface 120 is located in the region surrounded by the light-shielding material layer; of course, in other embodiments of the present invention, if the incident surface 120 is not provided with a light-shielding material layer, the antireflection film may cover the entire surface of the incident surface 120. The materials and forming methods of the antireflection film are well known in the art, and will not be described in detail here.
Further, in order to facilitate the camera module 1 to be installed in an electronic device, the first image sensor 200 and the second image sensor 300 can be communicatively connected to a circuit board and the image combining element in the electronic device, and the camera module 1 further includes a first flexible circuit board 210 and a second flexible circuit board 310. In this embodiment, one end of the first flexible circuit board 210 is connected to the first image sensor 200, and the other end extends toward the second image sensor 300; one end of the second flexible circuit board 310 is connected to the second image sensor 300, and the other end extends toward the first image sensor 200. When the camera module 1 is mounted on a circuit board of an electronic device, the whole camera module occupies a smaller area of the circuit board. In other embodiments of the present invention, the end of the first flexible circuit board 210 away from the connection with the first image sensor 200 extends toward the side away from the second image sensor 300, and the end of the second flexible circuit board 310 away from the connection with the second image sensor 300 extends toward the end away from the first image sensor 200; compared with the mode, the arrangement mode occupies larger surface area of the circuit board, so that the area of other components on the circuit board which can be distributed is reduced.
In this embodiment, along the setting direction Z, the first flexible circuit board 210 is located between two ends of the first image sensor 200; that is, an end of the first flexible circuit board 210, which is away from a connection with the first image sensor 200, protrudes from a side portion (shown in fig. 2) of the first image sensor 200 and extends toward the second image sensor 300. Along the above-mentioned set direction Z, the second flexible circuit board 310 is located between two ends of the second image sensor 300; that is, an end of the second flexible circuit board 310, which is far from a connection point with the second image sensor 300, protrudes from a side portion (shown in fig. 2) of the second image sensor 300 and extends toward the first image sensor 200. In addition, the first flexible circuit board 210 and the second flexible circuit board 310 are disposed on the same side of the first image sensor 200 along a direction in which one end surface 110 points to the other end surface 110; it is understood that, in other embodiments of the present invention, the first flexible circuit board 210 and the second flexible circuit board 310 may also be located on opposite sides of the first image sensor 200 along the direction.
Of course, other embodiments of the present invention can be adapted to the above-described embodiments. For example, in other embodiments of the present invention, along the setting direction Z, the first flexible circuit board 210 is at least partially located on a side of the first image sensor 200 facing away from the incident surface 120; along the setting direction Z, the second flexible circuit board 310 is at least partially located on a side of the second image sensor 300 facing away from the incident surface 120. That is, the end of the first flexible circuit board 210 away from the connection with the first image sensor 200 extends toward the second image sensor 300 after passing through the bottom of the first image sensor 200 (refer to fig. 2); an end of the second flexible circuit board 310, which is away from a connection point with the second image sensor 300, extends toward the first image sensor 200 after passing over a bottom portion (refer to fig. 2) of the second image sensor 300.
Referring to fig. 4, the image combining element 400 is shown in a schematic view of electrical connections among the image combining element 400, the first image sensor 200 and the second image sensor 300, and in conjunction with fig. 1 to 3, the image combining element 400 is respectively connected to the first image sensor 200 and the second image sensor 300, and is configured to combine images formed by the first image sensor 200 and the second image sensor 300 into a complete image. In some embodiments, the Image synthesizing element 400 is an ISP (Image Sensor Processor), which may be integrated in one of the first Image Sensor 200 and the second Image Sensor 300 or integrated on a circuit board of the electronic device, and the invention is not limited to the location thereof. The image composition element 400 performs a predetermined program to stitch together the images of the first image sensor 200 and the second image sensor 300. It should be noted that, since the respective fields of view acquired by the first image sensor 200 and the second image sensor 300 are partially overlapped, when the images formed by the two image sensors are spliced, the image synthesis element 400 needs to perform processing such as stacking or cutting the same image area so that the obtained image is consistent with the actual scene of the outside world. In other embodiments of the present invention, the image synthesizing element 400 may be another element having an image synthesizing function, such as a DSP (digital Signal Processor), a microprocessor, or a Processor.
The camera module 1 according to the embodiment of the present invention includes a prism 100, a first image sensor 200, a second image sensor 300, and an image synthesis element. The prism 100 has an incident surface 120, a first side surface 130 and a second side surface 140; and the first side surface 130 and the second side surface 140 are close to each other along the set direction Z. The first image sensor 200 is used for receiving the light entering the prism 100 through the incident surface 120 and reflected by the first side surface 130. The second image sensor 300 is used for receiving the light entering the prism 100 through the incident surface 120 and reflected by the second side surface 140. The first view field acquired by the first image sensor 200 and the second view field acquired by the second image sensor 300 are partially overlapped, and the first view field and the second view field jointly form the view field of the camera module.
Since the field of view obtained by the first image sensor 200 and the second image sensor 300 together is wider than that obtained by the wide-angle camera module in the current market through the single image sensor and the single lens, the camera module 1 provided by the embodiment of the present invention can improve the current situation that the field of view of the current camera module is relatively small.
Based on the same inventive concept, the present invention further provides an electronic device 2, please refer to fig. 5, which shows a schematic view of the electronic device 2 according to an embodiment of the present invention, and with reference to fig. 1 to 4, the electronic device 2 includes the camera module 1 according to the embodiment.
By including the camera module 1, the electronic device 2 can improve the relatively small market of the electronic device with the camera module in the current market.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
