Detailed Description

The present application will now be described in further detail with reference to the accompanying drawings and specific examples.

It should be noted that, in the case of no conflict, the technical features in the examples and examples of the present application may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as an improper limitation of the present application.

Referring to fig. 1 and 2, the camera 123 according to the present invention includes a lens 1231, a Sensor (image Sensor) 1232, a PCB (printed circuit board) 1233, and a holder 1234. The Sensor1232 includes, but is not limited to, a CCD (charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor). The Sensor1232 is fixed to the PCB 1233, the holder 1234 is disposed at a side of the Sensor1232 close to the subject 20 and connected to the PCB 1233, the holder 1234 is provided with a cavity for accommodating the lens 1231, and the lens 1231 is opposite to the Sensor 1232. In the photographing process, light of the object 20 enters the camera 123, incident light first enters the lens 1231 and then reaches the Sensor1232, photons in the light strike the Sensor1232 to generate movable charges, which is an internal photoelectric effect, the movable charges are collected to form electric signals, Digital-to-analog conversion is performed through an a/D converter, that is, the electric signals are converted into Digital signals, the Digital signals are sent to a Digital Signal Processor (DSP) for processing, and finally the Digital signals are transmitted to the screen 17 of the terminal device to form a display image, so that photographing of the object 20 is realized. Specifically, the DSP includes an ISP (Image Signal Processor) and a JPEG encoder (JPEG Image decoder), wherein the ISP is a key for determining the smoothness of the Image. It will be appreciated that for CMOS, the DSP may be integrated within the CMOS. The CMOS has the advantages of high integration level, low power consumption, low cost and the like, and is more suitable for mobile phones with limited internal space.

The PCB 1233 may be a hard board, a soft board, or a rigid-flex board. When the mobile phone adopts the CMOS, the CMOS can be applied to any one of a hard board, a soft board, or a rigid-flex board. When the mobile phone adopts the CCD, only the rigid-flexible board can be used, and the rigid-flexible board has the highest price among the three boards, so that when the CCD is adopted, the cost of the mobile phone is higher.

In some embodiments, the camera may be a macro camera, which refers to a camera that performs shooting at a larger optical magnification when being closer to the object under the premise of ensuring that the object is clearly imaged, through the optical power of the lens 1231, where the optical magnification refers to a ratio between an imaging height of the sensor and a height of the object.

It should be noted that, the magnification sensed by the user is an optical magnification, i.e., a screen magnification, i.e., a digital magnification, the optical magnification refers to a ratio of a height of an image formed on the sensor to a height of the subject, the screen magnification refers to a ratio of a screen size to a sensor size, and the digital magnification is a ratio of a size on the screen after the user manually enlarges a part of the screen to generate enlargement of the same part to a size on the screen before enlargement. Specifically, for example, as shown in fig. 2, light reflected by the object to be photographed 20 reaches the Sensor1232 after passing through the lens 1231, and then an electrical signal is generated, and is converted into a digital signal by the analog-to-digital conversion device, and the digital signal is processed by the DSP digital signal processing chip and transmitted to the screen 17 of the mobile terminal to form an image, and the user can magnify a part of the image on the screen 17 as needed, and the image displayed on the screen 17 is the screen magnified image 30.

Specifically, according to the basic optical imaging principle, tan (FOV/2) is the imaging height/focal length which is the subject height/object distance, and the optical magnification is the imaging height/subject height which is the focal length/object distance. Wherein, fov (field Of view) is the angle Of view, which is the angle formed by two sides Of the optical instrument that the center Of the lens Of the optical instrument is the vertex and the measured or shot object can pass through the maximum range Of the center Of the lens. The FOV is typically measured as the field of view of the lens, e.g., a conventional standard lens with an angle of view around 45 degrees and a wide-angle lens 1231 with an angle of view above 60 degrees. According to the above formula for calculating the optical magnification, the increase of the optical magnification can be achieved by decreasing the working distance or increasing the focal length, that is, on the premise of ensuring clear imaging, the lens 1231 is as close to the object to be photographed as possible and the focal length of the lens 1231 is increased. The working distance is a distance from the subject to the front end of the lens.

According to the gaussian imaging formula, 1/f is 1/u + 1/v. Wherein f is the focal length; u is the object distance; v is the image distance;

when u is larger than 2f, the shot object forms a reduced inverted real image on the Sensor 1232;

when u is 2f, v is f, namely the focal length is equal to the image distance, the shot object forms an equal-size inverted real image on the Sensor 1232;

when f < u <2f, the shot object forms an enlarged inverted real image on the Sensor 1232;

when u is f, the shot object does not form an image on the Sensor 1232;

when u < f, it is a virtual image, and the subject cannot be imaged on Sensor1232 in real.

Therefore, v and u have opposite changing trends with constant focal length f, and v decreases with increasing u and v increases with decreasing u. Since macro photography is a photography method for obtaining an enlarged image of an object in a close range, that is, the object is an enlarged real image on a Sensor, when close range macro photography is performed, the object distance u is relatively small, and the working distance is also relatively small, so that the focal length of the lens 1231 needs to be smaller to satisfy the requirement of focusing, so as to ensure that f < u <2f, and the image distance and the object distance satisfy the gaussian imaging formula.

The internationally acknowledged statement in the photographic world is that the shooting of optical magnification of about 1: 1 ~ 1: 4 all belongs to the macro photography, and in the embodiment of the application, the super-macro camera refers to a macro camera that can still realize focusing when the working distance is less than 10mm, namely the sensor can still clearly image when the working distance is less than 10 mm. In the present embodiment, "less than" does not include the number. In one embodiment, the ultramicro-distance range is 3mm to 9 mm. That is, when the working distance is 3mm to 9mm, the ultramicro camera can form images, and can clearly form images on the Sensor 1232.

The ultramicro-distance camera can be a long-focus ultramicro-distance lens or a wide-angle ultramicro-distance lens. Illustratively, the focal length f of the wide-angle ultramicro lens ranges from 1.3mm to 2.2mm, and the FOV is 70 ° to 78 °, illustratively, the effective focal length f of the wide-angle ultramicro lens is 1.335mm, the FOV at the maximum image height is 77.6 °, the aperture value (f-number) is 2.8, and clear imaging can be performed when the working distance is 3mm, that is, the lens 1231 can focus on a shot object with the working distance of about 3 mm.

In the embodiments of the present application, the number of fingers is two or more.

In the embodiment of the application, the field of view refers to an area where a shot object can be seen on a screen of the mobile terminal; the object side refers to a side close to the subject.

The mobile terminal in the embodiment of the present application may include a mobile phone, a notebook computer, a tablet computer, a PDA (Personal Digital Assistant), a portable computer, and other terminal devices. For convenience of description, in the embodiment of the present application, a mobile terminal is taken as an example for description.

An embodiment of the present application provides a camera module, please refer to fig. 3, the camera module 12 includes: camera 123, light filling light source 122 and leaded light 121. The light guide member 121 has a first avoiding opening 121a and a first installation space 121d disposed around the first avoiding opening 121a, and one end of the camera 123 close to the object side is inserted into the first avoiding opening 121a, which is equivalent to the light guide member 121 surrounding the camera 123. The light supplement light source 122 is disposed in the first installation space 121d, which is equivalent to the light supplement light source 122 hidden in the light guide member 121. The light of the fill-in light source 122 is guided to the field of view of the camera 123 by the light guide 121.

The mobile terminal 10 of the embodiment of the application, the one end of the camera 123 close to the object side is inserted into the first avoiding opening 121a of the light guide 121, and the light supplement light source 122 is disposed in the first installation space 121d of the light guide 121, so that the light of the light supplement light source 122 can be guided to the view field of the camera 123 from the periphery of the camera 123, thereby providing sufficient illumination for the view field of the camera 123 in the close-range shooting mode, and further, the shot object 20 in the view field can be clearly shot.

In addition, the light supplementing light source 122 is disposed in the first installation space 121d of the light guide member 121, so that light guiding is facilitated, and the overall structure of the camera module 12 can be more compact.

Referring to fig. 6, the light guide member 121 of the embodiment of the present application is a continuous annular structure, and specifically, the light guide member 121 of the embodiment of the present application is a circular ring. For improving the uniformity of light filling, this application embodiment has set up a plurality of light filling light sources 122, and a plurality of light filling light sources 122 set up along camera 123's circumference interval, and the contained angle size between two adjacent light filling light sources 122 can be the same, also can be different.

It is understood that the light guide 121 is not limited to be circular, and in other embodiments, the outer ring of the annular light guide 121 may also be rectangular, triangular, elliptical, irregular, etc., and the inner ring may be any one of circular, rectangular, triangular, elliptical, irregular, etc., that is, the outer ring and the inner ring of the annular light guide 121 may be the same shape or different shapes, which is not limited herein.

In other embodiments, the light guide member 121 may not be a continuous ring structure, for example, referring to fig. 7, in another embodiment, the light guide member 121 may include a plurality of sub light guide members 1211, and the sub light guide members 1211 are spaced apart from each other to form the first avoiding opening 151 a. Similarly, to improve the uniformity of the fill-in light, one or more fill-in light sources 122 may be disposed in each sub light guide 1211.

The Light supplement Light source 122 according to the embodiment of the present application may be any one of an LED (Light Emitting Diode) lamp, a metal halide lamp, a fluorescent lamp, a high-pressure sodium, an incandescent lamp, a tungsten-iodine lamp, and a xenon lamp. Illustratively, in an embodiment, the light supplement light source 122 is an LED lamp, which operates stably, generates low heat, consumes low energy, and has a long service life.

Referring to fig. 3, one end of the first avoiding opening 121a of the embodiment of the present application has a first opening, and the other end of the first avoiding opening has a second opening. The first avoiding opening 121a at least has a contracting section 121b, the contracting section 121b gradually contracts from one end where the first opening is located toward one end where the second opening is located, and the first installation space 121d is located on the peripheral side of one end of the first avoiding opening 121a close to the second opening. That is to say, the aperture of the side of the contracting section 121b close to the first opening is larger than the aperture of the side of the contracting section 121b far away from the first opening, so that when the camera 123 shoots, the light reflected by the object 20 can be incident on the camera 123, and finally imaging is realized.

In this embodiment, the first avoiding opening 121a has a contracting section 121b and a straight section, the straight section is connected to one end of the contracting section 121b away from the first opening, the first opening of the first avoiding opening 121a is equivalent to the opening of the contracting section 121b, the second opening is equivalent to the opening of the straight section, and the first installation space 121d is actually located on the periphery side of the straight section. In other embodiments, the straight line segment may be connected to an end of the contracting section 121b away from the second opening, or both ends of the contracting section 121b may be provided with the straight line segment. In other embodiments, no straight line segment may be provided.

Referring to fig. 3, in the embodiment of the present application, the sidewall of the contraction section 121b is a light emitting surface 121c of the light guide 121. That is to say, after the light of the light supplement light source 122 enters the light guide 121 from the light incident surface 121e of the light guide 121, the light can be emitted from the side wall of the contraction section 121b and guided to the view field of the camera 123, which is equivalent to that the first avoiding opening 121a is not only the shooting hole of the camera 123 but also the light emitting hole of the camera module 12, so that it can be ensured that the relative illumination in the view field can meet the shooting requirement when the camera 123 shoots, especially shoots in a close range.

In other embodiments, the light emitted by the light supplement light source 122 may enter the light guide 121 from the light incident surface 121e of the light guide 121, and then be reflected for multiple times in the light guide 121 and transmitted to the light emitting surface 121c of the light guide 121.

It is understood that, in other embodiments, a light exit hole may be separately provided at the periphery of the first avoidance port 121a, and the light guided out through the light guide 121 is guided to the field of view of the camera 123 through the light exit hole, that is, the first avoidance port 121a is used only as a shooting hole of the camera 123, and the light guided out from the light guide 121 does not pass through the first avoidance port 121 a.

The side wall of the contraction section 121b may not be a light exit surface, for example, in other embodiments, an end surface of the light guide member 121 on the side provided with the first opening may be a light exit surface.

Referring to fig. 3, in the embodiment of the present application, a portion of the end surface having the second opening is recessed toward the end surface having the first opening to form a first installation space 121d, in other embodiments, a portion of the sidewall of the light guide member 121 is recessed toward the first avoiding opening 121a to form a first installation space 121d, and the first installation space 121d may be disposed inside the light guide member 121.

Further, referring to fig. 3, the light incident surface 121e of the light guide member 121 according to the embodiment of the present disclosure is located at a side of the first installation space 121d close to the first avoiding opening 121 a. Specifically, the light incident surface 121e of the present embodiment is parallel to the optical axis a of the camera 123, so that the light supplement light source 122 is conveniently arranged in the first installation space 121d, and the light of the light supplement light source 122 is conveniently guided to the side wall of the contraction section 121b from the light incident surface 121e and emitted from the side wall of the contraction section 121 b.

In other embodiments, the light incident surface 121e may not be parallel to the optical axis a of the camera 123. For example, the light incident surface 121e may have a certain included angle with the optical axis a, and further, in an embodiment, the light incident surface 121e may be perpendicular to the optical axis a.

In addition, since the light guide member 121 is made of a light-transmitting material, in order to prevent the user from seeing the internal structure of the mobile terminal 10 through the light guide member 121, the end surface of the light guide member 121 having the second opening may be set as a non-light-transmitting surface, for example, the end surface of the light guide member 121 having the second opening may be atomized to achieve a frosted effect.

Referring to fig. 4, a mobile terminal 10 according to another embodiment of the present application further includes a housing 11, a main board 13, and a camera module 12 according to the foregoing embodiment.
