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 12 according to the present invention includes a lens 121, a Sensor (image Sensor) 122, a PCB (printed circuit board) 123, and a holder 124. The Sensor122 includes, but is not limited to, a CCD (charge coupled device), a CMOS (Complementary Metal Oxide Semiconductor). The Sensor122 is fixed on the PCB 123, the holder 124 is disposed on a side of the Sensor122 close to the object 20 and connected to the PCB 123, and the holder 124 is provided with a cavity for accommodating the lens 121, the lens 121 being opposite to the Sensor 122. In the photographing process, light of the object 20 enters the camera 12, incident light first enters the lens 121 and then reaches the Sensor122, photons in the light strike the Sensor122 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, namely, 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 16 of the terminal device to form a display image, so that photographing of the object 20 is realized. Specifically, the structure of 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 board 123 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 capable of performing macro photography, where the macro camera refers to a camera that performs photography at a larger optical magnification when being closer to a photographed object on the premise of ensuring that the photographed object is clearly imaged through the optical power of the lens 121, and the optical magnification refers to a ratio between an imaging height of the sensor and a height of the photographed 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 20 reaches the Sensor122 after passing through the lens 121, and then an electrical signal is generated, and is converted into a digital signal by the analog-to-digital conversion device, and is transmitted to the screen 16 of the mobile terminal to form an image after being processed by the DSP digital signal processing chip, and the user can magnify a part of the image on the screen 16 as needed, and the image displayed on the screen 16 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 121 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 realized by decreasing the working distance or increasing the focal length, that is, on the premise of ensuring clear imaging, the lens 121 is as close to the object to be photographed as possible and the focal length of the lens 121 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 more than 2f, the shot object forms a reduced inverted real image on the Sensor 122;

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 122;

when f < u <2f, the shot object forms an enlarged inverted real image on the Sensor 122;

when u is f, the subject does not form an image on the Sensor 122;

when u < f, it is a virtual image, the subject cannot be imaged on the Sensor122 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 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 121 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 above gaussian imaging formula.

The internationally acknowledged in the photographic world is that photography with optical magnification of about 1: 1 to 1: 4 is macro photography, and in some embodiments, the camera may also be an ultra-macro camera capable of performing ultra-macro photography. The ultra-micro-distance camera refers to a micro-distance camera which 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 122.

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 121 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.

The protection lens 14 mainly plays a role of protecting the camera 12, and after passing through the protection lens 14, the light refracted from the light outgoing surfaces 131d is guided to the field of view of the functional camera 12, and similarly, the light reflected by the object 20 also passes through the protection lens 14 and then enters the camera 12, and finally, imaging is achieved.

Referring to fig. 4, in another embodiment, the second avoiding hole 11b may further include a first sub-hole 11c and a second sub-hole 11d, and the protective lens 14 includes a first sub-lens 141 and a second sub-lens 142.
