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.

In the description of the present application, the terms of "vertical," "horizontal" orientation or positional relationship are based on the orientation or positional relationship shown in fig. 3, it being understood that these terms of orientation are merely for convenience in describing the present application and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered as limiting the present application.

The mobile terminal 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. The camera 13 is a component of the mobile terminal, and can implement a photographing function of the mobile terminal.

As shown in fig. 1 and 2 in particular, the camera 13 includes a lens 131, a Sensor (image Sensor) 132, a PCB (printed circuit board) 133, and a holder 134. The Sensor132 includes, but is not limited to, a CCD (charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor). The Sensor132 is fixed on the PCB board 133, the holder 134 is disposed on a side of the Sensor132 close to the object 30 and connected to the PCB board 133, and the holder 134 is provided with a cavity for accommodating the lens 131, the lens 131 being opposite to the Sensor 132. In the photographing process, light of the object 30 enters the camera 13, incident light first enters the lens 131 and then reaches the Sensor132, photons in the light strike the Sensor132 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 15 of the terminal device to form a display image, namely, photographing of the object 30 is achieved. 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 installation space.

The PCB board 133 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 the embodiment of the present application, the camera 13 can perform close-range macro photography, and macro photography refers to that, on the premise of ensuring that an image of a photographed object is clear, the terminal device photographs at a higher optical magnification when being closer to the photographed object through the optical capability of the lens 131, wherein the optical magnification refers to a ratio between an imaging height of a Sensor and a height of the photographed object.

It should be noted that, the magnification sensed by the user is an optical magnification, a screen magnification, 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 object, the screen magnification refers to a ratio of a screen size to the Sensor size, and the digital magnification refers to 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 30 reaches the Sensor132 after passing through the lens 131, 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 15 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 15 as needed, and the image displayed on the screen 15 is the screen magnified image 40.

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 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 131 is as close to the object as possible and the focal length of the lens 131 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 132; 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 132; when f < u <2f, the shot object forms an enlarged inverted real image on the Sensor 132; when u is f, the shot object does not form an image on the Sensor 132; when u < f, it is a virtual image, the subject cannot be imaged on the Sensor132 in real. Therefore, to meet the requirement of focusing, the focal length of the lens 131 needs to be smaller to ensure that f < u <2f, and the image distance and the object distance satisfy the above-mentioned gaussian imaging formula.

The superposition shooting in the present application refers to superposing the camera 13 and the lens assembly 21 built in the mobile terminal to form a composite camera, more specifically, the lens assembly 21 is an object side of the lens 131 superposed in the camera 13, and the lens assembly 21 and the lens 131 jointly form the composite lens. According to the different types of the lens assembly 21 and the lens assembly 131, various types of composite lenses can be combined, taking super-macro superposition shooting as an example, when super-macro superposition shooting is required, the lens assembly 21 is superposed on the object side of the lens 131, the lens assembly 21 and the lens 131 jointly form the composite super-macro lens, incident light sequentially passes through the lens assembly 21 and the lens 131, when super-macro superposition shooting is not required, the lens assembly 21 is removed, and shooting is directly carried out by adopting the camera 13.

The internationally acknowledged statement in the photographic world is that shooting with optical magnification of about 1: 1-1: 4 belongs to macro photography, and in the embodiment of the application, the composite macro lens refers to a macro lens which can still realize focusing when the working distance is less than 10mm, namely, a 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 composite ultramicro lens can image, and can clearly image on the Sensor 132.

The composite ultramicro lens can be a composite long-focus ultramicro lens or a composite wide-angle ultramicro lens. Illustratively, the focal length f of the compound wide-angle ultramicro-distance lens ranges from 1.3mm to 2.2mm, the FOV of the ultramicro-distance lens ranges from 70 ° to 78 °, illustratively, the effective focal length f of the compound wide-angle ultramicro-distance 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 achieved under the condition that the working distance is 3mm, that is, the compound wide-angle ultramicro-distance lens can focus on a shot object with the working distance of about 3 mm.

For convenience of description, in the embodiment of the present application, a mobile terminal is taken as an example for description.

Through rotating the mounting disc, one of the lens assemblies 21 can be superposed with the camera 13, so that various shooting requirements of users can be met. It is understood that the number of the mounting holes 223a ' may be larger than the number of the lens assemblies 21, for example, at least one mounting hole 223a ' may be left in the mounting plate without the lens assembly 21, when the mounting hole 223a ' without the lens assembly 21 is aligned with the camera 13, it is equivalent to that the main body 10 only uses the camera 13 of itself for shooting, and does not perform the overlay shooting through the lens assembly 21.
