Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

In order to solve the problems in the prior art, embodiments of the present invention provide a photographing apparatus, a photographing method, a mobile terminal, and a storage medium, and the following describes in detail a technical solution of the present invention with reference to the accompanying drawings and specific embodiments.

An embodiment of the present invention provides a photographing apparatus, which is applied to a mobile terminal, and fig. 3 is an optional schematic structural diagram of the photographing apparatus according to the embodiment of the present invention, as shown in fig. 3 and 4, the photographing apparatus 300 includes the following structures:

a first camera 301, a second camera 302, a third camera 303, a first filter shifting device 311, a second filter shifting device 312 and a third filter shifting device 313; the first optical filter shifting piece device 311 is arranged on the first camera 301, the second optical filter shifting piece device 312 is arranged on the second camera 302, and the third optical filter shifting piece device 313 is arranged on the third camera 303.

Illustratively, as shown in fig. 4, the first camera 301, the second camera 302, and the third camera 303 are arranged in a straight line.

It should be noted that a CAMERA (CAMERA or WEBCAM), also called a computer CAMERA, a computer eye, an electronic eye, etc., is a video input device, and is widely used in video conferencing, remote medical care, real-time monitoring, etc. The users can have image and voice conversations and communications with each other through the camera on the network. In addition, people can also use the method for various popular digital images, video and audio processing and the like.

Cameras can be divided into two categories, digital cameras and analog cameras. The digital camera can convert the analog video signal generated by the video acquisition equipment into a digital signal, and then store the digital signal in the computer. The video signal captured by the analog camera must be converted into a digital mode through a specific video capture card, and the digital mode can be converted into a computer for use after being compressed. The digital camera can directly capture images and then transmit the images to the computer through a serial port, a parallel port or a USB interface. The camera in the computer market is mainly a digital camera, and the digital camera is mainly a USB digital camera using a novel data transmission interface, and most of the cameras visible in the market are the digital camera. In addition, there is a product used in conjunction with a video capture card, but this is not the mainstream. Due to the rapid popularization of personal computers, the overall cost of the analog camera is high, the BSV liquid crystal splicing screen interface cannot be met, and the like, the transmission speed of the USB interface is far higher than the speed of a serial port and a parallel port, so that the digital camera of the USB interface is sold in the market. The analog camera can be matched with a video acquisition card or a USB video acquisition card for use, is conveniently connected with a computer for use, and is typically applied to general video monitoring. Clean district camera, the embedded special camera in clean district is the special camera to clean district dust free chamber important equipment key post real time monitoring. The camera pure plane panel is embedded with a color steel plate, has zero sanitary dead angle, is clean and convenient to install, can be quickly distributed and controlled at multiple points, and is compatible with a mainstream video system

The camera generally has the basic functions of video shooting/transmission, static image capture and the like, and after images are collected through a lens, the images are processed and converted into digital signals which can be identified by a computer through a photosensitive component circuit and a control component in the camera, and then the digital signals are input into the computer through a parallel port or a USB connection and then are restored through software.

In the prior art, the main structure and components of the camera include: LENS (LENS), LENS structure, consisting of several lenses, including Plastic LENS (Plastic) or Glass LENS (Glass). Image sensors can be classified into two types of CCDs (charge-coupled devices): charge coupled device cmos (complementary metal oxide semiconductor): a complementary metal oxide semiconductor.

It will be appreciated that the filter paddle is a paddle-type structure with a filter that enables selection of the state, and that the filter is an optical device for selecting the desired wavelength band of radiation. One common property of filters is that no filter can make the imaging of celestial objects brighter, since all filters absorb certain wavelengths, thereby making the object darker. Color filters are flat glass or gelatin sheets of various colors with transmission bandwidths of several hundred angstroms, which are commonly used in broadband photometry or in star spectrographs to isolate overlapping spectral orders. The main characteristic is that the size can be made bigger or smaller. Thin film filters generally transmit longer wavelengths and are often used as infrared filters, the latter being on a substrate.

It should be noted that the filter is made of plastic or glass plate and special dye, and the red filter only allows red light to pass through, and so on. The transmittance of the glass sheet is almost the same as that of air originally, all colored light can pass through the glass sheet, so the glass sheet is transparent, but after the glass sheet is dyed with dye, the molecular structure is changed, the refractive index is also changed, and the passing of certain colored light is changed. For example, a white light beam passes through a blue filter, and a blue light beam is emitted, while a little green light and a little red light are absorbed by the filter.

It is understood that the optical filter is widely used in the photographic field, and when a scene is photographed, the optical filter is needed to highlight a main scene. For example, when a day lily is to be shot with a camera and the background is blue sky and green leaf, if the image of the day lily is not prominent enough according to the normal shooting method, the theme of "yellow" color of the flower cannot be highlighted. If a yellow filter is placed in front of the lens, a part of green light scattered by green leaves and blue light scattered by blue sky are blocked, and a large amount of yellow light scattered by yellow flowers passes through, so that the yellow flowers are very obvious and the theme of 'yellow flowers' is highlighted.

Therefore, based on the principle, the optical filter shifting piece device is arranged on each camera in the embodiment of the invention, and it can be understood that the shifting piece device has two states of opening and closing, and then the image shot by each camera can be an image when the shifting piece device is opened or an image when the shifting piece is closed. For example, when the shifting piece is opened, the camera takes an RGB image, otherwise, a monochrome image filtered by the filter is taken.

For example, when the mobile terminal captures an image, the first camera, the second camera, and the third camera may be simultaneously started, or one of the cameras may be started, or the embodiment of the present invention does not specifically limit the number of the started cameras.

For example, when the first camera is started, and the first filter plectrum device is turned on, the first camera shoots a first RGB image; when the first optical filter plectrum device is closed, the first camera shoots a first monochromatic image.

Under the condition that the first camera is started, if the second camera is also started, the second camera shoots a second RGB image under the condition that the second optical filter shifting device is opened; and under the condition that the second optical filter plectrum device is closed, the second camera shoots a second monochromatic image.

Under the condition that the first camera and the second camera are started, if the third camera is also started, under the condition that the third optical filter shifting device is opened, the third camera shoots a third RGB image; and under the condition that the third filter plectrum device is closed, the third camera shoots a third monochromatic image.

Therefore, it can be understood that, in the case where one camera is turned on, one RGB image, or a monochrome image, can be obtained; under the condition that two cameras are simultaneously opened, one RGB image and one monochrome image, or two RGB images or two monochrome images can be obtained; in the case where three cameras are simultaneously turned on, one RGB image and two monochrome images, or two RGB images and one monochrome image, or three RGB images, or three monochrome images can be obtained.

Therefore, when a user needs to obtain a single-color image, the single-color image can be obtained only by determining the state of the corresponding pick device, more than one single-color image can be obtained at the same time, namely one single-color image, two single-color images or three images, and simultaneously an RGB image can also be obtained, and the single-color image and the RGB image are subjected to special effect processing.

In an implementation manner of the present invention, the first optical filter shifting device is a red optical filter, the second optical filter shifting device is a green optical filter, and the third optical filter shifting device is a blue optical filter. Then, the obtained monochrome image may be a red image, a green image, and a blue image.

It will be appreciated that with the first camera on, an RGB image, or a red image, may be obtained; under the condition that the first camera and the second camera are simultaneously opened, an RGB image and a red image, or two RGB images, an RGB image and a blue image, an RGB image and a green image can be obtained; or one blue image one green image, one blue image one red image, one red image one green image.

Under the condition that the three cameras are simultaneously opened, an RGB image, a red image and a green image can be obtained; an RGB image, a red image and a blue image; an RGB image, a green image and a blue image; or two RGB images and one blue image, or two RGB images and one green image, or two RGB images and one red image, or three RGB images, or three monochrome images.

It can be understood that RGB is three primary colors, and the effect of the picture special effect processing can be further enhanced by setting the filter segments of the three primary colors.

The distribution positions of the first camera 301, the second camera 302 and the third camera 303 are arranged in a delta shape.

In order to further facilitate the monochrome image acquisition, in the embodiment of the present invention, the first filter shifting block device 311, the second filter shifting block device 312 and the third filter shifting block device 313 all include a filter-on mode and a filter-off mode, as shown in fig. 6.

In addition, in an embodiment of the present invention, a signal receiving module 314 is further included in the photographing apparatus, and the signal receiving module 314 is respectively connected to the first camera, the second camera, and the third camera. The obtained image is directly transmitted to the signal receiving module 314, so that the signal receiving module receives the photographed image, thereby transmitting the image to the image processor 1041 of the mobile terminal, as shown in fig. 5.

Compared with the prior art, the photographing device provided by the embodiment of the invention has the advantages that the first optical filter shifting device is arranged on the first camera, the second optical filter shifting device is arranged on the second camera, and the third optical filter shifting device is arranged on the third camera, so that the picture obtained by the first camera can be a single-color picture filtered by the first optical filter shifting device or a panoramic RGB image not filtered by the first optical filter shifting device, the second photographing device can simultaneously obtain three panoramic RGB images and three single-color images filtered by the optical filter shifting device, or a mixture thereof, for example, one RGB image and two monochrome images filtered by the filtering device are obtained, and the application of the photographing device can facilitate special effect processing of images by using the monochrome images or the combination of the RGB images according to the simultaneous obtaining of the RGB images and the monochrome images. Therefore, the problem that the special effect processing effect of the image is poor due to the fact that the mobile terminal in the prior art can only shoot one panoramic image at a time and cannot use the panoramic image for special effect processing is solved.

As shown in fig. 7, the present invention discloses a photographing method, comprising the steps of:
