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

Example one

The embodiment of the invention provides a photographing method, and fig. 3 is a first schematic flow chart of the photographing method provided by the embodiment of the invention. As shown in fig. 3, the method mainly comprises the following steps:

s301, receiving a photographing instruction.

In the embodiment of the invention, when a user needs to use the function of front-end photographing, a photographing instruction needs to be sent to the terminal, and the terminal photographs according to the received photographing instruction.

It should be noted that the embodiment of the present invention is applied to a situation where the terminal implements a photographing function of the front-facing camera.

It should be noted that, in the embodiment of the present invention, N groups of lens groups are disposed on the edge of the screen of the terminal, where N is a natural number greater than or equal to 2. The terminal can realize the function of shooing of leading camera through the N group's of lens group that sets up on the screen edge.

Fig. 4 is a schematic diagram illustrating an exemplary terminal screen provided with four groups of lenses at an edge thereof according to an embodiment of the present invention. As shown in fig. 4, when N is equal to 4, an upper left lens group 1 is disposed at the upper left of the screen, an upper right lens group 2 is disposed at the upper right of the screen, a lower left lens group 3 is disposed at the lower left of the screen, a lower right lens group 4 is disposed at the lower right of the screen, and the upper left lens group 1, the upper right lens group 2, the lower left lens group 3, and the lower right lens group 4 are convex lens groups.

It is understood that the combination of the upper left lens group 1, the upper right lens group 2, the lower left lens group 3, and the lower right lens group 4 is a combined lens group. That is to say, the combination of the upper left lens group 1, the upper right lens group 2, the lower left lens group 3 and the lower right lens group 4 is a complete front-end camera lens, and each of the upper left lens group 1, the upper right lens group 2, the lower left lens group 3 and the lower right lens group 4 can realize a corresponding photographing function.

It is understood that, in the embodiment of the present invention, since the upper left lens group 1, the upper right lens group 2, the lower left lens group 3 and the lower right lens group 4 are convex lens groups, according to the characteristics of the convex lenses, the edges thereof are thin, the middle thereof is thick, and the surfaces thereof are spherical, the imaging range is large, that is, the photographing range of the terminal can be expanded.

It can be understood that, in the embodiment of the present invention, the larger the value of N, that is, the more lens groups are disposed on the edge of the screen of the terminal, the larger the photographing range of the terminal is.

It should be noted that, in the embodiment of the present invention, the N groups of lens groups may be convex lens groups, because the convex lenses can converge light, and achieve an imaging effect. However, if other lenses capable of achieving the imaging effect appear in the future, the embodiment of the present invention is also applicable, that is, the embodiment of the present invention is not limited to the specific type of the N groups of lenses.

Specifically, the terminal may receive the photographing instruction in a bright screen state or a dead screen state.

For example, when the terminal is in a bright screen state, the user may find and enter a photographing application in the applications of the terminal, select a photographing option, and send a photographing instruction to the terminal. And then, the terminal directly takes a picture.

For example, when the terminal is in the screen-off state, the user can quickly press two volume-down keys on the side surfaces of the terminal, the terminal receives a photographing instruction, the screen-off state is changed into the screen-on state, and the terminal directly photographs after the screen-on state is changed.

It should be noted that, in the embodiment of the present invention, the specific form of the terminal receiving the photographing instruction may be set autonomously by the user in advance on the terminal. Therefore, if a form in which another terminal receives the photographing instruction appears in the future, the embodiment of the present invention is also applicable, that is, the embodiment of the present invention does not limit the specific form in which the terminal receives the photographing instruction.

It can be understood that, in the prior art, a terminal with a full screen needs to leave a fixed setting position for a front camera on a screen, and therefore, a part which cannot be displayed is still left on the screen of the terminal, that is, the full screen is not completely realized, only the screen of the terminal occupies a higher ratio, and such a design affects the layout of the full screen on the terminal, which causes the waste of the full screen space and the visual effect of the terminal screen is poor. However, in the embodiment of the present invention, the lens group of the front camera is decomposed and divided into N lens groups, which are disposed at the edge of the terminal screen, that is, the front camera is hidden, so that the visual effect of the screen is improved on the premise of ensuring the photographing function of the front camera.

S302, obtaining N groups of image information through N groups of lens groups according to the photographing instruction.

In the embodiment of the invention, after the terminal receives the photographing instruction, according to the photographing instruction, a group of image information can be obtained through each group of lens groups in the N groups of lens groups arranged on the edge of the terminal screen, that is, the terminal can obtain the N groups of image information.

It should be noted that, in the embodiment of the present invention, of the N groups of lens groups disposed on the edge of the screen of the terminal, an image sensor, that is, a photosensitive element, is disposed under each group of lens groups. That is, the terminal is further provided with N image sensors, which correspond to the N groups of lens groups one to one.

It should be noted that, in the embodiment of the present invention, the image sensor may be a charge coupled device or a metal oxide semiconductor device. The charge coupled device is generally used in a terminal with a higher requirement for image quality, and the metal oxide semiconductor device is generally used in a terminal with a lower requirement for image quality. Specific image sensors embodiments of the present invention are not limited.

Specifically, in the embodiment of the present invention, the terminal projects the light transmitted by each group of lens groups in the N groups of lens groups to the corresponding image sensor according to the photographing instruction, so as to obtain the N groups of image information.

Exemplarily, in the embodiment of the present invention, when N is equal to 4, that is, when the terminal is as shown in fig. 4, four groups of lens groups are provided, since the upper left lens group 1, the upper right lens group 2, the lower left lens group 3, and the lower right lens group 4 are all convex lens groups, light is converged according to the convex lens imaging principle. The light of the upper left part of the terminal passes through the refraction of the upper left lens group 1, can obtain corresponding formation of image, project corresponding image sensor, obtain first group image information promptly, and is the same, the light of the upper right part of the terminal passes through the refraction of the upper right lens group 2, can obtain corresponding formation of image, project corresponding image sensor, obtain second group image information promptly, the light of the lower left part of the terminal passes through the refraction of the lower left lens group 3, can obtain corresponding formation of image, project corresponding image sensor, obtain third group image information promptly, the light of the lower right part of the terminal passes through the refraction of the lower right lens group 4, can obtain corresponding formation of image, project corresponding image sensor, obtain fourth group image information promptly. The first group of image information is an image of an object corresponding to the upper left of the front surface of the screen, the second group of image information is an image of an object corresponding to the upper right of the front surface of the screen, the third group of image information is an image of an object corresponding to the lower left of the front surface of the screen, and the fourth group of image information is an image of an object corresponding to the lower right of the front surface of the screen.

It should be noted that, in the embodiment of the present invention, whether the image sensor provided on the terminal is a charge coupled device or a metal oxide semiconductor device is used as a basic means by image capture. The core of the image sensor is a photosensitive diode, the photosensitive diode can generate output current after receiving light irradiation through a lens group, and the intensity of the current corresponds to the intensity of the light irradiation. Further, the image sensor further includes: an amplifier and an analog-to-digital conversion circuit. The output current of the photodiode is too weak to be directly converted by the analog-to-digital conversion circuit, so that the output current is amplified by the amplifier, then the amplified output current is subjected to analog-to-digital conversion by the analog-to-digital conversion circuit, and finally the binary digital image information is output to other related processing chips. That is, the N sets of image information finally obtained by the N image processors in the embodiment of the present invention are actually N sets of binary digital image information.

It can be understood that, in the embodiment of the present invention, the larger the value of N is, the more image information groups obtained by the terminal are, the less the content of each group of image information is, the more accurate it is, and the better the effect of the finally obtained target image is.

And S303, splicing the N groups of image information to obtain a target image.

In the embodiment of the invention, after the terminal obtains the N groups of image information through the N groups of lens groups, the N groups of image information are spliced to obtain the target image.

Specifically, in the embodiment of the present invention, image stitching software may be installed in advance on the terminal, and when the terminal obtains N sets of image information, the image stitching software automatically performs stitching processing on the obtained N sets of image information, so as to obtain the target image.

Fig. 5 is a schematic diagram of an exemplary image mosaic effect provided by an embodiment of the present invention. As shown in fig. 5, an image 1 is obtained by the upper left lens group 1 in fig. 4, an image 2 is obtained by the upper right lens group 2 in fig. 4, an image 3 is obtained by the lower left lens group 3 in fig. 4, and an image 4 is obtained by the lower right lens group 4 in fig. 4. And the terminal splices the image 1, the image 2, the image 3 and the image 4 through image splicing software to obtain a target image 5.

It should be noted that, in the embodiment of the present invention, a user may set image matching software on a terminal according to the needs of the user, the image matching software may further have an image processing function, and when the image matching software matches N sets of image information, some image processing or optimization may also be performed, so as to obtain a target image with better quality. The embodiment of the present invention is not limited to the specific image stitching software.

It can be understood that, in the embodiment of the present invention, the user may also preset the image processing mode required by the user in the image mosaic software. Such as denoising, white balancing, sharpening, etc. And finally obtaining a target image meeting the requirements of the user.

It should be noted that the specific preset image processing method is not limited in the embodiments of the present invention.

Fig. 7 is a third schematic flowchart of a photographing method according to an embodiment of the present invention. As shown in fig. 7, after step S303, the photographing method according to the embodiment of the present invention further includes steps S305 to S308. The method comprises the following specific steps:

s305, receiving a saving instruction.

In the embodiment of the invention, after the terminal obtains the target image, the user can select and store the target image according to the effect of the target image.

Specifically, in the embodiment of the present invention, when the user determines that the target image needs to be saved, a saving instruction is sent to the terminal, and the terminal receives the saving instruction and executes a corresponding response.

S306, storing the target image to a preset storage position according to a preset image format according to the storage instruction.

In the embodiment of the invention, after receiving the storage instruction, the terminal stores the target image to the preset storage position according to the preset image format according to the storage instruction.

It should be noted that, in the embodiment of the present invention, the user may preset an image format and a storage location on the terminal according to the user's own needs. The specific preset image format and the preset storage location are not limited in the embodiments of the present invention.

It can be understood that, in the embodiment of the present invention, after the terminal receives the saving instruction, it needs to first determine whether the current format of the target image is the same as the preset image format. And if the current format of the target image is the same as the preset image format, the terminal directly stores the target image to a preset storage position in the current format. If the current format of the target image is different from the preset image format, the terminal converts the current format of the target image into the preset image format and then stores the target image converted into the preset image format in a preset storage position.

Illustratively, the preset image format on the terminal is Joint Photographic Experts Group (JPEG) format, and the preset storage location is a memory card. After the terminal receives the storage instruction, it needs to first determine whether the current format of the target image is the JPEG format. If the current format of the target image is JPEG format, the terminal directly saves the target image to the memory card in JPEG format. If the current Format of the target Image is a Tag Image File Format (TIFF), the terminal converts the target Image from TIFF to JPEG Format through Image Format conversion software, and then stores the target Image converted to JPEG Format in a memory card.

It should be noted that, when the terminal stores the target image in the preset storage location according to the preset image format, the terminal may also appropriately compress the target image and then store the target image, so as to save the space of the preset storage location.

It can be understood that, if the storage location is not preset on the terminal, the terminal may also autonomously read the storage locations of each internal portion, and store the target image to the storage location with the largest remaining storage space according to the preset image format, or search the storage location with the largest number of images stored according to the preset image format, and store the target image at the location, which is convenient for the user to quickly search and call.

For example, if the storage location is not preset on the terminal, the terminal autonomously reads the internal storage location of each part. If two storage positions exist on the terminal, the two storage positions are respectively as follows: memory cards and local storage. And when the terminal reads that the residual storage space of the memory card is smaller than the residual storage space of the local storage, the target image is stored in the memory card according to the preset image format. Or searching the storage position with the most images stored according to the preset image format, storing the target image to the storage card according to the preset image format when the terminal reads that the number of the images stored in the storage card according to the preset image format is more than that of the images stored in the local storage according to the preset image format, and storing the target image to the local storage according to the preset image format when the terminal reads that the number of the images stored in the storage card according to the preset image format is less than that of the images stored in the local storage according to the preset image format.

S307, receiving a deleting instruction.

In the embodiment of the invention, after the terminal saves the target image, the user can select to delete the target image according to the effect of the target image.

Specifically, in the embodiment of the present invention, when the user determines that the target image needs to be deleted, a deletion instruction is sent to the terminal, and the terminal receives the deletion instruction and executes a corresponding response.

And S308, deleting the target image according to the deleting instruction.

In the embodiment of the invention, after the terminal receives the deleting instruction, the target image is deleted according to the deleting instruction.

Specifically, in the embodiment of the present invention, if the target image is displayed on the screen, the user may directly press the target image on the screen for a long time, and the option list corresponding to the target image is displayed on the screen, and the target image is selected to be deleted. If the target image is not displayed on the screen, the user can open a preset storage position of the target image, open an option list corresponding to the target image in the preset storage position of the target image, and select deletion in the option list, namely, the terminal receives a deletion instruction and deletes the stored target image.
