Description

Mobile terminal and photo processing method thereof

Technical Field

The invention relates to the field of mobile terminals, in particular to a mobile terminal and a photo processing method thereof.

Background

With the development of science and technology, mobile terminals gradually develop towards the direction of full-screen. The full screen is a broader definition of ultra-high screen than the design of the mobile phone in the mobile phone industry. The explanation is that the front of the mobile phone is a screen, and the four frame positions of the mobile phone are designed without frames, so that the screen occupation ratio is close to 100%. However, due to the limitation of the current technology, the mobile phone with a full screen declared in the industry is only a mobile phone with an ultra-high screen ratio temporarily, and a mobile phone with a front screen ratio of 100% cannot be realized. The comprehensive screen mobile phone in the industry refers to a mobile phone with an ultra-narrow frame design, wherein the real screen proportion can reach more than 80%. The full-screen mobile phone faces various design and manufacturing difficulties, such as the positions of a receiver and a front camera, and how to solve the problem of front fingerprint identification.

At present, in the prior art, mobile phone manufacturers generally adopt an ultra-narrow frame or change the layout of a camera to improve the screen occupation ratio of the mobile phone. The design of the ultra-narrow frame is limited by the processing technology and the processing assembly, and further narrowing is difficult. Changing the layout of the cameras is typically accomplished by digging a hole screen, lifting cameras, and flipping cameras. Dig the hole screen and pass through the trompil on the display screen of cell-phone to install the leading camera of cell-phone in above-mentioned trompil, in order to reduce leading camera and relevant subassembly and occupy the space of screen top, dig hole screen formula design because the camera is installed in the screen below, the daylighting of camera receives the influence, influences the imaging quality of camera to a certain extent. The lifting camera and the turnover camera can move from the inside of the mobile phone to the outside of the mobile phone only by means of the driving mechanism, but the thickness of the mobile phone is increased by arranging the driving mechanism.

Some mobile phones have a front camera disposed on the inner side of the display screen, but the layers of the screen are stacked to form refraction of the screen in the layers of the material and opacity of RGB (red, green, and blue) light-emitting points displayed on the screen, so that aperture diffraction or barrier diffraction is formed. Under the condition that the light source is relatively strong or the light source part is relatively large, more effective display areas are covered by the diffraction light source due to diffraction shielding of the shot picture, and shot samples are seriously distorted, so that the shooting experience of a user is influenced.

Therefore, the prior art has defects and needs to be improved and developed.

Since the distribution of the transparent part of the second functional region corresponds to the distribution of the RGB light emitting diodes of the first functional region, and the black area of the second functional region except the transparent part corresponds to the transparent part of the first functional region, the sum of the complex amplitudes of the light fields generated by the two complementary screens at a certain point of the diffraction field alone is equal to no screen according to the babinet principle.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The invention provides a mobile terminal, which is also called a mobile communication terminal and refers to a computer device capable of being used in moving, and the mobile terminal broadly comprises a mobile phone, a notebook, a tablet computer and even a vehicle-mounted computer. But most often refer to cell phones or smart phones and tablets with multiple application functions. With the development of networks and technologies toward wider and wider bands, the mobile communication industry will move to the real mobile information age, and therefore, the functions of mobile terminals are also more and more powerful. The mobile terminal can not only communicate, take pictures, listen to music and play games, but also realize rich functions such as positioning, information processing, fingerprint scanning, identity card scanning, bar code scanning and the like, and becomes an important tool for mobile law enforcement, mobile office and mobile commerce.

Referring to fig. 1, as an embodiment of the present disclosure, a mobile terminal 100 includes a front camera module 1 for self-photographing, and an Organic Light-Emitting display (OLED) screen 2 disposed outside the front camera module 1.

The front camera is developed by mobile phone manufacturers to meet the video call requirements of the masses, and can shoot users positioned in front of a screen. The specific structure of the front camera can refer to the related art, and is not described in detail herein.

In the prior art, a mobile terminal is designed to improve the screen ratio, but a bang screen or a hole digging screen is usually adopted because a front-facing camera needs to be arranged. Bang screen means reserves out certain space on the top of mobile terminal's screen and is used for installing leading camera, and this reservation space consequently can not be used for showing owing to install leading camera. Therefore, the design of the bang screen causes the screen of the mobile terminal to lack a part of display area, and the full screen cannot be realized. The hole digging screen is characterized in that a front camera is arranged on the inner side of a screen, and holes are formed in the position, corresponding to the front camera, of the screen so as to reduce lighting of the screen on the front camera. In this application, leading module 1 of making a video recording sets up OLED screen 2's inboard is followed promptly mobile terminal 100's thickness direction, leading module 1 of making a video recording is located OLED screen 2's below, consequently, leading module 1 of making a video recording does not occupy OLED screen 2's display area for whole OLED screen 2 all can be used to show, can realize the full face screen.

The front camera module 1 includes at least two cameras 11, in this embodiment, the front camera module 1 is provided with two cameras 11, and the two cameras 11 are arranged along the width direction interval of the mobile terminal 100. However, the number of cameras 11 included in the front camera module 1 is not limited to two. The distribution among the cameras 11 of the front camera module 1 is not limited to be spaced along the width direction of the mobile terminal 100, for example, the cameras 11 of the front camera module 1 may be spaced along the length direction of the mobile terminal 100 or irregularly distributed at the rear side of the OLED screen 2.

Referring to fig. 2, the OLED screen is used for displaying images, and OLED is a new display technology, which has many advantages of ultra-thin, full solid state, active light emission, fast response speed, high contrast, no view angle limitation, wide operating temperature range, low power consumption, low cost, strong shock resistance, and flexible display, and is known as a "illusion display device". The OLED screen 2 is substantially rectangular. The OLED screen 2 is located on the outer side of the front camera module 1, namely the OLED screen 2 covers the outer side of the front camera module 1. The OLED screen 2 comprises a bearing film 21 used for installing RGB light-emitting diodes 22, wherein the bearing film 21 is formed by coating a super-transparent polyester film (PET) with special silica gel, then attaching a PET release film, and then attaching a PET protective film on a hardening treatment surface. The fixing technique of the RGB leds 22 on the carrier film 21 can refer to the related art, and is not described in detail herein. The RGB leds 22 enable the OLED screen 2 to display colors, and the OLED screen 2 can display a preset pattern by controlling the light emitting colors of the RGB leds 22.

Referring to fig. 3 and fig. 4, a first functional region 211 and a second functional region 212 are respectively disposed on the carrier film 21 corresponding to the two cameras 11, that is, the first functional region 211 and the second functional region 212 are respectively disposed outside the two cameras 11 and are respectively opposite to the two cameras 11. The areas of the carrier film 21 except the first functional area 211 and the areas except the second functional area 212 are both provided with RGB light emitting diodes 22, that is, the areas except the first functional area 211 and the areas except the second functional area 212 on the OLED screen 2 can both be used for displaying images. The first functional area 211 is transparent, so that light can penetrate through the first functional area 211 and enter the camera 11 behind the first functional area 211, which is convenient for the camera 11 to capture light. The RGB leds 22 are disposed on the first functional region 211, so that the first functional region 211 can be used for displaying images, i.e., the first functional region 211 is also a display region. The size of the first functional area 211 is adapted to the size of the camera 11 corresponding to the first functional area, so that the camera 11 corresponding to the first functional area is not blocked by an area outside the first functional area 211.

The second functional region 212 is disposed corresponding to the first functional region 211. The second functional region 212 appears black overall. The position of the second functional region 212 corresponding to the position of the first functional region 211 where the RGB light emitting diodes 22 are disposed is a transparent portion 2121, and the transparent portion 2121 is in a transparent state, that is, if the first functional region 211 is overlapped with the second functional region 212, the RGB light emitting diodes 22 disposed on the first functional region 211 are completely overlapped with the transparent portion 2121 on the second functional region 212, and the size and shape of the transparent portion 2121 are completely the same as the size and shape of the transparent portion 2121. The area of the second functional region 212 except for the transparent portion 2121 is black, and the RGB leds 22 are disposed in the black area, so that the second functional region 212 can also be used for displaying, that is, the second functional region 212 is also a display area. Since both the first functional region 211 and the second functional region 212 can be used for displaying, both the OLED screen 2 can be used for displaying, i.e., the OLED screen 2 realizes a full screen.

Since the RGB leds 22 of the first functional region 211 block the rear camera 11 to a certain extent, diffracted light waves are not generated except for the position where the RGB leds 22 are disposed. For the second functional region 212, the diffracted light waves do not generate a diffraction stop except in the transparent portion 2121. Since the distribution of the transparent portion 2121 of the second functional region 212 corresponds to the distribution of the RGB leds 22 of the first functional region 211, and the black area of the second functional region 212 except the transparent portion 2121 corresponds to the transparent portion of the first functional region 211, the sum of the complex amplitudes of the light fields generated by the two complementary screens at a certain point of the diffraction field is equal to that without any screen according to the babinet principle. According to the Volvier-Fisher theorem, the two diffracted light intensity distributions are the same, the energy except the central point is added to be 0, namely the two diffracted spots are complementary and are in a screenless state after being accumulated, so that when a picture is taken, the diffracted light waves generated at RGB positions of the picture taken by the camera 11 corresponding to the first functional area 211 are removed, the diffracted light waves generated at a black area of the picture taken by the camera 11 corresponding to the second functional area 212 are removed, namely, only the image corresponding to the transparent part 2121 is left, and the two pictures are fused, so that the picture without diffraction and without loss of a light source accessory can be obtained, therefore, the problem that the picture taken by the camera 11 arranged under the screen is seriously distorted due to screen shielding is solved while the invention is used for completely screening.

The OLED screen 2 further has a screen splitting function, and when the mobile terminal 100 is used for taking a picture, the RGB light emitting diodes 22 of the first functional area 211 and the RGB light emitting diodes 22 of the second functional area 212 on the OLED screen 2 do not emit light, so that interference of light emitted by the RGB light emitting diodes 22 on lighting of the camera 11 is avoided. The principle of the split screen function of the OLED screen 2 can be referred to the related art, and is not described in detail herein. In some embodiments, the first functional region 211 and the second functional region 212 are disposed along the width direction of the OLED screen 2, so that the area of the OLED screen 2 corresponding to the diameter width of the first functional region 211 and the second functional region 212 is in a screen-rest state when the front camera module 1 takes a picture. For example, when the diameters of the first functional area 211 and the second functional area 212 are 3 mm, when the front camera module 1 of the mobile terminal 100 takes a picture, a screen-turning area with a width of 3 mm is located on the OLED screen 2 corresponding to the front camera module 1, and an area below the screen-turning area is in a screen-on state and is used as a picture preview area of the front camera module 1.

Specifically, as an implementation manner of this embodiment, please refer to fig. 3, in which the driving circuit 5 of the RGB leds 22 located in the first functional area 211 is in a transparent state. The RGB leds 22 need to be wired to emit light after being powered on. Since the driving circuit 5 of the RGB led 22 is transparent, there is no other object in the first functional area 211 except the RGB led 22, which causes the camera 11 disposed inside the first functional area 211 to generate a diffraction aperture, so that the camera 11 located inside the first functional area 211 only generates a diffraction aperture at a position corresponding to the RGB led 22.

Specifically, as an implementation manner of this embodiment, referring to fig. 3, the material of the driving circuit 5 in the first functional region 211 is an ITO (Indium Tin Oxide) material. Since the ITO material is conductive and transparent, the ITO material is used as the driving lines 5 of the RGB leds 22, which can prevent the driving lines 5 of the RGB leds 22 from generating diffraction apertures and diffracting the camera 11 disposed behind the first functional region 211.

Specifically, referring to fig. 3, as an implementation manner of the present embodiment, the RGB light emitting diodes 22 of the first functional region 211 include an R unit 221 for emitting red light, a G unit 222 for emitting green light, and a B unit 223 for emitting blue light. The R cell 221, the G cell 222, and the B cell 223 in combination may generate different colors, for example, when the R cell 221 and the G cell 222 belonging to the same RGB light emitting diode 22 are simultaneously bright and the B cell 223 is not bright, the RGB light emitting diode 22 displays yellow. When the G cell 222 and the G cell 222 belonging to the same RGB light emitting diode 22 are simultaneously bright and the R cell 221 is not bright, the RGB light emitting diode 22 displays cyan. The first functional region 211 is provided with a plurality of RGB leds 22, the plurality of RGB leds 22 are arranged in a plurality of rows, and the plurality of rows of RGB leds 22 are arranged in a staggered manner and at intervals by using a first arrangement manner and a second arrangement manner. The first arrangement is such that the R cells 221 and the G cells 222 are alternately arranged. The second arrangement is such that a plurality of the B cells 223 are arranged at intervals. In a specific embodiment, the resolution of the first functional region 211 using the above arrangement is 400PPI (pixel density).

Specifically, referring to fig. 3, as an implementation manner of the present embodiment, the B unit 223 of the first functional region 211 is longitudinally located between the corresponding R unit 221 and the corresponding G unit 222, so that the first functional region 211 has a higher pixel density.

Specifically, referring to fig. 4 in combination with fig. 3, as an implementation manner of this embodiment, a plurality of transparent portions 2121 of the second functional region 212 are provided, and the plurality of transparent portions 2121 are arranged in multiple rows at intervals and are in one-to-one correspondence with the RGB light emitting diodes 22 arranged on the first functional region 211, that is, if the first functional region 211 is overlapped with the second functional region 212, the RGB light emitting diodes 22 on the first functional region 211 are overlapped with the transparent portions 2121 on the second functional region 212. The RGB leds 22 of the second functional region 212 are provided with a plurality of rows, and the plurality of rows of RGB leds 22 of the second functional region 212 are alternately spaced from the plurality of rows of transparent portions 2121, for example, the odd rows of the second functional region 212 are transparent portions 2121, and the even rows of the second functional region 212 are used for providing the RGB leds 22.

Specifically, referring to fig. 4, as an implementation manner of the present embodiment, the RGB leds 22 of the second functional region 212 include an R unit 221 for emitting red light, a G unit 222 for emitting green light, and a B unit 223 for emitting blue light. The RGB leds 22 in the second functional region 212 have a plurality of rows, and the plurality of rows of RGB leds 22 are alternately arranged in a third arrangement manner and a fourth arrangement manner. The third arrangement is that the R cells 221 and the G cells 222 are alternately arranged. The fourth arrangement is such that a plurality of the B cells 223 are arranged at intervals. When odd rows are used to provide the RGB light emitting diodes 22, for example, when the R cells 221 and the G cells 222 of the RGB light emitting diodes 22 are arranged in the third arrangement in the first row, the second row is used to arrange the transparent portions 2121, and the third row is used to arrange the B cells 223 of the RGB light emitting diodes 22 in the fourth arrangement. In a specific embodiment, the resolution of the first functional region 211 using the above arrangement is 400 PPI.

Specifically, referring to fig. 4, as an implementation manner of the present embodiment, the B unit 223 of the second functional region 212 is longitudinally located between the corresponding R unit 221 and the corresponding G unit 222, so that the first functional region 211 has a higher pixel density.

Specifically, referring to fig. 1 as an implementation manner of this embodiment, the mobile terminal 100 further includes a rear housing 3, the rear housing 3 is substantially groove-shaped, the rear housing 3 is located at a rear side of the front camera 11, and the rear housing 3 is connected to the OLED screen 2 in a covering manner to seal the front camera module 1 located at an inner side of the OLED screen 2. The OLED screen 2 and the rear cover can be connected by glue through point gluing on the contact surface of the OLED screen 2 and the rear cover under the bonding of glue.

The mobile terminal 100 is further provided with a rear camera (not shown), the rear camera is arranged between the OLED screen 2 and the rear shell 3, the rear shell 3 is arranged right opposite to the rear shell 3 and used for shooting objects behind the mobile terminal 100, correspondingly, a through hole is formed in the position, corresponding to the rear camera, of the rear shell 3, and therefore the rear shell 3 is prevented from shielding lighting of the rear camera.

When the front camera module 1 of the mobile terminal 100 is provided with a plurality of cameras 11, the OLED screen 2 is correspondingly provided with a plurality of first functional areas 211 and a plurality of second functional areas 212. For example, when the front camera module 1 is provided with four cameras 11, two first functional regions 211 and two second functional regions 212 may be disposed on the OLED screen 2. The two first functional regions 211 and the two second functional regions 212 are arranged at intervals, and illustratively, the first functional region 211, the second functional region 212, the first functional region 211, and the second functional region 212 are sequentially arranged along the width direction of the screen. When shooting is completed, the mobile terminal 100 selects a picture with better imaging quality from the cameras 11 corresponding to the two first functional areas 211 for fusion processing, and correspondingly, the mobile terminal 100 selects a picture with better imaging quality from the cameras 11 corresponding to the two second functional areas 212 for fusion processing, so as to obtain a picture with higher imaging quality.

In summary, the present invention provides a mobile terminal 100, wherein the first functional area 211 and the second functional area 212 of the mobile terminal 100 are both provided with RGB light emitting diodes 22, so that both the first functional area 211 and the second functional area 212 can be used for displaying images, and the OLED screen 2 can realize a full-screen. Since the RGB leds 22 of the first functional region 211 block the rear camera 11 to a certain extent, diffracted light waves are not generated except for the position where the RGB leds 22 are disposed. For the second functional region 212, the diffracted light waves do not generate a diffraction stop except in the transparent portion 2121. Since the distribution of the transparent portion 2121 of the second functional region 212 corresponds to the distribution of the RGB leds 22 of the first functional region 211, and the black area of the second functional region 212 except the transparent portion 2121 corresponds to the transparent portion of the first functional region 211, the sum of the complex amplitudes of the light fields generated by the two complementary screens at a certain point of the diffraction field is equal to that without any screen according to the babinet principle. According to the Volvier-Fisher theorem, the two diffracted light intensity distributions are the same, the energy except the central point is added to be 0, namely the two diffracted spots are complementary and are in a screenless state after being accumulated, so that when a picture is taken, the diffracted light waves generated at RGB positions of the picture taken by the camera 11 corresponding to the first functional area 211 are removed, the diffraction generated at a black area of the picture taken by the camera 11 corresponding to the first functional area 211 is removed, the two pictures are fused, and the picture without diffraction and without loss of a light source accessory can be obtained, therefore, the problem that the picture taken by the front camera 11 under the screen is seriously distorted due to screen shielding is solved while the screen is comprehensive.

The present invention further provides a photo processing method for processing the photo taken by the mobile terminal 100, wherein the photo processing method comprises the following steps:

step A: acquiring pictures shot by a front camera module of the mobile terminal, and judging whether the pictures respectively shot by the two cameras have diffraction generated by a far-field light source; if the pictures shot by the two cameras have no diffraction generated by a far-field light source, directly outputting the picture shot by one of the cameras; if diffraction generated by a far-field light source exists in the picture shot by at least one camera, entering step B;

and B: respectively acquiring two pictures shot by the two cameras; and extracting a light source diffraction part of the photo with diffraction generated by a far-field light source, extracting a light source part without diffraction in the other photo, fusing the two extracted parts, and outputting the photo after the fusion processing.

The non-diffraction parts in the pictures shot by the two cameras can be fused through the fusion processing, and the pictures shot by the two cameras are complementary, so that a picture without diffraction can be obtained after the fusion processing.

In summary, the present invention further provides a method for processing the photos taken by the front camera module 1 of the mobile terminal 100, and the two photos taken by the front camera module 1 are fused to output the photos with high imaging quality, so as to solve the problem that the photos taken by the front camera 11 under the screen are seriously distorted due to the screen shielding.
