Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides electronic equipment aiming at the problem that the appearance of the electronic equipment is reduced due to the fact that a display screen or a backlight area is hollowed out in the existing comprehensive screen design scheme of a water drop screen, and black dots hollowed out by a camera can be seen from the front side of the electronic equipment.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides an electronic device, including:
a display screen 100;
the at least two cameras 200 are arranged on a first side of the display screen 100, and the first side is a side away from a glass cover plate of the electronic device;
the pixel density of the first area 110 on the display screen 100 is lower than the pixel density of the second area 120 on the display screen 100, the first area 110 is an area facing the field of view (FOV) of the at least two cameras 200, and the second area 120 is an area other than the first area 110 on the display screen 100.
It should be noted that, in order not to affect the display of the display screen, the camera should be disposed below the display screen, and in order to further enhance the light transmittance of the display screen in the area corresponding to the camera, the pixel density of the area of the display screen corresponding to the field angle of the camera 200 should be set to be smaller than the pixel density of other areas of the display screen, alternatively, the above-mentioned first area may be a connected area, that is, when there is a partial overlap in the field angles of different cameras, the finally determined first area is a continuous area on the display screen; alternatively, the first area may be a plurality of unconnected areas, that is, when there is no overlap of the angles of view of different cameras, that is, the angles of view of at least two cameras do not overlap, in this case, the corresponding areas of the cameras whose angles of view do not overlap on the display screen are not connected together, and in this case, the first area is at least two scattered areas.
It should be noted that the at least two cameras are arranged in an array, for example, a 2 × 1 array, a 2 × 2 array, etc., that is, the at least two cameras may also be referred to as an array camera.
As shown in fig. 5 and 6, the at least two cameras (taking a 2 × 1 array as an example) respectively include: the light-gathering lens 210, the lens mount 220, the optical filter 230 and the light-sensing chip 240, and at least two cameras share the same connector 250 and the same Flexible Printed Circuit (FPC)260, so that the space of the whole machine can be saved.
It should be noted that the display screen is composed of three primary colors RBG of a certain pixel, and the pixel density is calculated by PPI. PPI, the number of pixels per inch (pixels per inch), represents the number of pixels per inch diagonal. The calculation method comprises the following steps: the PPI is obtained by calculating the number of pixels in the diagonal direction (right triangle) by the number of pixels with a high pitch and then dividing the number of pixels in the diagonal direction by the size of the screen, and the formula is expressed as
Wherein X represents the number of pixels in length; y represents the number of width pixels; z represents a screen size.
The Pentile arrangement is an arrangement mode of common OLED display RGB sub-pixels at present, the traditional arrangement has equal three-primary-color light-emitting areas, and the Pentile has unequal RGB light-emitting areas. FIG. 7 is a diagram of RGB pixels of an OLED screen, where red represents R, green represents G, and blue represents B; one pixel point of RGB Pentile can form three primary colors by using another color of the pixel point adjacent to the pixel point, and each pixel and the adjacent pixels share a sub-pixel of the color which is not possessed by the pixel in the horizontal direction, so that white display is achieved together. It should be noted that, pixels and metal wires inside the OLED screen can cause large attenuation to transmittance, and micron-sized holes (white portions in fig. 7 are light-permeable areas) between the metal wires (light-impermeable) can cause strong diffraction, which affects the definition of photographed images.
Thus dividing the screen into two regions, as shown in fig. 8, i.e., an in-field-of-view region of the camera, i.e., a first region (also referred to as a low PPI region 416) and an out-of-field-of-view region, i.e., a second region (also referred to as a high PPI region 417), the low PPI region 416 having a pixel density of 100 to 200 pixels/inch (i.e., the first region has a pixel density of 100 to 200 pixels/inch as described above); taking 100PPI as an example, taking 8 pixels as a group, 6 pixels are removed from 8 pixels, 2/8 remains, and the remaining RGBG of each row as 413 can still be synthesized to display white, the manner of removing pixels is shown in fig. 9 and 10, and the low PPI region 416 is arrayed in this way. If the high PPI region 417 is 400, the local area is 100PPI, the number of micron-sized holes of the trace 414 is reduced in the local area, and the area of the light-permeable region (relative to the PPI 400 region) is increased, as shown in fig. 9 and fig. 10, the white region 415 can greatly reduce the diffraction effect and increase the overall transmittance (the light-permeable region is greatly increased, the holes are reduced), thereby improving the photographing effect.
As further shown in fig. 11, the low PPI region 416 includes at least one pixel unit 418, the high PPI region 417 includes a plurality of pixel units 419 (i.e., the first region includes at least one pixel unit, and the second region includes at least two pixel units), and the pixel area of at least one of the three sub-pixels R, G, B of the low PPI region 416 is larger than the pixel area of any one of the three sub-pixels R, G, B of the high PPI region 417 (i.e., the area of the pixel unit of the first region is larger than the area of the pixel unit of the second region), so that the area occupied by the lines, components and the like arranged in the low PPI region 416 can be reduced, and the light transmittance of the lines, components and the like arranged in the low PPI region 416 is poor, so that the area ratio of the high light transmittance region can be increased, the light transmittance of the low PPI region 416 is further increased, and thus the transmittance of the array camera can be further improved. The low PPI region 416 may be sized according to the size of the lens of the array camera.
The lens of the array camera is in the plane of the low PPI area 416, when the camera is turned on, 4 cameras respectively shoot 4 initial photos with 1 initial photo, and effective pixels of the 4 initial photos are synthesized through a software algorithm, so that a clear and complete photo can be obtained. It should be noted that when the array camera performs the first shooting, the pixel unit or the sub-pixel where the low PPI region 416 is turned on may block part of the light, and a target photo that is not interfered by the working pixels in the low PPI region 416 may be obtained by synthesizing a plurality of photos through the array, so that the transmittance is significantly improved, and the shooting quality is improved.
Optionally, the at least two cameras satisfy at least one of:
a11, the number of pixels corresponding to at least one camera in the at least two cameras is different from that of the other cameras;
that is, the array camera can have different numbers of pixels, for example, four cameras, for example, camera 1 is used as the main camera, the number of pixels is 1300 ten thousand, and cameras 2 to 4 can reduce the number of pixels, for example, 200 ten thousand, because these three cameras are only used for image synthesis to improve the brightness.
A12, the area of a pixel corresponding to at least one camera in the at least two cameras is different from that of other cameras;
that is to say, array camera can have different pixel sizes to four cameras are for example, and as main camera, pixel size is 0.8um like camera 1, and camera 2 ~ 4 can be with big pixel, like 1.0um or 1.2um, improve luminance better.
It should be noted that each photosensitive chip region of the array camera in the embodiment of the present invention has an independent lens, and can perform imaging independently, the combination of each group of photosensitive chips and the condensing lens can ensure the accuracy of local camera acquisition, and each imaging block can implement image stitching through a software algorithm, so as to improve the brightness of the whole camera acquisition.
According to the embodiment of the invention, the camera is arranged below the display screen, and the pixel density of the area corresponding to the field angle of the camera on the display screen is set to be smaller than that of other areas, so that the image acquisition can be realized without arranging a camera light hole on the display screen, and the attractiveness of the electronic equipment is improved.
The electronic device according to the embodiment of the present invention may be a mobile terminal such as a mobile phone, a portable device such as a PAD, a notebook computer, or the like.
As shown in fig. 12, an embodiment of the present invention further provides a photographing method, where the electronic device includes:
step 1201, acquiring a shot image of each camera of the at least two cameras;
Specifically, the specific implementation manner of step 1202 is: and superposing the brightness of the images according to the pixels to obtain a photographed image, namely superposing the brightness of the pixels at the same position in different images, and obtaining the photographed image after finishing the superposition of the pixels at all positions.
It should be noted that, by synthesizing the images shot by the cameras, a shot image is finally obtained, and this way can improve the brightness of the whole camera and the quality of image acquisition.
