It can be understood that mobile The specific form of the terminal 100 is not limited to a mobile phone.

The housing 10 may be a housing composed of a middle frame, a front case, a rear cover, and the like of the mobile terminal 100. The housing 10 can be used as a mounting carrier for functional devices of the mobile terminal 100. For example, the housing 10 can be used as a mounting carrier for the display device 20, the movable member 30, the power supply device, etc., so that the structure of the mobile terminal 100 is relatively compact.

The display device 20 can be used to display information such as images, text, and video for the user to view, and the user can also perform touch operations on the display device 20 to input instructions to the mobile terminal 100. The display device 20 may specifically be an organic self-luminous display, a liquid crystal display, a micro LED display, or the like.

The display device 20 is installed on the housing 10. Specifically, the display device 20 may be installed on the front of the housing 10 as a front display device, or the display device 20 may be installed on the back of the housing 10 as a rear display device, or the display device 20 may be installed on the housing 10. The side surface of is used as a side display device, or the display device 20 includes both a front display device and a rear display device, or the display device 20 can switch between the front display device and the rear display device, etc., which is not limited here.

At this time, the movable The member 30 can be rotated relative to the casing 10 to switch to the state shown in FIG. 1 b, and the movable member 30 is hidden in the casing 10. Of course, when the movable element 30 and the housing 10 are in the state shown in FIG. 1b, the movable element 30 can be rotated relative to the housing 10 to switch to the state shown in FIG. 1a.

In the example shown in Figs. 2a and 2b, the movable element 30 can move relative to the housing 10. In the state shown in Fig. 2a, the movable element 30 is exposed from the housing 10. At this time, the movable The member 30 can move relative to the housing 10 to switch to the state shown in FIG. 2b, and the movable member 30 is hidden in the housing 10.

The number of imaging devices 32 mounted on the bracket 31 may be one or multiple, for example, it may be two, three, etc., which is not limited here.

With the relative movement between the bracket 31 and the casing 10, the bracket 31 can drive the imaging device 32 to move to change the positional relationship between the imaging device 32 and the casing 10 and the display device 20. In the state shown in FIGS. 1a and 2a, the imaging device 32 is exposed from the housing 10. In the state shown in FIGS. 1b and 2b, the imaging device 32 is located in the housing 10, while the imaging device 32 is located in the display device. 20 below.

Referring to FIGS. 3a and 3b, the imaging device 32 includes a lens group 321 and an image sensor 322. When the imaging device 32 performs imaging, light passes through the lens group 321 and then reaches the image sensor 322.

The lens group 321 may be an optical component composed of at least one lens, and the lens may be a concave lens or a convex lens. After the light passes through the lens group 321, it can be focused on the image sensor 322 so that the image sensor 322 can generate a clear image.

The image sensor 322 is used to convert the light signal irradiated to the image sensor 322 into an electrical signal, so that the signal value of the electrical signal can be subsequently used to obtain an image through image processing.

The photosensitive unit can be converted into an electrical signal according to the light signal of a specific color irradiated on the photosensitive unit, and the strength of the electrical signal can reflect the strength of the light signal of the specific color. For example, in Figure 4, the R photosensitive unit represents the red photosensitive unit, which can be converted into electrical signals according to the red light in the light, the G photosensitive unit represents the green photosensitive unit, which can be converted into electrical signals according to the green light in the light, and the B photosensitive unit represents the blue light. The color photosensitive unit means that it can be converted into electrical signals according to the blue light in the light. Of course, there can also be other types of photosensitive units to convert other types of light into electrical signals, which is not limited here. For example, the W light-sensing unit in FIG. 5 represents a full-color light-sensing unit, which can be converted into an electric signal according to the light in the visible light waveband in the light.

The photosensitive unit array 50 includes a plurality of minimum repeating units 51, and the photosensitive unit array 50 can be regarded as a plurality of minimum repeating units 51 arranged in an array. The minimum repeating unit 51 is composed of a plurality of photosensitive units.

For example, in the example shown in FIG. 4, the smallest repeating unit 51 is 2 rows, 2 columns and 4 photosensitive units, and the arrangement of the photosensitive units of the same smallest repeating unit 51 is:

R G

G B

Among them, R represents a red light-sensitive unit, G represents a green light-sensitive unit, and B represents a blue light-sensitive unit. The arrangement of the photosensitive units of the smallest repeating unit 51 shown in FIG. 4 can also be referred to as a Bayer array. The smallest repeating unit 51 arranged in a Bayer array can better simulate the perception characteristics of human eyes to ambient light, so as to obtain better imaging quality.

For example, the smallest repeating unit 51 includes at least one full-color photosensitive unit, for example, one-quarter of the smallest repeating unit 51 may be a full-color photosensitive unit, or one-half of the smallest repeating unit 51 may be a full-color photosensitive unit. The unit is a full-color photosensitive unit, or one-eighth of the photosensitive units in the smallest repeating unit 51 may be a full-color photosensitive unit. Since the spectral effect of the full-color photosensitive unit is wider than that of the monochromatic photosensitive unit (for example, the red photosensitive unit, the green photosensitive unit, and the blue photosensitive unit), the full-color photosensitive unit can obtain stronger light signals under the same light intensity. In this way, the photosensitive unit array 50 can obtain more scene details even in a weak light environment.

For example, in the example shown in FIG. 5, the smallest repeating unit 51 is 2 rows, 2 columns and 4 photosensitive units, and the arrangement of the photosensitive units of the same smallest repeating unit 51 is:

R W

G B

Among them, W represents a full-color light-sensitive unit, R represents a red light-sensitive unit, G represents a green light-sensitive unit, and B represents a blue light-sensitive unit. Of course, the specific arrangement of the smallest repeating unit 51 including the full-color photosensitive unit may also be other, and is not limited to the above examples.

The following will introduce the specific use of the imaging device 32 for imaging:

The imaging device 32 can be in the first imaging mode or the second imaging mode.

In the first imaging mode, the bracket 31 moves to drive the imaging device 32 to be exposed from the housing 10 and perform imaging. Specifically, as shown in FIGS. 1a, 2a, and 3a, the imaging device 32 is exposed from the housing 10, and the imaging device 32 can directly receive external light for imaging. Since in the first imaging mode, the imaging device 32 is not blocked by other components of the mobile terminal 100, the imaging device 32 can receive more light in the first imaging mode, and the image formed in the first imaging mode is The quality is high and can meet the user's requirements for high-quality imaging.

In the second imaging mode, the imaging device 32 is located in the housing 10, and the imaging device 32 receives light passing through the display device 20 for imaging. Specifically, as shown in FIG. 1b, FIG. 2b, and FIG. 3b, the imaging device 32 is located in the housing 10. The imaging device 32 receives light passing through the display device 20 for imaging, and there is no need to control the movable member 30 to move first. Exposing the imaging device 32 from the housing 10 facilitates the imaging device 32 to quickly obtain an image of the scene and reduces the waiting time of the user. For example, when the user needs to perform face recognition to unlock the mobile terminal 100, the user does not need to wait for the imaging device 32 to be exposed from the housing 10, but can perform imaging and face recognition through the second imaging mode, reducing the user’s waiting time. Time to improve user experience.

In the related prior art, when the imaging device needs imaging, the imaging device must be exposed from the housing, and driving the imaging device to be exposed from the housing must take a certain time, and the user needs to wait for the imaging device to be exposed from the housing. Shooting later reduces the user experience.

In the mobile terminal 100 of the embodiment of the present application, the imaging device 32 can perform imaging when exposed from the housing 10 (that is, imaging in the first imaging mode), and the imaging device 32 can also receive through the display device when in the housing 10 The light of 20 is used for imaging (that is, imaging in the second imaging mode), which enriches the applicable scenarios of the imaging device 32 and improves the user experience of using the imaging device 32 for imaging.

The image acquisition method of the embodiment of the present application can be applied to the mobile terminal 100 of any embodiment of the present application. Referring to FIG. 6, the image acquisition method includes the steps:

01: According to the first instruction, control the movement of the bracket 31 to drive the imaging device 32 to be exposed from the housing 10, and control the imaging device 32 to perform imaging; and

02: According to the second instruction, control the imaging device 32 to receive light passing through the display device 20 to perform imaging.

The first instruction may be an instruction input by the user to enter the first imaging mode. For example, the first instruction may be an instruction such as a selfie instruction, a video call instruction, and the like.

The second instruction may be an instruction input by the user to enter the second imaging mode. For example, the second instruction may be an identity verification instruction, a light intensity detection instruction, and the like.

For the specific implementation details of step 01 and step 02, please refer to the above description. The description of imaging performed by the imaging device 32 in the first imaging mode and the second imaging mode will not be repeated here.

Please refer to the example shown in FIG. 7, the mobile terminal 100 further includes a distance detecting device 40. The distance detecting device 40 may be installed on the housing 10 or the distance detecting device 40 may be installed on the bracket 31. The distance detecting device 40 is used for detecting whether there is obstruction in the stroke of the imaging device 32 exposed from the housing 10.

If there is an obstruction during the exposing stroke of the imaging device 32 from the housing 10, the imaging device 32 cannot be completely exposed from the housing 10 normally. For example, the imaging device 32 may be all inside the housing 10, or the imaging device 32 may be partly inside the housing 10 and partly outside the housing 10. At this time, the imaging device 32 cannot normally perform imaging in the first imaging mode. If imaging is required, the imaging device 32 can perform imaging in the second imaging mode, so as to avoid damage to the imaging device 32 when the imaging device 32 is exposed from the housing 10. Moving part 30 or driving part.

If there is no obstruction during the exposing stroke of the imaging device 32 from the housing 10, the imaging device 32 can be normally exposed from the housing 10. At this time, the imaging device 32 can normally perform imaging in the first imaging mode, or in the first imaging mode. Two imaging modes for imaging.

For example, the distance detecting device 40 can be installed on the same side of the housing 10 as the movable element 30, and the distance detecting device 40 is used to detect the distance of the obstructing object 200 to determine whether the obstructing object 200 is located in the imaging device 32 from the housing. 10 During the exposed stroke, in other words, it can be judged whether the movable member 30 interferes with the shield 200.

The distance detecting device 40 may specifically be a proximity sensor, a time-of-flight distance measuring device, etc., which is not limited here.

Referring to FIG. 8, in an example, the image acquisition method may further include the steps:

03: Detect whether there is obstruction in the stroke of the imaging device 32 exposed from the housing 10; and

04: When there is an obstruction during the exposing stroke of the imaging device 32 from the housing 10, the imaging device 32 is controlled to receive light passing through the display device 20 to perform imaging.

For the specific implementation details of step 03 and step 04, please refer to the above description. The description of whether the distance detecting device 40 detects whether there is an obstruction to select the imaging mode of the imaging device 32 will not be repeated here. In an example, when it is detected that the imaging device 32 is obstructed from the exposed stroke of the housing 10, it can be regarded as receiving the above-mentioned second instruction.

In one example, in the first imaging mode, the imaging device 32 is used to output a first image of a first number of pixels. In the second imaging mode, the imaging device 32 is used to output a second image of a second number of pixels, the second number being smaller than the first number.

Since in the first imaging mode, the imaging device 32 is not blocked, the amount of light received by the imaging device 32 is relatively large, and the output of the first image 60 of the first number of pixels can better reflect the imaging capability of the imaging device 32 and satisfy Users have high-resolution, high-quality shooting requirements, such as self-portraits, shooting landscapes, and video calls.

In the second imaging mode, the imaging device 32 is blocked by the display device 20, and the light transmittance of the display device 20 is generally lower than that of pure glass, for example, the light transmittance of the display device 20 is less than 60% , So that the amount of light received by the imaging device 32 is small. If the second image is still output with a higher number of pixels, the brightness of each pixel of the second image will be darker, which cannot truly reflect the real scene. The imaging device 32 outputs a second image 70 of a second number of pixels. The first number is smaller than the first number. By sacrificing the number of pixels of the second image 70, the authenticity of each pixel of the second image 70 is better.

For example, the first number may be the same as the total number of photosensitive cells in the photosensitive cell array 50. The second number may be one-half, one-third, one-quarter, one-sixth, one-eighth, one-ninth, and one-tenth of the total number of photosensitive units in the photosensitive unit array 50. , One-twelfth, one-sixteenth, etc., any number, which is not limited here.

For example, the ratio of the second quantity to the first quantity is 1:4, or, the ratio of the second quantity to the first quantity is 1:8, or, the ratio of the second quantity to the first quantity is 1:9, or, The ratio of the second quantity to the first quantity is 1:16, or, the ratio of the second quantity to the first quantity is 1:25, or, the ratio of the second quantity to the first quantity is 1:36, etc., which is not used here. limit.

Referring to FIG. 9, in an example, step 01 of the image acquisition method includes step 011: according to a first instruction, control the imaging device 32 to output a first image with a first number of pixels.

Step 02 of the image acquisition method includes step 021: according to the second instruction, the imaging device 32 is controlled to output a second image of a second number of pixels, the second number being smaller than the first number.

For the specific implementation details of step 011 and step 021, please refer to the above, and the related description of outputting the first image 60 and the second image 70 will not be repeated here.

Referring to the example shown in FIG. 10, in the first imaging mode, the imaging device 32 outputs the pixel value of one pixel of the first image 60 according to the signal value of one photosensitive unit.

Since more light can be received in the first imaging mode, the amount of light received by each pixel is relatively sufficient. At this time, the number of pixels in the first image 60 can be guaranteed first, so that the first image 60 can reflect more detail.

For example, as shown in FIG. 10, when the imaging device 32 outputs the first image 60, it can first output the signal values of the photosensitive units of the same color to generate an initial image of a single color channel, and then interpolate the vacancies in the initial image. Fill in the pixel values to obtain a target image with a single color channel. Through a similar method, the target images of all color channels can be obtained, and then the first image 60 is synthesized according to the target images of all colors.

Since the first image 60 includes signal values of multiple color channels, the first image 60 may be a color image.

Please refer to the example shown in FIG. 11, in the second imaging mode, the imaging device 32 outputs the pixel value of one pixel of the second image 70 according to the signal value of a minimum repeating unit 51.

Since the imaging device 32 is blocked by the display device 20 in the second imaging mode, the amount of light received by each pixel may not be sufficient. At this time, the electrical signals output by all the photosensitive units in a minimum repeating unit 51 can be compared with each other. Add and output to obtain the pixel value of one pixel of the second image 70 according to the signal value of a minimum repeating unit 51, so as to avoid the problem of too dark and distortion of the image caused by too little light received by some photosensitive units.

For example, as shown in FIG. 11, a pixel value of the second image 70 is obtained by the sum of the signal values of the photosensitive units in a minimum repeating unit 51: the R photosensitive unit, the two G photosensitive units, and the B photosensitive unit, so as to avoid R The photosensitive unit, the two G photosensitive units, and the B photosensitive unit receive too little light, resulting in excessive darkness and distortion. Thus, the pixel values of all pixels of the second image 70 can be correspondingly obtained, and the ratio of the number of pixels of the second image 70 to the number of photosensitive cells of the photosensitive array is 1:4.

Of course, according to the actual needs of the user, and further, one pixel value of the second image 70 can be obtained according to the signal values of the photosensitive units in more minimum repeating units 51, for example according to two, three, four, five The signal value of the photosensitive unit in the smallest repeating unit such as one, six, etc. obtains a pixel value of the second image 70. For example, the value of one pixel of the second image 70 is composed of the signal values of four photosensitive cells in the smallest repeating unit 51 arranged in 2 rows and 2 columns: 4 R photosensitive cells, 8 G photosensitive cells, and 4 B photosensitive cells. The sum is obtained, and the ratio of the number of pixels of the obtained second image 70 to the number of photosensitive units of the photosensitive array is 1:16.

Since the pixel value of the second image 70 is obtained based on the sum of the signal values of all photosensitive units in at least one minimum repeating unit 51, the second image 70 may be a black and white image, and no color information is reflected.

Referring to FIG. 12, in an example, step 011 of the image acquisition method includes step 0111: according to the first instruction, the imaging device 32 is controlled to output the pixel value of one pixel of the first image 60 according to the signal value of one photosensitive unit.

Step 021 of the image acquisition method includes step 0211: according to the second instruction, the imaging device 32 is controlled to output the pixel value of one pixel of the second image 70 according to the signal value of a minimum repeating unit 51.

For the specific implementation details of step 0111 and step 0211, please refer to the above. The related description of outputting the first image 60 and the second image 70 according to the signal value of the photosensitive unit will not be repeated here.
