[0051] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0052] It should be understood that the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0053] It should also be understood that in the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.
[0054] It should also be understood that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order.
[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.
[0056] Figure 1A A schematic diagram of an imaging module in a related art is shown. The pixel array in the imaging module includes a plurality of pixel units, and the pixels in each pixel unit are arranged in a 4*4 manner (i.e., 4 rows and 4 columns), wherein an OCL is set on every 2*2 pixels, that is, 4 pixels share one OCL (the OCL is recorded as 2*2 OCL in the embodiment of the present application).
[0057] It should be understood that each pixel unit corresponds to a single color channel.
[0058] Figure 1A The imaging module shown can realize a two-level image readout mode (Binning), that is, the imaging module can combine several pixels to use as one pixel. Figure 1B The schematic diagram of Binning principle is shown, in which every 2*2 pixels are combined as one pixel to read out the image data to realize the first-level Binning. Every 4*4 pixels are combined as one pixel to read out the image data to realize the second-level Binning.
[0059] It should be understood that the non-binning readout mode is used in high-resolution and high-brightness scenes to maximize the resolution; the first-level binning is used in medium-brightness scenes to take into account both the signal-to-noise ratio and the resolution; the second-level binning is used in dim scenes to maximize the signal-to-noise ratio.
[0060] It should also be understood that the multiple pixels covered by the OCL can have the PDAF function. Specifically, as shown in Figure 1, the four pixels under one OCL can detect phase information in four directions, namely, up, down, left, and right, and can be used to implement the PDAF function.
[0061] However, the crosstalk between pixels under the same OCL is serious, which will cause partial signal aliasing and reduce the clarity.
[0062] To solve the above problems, the embodiments of the present application provide an imaging module and an electronic device, wherein the imaging module can minimize the clarity loss caused by OCL crosstalk while taking into account the PDAF function. Compared with the imaging module solution in the related art, the clarity is better and the PDAF function can be retained.
[0063] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0064] It should be noted that the imaging module provided in the embodiments of the present application may also be referred to as an imaging device, an image sensor, a camera module, a camera device, etc., and these names are equivalent or interchangeable.
[0065] It should also be noted that the pixel array in the embodiment of the present application may also be referred to as a photosensitive area array or a Bayer array, and the three are equivalent or interchangeable.
[0066] It should also be noted that the lens array in the embodiment of the present application can also be called a microlens array, and the two are equivalent or interchangeable.
[0067] It should also be noted that the correspondence between pixels and lenses in the implementation of the present application can be understood as pixels being covered by corresponding lenses.
[0068] An embodiment of the present application provides an imaging module, which may include a pixel array and a lens array.
[0069] It should be noted that the pixel array may include a plurality of pixel units, each of the plurality of pixel units includes a plurality of pixels, and the plurality of pixels are arranged in a two-dimensional manner.
[0070] It should be understood that the pixel unit may also be referred to as a pixel block, a pixel group, etc., which are equivalent or interchangeable.
[0071] It should also be understood that the pixel array is composed of individual pixels, which can correspond to each pixel in each image (i.e., the image collected by the imaging module). Among them, the function of each pixel is to convert the sensed light signal into an electrical signal, and convert it into a digital signal through a readout circuit, thereby completing the process of digitizing the real scene. Specifically, each pixel can include a photosensitive element and a readout circuit. After the signal of each pixel is processed by an analog signal, it is handed over to an analog to digital converter (ADC) for analog-to-digital conversion and then output to the digital processing module, thereby completing the process of digitizing the real scene.
[0072] Among them, the photosensitive element can be a photodiode (PD); each PD has a light receiving surface. When the incident light reaches the light receiving surface of each PD, the PD can absorb the incident light of the corresponding wavelength in the incident light and convert the absorbed incident light into photoelectrons and output it to the readout circuit corresponding to the PD.
[0073] It should be noted that the pixel unit can be understood as the smallest unit that can be repeatedly set.
[0074] Wherein, the pixel array includes a plurality of pixel units, and it can be understood that the pixel array can be divided into pixel units that can be repeatedly set. Wherein, each pixel unit can include a plurality of pixels of the same number. In some embodiments, the pixels in each pixel unit can be arranged in a two-dimensional manner, or in other words, the plurality of pixels in each pixel unit can be arranged in a two-dimensional array. In other words, the pixels in each pixel unit can be arranged in a first direction and a second direction in a two-dimensional plane. Wherein, the first direction and the second direction are perpendicular, the first direction can be the X-axis direction in the two-dimensional plane, or the horizontal direction, or it can also be understood as a row in the array; the second direction can be the Y-axis direction in the two-dimensional plane, or the vertical direction, or it can also be understood as a column in the array.
[0075] In an embodiment of the present application, each pixel unit may include n1*n2 pixels, where n1 is the number of pixels in a first direction in the plane, and n2 is the number of pixels in a second direction in the plane, or in other words, n1 is the number of rows in a two-dimensional plane, and n2 is the number of columns in the two-dimensional plane.
[0076] It should be noted that n1 and n2 are both integers greater than or equal to 2. The values of n1 and n2 may be different, wherein n1 may be less than n2, for example, each pixel unit may include 3*4 pixels; n1 may also be greater than n2, for example, each pixel unit may include 4*3 pixels. In addition, the values of n1 and n2 may also be the same, for example, each pixel unit may include 4*4 pixels, 5*5 pixels, etc.
[0077] It should also be noted that one pixel unit can sense one color, and different pixel units can sense the same or different colors. Specifically, each pixel unit can be provided with a filter, which can be any one of the three types of red (R) / green (G) / blue (B), and can only transmit light of the corresponding wavelengths of red, green, and blue, respectively. By setting the filter, each pixel unit can only sense one color.
[0078] In an embodiment of the present application, the lens array may include a plurality of lenses. The plurality of lenses may be of different types, and different lens types may correspond to different numbers of pixels and / or pixel arrangements.
[0079] It should be noted that the lens can also be called a microlens or an on-chip microlens (OCL). The lens can focus light on the opening of the pixel photosensitive area to increase the photoelectric conversion efficiency.
[0080] In some embodiments, the lens array may include a plurality of first lenses and a plurality of second lenses.
[0081] Wherein, every N pixels in the first area of each pixel unit of the pixel array correspond to a first lens; and every M pixels in the second area of each pixel unit correspond to a second lens.
[0082] It should be noted that N and M are both integers greater than or equal to 1.
[0083] It should also be noted that every N pixels corresponds to a first lens, which can be understood as every N pixels are covered by a first lens, or in other words, one first lens can cover N pixels.
[0084] It should also be noted that when N is greater than or equal to 2 (i.e., the number of pixels corresponding to the first lens is greater than or equal to 2), the two or more pixels can be arranged in the first direction and / or the second direction. It is understandable that when the first lens covers N (N>=2) pixels, the N pixels covered by the first lens can also be arranged in the first direction and the second direction at the same time, that is, the first lens is N1*N2 OCL, N=N1*N2, for example Figure 2BAs shown, the first lens 21 may be a 2*2 OCL. In addition, the first lens covering R pixels may be arranged in the first direction, that is, the first lens is a 1*N OCL, for example Figure 2C As shown, the first lens 21 is 1*2OCL. The N pixels covered by the first lens can also be arranged in the second direction, that is, the first lens is N*1OCL, for example Figure 2D As shown, the first lens 21 is a 2*1 OCL.
[0085] In addition, every M pixels corresponds to one second lens, which can be understood as, every M pixels are covered by one second lens, or in other words, one second lens can cover M pixels.
[0086] It should be noted that when M is greater than or equal to 2 (i.e., the number of pixels M corresponding to the second lens is greater than or equal to 2), the two or more pixels may be arranged in the first direction and / or the second direction. It is understandable that when the second lens covers M (M>=2) pixels, the M pixels may all be arranged in the first direction, i.e., the second lens is 1*M OCL, for example Figure 3B As shown, the second lens 22 is 1*2OCL. The M pixels covered by the second lens can also be arranged in the second direction, that is, the second lens is M*1OCL, for example Figure 2C As shown, the second lens 22 is a 2*1 OCL. In addition, the M pixels covered by the second lens can also be arranged in the first direction and the second direction at the same time, that is, the second lens is an M1*M2 OCL, M=M1*M2, for example Figure 2A As shown, the second lens 22 may be a 2*2 OCL.
[0087] In the embodiment of the present application, each pixel unit of the pixel array can be divided into two areas: a first area and a second area, and the pixels in each area can correspond to different types of lenses.
[0088] Specifically, the pixels in the first area of each pixel unit may be covered by one or more first lenses, and one first lens covers N pixels in the first area; the pixels in the second area of each pixel unit may be covered by one or more second lenses, and one second lens may cover M pixels in the second area.
[0089] It should also be noted that the shapes of the first lens and the second lens can be circular, elliptical, rectangular, square, or other shapes. In addition, the shapes of the first lens and the second lens can be the same or different, and the embodiments of the present application do not limit this.
[0090] In some embodiments, the number N of pixels corresponding to the first lens and / or the number M of pixels corresponding to the second lens are integers less than a first threshold.
[0091] It should be noted that the first threshold may be the number of pixels covered by the lens in the related art. For example, the first threshold may be 4, 3, 2, etc., and the present application does not impose any limitation on this.
[0092] It should also be noted that the values of N and M can be the same or different, and the embodiments of the present application do not limit this.
[0093] In a possible implementation, the number of pixels N corresponding to each first lens is less than the first threshold, and the number of pixels M corresponding to each second lens is not limited. It can be understood that the first lens in the imaging module can cover fewer pixels (that is, N is less than the first threshold), so that the number of pixels sharing the same lens can be reduced, and the crosstalk between pixels can be reduced.
[0094] For example, the first threshold may be 2, the number of pixels N corresponding to the first lens may be 1 (N<2), and the number of pixels M corresponding to the second lens may be 4. Figure 2A An imaging module shown includes 4 pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 4*4 pixels (each smallest square in the figure represents a pixel). The first area of each pixel unit includes 2*2 pixels on the upper left side and 2*2 pixels on the lower right side of the pixel unit, and the second area of each pixel unit includes 2*2 pixels on the upper right side and 2*2 pixels on the lower left side of the pixel unit. Figure 2A As shown, each pixel in the first area corresponds to a first lens 21, or in other words, each first lens 21 covers one pixel. Every four pixels in the second area 24 correspond to a second lens 22, or in other words, each second lens 22 covers four pixels.
[0095] In another possible implementation, the number of pixels N corresponding to the first lens is not limited, and the number of pixels M corresponding to the second lens is less than the first threshold. It can be understood that the second lens in the imaging module can cover fewer pixels (that is, M is less than the first threshold), so that the number of pixels sharing the same lens can be reduced, and the crosstalk between pixels can be reduced.
[0096] For example, the first threshold may be 2, the number of pixels N corresponding to the first lens is 4, and the number of pixels M corresponding to the second lens is 1 (M<2). Figure 2B An imaging module shown includes 4 pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 4*4 pixels (each smallest square in the figure represents a pixel). The first area of each pixel unit includes 2*2 pixels on the upper left side and 2*2 pixels on the lower right side of the pixel unit, and the second area of each pixel unit includes 2*2 pixels on the upper right side and 2*2 pixels on the lower left side of the pixel unit. Figure 2BAs shown, every 4 pixels in the first area correspond to a first lens 21, or in other words, each first lens 21 covers 4 pixels. Every pixel in the second area corresponds to a second lens 22, or in other words, each second lens 22 covers 1 pixel.
[0097] In another possible implementation, the number of pixels N corresponding to the first lens and the number of pixels M corresponding to the second lens are both less than the first threshold. It can be understood that the first lens and the second lens in the imaging module can both cover fewer pixels (that is, N and M are both less than the first threshold), so that the number of pixels sharing the same lens can be reduced, and the crosstalk between pixels can be reduced.
[0098] In one example, the first threshold may be 3, and the values of N and M are both 2 (N<3 and M<3). Figure 2C An imaging module shown includes 4 pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 4*4 pixels (each smallest square in the figure represents a pixel). The first area of each pixel unit includes 2*2 pixels on the upper left side and 2*2 pixels on the lower right side of the pixel unit, and the second area of each pixel unit includes 2*2 pixels on the upper right side and 2*2 pixels on the lower left side of the pixel unit. Figure 2C As shown, every two pixels in the first region correspond to one first lens 21, or in other words, each first lens 21 covers two pixels. Every two pixels in the second region correspond to one second lens 22, or in other words, each second lens 22 covers two pixels.
[0099] In another example, when the first threshold is 3, the value of N is 2, and the value of M is 1 (both N and M are less than the first threshold 3). Figure 2D An imaging module shown includes 4 pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 4*4 pixels (each smallest square in the figure represents a pixel). The first area of each pixel unit includes 2*2 pixels on the upper left side and 2*2 pixels on the lower right side of the pixel unit, and the second area of each pixel unit includes 2*2 pixels on the upper right side and 2*2 pixels on the lower left side of the pixel unit. Figure 2D As shown, each pixel in the first area corresponds to two first lenses 21, or each first lens 21 covers two pixels. Each pixel in the second area corresponds to one second lens 22, or each second lens 22 covers one pixel.
[0100] It can be understood that in the imaging module in the embodiment of the present application, each first lens and / or each second lens in the lens array covers fewer pixels, which can reduce the crosstalk between pixels to a certain extent, which is beneficial to improving image clarity.
[0101] In some embodiments, the first region of each pixel unit may include one or more first sub-regions, and the second region of each pixel unit may include one or more second sub-regions.
[0102] It can be understood that the first area of each pixel unit can be divided into one or more first sub-areas, and every N pixels in each first sub-area corresponds to a first lens.
[0103] It should be noted that each first sub-region includes at least N pixels, or in other words, the number of pixels included in each first sub-region is greater than or equal to N.
[0104] In one example, reference FIG. 2A to FIG. 2B As shown, the first area in each pixel unit (for example, pixel unit 81 to pixel unit 84) can be divided into two first sub-areas (recorded as first sub-area A and first sub-area B), wherein the first sub-area A includes 2*2 pixels on the upper left side of each pixel unit, and the first sub-area B includes 2*2 pixels on the lower right side of each pixel unit.
[0105] In another example, reference Figure 3A and Figure 3B As shown, the first area in each pixel unit (eg, pixel unit 81 to pixel unit 84) may include only one area, namely, 2*2 pixels in the middle of each pixel unit.
[0106] It can also be understood that the second area of each pixel unit can be divided into one or more second sub-areas, and every M pixels in each second sub-area corresponds to a second lens.
[0107] It should be noted that each second sub-region includes at least M pixels, or in other words, the number of pixels included in each second sub-region is greater than or equal to M.
[0108] In one example, reference FIG. 2A to FIG. 2B As shown, the second area in each pixel unit (for example, pixel unit 81 to pixel unit 84) can be divided into two second sub-areas (recorded as second sub-area A and second sub-area B), wherein the second sub-area A includes 2*2 pixels on the upper right side of each pixel unit, and the second sub-area B includes 2*2 pixels on the lower left side of each pixel unit.
[0109] In another example, reference Figure 3A and Figure 3B As shown, the second area in each pixel unit (eg, pixel unit 81 to pixel unit 84) may include only one area, namely, 12 pixels at the edge of each pixel unit.
[0110] In some embodiments, when the number of the first sub-regions includes a plurality, the plurality of first sub-regions are not adjacent to each other, and / or when the number of the second region includes a plurality, the plurality of second sub-regions are not adjacent to each other.
[0111] It is understandable that, in order to reduce the crosstalk between adjacent lenses, when the number of the first sub-regions includes multiple, the multiple first sub-regions may not be adjacent to each other. For example, the first sub-region may be adjacent to the second region, and the multiple first sub-regions may be separated by the second region (when the second region includes multiple second sub-regions, the multiple first sub-regions may be separated by any second sub-region).
[0112] It is also understandable that, in order to reduce crosstalk between adjacent lenses, when the number of second sub-regions includes multiple, the multiple second sub-regions may not be adjacent to each other. For example, the second sub-region may be adjacent to the first region, and the multiple second sub-regions may be separated by the first region (when the first region includes multiple first sub-regions, the multiple second sub-regions may be separated by any one of the first sub-regions).
[0113] For example, reference Figure 4 The imaging module shown in FIG. 1 includes four pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 3*3 pixels (each smallest square in the figure represents a pixel). Figure 4 As shown, the first area in each pixel unit includes two first sub-areas (referred to as the first sub-area A and the first sub-area B), wherein the first sub-area A includes three pixels on the left side of the pixel unit, and the first sub-area B includes three pixels on the right side of the pixel unit. The three pixels in the first sub-area A and the first sub-area B correspond to one first lens 21. In addition, the second sub-area includes three pixels located in the middle of the pixel unit, and each pixel in the second sub-area corresponds to one second lens 22, or in other words, the first lens 21 covers three pixels in the first sub-area. The second area can be located in the middle of the two first sub-areas, separating the first sub-area A and the second sub-area B, so as to reduce the crosstalk between the first lens 21 corresponding to the first sub-area A and the first lens 21 corresponding to the first sub-area B.
[0114] In some embodiments, when the number of the first sub-regions includes a plurality and the number of the second sub-regions includes a plurality, the plurality of second sub-regions may be disposed at intervals from the plurality of first sub-regions.
[0115] It can be understood that the first sub-region and the second sub-region are connected to each other, and two different first sub-regions are separated by the second sub-region, and different second sub-regions are separated by the first sub-region. The first sub-region and the second sub-region are spaced apart to avoid crosstalk between adjacent lenses.
[0116] For example, reference Figure 5 An imaging module shown in FIG. 1 includes four pixel units (pixel unit 81 to pixel unit 84), each pixel unit includes 4*4 pixels (each smallest square in the figure represents one pixel). Figure 5 As shown, the first area in each pixel unit includes four first sub-areas (recorded as first sub-area A to first sub-area D), wherein the first sub-area A includes the first pixel in the first row and the first pixel in the second row in the pixel unit, the first sub-area B includes the third pixel in the first row and the third pixel in the second row in the pixel unit, the first sub-area C includes the second pixel in the third row and the second pixel in the fourth row in the pixel unit, and the first sub-area D includes the fourth pixel in the third row and the fourth pixel in the fourth row in the pixel unit.
[0117] In addition, if Figure 5 As shown, the second area in each pixel unit also includes four second sub-areas (recorded as second sub-areas A to second sub-areas D), wherein the second sub-area A includes the second pixel in the first row and the second pixel in the second row in the pixel unit, the second sub-area B includes the fourth pixel in the first row and the fourth pixel in the second row in the pixel unit, the first sub-area C includes the first pixel in the third row and the first pixel in the fourth row in the pixel unit, and the first sub-area D includes the third pixel in the third row and the third pixel in the fourth row in the pixel unit. As can be seen from Figure 5, each first sub-area can be adjacent to a second sub-area, and the second sub-area and the first sub-area can be arranged at intervals to reduce crosstalk between adjacent lenses.
[0118] In some embodiments, the plurality of first sub-regions are diagonally adjacent to each other, and / or the plurality of second sub-regions are diagonally adjacent to each other.
[0119] It can be understood that, in addition to the first sub-region and the second sub-region being arranged at intervals, a plurality of first sub-regions can be arranged diagonally adjacent to each other, which can also reduce the crosstalk between adjacent lenses. FIG. 2A to FIG. 2D As shown, the first area in each pixel unit includes a first sub-area on the upper left side and a first sub-area on the lower right side, and the two first sub-areas are diagonally adjacent; the second area includes a second sub-area on the upper right side and a second sub-area on the lower left side, and the two second sub-areas are diagonally adjacent.
[0120] In some embodiments, the second region of each pixel unit may surround the first region.
[0121] It can be understood that the number of pixels N covered by the first lens is greater than the number of pixels N covered by the second lens. In each pixel unit, the first region can be spaced from the edge of the pixel unit by at least one second region (which can also be understood as being spaced from at least one pixel), or in other words, the first lens covers the pixels at non-edge positions in the pixel unit. In this way, crosstalk between the pixels in the current pixel unit and the pixels in adjacent other pixel units can be reduced.
[0122] Exemplarily, referring to Figure 3A and Figure 3B as shown, pixel unit 81 corresponds to red (R), pixel units 82 and 83 correspond to green (G), and pixel unit 84 corresponds to blue (B). In Figure 3A , the first lens 21 in each pixel unit covers 2×2 pixels, and the 2×2 pixels covered by the first lens 21 are located in the middle part of the 4×4 pixels in the pixel unit, spaced from the edge of the pixel unit by one pixel. The edge pixels of each pixel unit are covered by the second lens 22. In Figure 3B , the first lens 21 in each pixel unit covers 1×2 pixels, and the first lens 21 is located in the middle part of the 4×4 pixels in the pixel unit. In this way, the crosstalk with adjacent pixel units of other colors is smaller.
[0123] In an embodiment of the present application, the number of pixels M corresponding to the second lens can be less than the number of pixels N corresponding to the first lens, that is, M < N.
[0124] In some embodiments, the value of M can be less than the first threshold, and the value of N is not limited. For example, referring to Figure 2B as shown, the value of M can be 1 (less than the first threshold 2), and the value of N is the same as the number of pixels covered by the lens in the related art (for example, 4).
[0125] In some embodiments, N can be understood as the first threshold, or in other words, the first threshold is the value of N.
[0126] In some embodiments, the value of N can be less than the first threshold, that is, M < N < the first threshold. For example, when the first threshold is 4, the value of M can be 1, and the value of N can be 2, as Figure 2D shown.
[0127] It can be understood that since the first lens in the pixel unit can cover two or more pixels, the two or more pixels can distinguish the phase information in the first direction or the second direction in the two-dimensional plane. Therefore, the function of PDAF can be realized through the first lens. And the second lens in the pixel unit covers fewer pixels (the number of pixels M is less than N), which can reduce the crosstalk between pixels to a certain extent and is beneficial to improving the image clarity.
[0128] In another embodiment of the present application, the number of pixels M corresponding to the first lens may be the same as the number of pixels N corresponding to the second lens, that is, M=N, and both M and N are smaller than the first threshold.
[0129] That is, each pixel unit may include only one type of lens, which may cover fewer pixels (ie, the number is less than the first threshold), thereby reducing the number of pixels sharing the same lens and reducing crosstalk between pixels.
[0130] It should be noted that when the values of M and N are the same, both M and N need to be greater than 2, that is, M>2 and N>2, to ensure that the pixels under each lens can obtain phase information, thereby realizing the PDAF function.
[0131] In the embodiment of the present application, both M and N are less than a first threshold, where the first threshold may be 3 or 4.
[0132] In a possible implementation manner, the N pixels corresponding to the first lens and the M pixels corresponding to the second lens are arranged in the same manner.
[0133] In one example, reference Fig. 6A and Figure 6B As shown, M=N=2, each pixel unit (pixel units 81-84) includes 4*4 pixels, every two pixels in each pixel unit correspond to one lens, and each lens can cover 2 pixels.
[0134] In another example, reference Fig. 7A and Figure 7B As shown, M=N=3, each pixel unit (pixel units 81-84) includes 3*3 pixels. Every 3 pixel units in each pixel unit may correspond to a lens, and each lens covers 3 pixels.
[0135] In another possible implementation, when M=N, N pixels corresponding to the first lens are arranged in a first direction, and M pixels corresponding to the second lens are arranged in a second direction; wherein the first direction is perpendicular to the second direction.
[0136] Specifically, in each pixel unit, the N pixels covered by the first lens in the first area can be arranged in a 1*N manner, and the M pixels covered by the second lens in the second area can be arranged in an M*1 manner. Figure 8 As shown, the two pixels corresponding to the first lens 21 in the first area of each pixel unit are arranged in a 1*2 manner, that is, the first lens is 1*2 OCL. The two pixels corresponding to the second lens 22 in the second area of each pixel unit are arranged in a 2*1 manner, that is, the second lens is 2*1 OCL.
[0137] Alternatively, the N pixels covered by the first lens in the first area of each pixel unit may be arranged in an N*1 manner, and the M pixels covered by the second lens in the second area may be arranged in a 1*M manner. Fig. 9 As shown, the two pixels corresponding to the first lens 21 in the first area of each pixel unit are arranged in a 2*1 manner, that is, the first lens is 2*1 OCL. The two pixels corresponding to the second lens 22 in the second area of each pixel unit are arranged in a 1*2 manner, that is, the second lens is 1*2 OCL.
[0138] It can be understood that the first lens in each pixel unit can obtain phase information in the first direction, and the second lens in each pixel unit can obtain phase information in the second direction. In this way, in one pixel unit, phase information in each direction can be obtained through different arrangement directions, thereby obtaining complete phase information and realizing a more accurate PDAF function.
[0139] In some embodiments, the plurality of pixel units include a first pixel unit and a second pixel unit, wherein:
[0140] The number N of pixels corresponding to the first lens in the first pixel unit is different from the number N of pixels corresponding to the first lens in the second pixel unit; and / or,
[0141] The number M of pixels corresponding to the second lens in the first pixel unit is different from the number M of pixels corresponding to the second lens in the second pixel unit.
[0142] It should be noted that the first pixel unit and the second pixel unit may be any two different pixel units among the plurality of pixel units. For example, the first pixel unit and the second pixel unit may be two different pixel units corresponding to the same color among the plurality of pixel units. For example, the first pixel unit and the second pixel unit may be two different pixel units among the plurality of pixel units corresponding to green (G).
[0143] In a possible implementation, the number of pixels N corresponding to the first lens in the first pixel unit is different from the number of pixels N corresponding to the first lens in the second pixel unit, and the number of pixels M corresponding to the second lens in the first pixel unit is the same as the number of pixels M corresponding to the second lens in the second pixel unit.
[0144] For example, reference Fig.10As shown, in the first area of the pixel unit 81 and the pixel unit 84, every 4 (i.e., N=4) pixels correspond to a first lens 21, and in the second area, every (i.e., M=1) pixel corresponds to a second lens 22. In the first area of the pixel unit 82 and the pixel unit 83, every 2 (i.e., N=2) pixels correspond to a first lens 21, and in the second area, every (i.e., M=1) pixel corresponds to a second lens 22. In other words, the number of pixels covered by the first lens corresponding to the pixel unit 81 and the pixel unit 84 is N=4, which is different from the number of pixels covered by the first lens corresponding to the pixel unit 82 and the pixel unit 83 is N=2.
[0145] In another possible implementation, the number of pixels N corresponding to the first lens in the first pixel unit is the same as the number of pixels N corresponding to the first lens in the second pixel unit, and the number of pixels M corresponding to the second lens in the first pixel unit is different from the number of pixels M corresponding to the second lens in the second pixel unit.
[0146] For example, reference Fig.11 As shown, in the first area of the pixel unit 81 and the pixel unit 84, every 4 (i.e., N=4) pixels correspond to a first lens 21, and in the second area, every (i.e., M=1) pixel corresponds to a second lens 22. In the first area of the pixel unit 82 and the pixel unit 83, every 4 (i.e., N=4) pixels correspond to a first lens 21, and in the second area, every two (i.e., M=2) pixels correspond to a second lens 22. In other words, the number of pixels covered by the second lens corresponding to the pixel unit 81 and the pixel unit 84 is M=1, which is different from the number of pixels covered by the second lens corresponding to the pixel unit 82 and the pixel unit 83 is M=2.
[0147] In another possible implementation, the number of pixels N corresponding to the first lens in the first pixel unit is different from the number of pixels N corresponding to the first lens in the second pixel unit, and the number of pixels M corresponding to the second lens in the first pixel unit is also different from the number of pixels M corresponding to the second lens in the second pixel unit.
[0148] For example, reference Fig.12As described, in the first area of the pixel unit 81 and the pixel unit 84, every 4 (i.e., N=4) pixels correspond to a first lens 21, and every (i.e., M=1) pixel in the second area corresponds to a second lens 22. In the pixel unit 82 and the pixel unit 83, every 1 (i.e., N=1) pixel in the first area corresponds to a first lens 21, and every two (i.e., M=2) pixels in the second area correspond to a second lens 22. In other words, the number of pixels covered by the first lens corresponding to the pixel unit 81 and the pixel unit 84 is N=4, which is different from the number of pixels covered by the first lens corresponding to the pixel unit 81 and the pixel unit 84 is N=1. In addition, the number of pixels covered by the second lens corresponding to the pixel unit 81 and the pixel unit 84 is M=1, which is also different from the number of pixels covered by the second lens corresponding to the pixel unit 81 and the pixel unit 84 is M=2.
[0149] In summary, the number of pixels corresponding to the first lens and the second lens in each pixel unit in the imaging module can be different, so that flexible setting of the lens and more accurate acquisition of PDFA information can be achieved.
[0150] In some embodiments, the plurality of pixel units include a first pixel unit and a second pixel unit, wherein:
[0151] The arrangement of the N pixels corresponding to the first lens in the first pixel unit is different from the arrangement of the N pixels corresponding to the first lens in the second pixel unit; and / or,
[0152] The arrangement of the M pixels corresponding to the second lens in the first pixel unit is different from the arrangement of the M pixels corresponding to the second lens in the second pixel unit.
[0153] It should be noted that the first pixel unit and the second pixel unit may be any two different pixel units among the plurality of pixel units. For example, the first pixel unit and the second pixel unit may be two different pixel units corresponding to the same color among the plurality of pixel units. For example, the first pixel unit and the second pixel unit may be two different pixel units among the plurality of pixel units corresponding to green (G).
[0154] In a possible implementation, an arrangement of N pixels corresponding to the first lens in the first pixel unit is different from an arrangement of N pixels corresponding to the first lens in the second pixel unit, and an arrangement of M pixels corresponding to the second lens in the first pixel unit is the same as an arrangement of M pixels corresponding to the second lens in the second pixel unit.
[0155] For example, reference Fig.13As described, every 2 pixels (i.e., N=M=2) in the pixel units 81 to 84 correspond to one lens (every 2 pixels in the first area correspond to one first lens 21, and every 2 pixels in the second area correspond to one second lens 22). The pixels covered by the first lens 21 in the pixel units 81 and 84 are arranged in a 2*1 manner, and the pixels covered by the first lens 21 in the pixel units 82 and 83 are arranged in a 1*2 manner. The arrangement of the pixels covered by the first lens 21 in the pixel units 81 and 84 is different from the arrangement of the pixels covered by the first lens in the pixel units 82 and 83. The arrangement of the pixels covered by the second lens 22 in the pixel units 81 and 84 is the same as the arrangement of the pixels covered by the second lens 22 in the pixel units 82 and 83, both of which are arranged in a 2*1 manner.
[0156] In a possible implementation, an arrangement mode of N pixels corresponding to the first lens in the first pixel unit is the same as an arrangement mode of N pixels corresponding to the first lens in the second pixel unit, and an arrangement mode of M pixels corresponding to the second lens in the first pixel unit is different from an arrangement mode of M pixels corresponding to the second lens in the second pixel unit.
[0157] For example, reference Fig.14 As described above, every 2 pixels (i.e., N=M=2) in the pixel units 81 to 84 correspond to one lens (every 2 pixels in the first area correspond to one first lens 21, and every 2 pixels in the second area correspond to one second lens 22). The arrangement of the pixels covered by the first lens 21 in the pixel units 81 and 84 is the same as the arrangement of the pixels covered by the first lens 21 in the pixel units 82 and 83, both of which are arranged in a 2*1 manner. The arrangement of the pixels covered by the second lens 22 in the pixel units 81 and 84 is 1*2, and the arrangement of the pixels covered by the second lens 22 in the pixel units 82 and 83 is 2*1, and the two arrangement manners are different.
[0158] In a possible implementation, an arrangement of N pixels corresponding to the first lens in the first pixel unit is different from an arrangement of N pixels corresponding to the first lens in the second pixel unit, and an arrangement of M pixels corresponding to the second lens in the first pixel unit is also different from an arrangement of M pixels corresponding to the second lens in the second pixel unit.
[0159] For example, reference Fig.15As shown, every 2 pixels (i.e., N=M=2) in pixel units 81 to 84 correspond to one lens (every 2 pixels in the first area correspond to one first lens 21, and every 2 pixels in the second area correspond to one second lens 22). Among them, the arrangement of pixels covered by the first lens 21 and the arrangement of pixels covered by the second lens 22 in pixel units 81 and 84 is 2*1. The arrangement of pixels covered by the first lens 21 and the arrangement of pixels covered by the second lens 22 in pixel units 82 and 83 are both 2*1. The arrangement of the first lens and the second lens in pixel units 81 and 84 is different from that in pixel units 82 and 83.
[0160] In this way, the arrangement directions of the pixels covered by the lenses in the two pixel units with different settings are different. In this way, the phase information in each direction can be obtained, thereby obtaining complete phase information and realizing a more accurate PDAF function.
[0161] The imaging module provided in the embodiment of the present application is described in detail below in conjunction with specific application scenarios.
[0162] It should be noted that the following description is made by taking an application scenario of an imaging module in which pixels in a pixel unit are arranged in K*K (K>=3) as an example.
[0163] The embodiment of the present application proposes a new OCL design for a pixel array arrangement of K*K (for example, K=4), which minimizes the clarity loss caused by OCL crosstalk while taking into account the PDAF phase detection autofocus function. Compared with the existing solution, the clarity is better and the PDAF function can be retained.
[0164] The method provided in the embodiment of the present application reduces the crosstalk between pixels by reducing the number of pixels sharing the same OCL.
[0165] In one implementation, the shared OCL density can be reduced. Fig.16 A schematic diagram of a pixel array shown in FIG. Figure 1A Compared with the imaging module shown in the figure, half of the 2*2 OCL in each pixel unit in the related art can be replaced with 1*1 OCL. In this way, the remaining 2 2*2 OCL can still be used for the PDAF function, which can reduce the crosstalk between pixels to a certain extent.
[0166] In another implementation, the number of pixels sharing the OCL is reduced. Fig.17A and Fig. 17B As shown, using 2*1OCL (such as Fig.17A As shown) or use 1*2OCL (as Fig. 17BAs shown in the figure, 2*2OCL in the related art is replaced by 2*1OCL; 2*1OCL and 1*2OCL can distinguish the phase information of up and down or left and right, can realize the function of PDAF, and the crosstalk between pixels is reduced from 4 to 2; it is beneficial to improve the clarity.
[0167] In yet another implementation, referring to Fig.18 As shown in FIG. 1 , the density of the shared OCL can be reduced while reducing the number of pixels of the shared OCL. Fig.19 As shown, it can be Fig.18 The density of shared OCL can be further reduced on the basis of , and 1*2 OCL can only retain one pair in the object pixel.
[0168] It should be noted that, in the above implementation, the position of the 2*2 OCL or 2*1 OCL can be adjusted. Fig. 20 As shown, place the 2*2 OCL in the middle of the 4*4 array of pixel units. Fig.21 As shown, the 2*1 OCL can be placed in the middle of the 4x4 pixel array of the pixel unit, so that the crosstalk with other colors next door is smaller.
