As Fig. 1 to as shown in figure 3, according to invention one first preferred embodiment an array camera module be elucidated with, wherein The array camera module includes one first camera module 10 and one second camera module 20, to pass through the first camera shooting mould Group 10 and second camera module 20 cooperation, realize the imaging function of " optical zoom ".Particularly, in the present invention, described The equivalent focal length f2 less than second camera module 20, correspondingly, institute is set in the equivalent focal length f1 of first camera module 10 The field angle FOV1 for stating the first camera module 10 is greater than the field angle FOV2 of second camera module 20.That is, at this In invention, as shown in Figure 1, first camera module 10 is configured as a wide-angle imaging mould group, second camera module 20 are configured as a focal length camera module, and in shooting process, the wide-angle imaging mould group viewfinder range is wider, still It is difficult the details that shooting understands distant objects, the optical lens viewfinder range of the focal length camera module is narrow, but can clap Relatively farther object is taken the photograph, to arrange in pairs or groups by the wide-angle and the complementary of the focal length camera module, and utilizes backstage phase The image processing algorithm answered realizes the function of " optical zoom ".

The existing array camera module with " optical zoom " function, since its focal length camera module has relatively Big height dimension causes its product whole height that can not decline.Limitation in this size greatly restricts the array The application of camera module is especially unable to satisfy the growth requirement of electronic equipment slimization instantly.Meanwhile it is as previously mentioned, existing The array camera module with " optical zoom " function, focal length camera module and the corresponding photosensitive core of wide-angle imaging mould group Piece is all color sensitive chip.During Image Acquisition, focal length camera module is since oneself height limits, light-inletting quantity Deficiency leads to focal length camera module color image hair collected along with the photoperceptivity of color sensitive chip is relatively weak Secretly.This defect, ambient light than it is darker in the case where, more obviously, cause by focal length camera module coloured silk collected Chromatic graph piece is unsuitable in subsequent composograph even adversely affecting image synthesis.

Correspondingly, the array camera module provided by the present invention is dedicated to solving the array camera module whole The technical problem of body size and imaging effect etc., to better adapt to the trend of electronic equipment instantly.

More specifically, as shown in figure 3, in the preferred embodiment of the invention, first camera module 10 includes One first sensitive chip 11 and one first optical lens 12, first optical lens 12 are held in the described first photosensitive core The photosensitive path of piece 11, thus can be along this by the imaging ray of first optical lens 12 measured target collected Photosensitive path is supported to first sensitive chip 11, and imaging reaction occurs at first sensitive chip 11.Described second Camera module 20 includes one second sensitive chip 21 and one second optical lens 22, analogously, second optical lens 22 It is held in the photosensitive path of second sensitive chip 21, thus by the second optics measured target collected Imaging ray can be supported along the photosensitive path to second sensitive chip 21, and be occurred at second sensitive chip 21 Imaging reaction.

Particularly, in the preferred embodiment of the invention, first optical lens 12 is corresponding described first photosensitive Chip 11 is a color sensitive chip 110, and corresponding second sensitive chip 21 of second optical lens 22 is a black and white Sensitive chip 210.That is, in the present invention, the sensitive chip of the focal length camera module is by an existing color sensitive Chip replaces with a black and white sensitive chip, compared to color sensitive chip, the unit pixel of the black and white sensitive chip 210 2130 sizes can be contracted by, thus in the case where meeting equal pixel quantitative requirement, the ruler of the black and white sensitive chip 210 It is very little, the color sensitive chip of equal pixel quantity is compared, can be contracted by.Correspondingly, described in second camera module 20 When the size of second sensitive chip 21 is contracted by, second optical lens 22 of second camera module 20 can be more adjacent Near-earth is installed on the top side of second sensitive chip 21.At this point, from visual effect, second optical lens 22 Installation site can more sink so that the overall height dimension of the array camera module can effectively be reduced.

More specifically, those skilled in the art will be appreciated that, as shown in figure 3, the color sensitive chip 110 has Multilayered structure, including a microlens layer 111, a color filter layer 112 and a photosensitive layer 113, wherein by first light The measured target light collected of camera lens 12 is learned when supporting the extremely color sensitive chip 110, which first penetrates described micro- Mirror layer 111, and be filtered by the color filter layer 112, it is final to support to each pixel 1130 of the photosensitive layer 113 The light be monochromatic light (red, green or blue).Those skilled in the art will be appreciated that, during later period imaging, need with The pixel 1130 of color sensitive chip 110 described in one group constructs an imaging unit, such as with the every 4 color sensitive cores The pixel 1130 of piece 110 constitutes an imaging unit, and the colour information of measured target script is restored by corresponding algorithm. Based on such imaging speciality, existing color sensitive chip, the size of unit pixel is typically larger than 1*1um or more, such as 1.2*1.2um, to ensure that each pixel 1130 can collect corresponding monochromatic optical information.

In simple terms, compared to the color sensitive chip 110, the black and white sensitive chip 210 and the color sensitive The difference of chip 110 is only that the black and white sensitive chip 210 between the microlens layer 211 and the photosensitive layer 213 It is not provided with the color filter layer.That is, final support to each pixel 2130 of the black and white sensitive chip 210 The light is white light.In addition, not having the colour information of acquisition measured target for the black and white sensitive chip 210 Function, the pixel 2130 of each black and white sensitive chip 2130 is directly to be imaged, without being similar to the colored sense A certain number of pixels 1130 need to be constituted an imaging unit to carry out color image information synthesis operation by optical chip 110. Based on this photosensitive speciality, the black and white sensitive chip 210 can be under the premise of ensuring imaging, 2130 size of unit pixel 1130 size of unit pixel of the relatively described color sensitive chip 110 can be contracted by, to realize the reduction second photosensitive core The purpose of chip size.

More particularly, such as Fig. 4 and as shown in figure 5, existing color sensitive chip 210P, unit pixel size base This is in 1.0*1.0um or more, and 2130 size of unit pixel of the black and white sensitive chip 210 can be lower than 1.0*1.0um, example Such as 0.8*0.8um, 0.9*0.9um etc..That is, when second camera module 20 second sensitive chip 21 from When existing color sensitive chip 210P replaces with the black and white sensitive chip 210, the size of second sensitive chip 21 can phase To being reduced, thus second optical lens 22 and second sensitive chip 21 of second camera module 20 it Between relative distance can reduce, to reduce the whole height of the array camera module.

As shown in figure 5, working as the area of second sensitive chip 21, when especially imaging region reduces, ambient light passes through Optical path needed for second optical lens 22 exposes to the correspondence photosensitive region of second sensitive chip 21 can be contracted Subtract (h1-h2), so that the overall height dimension of the array camera module can effectively be reduced.Also, work as second light When learning the diminution of the corresponding imaging region of camera lens 22, the off-axis aberration of second optical lens 22 influences smaller.At the same time, (such as 0.6 visual field) position to evaluate certain field range of lens imaging ability can be closer to the described second photosensitive core The center of piece 21, so that the absolute size of the field angle of second optical lens 22 can also be reduced, further to drop Low lens design difficulty.It is also understood that under same quality requirement, for smaller chip (second sensitive chip 21) or for smaller imaging surface, the size of camera lens (second optical lens 21) can be smaller, as shown in Figure 4.It should be appreciated that , distance h1 between attached drawing 4 and attached second optical lens 22P shown in fig. 5 and second sensitive chip 21P with The distance between second optical lens 22 and second sensitive chip 21 h2, only illustrate, to show when described second When the size of sensitive chip 21 reduces, the distance between second optical lens 22 and second sensitive chip 21 can quilts Reduction and, when the size of second sensitive chip 21 is reduced, second optical lens 22 compares existing length Burnt optical lens, overall dimensions can be contracted by, so that the overall dimensions of the array camera module can further reduce Technology may and technical effect.

Further, since the black and white sensitive chip 210 is not provided with the color filter layer 112, such as Bayer filter, Therefore, the light for being radiated to second sensitive chip 21 does not filter reduction by the color filter layer 112, and still has There is relatively high luminous intensity.Therefore, even if light-inletting quantity is insufficient, but can be stronger photosensitive by the black and white sensitive chip 210 Performance is as making up, so that still having relatively high light and shade pair by 20 acquired image of the second camera module Than degree information.That is, when to be configured as a black and white photosensitive for second sensitive chip 21 of second camera module 20 When chip 210, the array camera module has relatively that preferably dark-state shoots performance, thus even if shooting in the dark state, institute The visual effect for stating array camera module still and having " optical zoom " of relatively high quality, it is more existing without being similar to The focal length camera module is closed in array camera module selection with " optical zoom " function.

It is noted that those skilled in the art will be appreciated that, " optical zoom " times of so-called array camera module Rate, depending between the equivalent focal length f1 of first camera module 10 and the equivalent focal length f2 of second camera module 20 Relativeness.The existing array camera module with " optical zoom " function, " optical zoom " multiplying power will not usually surpass 2 times are crossed, which is because, second camera shooting need to be promoted when wanting to promote " optical zoom " multiplying power of array camera module The equivalent focal length f2 of mould group 20.However, the promotion of the equivalent focal length f2 of second camera module 20, it is meant that described second The height dimension of second optical lens 22 of camera module 20 need to be elongated, this is undoubtedly not suitable for array camera module ruler The very little demand that need to reduce.

However, in the preferred embodiment of the invention, second sensitive chip 21 of second camera module 20 It is implemented as a black and white sensitive chip 210, compared to color sensitive chip, the size of the black and white sensitive chip 210 is with respect to quilt Reduction, so that second optical lens 22 of second camera module 20 can be more adjacent to second sensitive chip 21.Therefore, in the present invention, " optical zoom " multiplying power of the array camera module is settable more than 2 times, such as 3 times, only Need to meet by second optical lens 22 brought by the black and white sensitive chip 210 height dimension reduction (including The reduction of the 22 oneself height size of installation deflection (h1-h2) and second optical lens of second optical lens 22 Amount) it is greater than the length incrementss caused since the equivalent focal length f2 of second optical lens 22 need to be promoted.

It should also be mentioned that image is able to carry out " nothing in order to during subsequent progress imagery optical zoom Damage zoom ", that is, during optical zoom, the clarity of the image keeps higher level.Preferably, second sense 21 unit field angle pixel density of optical chip is greater than or equal to the pixel of first sensitive chip 11., it will be appreciated that working as institute When stating the second 21 pixel with higher of sensitive chip, second sensitive chip 21 is able to achieve the function of similar " super-sampling ", Thus during carrying out optical zoom, even if the image is correspondingly handled, such as cuts or amplifies etc., the figure As being able to maintain relatively high clarity level, to realize the technical effect of " lossless zoom " in visual effect.However, This imagination is but difficult to carry out, which is because, when should in the existing array camera module with " optical zoom " function When the pixel of second sensitive chip 21P need to increase, the size of second sensitive chip 210P need to be increase accordingly, to correspond to Second optical lens 22P visual field corner characteristics of second camera module 20P, the bottom surface of optical lens 22P need far from this Two sensitive chip 21P, meanwhile, the size of second optical lens 22P itself also needs to expand, this all will lead to array camera shooting The whole height of mould group is further promoted.

Correspondingly, in the preferred embodiment of the invention, second sensitive chip 21 uses black and white sensitive chip 210 substitution color sensitive chip 210P.Just as previously mentioned, by the black and white sensitive chip 210 photosensitive imaging feature, institute 2130 size of unit pixel for stating black and white sensitive chip 210 compares the unit pixel 2130P area of color sensitive chip 210P, It can be contracted by.Therefore, in the preferred embodiment of invention, the pixel of second sensitive chip 21 can be suitably promoted, simultaneously The size for meeting second sensitive chip 21 is less than the size that the second sensitive chip 21P is color sensitive chip 210P, with So that, on the one hand, the size of second sensitive chip 21 can be contracted by, to reduce the installation of second optical lens 22 Highly；On the other hand, the pixel of second sensitive chip 21 is suitably promoted, so that at subsequent progress optical zoom During reason, opposite it can be maintained by the measured target image of second camera module 20 relatively distant place collected Higher clarity is horizontal.Figuratively, it is the technical solution of black and white sensitive chip by second sensitive chip 21, gives The more design parameter selections of designer have been given, have preferably been put down so that it can be obtained in imaging effect and terms of overall dimensions Weighing apparatus.

Further, in the preferred embodiment of the invention, the array camera module is that integral type array images mould Group.As shown in fig. 6, first camera module 10 and second camera module 20 can conductively be installed on same circuit board 30, to be that first camera module 10 and second camera module 20 provide a location and installation by the circuit board 30 Basal plane.During subsequent installation calibration, basal plane set by the circuit board 30 can be used as calibration first camera shooting The basal plane parallel with 20 optical axis of the second camera module of mould group 10.
