It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As described above, consumer proposes more in image quality, coverage and the dark scape shooting effect to photographic device While high requirement, the need of the lightening miniaturization (thickness especially on certain dimension) to photographic device of electronic product Ask also more strong.It is integrated with the photographic device of three groups of optical lens groups this application provides a kind of, it can be in unobvious increase In the case where photographic device thickness, there is better shooting scene adaptability.
Fig. 1 and Fig. 2 is to show the schematic diagram of the photographic device of the application embodiment.Referring to Figures 1 and 2, camera shooting dress Setting includes: focal length lens group A, and focal length lens group A has effective focal length fA；Wide angle lens group B, wide angle lens group B have effective Focal length fB；And the maximum angle of half field-of view of extrawide angle lens group C, extrawide angle lens group C are greater than 55 °.Focal length lens group A, wide-angle Lens group B and extrawide angle lens group C is set to the same side and the f of photographic deviceA/fB>7.Photographic device energy provided by the present application The shooting that high definition details is enough realized by focal length lens group A cooperates focal length lens group A expansion can be clear by wide angle lens group B The still life range of imaging, and shoot by extrawide angle lens group C the panorama of wider Wide-angle.It is provided by the present application this to match The photographic device for having three groups of optical lens groups can either meet the requirement of photographic device miniaturization, and be able to ascend shooting body It tests.At the same time, the effective focal length of focal length lens group A and wide angle lens group B, which meets above-mentioned numberical range, can guarantee camera shooting dress It sets with sufficiently large zoom magnification.This configuration can effectively guarantee can blur-free imaging the depth of field.In addition, adjusting ultra-wide angle The aberration mistake that there is lens group C suitable field angle peripheral field can be avoided while improving photographic device imaging image height Greatly, facilitate to preferably keep the high feature of photographic device image quality, thus energy when being effectively guaranteed photographic device imaging Enough there is open field range and ensure that user has good shooting effect experience sense.
As shown in Figure 1, focal length lens group A, wide angle lens group B and extrawide angle lens group C can be in a lateral edges of photographic device Vertical direction arrangement.In addition, can also be as shown in Fig. 2, focal length lens group A, wide angle lens group B and extrawide angle lens group C can take the photograph As the side of device is arranged in the horizontal direction.Focal length lens group A, wide angle lens group B and extrawide angle lens group C can be respectively to objects It is imaged.For example, focal length lens group A can be equipped with the first sensitive chip matched with focal length lens group A, wide angle lens group B Can equipped with the second sensitive chip matched with wide angle lens group B, and extrawide angle lens group C can equipped with extrawide angle lens The third sensitive chip of group C pairing.First sensitive chip can be black and white sensitive chip, such as MONO (Monochrome) core Piece.It can use the light and shade intensity of black and white sensitive chip perceptual image.In addition, the second sensitive chip and third sensitive chip can be with It is color sensitive chip, such as RGB (Red-Green-Blue) chip or RGBW (Red-Green-Blue-White) chip. It can use color sensitive chip to restore form and aspect and coloration.
In addition, focal length lens group A, wide angle lens group B and the image of extrawide angle lens group C shooting can synthesize composite diagram Picture, to be provided simultaneously with the characteristic of the big depth of field, high-resolution and ultra-wide angle.In addition, can also be obtained in conjunction with the collocation of above-mentioned sensitive chip Take the clear image of high contrast and color high-fidelity.
It can be five chip lens groups according to the focal length lens group of the application embodiment.Focal length lens group from object side at Image side sequentially includes: the first lens of focal length group, has focal power；The second lens of focal length group have negative power；Focal length group third Lens have focal power；The 4th lens of focal length group have positive light coke；And the 5th lens of focal length group, there is focal power.Root Spherical aberration, astigmatism and the coma of the lens group can be effectively reduced according to the focal length lens group that above-mentioned configuration obtains, realize it is good at Image quality amount.
As can be referring to being described in detail following figure 3 and Fig. 4 according to the focal length lens group of the application embodiment latent Prestige formula lens group.For the periscopic lens group, optical path extends not along single direction.For example, focal length lens group Optical axis can change 90 ° by focal length group the first lens rear direction.By the way that such periscopic lens group is arranged, can increase Thickness of the lens group in the incident direction of light is not increased while adding the thickness of the lens stacked direction of the lens group.Therefore, Periscopic lens group can be very good to take into account miniaturization and long-focus, avoid conventional focal length lens group with longer dimension Problem.According to the application embodiment, the effective focal length fA of focal length lens group can meet: 18mm < fA < 20mm.
