Description

成像装置及方法 Image forming apparatus and method

技术领域 FIELD

[0001] 本发明涉及成像技术领域,尤其涉及一种成像装置及成像方法。 [0001] The present invention relates to the technical field of imaging and more particularly relates to an imaging apparatus and an imaging method.

背景技术 Background technique

[0002] 移动设备的屏幕大小与便携性一直是一对难以解决的矛盾,虽然屏幕分辨率可以做到很高,但由于屏幕尺寸限制,正常情况下无法显示很多信息。 [0002] screen size and portability of mobile devices has been difficult to solve a pair of contradictions, though high screen resolution can be done, but because of the screen size limitations, under normal circumstances can not display a lot of information. 如果可以让用户以更近距离的使用移动设备,则可以显示更加丰富的信息。 If you can allow the user to a closer using a mobile device, it can display richer information.

[0003] 然而日常生活中,对于远视眼以及屈光度正常的用户来说,一般难以看清很近距离的物体;对于近视眼用户来说,又经常会面临一个问题,就是当不带矫正眼镜时,左右眼都可以分别看清很近的物体(例如手机屏幕),但却无法将左右眼的图像会聚;而戴上矫正眼镜时,又无法看清很近的物体了(如公开号为JP2007219462A的日本专利申请中图2_3所示)。 For myopia users, but also often faced with a problem, that is, when without corrective glasses; [0003] However, in daily life, as well as for hyperopia diopter normal users, it is generally difficult to see objects up close left and right eyes can see close objects, respectively (e.g., cell phone screen), but not the left and right eye images converge; while wearing corrective spectacles, and can not see the object very close (e.g., Publication No. JP2007219462A Japanese Patent application shown in FIG 2_3). 虽然,已有可调镜片通过改变自身的焦距等成像参数(如对近视眼将镜片屈光度调整到O甚至正数,对远视眼将镜片屈光度调整至比看较远处时更大的正数),可以解决看清很近物体的问题,但由于双眼视线会聚角度过大而无法会聚,导致这种情况下用户只能用一只眼睛来观看,严重影响用户体验。 Although existing adjustable lens focal length by altering its imaging parameters (e.g., adjust the diopter myopia lenses or even to positive O, adjust diopter of hyperopia the lenses to a greater distance than when the ratio of positive to see) can solve the problem see close objects, but because of your eyes in the convergence angle is too large to be converged, causing the user can only use one eye to watch such a case, seriously affecting the user experience.

[0004] 上述公开号为JP2007219462A的日本专利申请中虽然记载了通过在普通屈光矫正眼镜上设置一棱镜装置,来帮助两眼视线的会聚(见该专利申请的图2-4所示的实例),但是其使用很不方便,用户体验不佳。 Examples shown in Japanese Patent Application [0004] Publication No. JP2007219462A above although the described means by providing a prism in the ordinary refractive glasses to help two eyes converging (see FIGS. 2-4 of this patent application ), but it is very easy to use, poor user experience.

[0005] 如果可以实时检测用户眼睛注视点的位置,并根据注视点位置来自适应的调整眼镜镜片的光轴,使得用户注视的物体可以会聚在用户能够舒适观看的位置,则可以解决上述问题,提闻用户体验。 [0005] If real-time detection of the position of the user's eye gaze point, and adjusted according to the gaze point position from the optical axis of the spectacle lens adaptation, so that the user can watch an object can be converged at a comfortable viewing position of the user, you can solve the above problems, Wen put the user experience.

[0115] 本发明实施例中的所述可调透镜模块110通过改变自身的结构姿态、或位置来改变光线的传播方式(包括传播方向),其可以为由单片成像参数可调的透镜构成、也可以为由多片透镜构成的透镜组构成、或者还可以为包括透镜和其它光学器件的光学系统。 [0115] The embodiment of the adjustable lens module 110 by the posture change their structure, location, or to change the mode of transmission of light (including the direction of propagation) embodiment of the present invention, which can be imaged by a single piece lenses with adjustable parameters , by a lens group may be composed of a plurality of lenses configured, it can also include a lens or other optical devices and optical systems.

[0117] 在本发明实施例的一种可能的实施方式中,所述透镜调节模块的内部结构可以调节;这里的内部结构包括:内部的分子结构或排列发生了变化,内部包括的多个部分之间的位置或者比重发生了变化等等; Molecular structure or arrangement of a plurality of portions of the interior of the changes, comprising inside: the internal structure herein comprises; [0117] In one possible embodiment by way of example of the present invention, the internal structure of the lens module may be adjusted adjusted position or change in specific gravity between the like;

[0118] 或者,所述透镜调节模块的外部结构可以调节;这里的外部结构主要是指透镜调节模块的形状等; [0118] Alternatively, the outer structure of the lens adjustment module may be adjusted; herein refers to the external shape of the module structure mainly like a lens adjustment;

[0119] 或者,所述透镜调节模块的内部结构和外部结构都可以调节。 [0119] Alternatively, the inner and outer structures lens conditioning module can be adjusted.

[0120] 例如:在本发明实施例的一些可能的实施方式中,所述可调透镜模块110可以包括电子可调透镜,如美国公开号为US20070211207A1和US4572616A的专利中公布的液体或液晶透镜,通过对透镜中的液体或液晶进行控制,从而快速改变透镜的形状、折射率等成像参数。 [0120] For example: In some possible embodiments of the present invention by way of example, the tunable lens 110 may include an electronic module adjustable lens as described in US Publication No. liquid crystal lens or patent US20070211207A1 and published in US4572616A, by liquid or liquid crystal lens is controlled to quickly change the shape of the lens, refractive index imaging parameters. 对于将本发明的装置应用在眼镜等便携可穿戴设备上的场合来说,采用单片的电子可调透镜作为所述可调透镜模块110可以使得装置的体积更小、重量更轻,便于携带;并且将所述电子可调透镜应用于眼镜上的方式已经有了商业上的应用,如Pixeloptics公司推出的Empower电子可调焦眼镜。 The apparatus for application of the invention in spectacles and other portable apparatus wearable on occasions, a single-chip electronic adjustable lens as the adjustable lens module 110 may cause the volume of the device is smaller, lighter, portable ; and the electron lens is applied to an adjustable manner on the glasses have commercial applications, such as the Empower Pixeloptics introduced electronically focus spectacles.

[0121] 此外,例如在一些现有技术中,可以在透镜的镜片中包含至少两种折射率不同、不会相互混合的介质,通过改变所述至少两种不同介质的分界面的形状,也可以改变所述可调透镜模块的光轴方向等成像参数。 [0121] Further, for example, in some prior art, the lens may comprise at least two lenses of different refractive index, the medium is not mixed with each other, at least by changing the shape of the interface of the two different media, also the tunable parameters may be changed optical axis direction of the imaging lens module and the like.

[0122] 因此,如图4所示,在一种可能的实施方式中,所述眼镜410的镜片411通过将其形状调节成楔形的方式来调整其光轴方向,眼睛420的视线经过所述镜片411后被调整。 [0122] Thus, as shown in FIG. 4, in one possible embodiment, the spectacle lens 410, 411 to adjust its optical axis adjusted by the shape of wedge-shaped manner, through said eye gaze 420 lens 411 after adjustment. 或者,在其它实施方式中,还可以通过将镜片411的形状调节成图3所示(但不是通过机械的调节)来调整其光轴方向。 Alternatively, in other embodiments, it can also be adjusted to the shape of the lens 411 shown in FIG. 3 (but not by a mechanical adjustment) to adjust its optical axis. 除了上述图3和图4所示的两种形状外,所述镜片411还有可能为光轴方向可调节的双凸透镜、透光平板等等可以起到折光作用的形状,通过调节,可以使得其对眼睛的视线方向起到向内会聚或向外扩散的折光作用。 In addition to the two shapes shown in FIGS. 3 and 4 above, the lens 411 may also be adjusted to the optical axis direction of the lenticular lens, light transmissive flat plate like shape can play the role of refraction by adjusting can be made play a role in its refractive inwardly converging or outward diffusion of the eye gaze direction.

[0124] 此外,由于用户在看近处物体时,还有可能存在需要对晶状体等眼镜光学系统进行比较费力的调节,改变眼睛光学系统的屈光度才能看清近处的物体,或者甚至是已经到达调节的极限了,但还是不能看清近处的物体等问题,因此优选地,还因可以根据上述的会聚参数对可调透镜模块的屈光参数进行调节,以使得用户除了可以比较舒适的会聚视线夕卜,还可以比较舒适的聚焦在近距离的对象上。 [0124] Further, since the user when looking at near objects, there may be a need for an optical system such as lens eyeglasses compared laborious adjustment to change the refractive power of the optical system eye to see close objects, or even has been reached adjusting the limit, but still can not see near objects and other problems, it is preferable, it is also because the parameters can be adjusted refractive adjustable lens module according to the above-described parameters converge, so that the user in addition to converge more comfortable Bu Xi line of sight, but also more comfortable focusing on close subjects. 即,在本发明实施例的一种可能的实施方式中,所述可调透镜模块的成像参数还包括可调透镜模块的屈光参数。 That is, in one possible embodiment of the present invention, in an embodiment, the adjustable parameters of the imaging lens module further comprises a tunable parameters refractive lens module. 这里的屈光参数也包括可调透镜模块中透镜的曲度以及折射率等参数。 Here parameters include refractive adjustable lens module and the refractive index of the lens curvature and other parameters. 所述屈光参数的调节也包括在上面所述对可调透镜模块进行成像参数调节的过程中(例如,透镜的曲度为透镜的外部结构,透镜的折射率为透镜的内部结构),此处不再赘述。 The adjustment of the refractive parameter also includes adjustable lens module to perform the above process of adjusting imaging parameters (e.g., external curvature of the lens structure of the lens, the lens is a refractive index of the internal structure of the lens), this at not repeat them.

[0125] 此外,当所述可调透镜模块包括多片透镜时,可以其中至少一片透镜的光轴方向可调、至少一片透镜的屈光度可调(这里也可以是同一片透镜的光轴方向和屈光度同时可调)。 [0125] Further, when the adjustable lens module includes a plurality of lenses, which may be at least one adjustable optical axis direction of the lens, at least one adjustable diopter lens (here may be the same optical axis direction of a lens and Meanwhile diopter adjustable). 或者,也可在实现改变可调透镜模块光轴方向参数的基础上,对多片透镜之间的相对位置进行调整来改变所述可调透镜模块的屈光参数。 Alternatively, the lens module may be adjustable based on parameters the optical axis direction to achieve changes in the relative positions between the plurality of lenses is adjusted to change the adjustable parameter refractive lens module.

[0186] 微型摄像头610,其作用与图5b实施方式中记载的图像采集设备相同,为了不影响用户正常观看对象的视线,其被设置于眼镜200右外侧; [0186] miniature camera 610, its role and image capture device of FIG. 5b embodiment described in the same manner, in order not to influence the normal line of sight viewing objects, which is provided on the right outer glasses 200;

[0187] 第一分光镜620,其作用与图5b实施方式中记载的第一分光单元相同,以一定倾角设置于眼睛200注视方向和摄像头610入射方向的交点处,透射观察对象进入眼睛200的光以及反射眼睛到摄像头610的光; [0187] The first dichroic mirror 620, which is the same effect with the first embodiment of FIG. 5b spectroscopic unit described embodiment, the constant angle 200 is provided at the intersection of the eye gaze direction and the incident direction of the camera 610, the transmittance of the observation target 200 entering the eye light and the reflected light to the camera eye 610;

[0188] 焦距可调透镜630,其作用与图5b实施方式中记载的焦距可调透镜相同,位于所述第一分光镜620和摄像头610之间,实时进行焦距值的调整,使得在某个焦距值时,所述摄像头610能够拍到眼底最清晰的图像。 [0188] adjustable focus lens 630, the focal length of its role and FIG. 5b embodiment described in the same tunable lens, between the first dichroic mirror 620 and the camera 610 is located, the real-time adjustment of the focus value, in such a when the focus value, the fundus camera 610 can take the sharpest image.

[0189] 在本实施方式中,所述图像处理设备在图6中未表示出,其功能与图5b所示的图像处理设备相同。 [0189] In the present embodiment, the image processing apparatus is not shown in FIG. 6, FIG. 5b which functions the same as in the image processing apparatus shown in FIG.

[0190] 由于一般情况下,眼底的亮度不够,因此,最好对眼底进行照明,在本实施方式中,通过一个发光源640来对眼底进行照明。 [0190] Since generally, the luminance of the fundus insufficient, therefore, it is preferable to illuminate the fundus, in the present embodiment, the fundus 640 is illuminated by a light source. 为了不影响用户的体验,这里优选的发光源640为眼睛不可见光,优选对眼睛200影响不大并且摄像头610又比较敏感的近红外光发光源。 In order not to affect user experience, where the light emitting source 640 preferably invisible for the eyes, preferably has little effect on the eye 200 and the camera 610 and the near-infrared sensitive light emitting source.

[0191] 在本实施方式中,所述发光源640位于右侧的眼镜架外侧,因此需要通过一个第二分光镜650与所述第一分光镜620 —起完成所述发光源640发出的光到眼底的传递。 [0191] In the present embodiment, the light emitting source 640 is located outside the right side of the spectacle frame, is required by a second dichroic mirror 650 and the first dichroic mirror 620-- 640 emitted from the light source to complete the hair to transfer the fundus. 本实施方式中,所述第二分光镜650又位于摄像头610的入射面之前,因此其还需要透射眼底到第二分光镜650的光。 In the present embodiment, the second dichroic mirror 650 and is positioned before the incident surface of the camera 610, so it also needs to transmit the light to the fundus of the second beam splitter 650.

[0192] 可以看出,在本实施方式中,为了提高用户体验和提高摄像头610的采集清晰度,所述第一分光镜620优选地可以具有对红外反射率高、对可见光透射率高的特性。 [0192] As can be seen, in the present embodiment, in order to improve the user experience and improve the clarity captured by the camera 610, the first dichroic mirror 620 preferably have the characteristics of high reflectance for infrared high visible light transmittance . 例如可以在第一分光镜620朝向眼睛200的一侧设置红外反射膜实现上述特性。 For example, a first dichroic mirror 620 toward the eye 200 side is provided to achieve the above characteristic infrared reflective film.

[0193] 由图6可以看出,由于在本实施方式中,所述对焦点距离检测单元600位于眼镜600的镜片远离眼睛200的一侧,因此进行眼睛光学参数进行计算时,可以将镜片也看成是眼睛的一部分,此时不需要知道镜片的光学特性。 [0193] As can be seen from Figure 6, since in the present embodiment, the focus point is located spectacle detection unit 600 from the side away from the eye lenses 600, 200, so that an eye optical parameter calculation, the lens may also be as a part of the eye, you do not need to know at this time the optical characteristics of the lens.

[0194] 在本发明实施例的其它实施方式中,所述对焦点距离检测单元600可能位于眼镜400的镜片靠近眼睛200的一侧,此时,需要预先得到镜片的光学特性参数,并在计算对焦点距离时,考虑镜片的影响因素。 [0194] In other embodiments of the present invention by way of example, the 600 may be located on the focal length detection unit 400 of lens eyeglasses 200 side close to the eyes, in which case, it is necessary to obtain the optical parameters of the lens, and in the calculation when the focus distance, consider the impact factor of the lens.

[0195] 发光源发出的光通过第二分光镜650的反射、焦距可调透镜630的投射、以及第一分光镜620的反射后再透过眼镜400的镜片进入用户眼睛,并最终到达眼底的视网膜上;摄像头610经过所述第一分光镜620、焦距可调透镜630以及第二分光镜650构成的光路透过眼睛200的瞳孔拍摄到眼底的图像。 [0195] Hair tunable light source of the projection lens 630 passes through the second dichroic mirror 650 is reflected by the focal length, the first dichroic mirror 620 and reflected into the eye of a user and then transmitted through the lens eyeglasses 400, and ultimately to the fundus the retina; camera 610 through the first dichroic mirror 620, adjustable focus lens 630 and a second dichroic mirror 650 constituting an optical path of the fundus image captured through the pupil of the eye 200.

[0196] 如图7所示为本发明实施例的另一种实施方式对焦点距离检测单元700的结构示意图。 Another embodiment by way of example [0196] As shown in FIG. 7 of the present invention, a schematic structural diagram of the focal length detection unit 700. 由图7可以看出,本实施方式与图6所示的实施方式相似,包括微型摄像头710、第二分光镜720、焦距可调透镜730,不同之处在于,在本实施方式中的投射装置740为投射光斑图案的投射装置740,并且通过一个曲面分光镜750作为曲面分光单元取代了图6实施方式中的第一分光镜。 As it can be seen from Figure 7, similar to the embodiment shown in the embodiment of FIG. 6, comprising a miniature camera 710, a second beam splitter 720, adjustable focus lens 730, except that, in the projection device according to the present embodiment 740 is a projection 740 projected speckle pattern, and a dichroic mirror surface 750 replaces the first beam splitter splitting unit embodiment of FIG. 6 by a curved surface.
