[0052] 为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。 [0052] For the above-described objects, features and advantages of the invention more apparent, the accompanying drawings and the following specific embodiments of the present invention will be further described in detail.

[0053] 本发明的图像采集方法,应用于采用液体透镜的图像采集设备。 [0053] The image acquisition method according to the present invention, is applied to the image capture device using a liquid lens.

[0054] 液体透镜的原理是,将液体作为透镜,通过改变液体的曲率来改变焦距。 Principle [0054] Liquid lens is a liquid lens, the focal length is changed by changing the curvature of the liquid. 现在较为成熟的液体透镜是利用介质上电润湿(EWOD)原理的可变焦光透镜。 Now it is the more mature the liquid lens using electrowetting medium (the EWOD) the principles of the variable focus optical lens. 它可以通过外加电压改变液滴的形状,进而改变其焦距。 It can change the shape of the droplet by the applied voltage, thereby changing its focal length.

[0055] 图1为本发明的图像采集方法实施例1的流程图。 1 a flowchart of a method of image acquisition [0055] FIG. 1 embodiment of the present invention. 如图1所示,所述方法可以包括: As shown in FIG 1, the method may comprise:

[0056] 步骤101:确定对于所述液体透镜的调节参数信息; [0056] Step 101: determining parameter adjustment information for said liquid lens;

[0057] 所述调节参数信息至少可以包括两方面的信息。 [0057] The adjustment parameter information may include information on at least two aspects. 一方面的信息可以表示,将所述液体透镜划分为子透镜的个数;另一方面的信息可以表示,将所述液体透镜划分成的各个子透镜的焦距。 Information may indicate one hand, the liquid lens is divided into a number of sub lenses; may represent another aspect of the information, a focal length of the liquid lens is divided into respective sub-lens.

[0058] 步骤102:按照所述调节参数信息,对所述液体透镜进行调节; [0058] Step 102: according to the regulation parameter information, the liquid lens is adjusted;

[0059] 对所述液体透镜的调节,可以包括将所述液体透镜划分为多个子透镜,还可以包括调节所述液体透镜划分成的各个子透镜的焦距。 [0059] The adjustment of the liquid lens, the liquid lens may comprise a plurality of divided sub-lens, a focal length further may include adjusting the liquid lens is divided into respective sub-lens.

[0060] 步骤103:米用调节后的液体透镜米集图像。 [0060] Step 103: the liquid lens meter set by the image adjustment meters.

[0061] 当所述液体透镜被划分为多个子透镜后,可以采用多个子透镜对同一取景范围内的景物进行图像采集。 [0061] When the liquid lens is divided into a plurality of sub-lenses, can view the scene in the same range image acquisition using a plurality of sub lenses. 不同的子透镜的焦距可以是不同的,所以,采用多个子透镜可以获取到同一取景范围内不同景深的图像信息。 Sub-lens different focal lengths may be different, therefore, a plurality of sub-lens image information can be acquired in the same range of different depths of field of view.

[0062] 另一方面,划分后的同一个子透镜,在对同一取景范围内的景物进行图像采集时,还可以先后采用不同的焦距进行多次图像采集。 [0062] On the other hand, the same sub-division of the lens, at the time of image acquisition in the same scene of the shooting range, and also has a plurality of times using different image capture focal length. 例如,将液体透镜划分为四个子透镜后,每个子透镜可以采用四种不同的焦距获取四次图像信息,这样就可以获取同一取景范围内16种不同景深的图像信息。 For example, after the liquid lens is divided into four sub-lens, each of the sub lens may be four different focal lengths acquired image information four times, so that you can get 16 different depth of image information within the same range finder.

[0063] 本实施例中,通过在图像采集设备中采用液体透镜,在进行图像采集前,确定对于所述液体透镜的调节参数信息;按照所述调节参数信息,对所述液体透镜进行调节;采用调节后的液体透镜采集图像;能够对透镜进行调节,使得图像采集设备在取景范围中的物体焦距过大或过小时,也能够得到清晰的图像,从而扩展图像采集设备的适用范围。 [0063] In this embodiment, by using a liquid lens in the image pickup apparatus, before performing the image acquisition, the parameter information is determined for the regulation of the liquid lens; parameter according to the adjustment information, for adjusting the liquid lens; using a liquid lens adjusting the captured image; lens can be adjusted so that the focal length of the object in the image pickup apparatus in the shooting range is too large or too small, a clear image can be obtained, thereby extending the scope of the image capture device.

[0064] 图2为本发明的图像采集方法实施例2的流程图。 Example 2 a flowchart of a method of image acquisition [0064] FIG. 2 embodiment of the present invention. 如图2所示,所述方法可以包括: The method shown in FIG. 2 may include:

[0065] 步骤201:确定将所述液体透镜划分为子透镜的个数; [0065] Step 201: determining the liquid lens is divided into a number of sub-lens;

[0066] 可以根据用户的设置,将所述液体透镜划分为预设数目的子透镜,也可以根据用户对于其他参数的设置,或者取景范围的图像信息,自动确定将所述液体透镜划分为子透镜的个数。 [0066] according to the user settings, the liquid lens is divided into a preset number of sub-lenses, may be provided for the other parameters, or a shooting range of the image information, automatically determining the liquid lens is divided into sub-user the number of lenses.

[0067] 例如,用户设置的预设数目为4,那么就可以将所述液体透镜划分为4个子透镜。 [0067] For example, a user set predetermined number is 4, then the liquid lens can be divided into four sub-lens. 又例如,用户设置的最低成像分辨率为400*400像素,液体透镜的总面积为1600*1600像素,那么就可以将所述液体透镜划分为16个子透镜,以使得每个子透镜生成的图像信息的分辨率不低于400*400像素。 As another example, the user set the minimum imaging resolution of 400 * 400 pixels, the total area of ​​the liquid lens is 1600 * 1600 pixels, the liquid lens can be divided into 16 sub-lenses, so that each sub-lens image information generated the resolution is not less than 400 * 400 pixels. 又例如,取景范围内的景物的焦距范围为Ι-lOOm,每个子透镜能够清晰成像的焦距范围为10m,那么,就可以将所述液体透镜划分为10个子透镜。 As another example, the focal length range of the scene within the range finder is Ι-lOOm, each sub-lens can be clear image focus range is 10m, then, the liquid lens can be divided into 10 sub-lenses.

[0068] 步骤202:通过调节施加于液体透镜两侧的电场宽度,将所述液体透镜划分为多个子透镜,划分后的子透镜个数与确定的将所述液体透镜划分为子透镜的个数相等。 [0068] Step 202: By adjusting the electric field applied to the width of the liquid sides of the lens, the liquid lens is divided into a plurality of sub lenses, the number of the divided sub-lens and the liquid lens to the determined sub-lens is divided into two equal numbers.

[0069] 液体透镜两侧具有电场。 [0069] The liquid lens has an electric field on both sides. 电场强度高的区域,液体透镜的厚度较大,电场强度低的区域,液体透镜的厚度较小。 Region of high electric field strength, the thickness of the liquid lens is large, the region of low electric field strength, the smaller the thickness of the liquid lens. 因此,对液体透镜进行划分时,可以将各个子透镜的交界处的电场强度调低,将各个子透镜的中心区域的电场强度调高。 Thus, when the liquid lens is divided, the electric field intensity may be the junction of the respective sub lens down, the electric field intensity of each sub-central area of ​​the lens increase.

[0070] 步骤203:采用多个子透镜对同一取景范围内的景物成像,得到多幅不同焦距的图像信息;其中,一个子透镜对应于一幅图像信息; [0070] Step 203: the scene using a plurality of sub lenses of the imaging range in the same view, the image information obtained plurality of different focal lengths; wherein a sub-lens corresponding to an image information;

[0071] 由于将所述液体透镜划分成的各个子透镜的焦距是不同的,所以采用多个子透镜对同一取景范围内的景物成像,可以得到多幅不同焦距的图像信息。 [0071] Since the focal length of the liquid lens is divided into respective sub-lenses are different, so the use of a plurality of sub-lenses for imaging the scene in the same shooting range, the image information can be obtained plurality of different focal lengths. 本实施例中,划分后的子透镜只需采用单一焦距对同一取景范围内的景物成像。 In the present embodiment, the divided sub-lens focal length only a single scene in the same imaging range finder. 因此,一个子透镜与一幅图像信息相对应。 Accordingly, a sub-lens and one corresponding to image information.

[0072] 步骤204:根据多幅所述图像信息,生成取景范围内的空间影像信息。 [0072] Step 204: The information of the plurality of images, the image information generation space within the shooting range.

[0073] 本步骤中,可以根据某一取景范围内的景物,生成取景范围内的空间影像信息。 [0073] In this step, according to a shooting range of the scene, the image information generation space within the shooting range. 采用本步骤生成的空间影像信息的文件,用户在浏览时,可以对实际显示的图像的景深进行调节,根据不同的景深,可以显示不同焦距的图像,从而使用户能够清晰的看到取景范围中的任意景物。 Spatial image information file generated in this step, the user while browsing, may be adjusted for depth image actually displayed, depending on the depth of field, can display images with different focal lengths, so that the user can clearly see the range finder any scene.

[0074] 本实施例中,通过将液体透镜划分为多个子透镜,采用各个子透镜对同一取景范围内的景物成像,得到多幅不同焦距的图像信息,根据多幅所述图像信息,生成取景范围内的空间影像信息,可以生成能够显示同一取景范围内的不同景深的景物的空间影像文件。 [0074] In this embodiment, the liquid lens is divided by a plurality of sub lenses, lenses for the respective sub-scene using the same imaging range finder, the image information obtained plurality of different focal lengths based on the plurality of image information, a viewfinder spatial image information range may be generated capable of displaying a scene different depths within the same space range finder image file.

[0079] 采用当前的液体透镜划分状态获取取景范围内的图像,根据图像中最清晰的区域所对应的焦距,确定景深。 [0079] The current state of the liquid lens is divided within the shooting range of the image acquisition, the image clearest areas corresponding to the focal length, depth of field is determined.

[0080] 图像中最清晰的区域与其他区域的锐度不同,清晰处的锐度较高。 [0080] The clearest image region and other regions of different sharpness, high sharpness at the clear. 因此,可以根据某一幅图像信息中锐度最大的区域,判断出该幅图像信息中,最清晰的区域是哪里。 Thus, according to a certain maximum sharpness of the image information in a region, it is determined that the image information of the web, where the clearest areas Yes. 当液体透镜被划分为多个子透镜时,可以分别获取每一幅图像中锐度最大的像素,然后对各个像素的锐度值进行比较,确定锐度最大的像素对应的图像,再确定产生该图像的子透镜的焦距,将该子透镜的焦距确定为取景范围的景深信息对应的焦距。 When the liquid lens is divided into a plurality of sub-lenses, respectively, may be acquired in each image pixel of maximum sharpness and sharpness values ​​of the respective pixels are compared to determine the maximum sharpness of the image corresponding to the pixel, and then generates the determined the focal length of the image sub-lens, the focal length of the lens is determined to be the sub-view range of the depth information corresponding to the focal length.

[0081] 确定将所述液体透镜划分成的各个子透镜的焦距的一个具体的例子可以是:取景范围的景深为Ι-lOOm,划分成的子透镜的个数为10个,就可以将子透镜的焦距范围分别确定为1-lOm, 10-20m, 20_30m…90_100m。 [0081] determining the liquid lens is divided into respective sub-lens focal length of a specific example may be: the depth of field range of the finder Ι-lOOm, divided into a number of sub-lenses 10, may be sub lens focal length range are determined as 1-lOm, 10-20m, 20_30m ... 90_100m.
