[0021]请参阅图1,本发明实施方式的控制方法,用于控制成像装置对焦。 [0021] Referring to FIG. 1, a control method of the embodiment of the present invention, an image forming apparatus for controlling the focus. 其中,成像装置包括对焦镜头及显示器。 Wherein the image forming apparatus includes a focus lens and a display.

[0022]控制方法包括以下步骤: [0022] The control method comprises the steps of:

[0023] S10:根据对焦镜头的对焦范围、图像传感器的尺寸及物距信息确定最小画幅。 [0023] S10: The information from the focusing range of the focus lens, the image sensor is determined and physical size of the smallest format.

[0025] S30:驱动显示器显示预览图像。 [0025] S30: drive the display to display a preview image.

[0026]请参阅图2,本发明实施方式的控制装置100包括确定模块10、处理模块20及驱动模块30。 [0026] Referring to FIG. 2, the control device 100 embodiments of the present invention includes a determining module 10, a processing module 20 and the driving module 30. 作为例子,本发明实施方式的控制方法可以由本发明实施方式的控制装置100实现,并可应用于电子装置1000,电子装置1000可以包括控制装置100及成像装置200。 As an example, a control method of the embodiment of the present invention may be implemented by the control device 100 embodiments of the present invention can be applied to electronic device 1000, the electronic device 100 and the image forming apparatus 1000 may include a control apparatus 200.

[0027]其中,本发明实施方式的控制方法的步骤SlO可以由确定模块10实现,步骤S20可以由处理模块20实现,而步骤S30可以由驱动模块30实现。 [0027] wherein the step of the control method of embodiment of the present invention may be SlO determined by the module 10 implemented by the processing in step S20 module 20 may be implemented, and the step S30 may be implemented by the drive module 30. 也即是说,确定模块10用于根据对焦镜头的对焦范围、图像传感器的尺寸及物距信息确定最小画幅。 That is, the pitch information for determining module 10 according to the size and physical focusing range of the focus lens, an image sensor to determine the minimum frame. 处理模块20用于处理图像传感器在成像装置200对焦过程中输出的图像以裁剪出最小画幅对应的部分作为预览图像。 The processing module 20 for processing an image output from the image sensor in the image forming apparatus 200 focus process to cut out a portion corresponding to the minimum frame as a preview image. 而驱动模块30用于驱动显示器显示预览图像。 And driving module for driving the display 30 displays a preview image.

[0028]对焦范围也即是成像装置能够清晰成像的范围。 [0028] The focus range that is, the image forming apparatus capable of clear image range. 在对焦过程中,由于推动镜头,会导致视场角的变化,从而导致预览画面的场景发生变化。 During focusing, since it pushes the lens, result in a change of the viewing angle, resulting in a preview scene changes. 本发明实施方式的控制方法通过确定最小画幅,然后对图像传感器输出的图像以最小画幅裁剪出相应部分作为预览图像提供给用户进行预览。 Control method according to the present embodiment of the invention corresponding to the minimum frame portion cut by determining the minimum format, and the image output from the image sensor as a preview image to the user for preview.

[0029]请参阅图3,在对焦过程中,当物距一定时,对焦镜头通过移动来获取合适的像距完成对焦。 [0029] Referring to FIG 3, during focusing, when a certain object distance, the focusing lens to obtain proper focus is achieved by moving the image distance. 随着镜头的移动,视场角将发生变化,其大小的可以根据图像传感器尺寸及对焦镜头与图像传感器的距离来确定,当物距一定时,视场角的大小与对焦镜头与图像传感器间的距离成反比。 With the movement of the lens, the angle of view changes will occur, its size may be determined according to the size of the distance image sensor and the focus lens of the image sensor, when the object distance is constant, the size of the viewing angle and the focus lens and the image sensor between It is inversely proportional to the distance. 如图示,在某一对焦场景中,对焦镜头的极限位置分别为Pl及P2,并分别对应最大视场角Θ1及最小视场角Θ2,通常在成像时,图像传感器以全尺寸输出图像,因此根据图像传感器的尺寸及视场角可以获知当前图像传感器能够成像的场景范围。 The limit position shown in a focus area, the focus lens Pl and P2, respectively, and the corresponding maximum angle Θ1 and Θ2, respectively, the minimum angle of view, typically at the time of imaging, image sensor to output a full-size image, Thus, according to the size and angle of view of the image sensor may be learned scope of the current scene can be imaged to the image sensor. 显然,当镜头位于Pl及P2之间的其他位置时,图像传感器以全尺寸输出的预览图像的场景变化将在场景范围SI至S2之间。 Clearly, other positions when the lens is located between the Pl and P2, SI image sensor in the scene to scene change range of the preview image to the full size between output S2. 场景范围SI对应最大视场角01的图像传感器的成像尺寸AI即为最小画幅。 Scene SI range corresponds to the maximum angle of view of the image sensor 01 is the minimum image size AI format. 也即是说,当场景范围在SI至S2之间变化时,相对应的图像传感器成像的画幅也将在全尺寸与最小画幅Al间变化。 That is, when the range of the scene change between SI to S2, an image sensor corresponding to the imaged frame will also vary between full frame size and the minimum Al. 因此,始终以最小画幅Al对图像传感器在对焦过成中输出的图像进行裁剪并进行显示,则用户预览到的画面将始终不变。 Thus, always the smallest of the Al frame in the image sensor to focus the image through the output of the cropping and displayed, the user of the preview screen will be always the same.

[0030]综上所述,本发明实施方式的控制方法、控制装置100及电子装置1000,根据成像镜头的相关参数确定最小画幅,并通过对图像传感器输出的图像进行处理使得显示器在始终显示最小画幅对应部分的图像作为预览图像,改善用户视觉体验。 [0030] In summary, the embodiment of the control method according to the present invention, the control apparatus 100 and the electronic device 1000, the minimum format is determined according to the relevant parameters of the imaging lens, and processed by an image output from the image sensor such that the display always shows the minimum corresponding portions of the image frame as a preview image, to improve the visual experience of the user.

[0031]在某些实施方式中,电子装置1000可以是手机或平板电脑等具有拍照功能的电子终端。 [0031] In certain embodiments, the electronic device 1000 may be a mobile phone or a tablet computer terminal having an electronic camera function. 而成像装置200包括前置或/及后置相机。 The imaging apparatus 200 includes the front or / and rear camera.

[0032] 可以理解,电子装置1000包括但不限于本实施方式的示例。 [0032] It will be appreciated, the electronic device 1000 include but are not limited to the exemplary embodiment of the present embodiment.

[0033]在某些实施方式中,控制方法包括: [0033] In certain embodiments, the control method comprising:

[0034]控制成像装置200采用反差式对焦方式、相位对焦方式或激光对焦方式对焦。 [0034] Control 200 employs contrast AF mode type image forming apparatus, phase focusing mode or focus mode of the laser focus.

[0035]可以理解,无论采用何种对焦方式,均需要通过对焦镜头的移动来实现对焦,因此,在对焦过程中均会产生由于视场角变化导致的场景范围的变化。 [0035] It will be appreciated, regardless of the focus way, are required to achieve the focus by moving the focus lens, and therefore, during focusing range will produce a scene change due to viewing angle variations.

[0036] 在某些实施方式中,成像装置200包括激光测距装置,激光测距装置用于获取物距 [0036] In certain embodiments, the image forming apparatus 200 includes a laser distance measuring device, a laser distance measuring device for obtaining an object distance

ί目息O ί mesh information O

[0037]相应地,对于相位对焦模式,则可通过图像传感器的相位侦测像素获取左右像素波形,并根据左右像素波形的相位差获取物距信息。 [0037] Accordingly, the phase focus mode, left and right pixels may be acquired by the phase detector waveform of pixel image sensor, and acquires the phase difference object distance information about the pixel waveform.

[0038]请再次参阅图3,在某些实施方式中,最小画幅通过以下条件式确定: [0038] Referring to FIG. 3 again, in some embodiments, the minimum format is determined by the following condition:

[0039] h = 2*fl*tan(a/2); [0039] h = 2 * fl * tan (a / 2);

[0040]其中,W为所述最小画幅,fl为所述成像镜头的最小成像物距,a为当前视场角。 [0040] where, W is the smallest format, fl is the imaging lens imaging the minimum object distance, a is the current viewing angle.

[0041]如图示,对焦镜头位于Pl位置时,对焦镜头与图像传感器的距离为fl,对应的视场角ΘI = 2arctan(H/fl),其中H为图像传感器对角线长度的一半。 [0041] As illustrated, the focus lens is located at position Pl, the focus lens from the image sensor as fl, corresponding to a half angle of field ΘI = 2arctan (H / fl), where H is the diagonal length of the image sensor. 相应地,对焦镜头位于P2位置时,焦镜头与图像传感器的距离为f 2,对应的视场角Θ2 = 2arctan(H/f 2)。 Accordingly, the focus lens is located at a position P2, the lens focal distance and the image sensor is f 2, corresponding to the field angle Θ2 = 2arctan (H / f 2).

[0042]由此可以得到H' =Fl*tan(01/2),h' =F2*tan(02/2)。 [0042] can be obtained by H '= Fl * tan (01/2), h' = F2 * tan (02/2).

[0043]最小画幅Al的视场角a = 2arctan(h'/Fl)。 [0043] The field format of Al smallest angle a = 2arctan (h '/ Fl).

[0044] 最小画幅Al的对角线的一半h = 2*fl*tan(a/2)。 Half [0044] the smallest diagonal format of Al h = 2 * fl * tan (a / 2).

[0045]在对图像传感器输出的预览图像进行裁剪时,根据获取的最小画幅的对角线长度及图像传感器的尺寸进行裁剪。 [0045] When the preview image in the image sensor output cut, cut according to the size of the smallest frame length and obtain a diagonal of the image sensor. 使得所裁剪出的图像然按原比例显示。 The cut-out so that the ratio of the original image and then displayed.

[0046]本发明实施方式的控制装置100及电子装置1000未展开的其他部分,可参以上实施方式的控制方法的对应部分,在此不再详细展开。 The control device [0046] 100 according to the present embodiment of the present invention and other parts of the electronic device 1000 is not deployed, the corresponding portion of a reference method for controlling the above embodiments, the details will not be deployed.
