图像稳定的数码成像 Image stabilization digital imaging

技术领域 Technical Field

本发明涉及一种电子设备,其包括: -图像传感器, The present invention relates to an electronic device, comprising: - an image sensor,

-光学器件,用于在该图像传感器上形成图像, - Optical device for forming an image on the image sensor,

-检测器,用于结合成像过程来检测以该设备为目标的、由外部源所引起的移动效果,以及 - Detectors for imaging procedures to detect binding to the target device, the mobile effect caused by an external source, and

--光学图像稳定器单元,被设置用于致动至少一部分该光学器件,从而补偿所检测到的、由外部源引起的移动效果。 - Optical image stabilizer unit, is provided for actuating at least a portion of the optical device, thereby compensating for the detected moving effect caused by an external source.

此外,本发明还涉及方法、光学图像稳定器单元以及用于致动所述单元的对应的计算机产品。 Further, the present invention also relates to a method, an optical image stabilizer unit and means for actuating the corresponding computer product unit.

背景技术 Background

在数码成像设备的用户例如通过高分辨率/变焦因子、低灵敏度传感器、长曝光时间(夜间拍摄)和通过轻重量设备(例如移动电话)来执行成像过程的特定情况中,手的抖动可能很容易地引起模糊、离焦的图像。 In the image forming apparatus, for example, users of digital high-resolution / zoom factor, the low sensitivity of the sensor, a long exposure time (night shot) and through lightweight devices (e.g., mobile phone) to perform a particular case of the imaging process, the hand shake can be easily lead to blur, defocused images. 这种效果可以利用图像稳定器应用(或防抖动) This effect can be applied using the image stabilizer (or anti-shake)

来避免。 To avoid.

基本上,有三种方法来解决上述问题:l)在拍摄期间使用针对相机的刚性固定设施(例如三脚架),2)增加相机设备的重量,从而抖动具有较小影响,或3)使用内置稳定化系统。 Basically, there are three ways to solve the problem: l) use for the camera during shooting rigid fixed facilities (such as a tripod), 2) increase the weight of the camera device, which has a smaller effect of jitter, or 3) the use of the built-in stabilization system. 由于使用三脚架并不总是可能的,并且增加重量不太切合实际,所以稳定化是用于包括相机单元的小型移动产品的较好特征。 The use of a tripod is not always possible, and increase the weight impractical, so characteristic for stabilization is preferably small mobile products including the camera unit.

图像稳定化在商业上可获得的移动相机中尚未广泛实现,但在中距数码静物相机(例如松下型号[l])中已经存在。 Image stabilization in commercially available mobile camera has not been widely implemented, but in the distance from the digital still camera (such as the Panasonic model [l]) already exists. 在相机中,可以通过移动光学器件(镜头)或传感器来实现平衡效果。 In the camera, balancing effect can be achieved by moving the optics (lens) or sensors. 在这两点中,移动镜头在尺寸方面产生更切合实际的实现。 In these two points, move the lens to produce a more realistic implementation in size.

欧洲专利申请EP-0 253 375提供了一种在其中图像传感器移动的解决方案。 European Patent Application EP-0 253 375 provided an image sensor in which a mobile solution. 然而,这种解决方案不适用于商业数码相机或移动电话。 However, this solution does not apply to commercial digital camera or mobile phone. 该解决方案的目标是集成电路的掩码匹配。 The objective of the solution is an integrated circuit mask match. 这些应用要求一种选项来校正固态图像传感器的倾斜。 These applications require an option to correct the inclination of the solid-state image sensor.

欧洲专利申请EP-0 572 976提供了一种在其中部分光学器件移动的解决方案。 European Patent Application EP-0 572 976 provides a portion of the optical device in which mobile solutions. 这是基于结合成像处理而检测到的由外部源所引起的响应来执行的。 This is based on a combination of imaging is detected by the response caused by an external source performed. 然而,该公开文件并未给出执行该光学器件致动的光学图像稳定器的技术实现。 However, this disclosure does not give Execution Technology Optical Image Stabilizer The optical device is actuated.

此外,现有技术解决方案必须具有单独的设置来检测校正镜头相对于传感器的位置。 In addition, the prior art solutions must have separate settings to detecting and correcting lens relative to the position sensor. 为了对此进行测量,必须设置一些特定的检测器来对此进行测量。 In order to measure this, you must set some specific detector to measure this. 这复杂化了光学图像稳定器单元的实现。 This complicates the realization of an optical image stabilizer unit.

通过为每一个致动部件17.1、 17.2提供若干止动器19.1-19.5, 获得了当考虑便携式设备的使用性质时单元14的安全和可靠的实现。 By actuating member for every 17.1 17.2 19.1-19.5 provides several stopper obtained when considering the nature of the use of portable devices to achieve safe and reliable unit 14. 当标准移动电话从1.5 m高度坠落时,甚至可以发生约10G的外部力。 When a standard mobile phone fall from 1.5 m height, even the external force of about 10G can occur. 当坠落发生时,对镜头元件12.1周围的每四个侧具有影响的限制件19.1-19.5控制镜头12.1的移动。 Limiting member when the fall occurred, it has an impact on each of the four sides of the lens elements around 12.1 19.1-19.5 12.1 panning control. 这些被用于防止由于浮动镜头12.1到周围机构(致动器、开关)所引起的沖击力。 These are used to prevent the impact force due to the floating lens 12.1 peripheral mechanism (actuator, switch) caused.

致动部件17.1、 17.2可以设置为形成具有几乎矩形形状的元件,其中从该元件中一个主要侧被移除。 Actuating member 17.1, 17.2 can be set to form an element having a nearly rectangular shape, wherein one side is removed from the main element. 在该实施方式中,浮动镜头12.1 In this embodiment, the floating lens 12.1

处于两个金属(例如弯曲线或穿孔的片状金属)制成的U形部分17.1、 17.2之间。 In two metal (e.g., curved lines or perforated sheet metal) U-shaped portion 17.1 formed, between 17.2. U形致动部件17.1、 17.2的压电致动器16.1、 16.2设置在与该被移除侧相反的一侧。 U-shaped actuating member 17.1, 17.2 of the piezoelectric actuator 16.1, 16.2 disposed on one side, and the opposite side is removed in the. 两个压电致动器16.1、 16.2安装在柔性印刷电路FP.C上。 Two piezoelectric actuators 16.1, 16.2 mounted on a flexible printed circuit FP.C. 镜头12.1可以附接到臂17.1、 17.2的相反的主要侧上。 Lens 12.1 may be attached to the arm 17.1, 17.2 on the opposite side of the main. 在臂17.1、 17.2中,可以具有弯曲,其将单元14的内部结构纳入考虑,并且还支持镜头12.1的受控移动路径,而不对内部机构产生损害。 The arms 17.1, 17.2, and may have a curved, its internal structure unit 14 will be taken into account, and also supports the controlled movement path of the lens 12.1, without causing damage to the internal mechanism.

臂17.1、 17.2相对于彼此以下列方式进行设置:当一个臂17.1 通过压电致动器16.1来移动镜头12.1的时候,镜头12.1在另一臂】7.2之间自由并无级地滑动。 Arm 17.1, 17.2 relative to each other in the following manner settings: When one arm 17.1 through 16.1, when the piezoelectric actuator to move the lens 12.1, shot 12.1 slidably no level ground between the other arm] 7.2. 因此,将臂17.1、 17.2相对于彼此进行精确匹配还控制了镜头12.1的移动。 Therefore, the arm 17.1, 17.2 relative to each other an exact match also control panning 12.1. 臂17.1、 17.2的功能是除了一个维度中致动力的介质之外,还控制镜头12.1在另一维度中的路径,即形成镜头12.1的线性导引。 Arm 17.1, 17.2 functionality is in addition to an actuation force of medium dimension, but also controls the lens 12.1 path in another dimension, namely the formation of the lens 12.1 linear guide. 也还简化了机械构造。 Also simplifies the mechanical structure.
