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

技术领域 FIELD

[0001] 本发明涉及一种图像稳定的数码成像电子设备,其包括: [0001] The present invention relates to an electronic image stabilization of a digital image forming apparatus, comprising:

[0002]-图像传感器, [0002] - an image sensor,

[0003]-光学器件,用于在该图像传感器上形成图像, [0003] - an optical device for forming an image on the image sensor,

[0004]-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 [0004] - a detector for the imaging process to detect binding to the target device, the movement effect caused by an external source, and

[0005]-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。 [0005] - an optical image stabilizer unit, is provided for actuating at least a portion of the optical device, thereby compensating for the detected, moving the effect caused by an external source.

[0006] 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。 [0006] Further, the present invention also relates to a method, an optical image stabilizer unit and means for actuating said units corresponding computer product.

背景技术 BACKGROUND

[0007] 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。 [0007] In the user through the digital image forming apparatus such as a high-resolution / zoom factor, the particular case of the low sensitivity of the sensor, a long exposure time (night shot) and is performed by a light weight device (e.g. a mobile telephone) in the imaging process, the hand Jitter may easily cause fog, out of focus images. 这种效果可以利用图像稳定器应用(或防抖动)来避免。 This effect can be applied using the image stabilizer (or anti-shake) to avoid.

[0008] 基本上,有三种方法来解决上述问题:1)在拍摄期间使用针对相机的刚性固定设施(例如三脚架),幻增加相机设备的重量,从而抖动具有较小影响,或幻使用内置稳定化系统。 [0008] Basically, there are three ways to solve the problem: 1) use for the camera during the filming of a rigid fixed facilities (such as a tripod), increase the weight of the magic camera equipment, which has a smaller influence of jitter, or use the built-stable Magic 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。 Due to the use of a tripod is not always possible, and increase the weight not practical, so a better stabilization is characteristic for small mobile devices including the camera unit.

[0009] 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[1])中已经存在。 [0009] Image stabilization commercially available mobile camera has not been widely implemented, but in the distance from the digital still camera (e.g. Panasonic model [1]) 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, the effect can be achieved by moving the balance 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, and move the lens to produce more realistic to achieve in size.

[0010] 欧洲专利申请EP-O 253 375提供了一种在其中图像传感器移动的解决方案。 [0010] European Patent Application EP-O 253 375 is 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 is unsuitable for 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.

[0011] 欧洲专利申请EP-O 572 976提供了一种在其中部分光学器件移动的解决方案。 [0011] European Patent Application EP-O 572 976 provides a portion of the optical device in which a mobile solution. 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 the combination of imaging is detected by the response arising from an external source to perform. 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 document does not give a public execution technology Optical Image Stabilizer The optics of actuation.

[0012] 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。 [0012] In addition, prior art solutions must have a separate correcting lens disposed to detect the relative 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。 For this measurement, 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 Optical Image Stabilizer unit.

[0055] 用于检测以设备10为目标的、由外部源所引起的移动效果的检测器可以包括例如一个或多个小陀螺仪传感器元件,其可以互相分离。 [0055] In the device for detecting a target 10, caused by an external source effect movement detector may comprise for example one or more small gyro sensor element, which can be separated from each other. 图1中给出了此类陀螺仪的一个示例及其检测维度。 Figure 1 shows an example of such a dimension and its detection gyro. 可能的陀螺仪的一些商用示例是Murata ENC-03系列和Epson XV3500-CB。 Some examples of possible commercial gyroscope is Murata ENC-03 series and Epson XV3500-CB. 这些陀螺仪被设置为生成指示所检测移动效果的数据,更具体而言,例如它的量、速度和方向。 These gyroscopes are set to generate data indicative of the detected movement effect, more specifically, for example, its amount, speed and direction.

[0056] 设备10还配备有处理器CPU,这在上面进行了描述。 [0056] The apparatus 10 is also equipped with a processor CPU, which are described above. 处理器CPU被设置用于生成用于光学图像稳定器单元14的致动信号。 CPU processor is configured to generate a signal for actuating the optical image stabilizer unit 14. 该控制信号生成是基于数据来执行的,即基于关于由外部源所引起的以及由一个或多个小型分离陀螺仪元件所生成的移动效果的信息。 The control signal generation is performed based on the data, which is based on the information on movement effect caused by an external source and separated by one or more small gyro element of the generated. 程序代码装置31. 7可以负责与此相关的操作。 Program code means 31.7 may be responsible for operations associated with this. 该信息经由在图1中描述的数据线传输到处理器CPU。 This information is transmitted to the processor CPU through a data line as described in Figure 1. 然后,通过使用该信号来控制压电致动器,通过使用该致动器,镜头移动到相反方向以校正图像。 Then, by using this signal to control the piezoelectric actuator by using the actuator, the lens is moved to the opposite direction to correct the image. 程序代码装置31. 4应用陀螺仪所提供的数据。 Program code means 31.4 gyroscope data provided.

[0057] 外壳15. 1,15. 2还可以配备有限制结构19. 1-19. 5。 [0057] housing 15. 1,15. 2 may also be provided with a confinement structure 19. 1-19. 5. 该限制件现在处于与致动器相对的一侧。 The restricting member is now in the opposite side of the actuator. 然而,该限制件的设置方式为其在每个方向上限制臂的移动。 However, the restricting member is set up in each direction for limiting movement of the arm. 这意味着限制致动部件17. 1,17.2的移动。 This means that the actuating member limiting movement of 17. 1,17.2. 该限制结构19. 1-19. 5为设置到致动部件17. 1,17.2的光学器件12. 1定义极端位置。 The limit structure 19. 1-19. 5 is set to the actuating member 17. 1,17.2 12.1 optics define extreme positions. 致动臂现在从这些限制结构19. 1,19. 2,19. 4,19. 5之间至少一个它们的开口端延伸。 At least one actuating arm is now extending from the open end thereof between the confinement structure 19. 1,19. 2,19. 4,19. 5. 另一方面,在其极端位置,臂的主要侧抵住结构。 On the other hand, in its extreme position, against the main structure of the side arm. 对结构的抵靠发生在宽长度上,其也支持了光学器件12. 1。 Of the abutment structure occurs over a wide length, which also supports the optics 12.1.

[0058] 通过为每一个致动部件17. 1、17. 2提供若干止动器,获得了当考虑便携式设备的使用性质时光学图像稳定器单元14的安全和可靠的实现。 [0058] By providing a number of stopper for each actuating member 17. 1,17. 2, obtained when considering the nature of the portable device using an optical image stabilizer to achieve safe and reliable unit 14. 当标准移动电话从1. 5m高度坠落时,甚至可以发生约IOG的外部力。 When a standard mobile phone from 1. 5m height of fall, and even about IOG external force can occur. 当坠落发生时,对镜头元件周围的每四个侧具有影响的限制件控制镜头的移动。 When a fall occurs, the four sides of each lens element surrounding the impact of the movement restriction member has control of the lens. 这些被用于防止由于浮动镜头到周围机构(致动器、开关)所引起的冲击力。 These are used to prevent the lens to float around the mechanism (actuator, switch) caused by the impact force.

[0059] 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。 [0059] actuating member 17. 1,17. 2 may be arranged to form a member having an almost rectangular shape in which one side is removed from the main element. 在该实施方式中,浮动镜头处于两个金属(例如弯曲线或穿孔的片状金属)制成的U形部分之间。 In this embodiment, the lens is floating between two metal U-shaped portion (e.g., a curved line or perforated sheet metal) made. U形致动部件的压电致动器设置在与该被移除侧相反的一侧。 U-shaped actuating member piezo actuator is provided at the opposite side is removed. 两个压电致动器安装在柔性印刷电路FPC上。 Two piezoelectric actuators mounted on the flexible printed circuit FPC. 镜头可以附接到臂的相反的主要侧上。 Lens can be attached to the side opposite to the main arm. 在臂中,可以具有弯曲,其将光学图像稳定器单元14的内部结构纳入考虑,并且还支持镜头的受控移动路径,而不对内部机构产生损害。 In the arm, may have a curved, its internal structure of the optical image stabilizer unit 14 is taken into account, and also supports the controlled movement path of the lens, without creating damage to the internal mechanism. [0060] 臂相对于彼此以下列方式进行设置:当一个臂通过压电致动器来移动镜头的时候,镜头在另一臂之间自由并无级地滑动。 [0060] arm with respect to each other set in the following manner: the lens does not slide freely through the stage to the time when one of the arms of the piezoelectric actuator to move the lens between the other arm. 因此,将臂相对于彼此进行精确匹配还控制了镜头的移动。 Thus, the arm relative to each other precisely match the movement of the lens is also controlled. 臂的功能是除了一个维度中致动力的介质之外,还控制镜头在另一维度中的路径,即形成镜头的线性导引。 Function is to arm the actuation force in addition to a dimension medium, but also controls the lens in the path of another dimension, i.e. form a linear guide lens. 也还简化了机械构造。 It also simplifies the mechanical structure.

[0061] 存在商用可用的压电致动器可用于本发明的目的,其可以实现所需的线性移动。 [0061] the presence of commercially available piezoelectric actuator can be used for purposes of this invention, which can achieve the desired linear movement. SIDM型(平滑冲击驱动机制)可以被与此相关地提及作为压电机制操作原理的示例。 SIDM type (smooth shocks drive mechanism) may be relevant to refer to this as an example of the principle of operation of piezoelectric mechanism. 通过利用合适的电压信号(以及电压方向/波形图案)来操作该压电部件(或其中发生变形的其他致动器元件),镜头沿X和Y轴在滑动件之间自由移动。 By using an appropriate voltage signal (voltage direction and / waveform pattern) to operate the piezoelectric member (or other actuator element is deformed), the lens along the X and Y-axis between the sliding member is free to move. 线路Ll和L2提供的信号依赖于所检测到的移动。 Line Ll and L2 signals supplied depends on the movement detected. 在每个维度中检测到的移动量可以有所不同,因此信号相互之间也可以具有不同的测量。 The detected amount of movement in each dimension may vary, so that the signal may have different measuring each other. 有鉴于此,臂相对彼此独立移动。 In view of this, the arms move independently relative to each other. 在压电陶瓷致动器的情况下,这些变形也将发生。 In the case of the piezoelectric ceramic actuator, such modifications will also occur. 然而,在压电应用的情况下膨胀和压缩/收缩事件可能很小,并且由于此原因还可以具有一些合适的传输机制,通过这些传输机制,这些很小的步骤(step)串链到一起,从而实现镜头的期望的移动效果。 However, in the case of expansion and contraction of the piezoelectric applications / contraction events may be small, and for this reason may also have some suitable transport mechanism, through which the transport mechanism, these small steps (step) is chained together, in order to achieve the desired movement of the lens effect.

[0062] 致动器的形式可以是,臂处于它们之间或之中,通常,与它们相连接。 [0062] The actuator may take the form, the arm is between or among them, generally, they are attached. 而且,臂自身可以拥有变形特性。 Moreover, the arm itself can have deformation characteristics. 当收缩和膨胀发生时,致动器迫使轴发生移动。 When the contraction and expansion occurs, the actuator forces the shaft moves. 可以对致动器的内表面和臂的外表面进行处理,从而如果在它们之间应用有这种轴向设置,则减少它们之间的摩擦。 Can outer surface of the actuator arm and the inner surface of the processing, so that if there is applied between them This axial setting, reducing the friction between them. 这对于实现无级和连续移动是重要的。 This is important for achieving the stepless and continuous movement. 致动器以及臂之间的机械连接推动臂以相对于致动器进行线性移动。 The actuator and the mechanical connection between the arms push arm with respect to the linear actuator to move.

[0063] 当根据本发明的光学图像稳定器单元14加电时,两个机械开关18. 1,18.2对镜头进行定位,并定义基准点。 [0063] When the unit is powered up, two mechanical switches 18. 1,18.2 lens optical image stabilizer according to the present invention 14 is positioned, and define the reference point. 此后,单独的一个或多个陀螺仪元件用于测量以设备10为目标的振动的方向和水平,基于此,处理器CPU控制稳定效果。 Thereafter, one or more separate elements gyroscope for measuring device 10 to the target direction and the horizontal vibration, based on this, the processor CPU controls the stabilizing effect.
