Embodiment Construction

[0033] The dust removal system of the present invention is applicable to the vibration and dust removal of a light-transmitting object (such as the glass of an image sensor or a camera lens) of a camera device. The following uses an interchangeable-lens camera as an example, but the scope of actual application is not limited thereto.

[0034] see figure 1, which is a block diagram of the dust removal system of the present invention. As shown in the figure, the dust removal system 10 of the present invention is suitable for a camera device 1 , which includes a vibration generation module 101 , a vibration detection unit 102 , a comparison unit 103 and a control unit 104 . The vibration generation module 101 includes a vibration element 1011, and the vibration element 1011 is driven to generate a vibration 10111 to remove dust; the vibration element 1011 can be a piezoelectric element, which is arranged on one side of a light-transmitting object 11 of the imaging device 1, wher...

Abstract

The invention discloses a dust removal system, a photographic device and a dust vibration method thereof. The dust removal system comprises a vibration generating module, a vibration detecting unit, a comparing unit and a control unit. A vibration element of the vibration generating module is disposed on a light transmitting object of the photographic device. The vibrating element is driven to generate a vibration so as to remove dust. The vibration detecting unit is disposed on the light transmitting object to detect a vibration amplitude variation when the light transmitting object vibrates. The vibration amplitude variation is converted into a corresponding electrical signal so as to continuously output a feedback signal. When the comparing unit determines that the feedback signal exceeds a threshold value, a control signal is generated. The control unit controls the vibration generating module according to the control signal, and enables the vibration element to generate vibrations correspondingly to remove dust. Thus, according to the invention, the amplitude of the object can be reliably obtained so that more precise control and adjustment of vibrations are further made.

Description

technical field [0001] The invention relates to a dust removal system, an imaging device and a vibration dust removal method thereof, in particular to a dust removal system, an imaging device and a method for directly detecting the amplitude of a light-transmitting object and then determining the vibration amplitude generated by a vibration generation module for vibration dust removal. Its vibration dust removal method. Background technique [0002] With the advent of the digital age and the continuous advancement of technology, the sales price of interchangeable-lens digital cameras, such as digital single-eye cameras (DSLRs), is becoming more and more popular, so that interchangeable-lens digital cameras have become almost everyone's favorite. A must-have 3C product. The advantage of the interchangeable-lens digital camera is that its image quality is excellent, and it can be replaced by a camera lens with an appropriate focal length according to the needs of the camera. ...
