Patent number: 10523850Abstract: A camera device is packaged inside an external shell of an electronic apparatus. The external shell has an opening. The camera device has a transparent plate, a part of which is adjacent to the opening of the external shell. The transparent plate forms an accommodating space for accommodating other components of the camera device. Thus, the dust can be prevented from falling into a shutter blade room of the camera device. The camera device also includes a shutter blade, a driver, and a plate. The plate has an aperture, and the aperture of the camera device is defined thereby. The aperture of the plate is completely pervious to light when the shutter blade is at a first position, and the aperture of the plate is partially pervious to light when the shutter blade is at a second position, thereby changing the aperture of the camera device.Type: GrantFiled: December 30, 2016Date of Patent: December 31, 2019Assignees: SINTAI OPTICAL (SHENZHEN) CO., LTD., ASIA OPTICAL CO., INC.Inventors: Chien-hung Chen, Hsi-ling Chang, Chun-hung Huang
