An imaging device 100 includes an imaging element 103, a mirror 102, a lens 101, and a mirror tilt actuator 110. The imaging element 103 images subject light that is reflected light from a subject. The mirror 102 reflects the subject light, and makes the subject light incident on the imaging element 103. The lens 101 collects the subject light on the mirror 102. The mirror tilt actuator 110 drives the mirror 102 so as to change an optical axis of the lens OAL. The optical axis of the lens OAL is an optical axis to be incident on the central part C of the imaging element 103 in the subject light exited from the lens 101.

  • Patent number: 10091425
    Abstract: An image stabilization mechanism for a camera is provided. The mechanism comprises a movement sensor capable of sensing motion of the camera, an element in an optical path of the camera, a ball and a plate acting as a bearing allowing for the element to move in a plane orthogonal to the optical path, an actuator mechanism capable of moving the element in the plane, and a processor configured to control the actuator to move the element as a response to motion of the camera as detected by the movement sensor, thereby stabilizing images from the camera. Furthermore, the processor further is configured to move the element along a secondary motion path so as to distribute wear on the plate created by the ball, and the processor is further capable of compensating for an image shift created by the secondary motion path by other means for shifting the image.

    Abstract: A small format factor camera system for mobile devices that provides improved image quality when using accessory lenses. The system may detect an accessory lens attached to the camera, either via sensing technology or by analyzing captured images. The system may analyze image data to determine current alignment (e.g., optical axis alignment, spacing, and/or tilt) of the accessory lens relative to the camera lens, and may shift the camera lens on one or more axes using a mechanical or optical actuator, for example to align the camera lens optical axis with the accessory lens optical axis. The system may also determine optical characteristics of the accessory lens, either via sensing technology or by analyzing captured images, and may apply one or more image processing functions to images captured using the accessory lens according to the determined optical characteristics of the accessory lens.
