摘要： Systems and methods described herein can be used to improve camera modules (e.g., camera components), particularly when the camera lens depth of focus is very small. Improvement of a camera with a small depth of focus is particularly important in various applications, such as in cameras used in autonomous navigation (e.g., advanced driver assistance systems (ADAS) and autonomous vehicle (AV) systems).

摘要： A system for indicating sharpness of images is provided. The system includes a computer, which is connected to a measuring machine for an object to be laid thereon for measurement. The measuring machine has a Z axis, on which a charged coupled device (CCD), an optical lens and a lever are installed. The computer includes: an image capturing card which connects the computer and the CCD for capturing a series of images from the CCD, transmitting the series of images to an image measuring module to calculate a sharpness value of each image; and an image focusing indicator for displaying sharpness of the series of images by a graph when a user operates the lever to focus the optical lens on the object. A related method is also provided.

摘要： A control system for an objective of the camera, in particular a film camera, includes one or several drive units for automatically positioning at least one lens ring, e.g., for adjusting the focus position, the opening of the iris diaphragm and/or the focal length. The drive units can be used to adjust the lens ring(s) to a predefined set position. A device coupled to each of the lens rings determines the actual position of the lens rings relative to the objective and converts this position into a measuring output signal.
