摘要： A camera shutter mechanism for covering and exposing an imaging sensor array is disclosed. The camera shutter mechanism includes a rotary motor, a crank mechanism, a cover, a guide, and a drive circuit. The rotary motor is coupled to the crank mechanism to rotate the crank mechanism about a central axis. The cover is coupled to the crank mechanism at a point away from the central axis. The drive circuit controls the rotary motor so that the cover moves back and forth repeatedly in a substantially linear motion along the guide between a shutter closed position and a shutter open position over the imaging sensor array. Other embodiments are also described and claimed.

摘要： A method performed by an electronic camera in flash mode is as follows. A scene ambient lighting indication is obtained. An integration time interval and a flash pulse-on time interval for taking a picture is then set. The set integration time interval is shorter when the indication is bright than when the indication is dark; and the set flash pulse-on time interval is longer when the indication is bright than when the indication is dark. An image is captured using the set integration time interval and the set flash pulse-on time interval in accordance with an electronic rolling shutter (ERS). Other embodiments are also described and claimed.

摘要： A camera includes a lens arranged to focus an image on an image sensor and a touch sensitive visual display for freely selecting two or more regions of interest on a live preview image by touch input. An image processor is coupled to the image sensor and the touch sensitive visual display. The image processor displays the live preview image according to the image focused on the image sensor by the lens. The image processor further receives the selection the regions of interest and controls acquisition of the image from the image sensor based on the characteristics of the image in regions that correspond to at least two of the regions of interest on the live preview image. The image processor may optimize sharpness and/or exposure of the image in at least two of the regions of interest. The image processor may track movement of the selected regions of interest.

摘要： An image capture sharpening subsystem for a digital camera includes a capture sharpening processor and a memory that stores values for a capture sharpening amount. The values for the capture sharpening amount are a function of position on an image sensor of the digital camera. The capture sharpening processor receives a first value for a pixel in an image captured by the image sensor and a position value for the pixel on the image sensor. The capture sharpening processor determines a pixel sharpening amount from the values for the capture sharpening amount stored in the first memory according to the position value. The capture sharpening processor applies a capture sharpening process to the pixel to provide a second value for the pixel according to the pixel sharpening amount and stores the second value in a second memory that provides a sharpened version of the image captured by the image sensor.

摘要： A method and system for effecting adaptive autofocusing, such as for a camera, are disclosed. The method can comprise obtaining focusing information, such as historic focusing actuator current or voltage information or focusing lens position information, storing the focusing information, and subsequently using the focusing information to facilitate a determination of a best position of a focusing lens during a focusing process. The use of such focusing information can result in a better choice for the next focusing lens position to be tested, such that the focusing process can be performed more rapidly. The use of such focusing information can also mitigate the undesirable effects of production variations and/or component wear.
