Abstract: An artificial muscle structure has an electro-active polymer (EAP) layer having a frusto-conical shape and whose tip has an opening formed therein for use as a camera variable aperture. First, second and third electrode segments are formed on a rear face of the EAP layer. The second segment is positioned in a gap between the first and third segments so as to be electrically isolated from the first and third segments. The second segment has an opening formed therein that is aligned with the opening in the EAP layer. A complementary electrode is formed on a front face of the EAP layer. Other embodiments are also described.

Abstract: A camera includes a pulse transmitter for transmitting at a transmit time through an aperture and along an optical path to a target a coherent electromagnetic ranging pulse at a first wavelength range outside the visible spectrum. In some embodiments, the camera includes a reflected pulse detector for receiving a reflected electromagnetic pulse reflected by the target back along the optical path and through the aperture at a detect time subsequent to the transmit time. In some embodiments, the camera includes a shutter positioned for shielding the pulse detector from at least transmit time to an intermediate time between the transmit time and the detect time. In some embodiments, the shutter includes a layer of semiconductor material placed in the optical path at a point between the target and the detector.

Abstract: Some embodiments include methods for correcting optical alignment of components in a camera module for a multifunction device. In some embodiments, components of a camera module for use in a multifunction device are assembled on a test station. Some embodiments include a method that includes capturing a single test image, calculating from the spatial frequency response data an optical tilt between the optical axis of a lens and an optical axis of the image sensor of the camera module, and mechanically adjusting an alignment of the lens and the optical axis of the image sensor of the camera module to reduce the optical tilt. In some embodiments, the capturing is performed using the components of the camera module, and the single test image contains visually encoded spatial frequency response data for characterizing the components of the camera module.

Abstract: A digital image captured by a digital camera module is scaled to a smaller size, and separately horizontal direction filtered and vertical direction filtered using one-dimensional spatial filters. The horizontal direction filtered image and the vertical direction filtered image are combined, wherein edge regions and corner regions of the combined filtered image are created differently than its middle region. The combined filtered image is then thresholded selected pixels of the thresholded image are marked as a blemish region. Other embodiments are also described and claimed.
