An LO clock signal generator includes a fundamental mixer for mixing a source clock signal with a divided version of the source clock signal. The LO clock signal generator also includes a harmonic mixer for mixing the source clock signal with a third harmonic of a divided version of the source clock signal.

In accordance with a first aspect of the present disclosure, a method for providing a code pattern which is readable by a sensor is conceived, the method comprising: defining a plurality of coding positions as a subset of positions in a two-dimensional matrix; including in said subset a plurality of positions which are diagonally adjacent to each other; selectively creating coding marks, such as coding dots, at the coding positions. In accordance with a second aspect of the present disclosure, a corresponding code pattern is provided.

Video from a video camera can be integrated into a still image, with which it shares common elements, to provide greater context and understandability. Pre-processing can derive transformation parameters for transforming and aligning the video to be integrated into the still image in a visually fluid manner. The transformation parameters can then be utilized to transform and align the video in real-time and display it within the still image. Pre-processing can comprise stabilization of video, if the video camera is moveable, and can comprise identification of areas of motion and of static elements. Transformation parameters can be derived by fitting the static elements of the video to portions of one or more existing images. Display of the video in real-time in the still image can include display of the entire transformed and aligned video image, or of only selected sections, to provide for a smoother visual integration.
