Abstract: An example image capture device determines a region of interest using a first image captured while a light source is powered off and a second image captured while a light source is powered on and uses the region of interest to automatically set configurations. In one example, an image capture device includes a controlled light source, an image sensor configured to capture images, and a processing unit configured to cause the image sensor to capture a first image of a scene while the controlled light source is powered off, cause the image sensor to capture a second image of the scene while the controlled light source is powered on, calculate luminance differences between a plurality of regions in the first image and a plurality of collocated regions in the second image, and determine that a region of interest includes those regions for which the luminance differences exceed a threshold.

Abstract: A digital imaging device is provided that includes a high modulation transfer function lens and a multicolor pixel array sensor. The lens is operable to receive an incoming signal and to provide a focused signal based on the incoming signal. The multicolor pixel array sensor, which is adjacent to the lens, is operable to receive the focused signal from the lens and to generate a sensor signal based on the focused signal. The device may also include an interpolator coupled to the multicolor pixel array sensor. The interpolator is operable to receive the sensor signal from the multicolor pixel array sensor and to interpolate the sensor signal to generate an interpolated signal.

Abstract: A bi-directional isolation scheme is described in which digital data, including clock information, may be communicated bi-directionally across a single isolation barrier without requiring a phase locked loop (PLL) based clock recovery procedure. In this way, the lead-time needed by the receiving circuit to recover the data clock signal may be reduced and the polarity (or 180° phase) ambiguities often associated with PLL-based methods may be avoided.
