Abstract: Digital image processing circuitry converts images in a color filter array (CFA) color space to images in a luminance-chrominance (YUV) 4:2:0 color space, and the images in the YUV 4:2:0 color space are processed by the digital image processing circuitry in the YUV 4:2:0 color space, for example, to apply noise filtering, etc. The converting includes simultaneously receiving pixel data defining a macro-pixel in the CFA color space. The processing in the YUV color space is applied on a macro-pixel level to the macro-pixel of the image in the YUV color space.

Abstract: In an embodiment, a method includes: receiving data signals from a plurality of pixels of an array of pixels; generating a plurality of signal-to-noise ratios by determining signal-to-noise ratios for each respective pixel of the plurality of pixels on the basis of the data signals received from the respective pixel; and filtering the data signals received from each pixel of the plurality of pixels by using an adaptive filter configured on the basis of the plurality of the signal-to-noise ratios to generate filtered data signals.

Abstract: A device for assembling at least two shots of a scene acquired by at least one sensor includes a memory and processing circuitry. The processing circuitry is configured to save, in the memory, a first data set contained in a first signal generated by each pixel of the sensor and indicative of a first shot of the scene, and a second data set contained in a second signal generated by each pixel of the sensor and indicative of a second shot of the scene. The processing circuitry is further configured to assemble the first and second shots on the basis of the content of the first and second data sets of a plurality of pixels in order to form a resulting scene.

Abstract: An electronic circuit includes a clock signal generator configured to deliver a clock signal. A propagation circuit is configured to propagate the clock signal on a plurality of propagation branches. A number of timers are coupled to at least some of the branches. The timers are clocked by corresponding replicas of the clock signal and configured to generate a pulse signal every N pulses of the corresponding replica of the clock signal. A comparator is configured to generate an alarm signal having a first state when two of the pulse signals are phase-offset with respect to one another.
