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 image sensor including: a plurality of pixels each including a photodiode coupled to first and second capacitive elements by first and second transistors; a control circuit provided to acquire, for each pixel, a first and second value V_S and V_M representative of illumination levels of the photodiode during the first second periods, the first period being divided into a plurality of first sub-periods and the second period being divided into a plurality of second sub-periods, the first and second sub-periods sub-periods being interlaced; and a sum circuit capable of calculating, for each pixel, a value V_MS=C_S*V_S+C_M*V_M, C_S et C_M being first and second coefficients such that values C_S*V_S and C_M*V_M are substantially equal when the illumination of the photodiode is continuous.
