Abstract: An image sensor includes a plurality of pixels, where each of the plurality of pixels includes a photodiode. The image sensor is configured to capture images of a scene exposed with a flickering light source by for each of the plurality of pixels, acquiring a value representative of a light level at a corresponding pixel by gradually varying a value of sensitivity of the corresponding pixel.

Abstract: Requests are received by a routing circuit. A plurality of first round-robin arbitration circuits are coupled to the routing circuit. There are as many first round-robin arbitration circuits as there are possible priority levels for the requests. The routing circuit operates to transmit each received request to a number of first round-robin arbitration circuits determined according to the priority level of the request. A second round-robin arbitration circuit has inputs respectively connected to the outputs of the first round-robin arbitration circuits.

Abstract: A low-dropout voltage regulation device includes a power stage having an output terminal coupled to a load circuit, the load circuit being operable in a plurality of operating modes. The load circuit is configured to receive a different respective output current when in each of the plurality of operating modes. An error amplifier has an output coupled to an input terminal of the power stage. A compensation circuit is coupled to the input terminal of the power stage and is operable in a plurality of selectable configurations that are respectively tailored to the plurality of operating modes. The plurality of selectable configurations are selectable in response to a control signal representative of a current operating mode of the load circuit.

Abstract: The present disclosure relates to a tone mapping method for a succession of images implemented by an image processing device. The method including a) the division of the images of the succession of images in a plurality of sub-blocks of first pixels; b) for a first image (INPUT_IMAGEf) of the succession of images, the creation of a first mini-image (MPICf) comprising pixels of the first mini-image, each pixel of the first mini-image representing a corresponding sub-block of the first image, the intensity of each pixel of the first mini-image being representative of the intensity of the first pixels of the corresponding sub-block; c) the storage of the first mini-image (MPICf) in a memory; and d) for a second image (INPUT_IMAGEf+1) of the succession of images, the modification of the second image according to the first mini-image (MPICf) in order to generate an output image.

Abstract: A memory includes writable memory units. Each memory unit is configurable: in a retention state wherein the memory unit is capable of retaining data until a subsequent power-off of the memory unit, and in a non-retention state wherein the memory unit does not retain data and consumes less power than in the first state. A controller configures any memory unit of the memory having undergone at least one write access since its last power-up to be in the retention state. The controller further configures at least one memory unit of the memory that has not undergone any write access since its last power-up in the non-retention state.

Abstract: Methods and devices for adjusting a read threshold voltage of bitlines are provided. One such method includes adjusting a read threshold voltage of bitlines coupled to memory points of a memory circuit. The read threshold voltage is initially set to a first value. First data are written in the memory points and second data are read from the memory points. The second data are compared to the first data, and the threshold voltage is decreased by a second value in response to a comparison error of one of the second data with the corresponding first data.

Abstract: A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.
