    Abstract: Digital video signals, such as the signals generated by an image sensor (1) in a Bayer format, in which the pixels of each line are alternatively coded with two colours, and then converted into an encoded format. In the encoded format, the pixels of the digital video signals are reordered into sets of adjacent pixels, such that the sets group pixels coding the same colour. The encoded signal data is suitable for transmission over a bus (B) in conditions of reduced switching activity.

    Abstract: A method for obtaining a high-resolution digital image from a plurality of starting images P,S formed by pixel matrices and acquired at a lower resolution. The method comprises a phase of combining the plurality of starting images P,S to generate a provisional high-resolution image HR (0) formed by a pixel matrix.
    The method also comprises a calculation phase to associate a respective error with at least a part of the pixels of the provisional image HR (0) , said calculation phase providing a first error associated with at least one first pixel, and a phase of at least partially processing the provisional image by modifying the pixels of this image on the basis of the respective errors associated with them.
    The method is characterized by the fact that the calculation phase includes the phase of:

    calculating a second error to associate with at least one second pixel situated in the vicinity of said first pixel in the matrix ( HR (0) ), said second error being calculated by using the first error associated with said at least one first pixel.

    Abstract: A method for improving the quality of a digital image acquired with a non-optimal exposure. The method, which is applied directly to the image in CFA (Colour Filter Array) format, identifies the regions of the image that are most important from the perceptive or contentual point of view by means of simple statistical measures. The image is then transformed by inverting the response function in such a manner as to optimize the quality of these regions.
