A method for acquiring images using at least one CMOS-type sensor with four transistors including an acquisition node and a read node, where the read node can receive a compression signal, including a step of reading a reference state of the sensor; a reset step; an integration step, during which the sensor is exposed and during part of which the compression signal is applied to the read node; and a step of reading the data acquired during the integration step; the read node being, during the integration step, isolated from the acquisition node, except immediately before the application of the compression signal, at which time the acquisition node is connected to the read node long enough to enable a transfer of the charges present at the acquisition node to the read node.
