An integrated active pixel photosensor includes a matrix array of pixels. Each pixel includes a photosensitive component, an amplifier component and a reset to initial state component. The matrix array further includes, for controlling the pixels, an addressing device, a power supply device, a reset to initial state device and a device for reading luminance information picked up by the pixels to extract the information from the matrix array. The addressing, power supply, reset and reading devices are implemented by the same plurality of matrix array column and row lines. The photosensor further includes logic control devices external to the matrix array and connected to the column and row lines to enable selective control in each pixel of the power supply, addressing, return to initial state and read functions.
