Claim:
1. An image capture instrument, comprising: an image formation optics, suitable for forming an image of a scene in a focal plane from a radiation originating from said scene, the image formation optics having a pupil of diameter D and a focal length f determining a numerical aperture N and a spatial cut-off frequency f where λ is a wavelength of the radiation; a row of photodetectors situated in the focal plane, with a pitch p of the photodetectors which is constant along the row; and a controller suitable for controlling readings of accumulation signals produced respectively by the photodetectors, the controller defining a series of segments within the row, which each comprise one same number of adjacent photodetectors, called a segment length, and for controlling the readings of the accumulation signals by adding together said accumulation signals for photodetectors which belong to one and the same segment, the controller further defining the segments so that an offset length M between two successive segments in the row, expressed as a number of photodetectors, is constant along the row, and greater than 1/(2·f C ·p), wherein the instrument being characterized in that the segment length is greater than the offset length M, and less than twice said offset length M.
