[en] A new generation of large area semiconductor based γ-ray camera for astrophysics space application has been developed through the γ-ray IBIS (Imager on Board INTEGRAL Satellite) telescope program, on board the ESA INTEGRAL satellite. This instrument features a coded-mask aperture imaging system, active and passive shields and two detector arrays. The first one (ISGRI : INTEGRAL Soft Gamma-Ray Imager) is made of 16384 CdTe detectors (4x4 mm large, 2 mm thick) operating at room temperature and will operate between 15 keV and 1 MeV. The second detector array (PICsIT : Pixelated CsI Telescope) is made of 4096 CsI scintillators (9.2x9.2 mm large, 30 mm high) coupled to silicon PIN photodiodes working between 150 keV and 10 MeV. IBIS combine broad band energy, spectroscopic capabilities and high spatial resolution imaging (12 arcmin) over a wide field of view (∼20 deg. x 20 deg., 50% sensitivity). A 'flight-like' model of the detectors has been built, integrated and successfully tested. After a description of the IBIS imaging principle, we will report results obtained with the qualification model of the ISGRI camera
