  Imaging in a broad light-intensity regime with a high signal-to-noise ratio
is a key capability in fields as diverse as Quantum Metrology and Astronomy.
Achieving high signal-to-noise ratios in quantum imaging leads to surpassing
the classical limit in parameter estimation. In astronomical detection, the
search for habitable exoplanets demands imaging in the infrared its atmospheres
looking for biosignatures. These optical applications are hampered by detection
noise, which critically limits their potential, and thus demands photon-number
and spatial resolution detectors. Here we report an imaging device in the
infrared wavelength range able to arbitrarily reduce the readout noise. We
built a Measured Exposure Skipper-CCD Sensor Instrument equipped with a thick
back-illuminated sensor, with photon-number-resolving capability in a wide
dynamic range, spatial resolution, high quantum efficiency in the near-infrared
and ultra-low dark counts. This device allows us to image objects in a broad
range of intensities within the same frame and, by reducing the readout noise
to less than 0.2e$^-$, to distinguish even those shapes with less than two
photons per pixel, unveiling what was previously hidden in the noise. These
results pave the way for building high-standard infrared imagers based on
Skipper-CCDs.
