Abstract : Recently, the EUSO-BALLOON instrument, the pathfinder for future space telescopes of the JEM-EUSO family, has been flown during one night in the stratosphere by CNES. The recording of light intensity emitted from earth or its atmosphere by its fast and high-resolution pixel UV camera was one of the main goals of this mission. We present an analysis on the in-flight UV camera calibration data. These data allow the extraction of the signal and background components in the recorded photoelectron count spectrum for each pixel, under the assumption of a parameterised multi-component statistical model describing the experimental setup. We assess the detection performances such as the detection sensitivity, the signal to noise ratio. We discuss as well the implication of this calibration in the estimation of the statistical and systematic errors on the photoelectron rates measurement.
