FIELD: physics.
SUBSTANCE: components of a composite image are formed in charge form on targets of first and second television sensors with different exposure times, set based on an optimality criterion for each transmitted scene fragment. Amplification coefficients of video paths of each sensor are also determined from this criterion. Owing to this, in the output image of the television camera bright and light details are transmitted without limitation in white, since dark and/or low illumination details are transmitted with high signal-to-noise ratio ψ, and the dynamic gray gradation range expands.
EFFECT: wider dynamic gray gradation range for control objects.
