Patent

CA 2008689

In an image sensing device which performs a white compressing process before performing an automatic gain adjusting action on an image signal, a white compression circuit is arranged to have a white compressing characteristic which is variable in association with the automatic gain adjustment; and the gain of an A/D converter which is provided for A/D converting the output of the white compression circuit is arranged to be adjustable.

Dans un dispositif de lecture d'image qui effectue la compression des blancs avant de régler automatiquement le gain au niveau d'un signal, un circuit de compression des blancs est monté de façon à présenter une caractéristique de compression des blancs qui varie conjointement avec le réglage automatique de gain; et le gain d'un convertisseur A/N destiné à la conversion A/N des sorties du circuit de compression des blancs est réglable.
