Abstract: A light sensing device (100) including at least one light sensor (102) is provided. The at least one light sensor (102) is configured to be exposed to a light image. In response to the light image, the at least light sensor (102) is configured to generate a first signal via line (120). The light sensing device (100) further includes a measuring device (104) coupled to the at least one light sensor (102). The light sensing device (100) also includes a sampling generator (114) configured to generate a sampling signal (CK) to the measuring device (104). The sampling signal (CK) is inhibited when the first signal via line (120) is lesser than or equal to a predetermined value (Vt). Upon inhibition of the sampling signal (CK), the measuring device (100) retains a measure of the first signal generated via line (120).
