Image sensing device comprising dummy pixel row and active pixel rows coupled to read-out column line, and using a high speed active pixel row read-out method that reduces settling time by precharging the column line during a dummy pixel row selection time between active pixel row selection times

摘要

An image sensing device includes a pixel suitable for outputting a pixel signal through a read-out line during a read-out section and a precharge block suitable for precharging the read-out line to a voltage level corresponding to an initial voltage level of the pixel signal during a row non-selection section adjacent to the read-out section.
