Abstract
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.
Claims16
An image sensing device, comprising:
- 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.
An image sensing device, comprising:
- an active pixel coupled to a column line, and suitable for outputting a pixel signal through a column line during a read-out section;
- and
- a dummy pixel coupled to the column line, and suitable for precharging the column 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.
A read-out method of an image sending device, comprising:
- precharging a column line to a voltage level corresponding to a reset level of a pixel signal during a row non-selection section;
- charging a floating diffusion node with a predetermined voltage in advance during the row non-selection section;
- and
- reading out the pixel signal corresponding to a voltage level charged in the floating diffusion node through the column line during a row selection section subsequent to the row non-selection section.
