Image sensing device for cancelling a horizontal banding noise

An image sensing device, comprising:

• a pixel array including a plurality of unit pixels coupled to a plurality of row lines, wherein each unit pixel includes a photo-diode for generating photo charges corresponding to an incident light and a transfer transistor for transferring the photo charges to a floating diffusion (FD) node in response to a transfer control signal transferred through a corresponding row line;
• a first row control circuit disposed at a first side of the pixel array and suitable for providing, to odd row lines among the row lines, the transfer control signal having a voltage level between a first voltage and a second voltage;
• a second row control circuit disposed at a second side of the pixel array and suitable for providing, to even row lines among the row lines, the transfer control signal;
• a first bias compensation circuit disposed at the second side and suitable for driving the transfer control signal to the second voltage during a reset read-out section of the odd row lines;
• and
• a second bias compensation circuit disposed at the first side and suitable for driving the transfer control signal to the second voltage during a reset read-out section of the even row lines.
