AN IMAGE SENSOR AND A METHOD FOR READ-OUT OF PIXEL SIGNAL

An image sensor (100), comprises: an array of pixels (110) for detecting light incident on the pixel, wherein each pixel (110) in the array comprises a photodetector (112) and an in-pixel correlated double sampling, CDS, circuitry (114) to output a CDS signal representative of a difference between a photointegrated signal and a reset signal; a column line (130), which extends along and is associated with a column of pixels (110) in the array; a voltage drop correction line (134), which extends along and is associated with the column of pixels (110), wherein the voltage drop correction line (134) is configured to provide a correction voltage signal to a pixel (110) such that the correction voltage signal is added to the CDS signal for forming the pixel signal received by the column line (130) and corrects for voltage drop of the pixel signal in read-out through the column line (130).
