Abstract
An image sensor comprises rows and columns of pixels. Each pixel comprises an image sensing element and a switching device. The switching device enables a signal of the image sensing element to be provided to the associated column conductor. The switching device has two inputs—a first input defined by the row conductor, and a second input. Two adjacent columns of pixels are associated with each column conductor, and the two columns of pixels between adjacent column conductors are associated with a respective shared control line providing the second input. The switch arrangement with two inputs enables individual pixels to be isolated. The sharing of control lines between pairs of columns of pixels means that each pixel requires the same number of connections as in a conventional array with only a single switch control input.
