Abstract: An image plane consists of a number of pixels, two of which are shown. Each pixel comprises a photodiode and two transistors (M1, M2). Each pixel is connected by a signal bus (10) to a respective storage node located off the image plane. Each storage node comprises two capacitors (Csn_1, Csn_2) and associated switches (S2_1, S2_2). The transistor M2 applies a reset pulse to the pixel, and the transistor M1 connects the pixel to a given conductor of the signal bus (10) and thence to the storage node. The pixel transistors can be operated simultaneously, and the sensed values subsequently transferred from the storage nodes sequentially.
