Bolometer type uncooled infrared ray sensor and method for driving the same |
摘要 |
A bolometer type uncooled infrared ray sensor includes: an image pickup region having detection pixels arranged in a matrix form on a semiconductor substrate to detect incident infrared rays; a plurality of row selection lines provided in the image pickup region; current sources capable of letting constant currents flow through the respective row selection lines; a plurality of signal lines provided in the image pickup region; voltage readout circuits provided so as to respectively correspond to the signal lines to read out signal voltages generated on the respectively corresponding signal lines; coupling capacitances respectively provided between the respective signal lines and the corresponding voltage readout circuits; and a calculator which calculates a difference between two signal voltages read out by the voltage readout circuits, corresponding to outputs of the same detection pixel for two different current values supplied from the current sources. |
