Infrared imaging element comprising temperature detection pixels, drive lines, signal lines, vertical scanning circuit, signal line selection circuit, and one or more read circuits, and air conditioner equipped with the same

An infrared imaging element comprising:

• a pixel array unit that includes a plurality of temperature detection pixels each of which includes a diode and generates an electric signal in accordance with infrared rays received from an outside, the temperature detection pixels being arrayed in a two-dimensional fashion in rows and columns;
• a plurality of drive lines that are provided in rows, each of the drive lines commonly connecting first ends of the temperature detection pixels in one of the rows of the temperature detection pixels;
• a plurality of signal lines that are provided in columns, each of the signal lines commonly connecting second ends of the temperature detection pixels in one of the columns of the temperature detection pixels;
• a vertical scanning circuit that sequentially selects the drive lines;
• a signal line selection circuit that sequentially selects the signal lines;
• and
• one or more read circuits that amplify an electric signal from one of the temperature detection pixels connected to both one of the drive lines selected by the vertical scanning circuit and one of the signal lines that is selected by the signal line selection circuit, a total number of the read circuits being smaller than a total number of the signal lines connected to the columns of the temperature detection pixels.
