Patent ID: 7690751

Claim:
A recording apparatus for recording an image using a recording head that affects ink with thermal energy from a plurality of electrothermal transducers to discharge the ink via nozzles, wherein the recording head includes a plurality of temperature sensors, each of which is respectively positioned in correspondence with each electrothermal transducer; and a temperature detection circuit configured to select each one of the plurality of temperature sensors and obtain temperature data detected by the selected temperature sensor; the recording apparatus comprising: a first temperature detection unit, in a state that a first electrothermal transducer is not driven with an electric current, configured to obtain first temperature data that the temperature sensor corresponding to the first electrothermal transducer detects by way of the temperature detection circuit; a second temperature detection unit, in a state that the first electrothermal transducer is driven with an electric current, configured to obtain second temperature data that the temperature sensor corresponding to the first electrothermal transducer detects by way of the temperature detection circuit; an acquisition unit that acquires correction data for correcting the temperature data that the temperature sensor corresponding to the first electrothermal transducer detects, based on the first and the second temperature data obtained by the first and second temperature detection units; and a correction unit configured to correct the temperature data the temperature sensor corresponding to the first electrothermal transducer detects, in accordance with the correction data acquired by the acquisition unit.
