Claim Text:
1. A device for correcting an injector characteristic, comprising: a micro control unit configured to generate a control pulse that controls an operation of an injector; and a driving semiconductor configured to detect and calculate a driving characteristic related to the injector, and compensate for injection timing of the control pulse based on a deviation in injection timing of the injector, wherein the driving semiconductor includes: an injector characteristic detector configured to detect the driving characteristic of the injector; a data processor configured to convert output from the injector characteristic detector into a data value; a micro core unit configured to generate deviation correction data for the injection timing of the injector based on the data from the data processor; a controller configured to generate a correction clock by applying the deviation correction data to the control pulse; and an output driving unit configured to control the injector in accordance with the correction clock.
