A pressure generator is driven to eject ink droplets from a nozzle orifice such that a plurality of flushing operations are intermittently repeated with a first time interval, when a recording operation of a recording head is not performed. The apparatus for verifying the integrity of firmware of an embedded system includes a target integrity code obtainment unit for obtaining a target integrity code of firmware of the embedded system. In this manner, some embodiments provide a vibrancy process that non-uniformly adjusts saturation levels of an image in order to preserve saturation levels for skin tones appearing within the image. The NEW SECONDARY CODE EXECUTION START POINT signal is generated after the instructions from the original secondary code sequence are removed from the pipeline flattener and the first new secondary code instruction is removed from the pipeline flattener.
