A novel image processing apparatus that provides effective digitized audio while ensuring audio clarity and outputs image data adding the digitized audio is provided. The image processing apparatus includes an audio recording unit that stores audio data based on input audio in an audio storage device, a data editing unit that adds the audio data to image data, control circuitry that instructs the recording unit to record when a predetermined recording condition is satisfied, and a data output unit to output the image data in an appropriate format. For example, the control circuitry considers a condition that the scanner scans the document set on a platen as the recording condition.
