ABSTRACT:
Provided is an image recording apparatus having a plurality of functions, including a plurality of light emitting diodes (LEDs) for displaying an operational state of each of the plurality of functions; an LED controller for outputting to the plurality of LEDs a duty cycle for adjusting a brightness of the LEDs corresponding to the operational state of each of the plurality of functions; and a CPU for outputting to the LED controller a register value which changes the duty cycle corresponding to the operational state of each of the plurality of functions. Therefore, the image recording apparatus displays an operation state using its own LED so that the visual effect can be obtained to display the state of an operation of a presently performed function.
