Abstract
An information processing apparatus includes a control unit and an operation unit. The control unit is configured to generate image data for image display. The operation unit includes a display unit, and is configured to display a screen on the display unit based on the image data generated by the control unit and to accept user operation. The control unit executes first processing for identifying, based on a state of signal output from the operation unit, whether a malfunction has occurred in one of the control unit and the operation unit. The operation unit executes, independently of the first processing by the control unit, second processing for identifying, based on a state of signal output from the control unit, whether the malfunction has occurred in the control unit or in the operation unit.
