Display apparatus, display method, and image processing system

摘要

An error process unit for displaying an error message has a first process unit for detecting errors of various devices based on detected signals from sensors associated therewith, and a second process unit for outputting error messages depending on combinations of the detected errors. The second process unit has a retriever for retrieving a present error pattern based on a combination of the detected errors from an information table, and a message output process unit for reading an error message corresponding to the present error pattern and outputting the error message to a display if the present error pattern is present in the information table.
