Abstract
When a reading target object that includes a light emitting region is set as a reading target, the light emitting region is detected by a reading mechanism of a reading unit. The reading unit is caused to read the detected light emitting region, and in the reading, a read operation by the reading unit is controlled based on change of an amount of light received from the light emitting region.
Claims21
A reading apparatus comprising:
- at least one processor;
- a reading control unit configured to cause a reading sensor to read a reading target object;
- and
- a display control unit configured to display an error message on a screen,
- wherein the display control unit displays the error message based on a detection of a decrease in an amount of light emitted from the reading target object during reading of the reading target object by the reading sensor in a period from when reading of the reading target object is instructed to when reading of the reading target object is finished, and
- wherein the reading control unit and the display control unit are implemented by the at least one processor.
A control method executed in a reading apparatus, the method comprising:
- causing a reading sensor to read a reading target object;
- and
- displaying an error message on a screen, based on a detection of a decrease in an amount of light emitted from the reading target object during reading of the reading target object by the reading sensor in a period from when reading of the reading target object is instructed to when reading of the reading target object is finished.
A non-transitory computer-readable storage medium storing a program for causing a computer to operate so as to display an error message on a screen, based on a detection of a decrease in an amount of light emitted from a reading target object during reading of the reading target object by a reading sensor in a period from when reading of the reading target object is instructed to when reading of the reading target object is finished.
