Abstract:
1. An image reading apparatus comprising: an operation unit; a setting unit configured to set one of a plurality of operation modes, in which different processing is executed for a document, in accordance with an operation content of the operation unit; a reading unit configured to read the document in response to a reading execution request from the operation unit; a change unit configured to change a reading condition by the reading unit in accordance with operation content of the operation unit; a storage unit configured to store a frequency that the reading condition is changed after setting the operation mode, for each of the operation modes; and a control unit configured to control the reading unit whether or not to execute a reading preparation operation before the reading execution request is made depending on the set operation modes set by the setting unit, wherein, when the set operation mode is a first operation mode, the control unit is configured to control the reading unit to execute the reading preparation operation for the first operation mode before the reading execution request is made and, wherein, when the set operation mode is a second operation mode, the control unit is configured to control the reading unit to execute the reading preparation operation for the second operation mode after the reading execution request is made without executing the reading preparation operation for the second operation mode before the reading execution request is made, wherein the control unit is configured to: control an operation mode having a low frequency as the first operation mode; and control an operation mode having a high frequency as the second operation mode.
