1. An image processing apparatus having a plurality of functions including a predetermined function, the image processing apparatus comprising:
a display unit including a touch panel configured to receive a user operation;
a receiving unit configured to receive a display instruction for displaying a screen related to the predetermined function; and
a display control unit configured to display the screen related to the predetermined function,
wherein, in a case where the receiving unit receives the display instruction for displaying a first setting screen on which a setting value related to the predetermined function is displayed, the display control unit displays a transparent window having a same size as the first setting screen and capable of receiving a touch operation in a superimposed manner on the first setting screen at a surface over the first setting screen on the display unit, based on authentication processing for enabling a user operation for the setting value related to the predetermined function being required, and in a case where a user operation on the transparent window superimposed at the surface over the first setting screen is received, the display control unit displays an authentication screen capable of receiving the authentication processing on the display unit, and, when the authentication processing that is based on authentication information inputted on the authentication processing is successful and an authority of user information that is based on the authentication information with which the authentication processing is successful is an authority that allows the predetermined function to be used, the first setting screen is displayed at the surface of the display unit without superimposing the transparent window thereon,
based on the authentication processing being not required in the case where the receiving unit receives the display instruction for displaying the first setting screen on which the setting value related to the predetermined function is displayed, the display control unit does not display the transparent window,
when the authority of the user information that is based on the authentication information with which the authentication processing is successful is not an authority that allows the predetermined function to be used, the display control unit keeps the transparent window displayed in a superimposed manner on the first setting screen at the surface over the first setting screen on the display unit,
a user operation for the setting value related to the predetermined function is disable on the first setting screen in a case where the transparent window is superimposed on the first setting screen and where the first setting screen is not displayed at the surface on the display unit, and
a user operation for the setting value related to the predetermined function is enabled on the first setting screen in a case where the transparent window is not superimposed on the first setting screen and where the first setting screen is displayed at the surface on the display unit.
