A display control apparatus in a display system including an acquisition unit configured to acquire a first notification information to be notified to a driver of a vehicle, a detection unit configured to detect a predetermined state of either the vehicle or the driver, and a display unit configured to generate a predetermined image based on the first notification information acquired via the acquisition unit, the display control apparatus comprising: a control unit configured to control the display unit such that in a case where the detection unit detects a first predetermined state at a first time, a first predetermined image for representing the first notification information is generated and displayed on a display medium such that the first predetermined image is displayed in an area on said display medium outside a first restricted area defined in advance in relation to the first predetermined state; and a determination unit configured to make a judgment such that in a case where the detection unit detects a second predetermined state different from the first predetermined state at a second time later than the first time, the determination unit judges whether there is a predetermined change between the first predetermined state and the second predetermined state, wherein in a case where the determination unit judges that there is a predetermined change, the control unit controls the display unit such that a second predetermined image for representing the first notification information is generated and is displayed on the display medium such that the second predetermined image is displayed in an area outside a second restricted area on the display medium defined in advance in relation to the second predetermined state, and the second restricted area is different from the first restricted area in terms of either location, of size, of number, and for of shape. a control unit configured to control the display unit such that in a case where the detection unit detects a first predetermined state at a first time, a first predetermined image for representing the first notification information is generated and displayed on a display medium such that the first predetermined image is displayed in an area on said display medium outside a first restricted area defined in advance in relation to the first predetermined state; and a determination unit configured to make a judgment such that in a case where the detection unit detects a second predetermined state different from the first predetermined state at a second time later than the first time, the determination unit judges whether there is a predetermined change between the first predetermined state and the second predetermined state, wherein in a case where the determination unit judges that there is a predetermined change, the control unit controls the display unit such that a second predetermined image for representing the first notification information is generated and is displayed on the display medium such that the second predetermined image is displayed in an area outside a second restricted area on the display medium defined in advance in relation to the second predetermined state, and the second restricted area is different from the first restricted area in terms of either location, of size, of number, and for of shape.
