An electronic apparatus comprising: a processor; and a memory having program code stored thereon, the program code being such that, when it is executed by the processor, it causes the processor to: control a display of a first parameter-setting image that relates to values of two parameters related to imaging, the first parameter-setting image comprising a graph and an indicator point that is movable by user input, where the values of the two parameters related to imaging are set based on a location of the indicator point in the graph; and display, in association with the first parameter-setting image, a second parameter-setting image that relates to values of a third parameter related to imaging; wherein the first parameter-setting image enables the user to set values of a first parameter related to imaging and a second parameter related to imaging based on the location of the indicator point in the graph; the second parameter-setting image enables the user to set values of the third parameter related to imaging; at least a portion of the second parameter-setting image is movable relative to the first parameter-setting image by user input and the value of the third parameter is set based on a location of the portion of the second parameter-setting image relative to the first parameter-setting image; and the second parameter-setting image is displayed in association with the first parameter-setting image by extending a reference line from the graph of the first parameter-setting image to contact the second parameter-setting image, the reference line passing through the indicator point. a processor; and a memory having program code stored thereon, the program code being such that, when it is executed by the processor, it causes the processor to: control a display of a first parameter-setting image that relates to values of two parameters related to imaging, the first parameter-setting image comprising a graph and an indicator point that is movable by user input, where the values of the two parameters related to imaging are set based on a location of the indicator point in the graph; and display, in association with the first parameter-setting image, a second parameter-setting image that relates to values of a third parameter related to imaging; control a display of a first parameter-setting image that relates to values of two parameters related to imaging, the first parameter-setting image comprising a graph and an indicator point that is movable by user input, where the values of the two parameters related to imaging are set based on a location of the indicator point in the graph; and display, in association with the first parameter-setting image, a second parameter-setting image that relates to values of a third parameter related to imaging; wherein the first parameter-setting image enables the user to set values of a first parameter related to imaging and a second parameter related to imaging based on the location of the indicator point in the graph; the second parameter-setting image enables the user to set values of the third parameter related to imaging; at least a portion of the second parameter-setting image is movable relative to the first parameter-setting image by user input and the value of the third parameter is set based on a location of the portion of the second parameter-setting image relative to the first parameter-setting image; and the second parameter-setting image is displayed in association with the first parameter-setting image by extending a reference line from the graph of the first parameter-setting image to contact the second parameter-setting image, the reference line passing through the indicator point.
