IMAGE PROCESSING APPARATUS AND INFORMATION DISPLAY METHOD USED IN THE IMAGE PROCESSING APPARATUS

An image processing apparatus includes a processor and a storage device to store instructions which cause the processor to operate as a specially programmed processor. The processor executes a multi-application in which a plurality of applications is combined, each of the applications configured to input, process, and output image data; displays a screen including display areas to enter input- and output-setting items; displays a multi-application screen including a feedback display area; identifies, when a content of the input- and output-setting items is changed for one application of the applications, another application for which a content of the input- and output-setting items is changed by the setting change for the one application; identifies a difference before and after the change in the content of the input- and output-setting items of the another application; and switches a display of the feedback display area in accordance with the difference to setting-change-influence information.
