The display panel includes a first area and a second area. When a user operation on the first area is received on the operation receiving section, the controller displays an image based on the user operation in the first area. The controller performs second processing and third processing. The second processing corresponds to processing of storing a first image displayed in the first area and a second image which is a reduced image of the first image in the storage, and displaying the second image in the second area. The third processing corresponds to processing of displaying, when a user operation of selecting the second image is received on the operation receiving section, the first image corresponding to the selected second image in the first area. ## Claims ### Claim 1 An information processing device comprising: a display panel comprising a display area including a first area and a second area;
