An image processing apparatus includes a camera, a document sheet image determining portion, an operation determining portion, and an image processing portion. The document sheet image determining portion determines whether or not document sheet image data is contained in photographic image data that has been obtained by photographing with the camera installed on the image processing apparatus. The operation determining portion determines whether or not operation image data is contained in the photographic image data, the operation image data showing a pattern of user's hand and corresponding to an operation for processing the document sheet image data. The image processing portion executes the processing of the document sheet image data based on the operation corresponding to the operation image data when it is determined that the document sheet image data and the operation image data are contained in the photographic image data.
