Solution Overview

Problem

The existing image processing apparatuses generate large data volumes for stored image data, leading to storage capacity issues in external devices.

Innovation Solution

The image processing apparatus reduces data volume by modifying and compressing image data, particularly background images, when storing them in external devices, using techniques such as JPEG compression and adjusting compression ratios.

AI summary

An image processing apparatus, which performs image processing on a superimposed image in which a plurality of images are superimposed, generates the superimposed image by superimposing at least a stroke image and a background image; determines whether a storage destination, which is for storing image data indicating the superimposed image, is an external device coupled to the image processing apparatus; and modifies the image data, in response to the storage destination being determined to be the external device at the determining, such that the aforementioned problems are solved.
