Image Processing Apparatus Compression for External Storage
Find Innovative SolutionsGenerate Solutions
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.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data is stored in external devices, then the image processing apparatus can retain and reuse image data, but the data volume becomes large consuming external storage capacity
Solution Approach 1:
The patent applies JPEG compression to transform image data into a more compact form, changing the data representation parameters to reduce storage requirements while maintaining acceptable image quality for electronic blackboard functionality
Solution Approach 2:
The patent creates a simplified copy of the original image data through compression algorithms, storing the compressed version in external devices while preserving the essential visual information needed for display and interaction

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.
