Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large data sizes of high-resolution texture images cause slow operations in image editing and printing processes, leading to inefficiencies in image editing and printing systems.
Innovation Solution
An image forming apparatus with an image memory, receiving unit, determination unit, search unit, and converter that replaces low-resolution texture data with high-resolution data stored in the memory, enabling efficient image processing and printing by converting received image data for output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution texture data is used for printing, then image quality is improved, but data size increases causing slow processing operations
Solution Approach 1:
The patent segments texture data into two resolution levels: low-resolution data for image editing operations and high-resolution data for final printing. This segmentation allows each stage to use appropriately sized data, improving both editing performance and print quality without compromise.
Solution Approach 2:
The patent performs preliminary processing by storing both low-resolution and high-resolution versions of texture data in advance. During editing, the system prepares the low-resolution data for quick manipulation, while the high-resolution data is retained for the final printing stage, eliminating the need to process large data during editing operations.
2Productivity
If low-resolution texture data is used for editing, then processing speed is improved, but printed image quality deteriorates
Solution Approach 1:
The patent divides texture data into multiple resolution versions stored separately. The editing system accesses only the low-resolution segment for fast processing, while the high-resolution segment remains available for the printing stage, ensuring both fast editing and high-quality output.
Solution Approach 2:
The patent introduces an intermediary mechanism (the image forming apparatus with multiple image memories) that mediates between the editing system and final output. This intermediary stores and manages multiple resolution versions, allowing the editing system to work with small data while the printing system accesses high-resolution data through the intermediary.
3Manufacturing precision
If high-resolution texture data is transmitted for printing, then output quality is improved, but transmission data size and time increase
Solution Approach 1:
The patent extracts only the necessary high-resolution texture data from the complete set and transmits it to the image forming apparatus. By taking out only what is needed for printing rather than transmitting all high-resolution data, the system reduces transmission time while maintaining output quality.
Solution Approach 2:
The patent performs preliminary preparation by having the image forming apparatus store high-resolution replacement image data in advance. When printing is needed, the system only needs to transmit identification information or small data segments rather than the entire high-resolution texture set, significantly reducing transmission time.

AI summary
An image forming apparatus includes an image memory, an image receiving unit, an image determination unit, an image search unit, an image forming unit, and an image converter. The image memory stores replacement image data. The image receiving unit receives image data from the outside. The image determination unit determines whether the received-image data includes to-be-replaced image data. The image search unit searches, in a case where it is determined that the received-image data includes the to-be-replaced image data, the image memory for replacement image data corresponding to the to-be-replaced image data. The image forming unit forms an image. The image converter converts, in a case where the corresponding replacement image data is detected, the received-image data into to-be-output image data in which the to-be-replaced image data is replaced with the corresponding replacement image data, and causes an image based on the to-be-output image data to be formed.
