Printing Apparatus Group Element Combining for Color Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During image processing, especially when flattening is performed, intermediate data overflow can lead to stepwise combining of groups, resulting in unintended color output, as the existing techniques fail to correctly manage the combination of objects and background elements within the same memory threshold.
Innovation Solution
A printing apparatus with a reception unit, generation unit, determination unit, and combining unit that assesses the total size of intermediate data and selectively combines only the data of specific objects without combining with the background when the threshold is exceeded, ensuring the intended color output by managing the data processing and combining operations.

Engineering Contradiction Analysis
1Quantity of substance
If flattening is performed to reduce intermediate data size, then memory overflow is prevented, but combining processing becomes stepwise resulting in incorrect color output
Solution Approach 1:
The patent segments the combining processing into two distinct phases: (1) combining processing within groups performed before flattening to ensure correct color calculation, and (2) flattening processing performed after group combining to reduce memory usage. This segmentation resolves the contradiction by maintaining color accuracy through proper processing sequence while still achieving memory optimization.
Solution Approach 2:
The patent performs combining processing of group elements as a preliminary action before flattening is applied. By completing the color-critical combining operations first, the system ensures that color accuracy is maintained while subsequent flattening can then reduce intermediate data size without affecting the already-calculated color values.
2Manufacturing precision
If intermediate data is stored for all objects in a group, then correct color combining is achieved, but memory capacity is exceeded
Solution Approach 1:
The patent segments the processing timeline into distinct phases: group combining phase (where all group elements are processed together with full memory availability) and flattening phase (where memory is optimized). This allows the system to maintain color accuracy when needed while achieving memory efficiency afterward.
Solution Approach 2:
The patent maintains continuous combining processing for all group elements before interrupting for flattening. This ensures that the color calculation process remains uninterrupted and accurate, while the subsequent flattening operation can then reduce memory usage without breaking the color computation continuity.

AI summary
An object of the present invention is to provide an image processing apparatus capable of combining a group element so that a color intended by a user is output ultimately even in the case where flattening is performed on the way of the processing performed on the group.
