Band Image Processing Control Under Limited Print Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems face challenges in storing and processing large image data due to limited memory capacity, leading to incomplete storage and processing of image data in memory areas, especially when printing on large-sized recording media.
Innovation Solution
The system controls the size of image data before processing by dividing it into manageable bands, specifying the target image data size based on the memory capacity and content of image processing, and applies image processing to these divided data segments, ensuring they fit within the memory constraints of the storage area.

Engineering Contradiction Analysis
1Reliability
If image data is obtained without size control before processing, then the complete image data can be processed, but the processed image data cannot be stored in the second memory area when it exceeds memory capacity
Solution Approach 1:
The system performs preliminary size control on the image data before processing by calculating the expected size after processing and comparing it with the second memory area capacity. If the expected size exceeds capacity, the system truncates the image data to an appropriate size before processing, ensuring the processed data can be stored without exceeding memory limits.
Solution Approach 2:
The system segments the image data into appropriate sizes based on the second memory area capacity and processing requirements. By dividing the image data into manageable segments that fit within memory constraints, the system enables complete processing while ensuring storage feasibility.
2Quantity of substance
If image data size is controlled before processing to fit memory capacity, then the processed data can be stored, but the control complexity increases
Solution Approach 1:
The system performs self-service by automatically calculating the required image data size based on the second memory area capacity and processing content, then autonomously controlling the data size without requiring external intervention or complex manual configuration.
Solution Approach 2:
The system uses feedback by calculating the expected size of processed image data and comparing it with the second memory area capacity. Based on this comparison, the system adjusts the input image data size to ensure the processed output fits within available memory, creating a closed-loop control mechanism.
