Duplex Sheet Image Processing for Real-Time Pattern Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems inefficiently manage memory usage when checking for specific patterns on both surfaces of a recorded sheet, leading to increased storage requirements and processing time.
Innovation Solution
An image processing apparatus that reads both surfaces of a sheet simultaneously, combines the data, and checks for specific patterns in real-time, reducing the need for intermediate storage and minimizing waiting times for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pieces of first data and pieces of second data are stored in memory for sequential pattern checking, then pattern detection can be performed on both surfaces, but memory usage increases and processing time is extended due to waiting for data to be ready for checking
Solution Approach 1:
The patent combines pieces of first data and pieces of second data before pattern checking is performed. By preparing the combined data structure in advance and performing checks on the combined data directly, the system eliminates the need to store large amounts of raw first and second data separately in memory, thus reducing memory usage while maintaining pattern detection capability
Solution Approach 2:
The patent extracts only the necessary combined information from the first and second data for pattern checking, rather than storing and processing all raw data. This selective extraction approach reduces the quantity of data held in memory to only what is needed for the detection task
2Measurement precision
If pieces of first data and pieces of second data are stored in memory for sequential pattern checking, then complete data is available for analysis, but processing time increases due to sequential checking and waiting periods
Solution Approach 1:
The patent performs pattern checking on combined data as soon as it is available, rather than waiting for all first and second data to be fully stored and processed sequentially. This preliminary checking approach overlaps data preparation and analysis phases, reducing total processing time while maintaining detection accuracy
Solution Approach 2:
The patent enables continuous pattern checking on combined data without interruption or waiting periods. By maintaining a continuous flow of data combination and checking operations, the system eliminates idle waiting time that would occur in sequential processing, thereby reducing overall processing time

AI summary
An image processing apparatus includes a processor configured to: read a first surface of a recorded sheet to generate pieces of first data; read a second surface of the recorded sheet to generate pieces of second data; combine the generated pieces of first data with the respective generated pieces of second data; and check whether a specific pattern is present, the specific pattern being a pattern which is possibly included in the pieces of combined data.
