Solution Overview

Problem

Conventional scroll operations require a fixed drawing interval time table specific to existing device models, making it cumbersome to adapt to new device models without rewriting the table.

Innovation Solution

An information processing device and method that calculates moving interval values for object coordinates based on elapsed time and movement time, allowing dynamic adjustment of scroll operations without pre-defined tables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed drawing interval time table is used for scroll operations, then the scroll operation is stable and consistent for existing device models, but it becomes cumbersome to adapt to new device models requiring table rewriting

Engineering Contradiction:

Improvescroll operation consistencyVSAvoiddevice model adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameter from fixed drawing interval time to dynamic calculation based on elapsed time ratio. The moving interval value is calculated as: (elapsed time / moving time) × (end coordinates - start coordinates), allowing the system to adapt to different device models without rewriting fixed tables while maintaining consistent scroll completion times.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent transforms the static fixed drawing interval time table into a dynamic calculation system. Instead of retrieving predetermined values, the system continuously calculates moving interval values based on real-time elapsed time during the scroll operation, enabling flexibility across different device models while maintaining operational consistency.

Inventive Principle:

Principle #15Dynamics

2Speed

If the drawing interval time is shortened to improve scroll responsiveness, then the scroll operation becomes more responsive, but the system complexity increases due to timing synchronization requirements

Engineering Contradiction:

Improvescroll responsivenessVSAvoidtiming synchronization complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent implements feedback by continuously monitoring elapsed time during the scroll operation and using it to dynamically adjust the moving interval value. This feedback mechanism allows the system to maintain high responsiveness while simplifying timing synchronization, as the calculation automatically adapts to actual execution time rather than requiring pre-synchronized fixed intervals.

Inventive Principle:

Principle #23Feedback

AI summary

To provide an information processing device that can perform scroll operations without preparing model-specific tables. An image forming apparatus (1) causes a moving interval calculating part (110) to calculate moving interval values (250) of indication coordinates (320) of an object based on a ratio of an elapsed time (220) to the moving time (200) and a difference between end coordinates (240) and start coordinates (230). A moving interval value after setting wait part (120) adds the moving interval values (250) to the indication coordinates (320) of the object. An object drawing part (130) draws the object on the coordinates to which the moving interval values (250) are added and causes a display part to display the object.
