Solution Overview

Problem

Users face difficulties in recognizing and adjusting to achieve desired photography conditions when capturing images with devices having photography functions, such as smartphones, as it is challenging to determine deviations from optimal image capture settings, especially for applications like iris authentication.

Innovation Solution

An image processing apparatus and method that includes an image acquisition section, an image determination section, a deformation processing section, and a display section, which calculates and displays a deformed image to guide users in adjusting their device settings to meet desired photography conditions by highlighting deviations from optimal image capture settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users capture images using photography function apparatuses, then images can be obtained for various applications, but users cannot recognize deviations from desired photography conditions

Engineering Contradiction:
Improvephotography condition accuracyVSAvoiddeviation recognition difficulty
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The system captures a photographed image and generates a generated image that provides visual feedback to the user about the current photography condition. By comparing the photographed image with the generated image, users can recognize deviations from desired conditions (such as eye position, opening state, or image quality) and adjust accordingly, thus resolving the difficulty of detecting photography condition deviations.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If users attempt to adjust photography conditions without guidance, then they may eventually achieve desired conditions, but the process becomes time-consuming and difficult

Engineering Contradiction:
Improvephotography adjustment easeVSAvoidadjustment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system provides real-time visual feedback by generating and displaying a generated image that shows users exactly how their photographed image deviates from desired conditions. This immediate feedback eliminates trial-and-error adjustment, making it easier and faster for users to achieve correct photography conditions such as proper eye positioning and opening state.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The generated image acts as an intermediary between the photographed image and the user, translating complex photography condition deviations into visual information that users can easily understand and act upon, thereby simplifying the adjustment process.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information processing system includes circuitry that inputs an image, and determines whether the image deviates from at least one desired image capture condition. The circuitry identifies a deviation amount of the image relative to the at least one desired image capture condition, and generates a deformed image in which a deviation from the at least one desired image capture condition is increased by a predetermined amount over the deviation amount identified.
