Digital Image Processing Apparatus Automatic Eye Detection Retake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital image processing apparatuses lack the ability to automatically re-photograph an image when a person's eyes are closed, requiring user intervention to check and re-take the picture.
Innovation Solution
A digital signal processing unit within the apparatus detects facial expressions and determines if eyes are closed, automatically re-photographing the image when necessary, utilizing a facial expression detecting unit, a determination unit, and a re-photographing unit to generate a re-photographed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus only captures images without automatic re-photography capability, then the device complexity is low, but the reliability of obtaining clear images with subject eyes open deteriorates
Solution Approach 1:
The system performs preliminary detection of facial expressions and eye states before finalizing the image capture. The digital signal processing unit analyzes the captured image to determine if the subject's eyes are open, and if not, automatically triggers another capture cycle before the user needs to manually intervene.
Solution Approach 2:
The system implements a feedback mechanism where the captured image is analyzed by the digital signal processing unit, which provides feedback about the subject's eye state. Based on this feedback, the system automatically decides whether to retake the image, creating a closed-loop control system that ensures image quality without increasing user burden.
2Productivity
If the apparatus requires manual checking and re-taking of images, then the device complexity is low, but the productivity deteriorates due to repeated user intervention
Solution Approach 1:
The system performs self-service by automatically detecting whether the subject's eyes are open and autonomously deciding to retake the image if necessary. The digital signal processing unit handles the entire process of detection, decision-making, and re-capture without requiring user intervention, making the system serve itself to ensure image quality.
Solution Approach 2:
The system performs preliminary analysis of the captured image to determine if retaking is necessary before the user needs to manually intervene. This preliminary action includes detecting facial expressions and eye states, allowing the system to prepare for potential re-capture and maintain photography efficiency.
3Reliability
If the apparatus adds automatic eye detection and re-photography functionality, then the reliability of obtaining clear images improves, but the ease of operation deteriorates due to increased system complexity
Solution Approach 1:
The system handles the complexity of eye detection and automatic re-photography internally through self-service mechanisms. The digital signal processing unit autonomously performs facial expression detection, eye state determination, and decides when to retake images, shielding the user from the underlying complexity while ensuring image quality.
Solution Approach 2:
The system performs preliminary detection and analysis of eye states before the user needs to take any action. By completing the detection and decision-making process in advance, the system maintains ease of operation as users only need to capture images without worrying about eye detection or manual retaking.

AI summary
Provided are a digital image processing apparatus and a method of controlling the same. The digital image processing apparatus includes a digital signal processing unit that recognizes a facial expression of a face from a photographed image, determines whether the eyes of the subject's face are closed, and re-photographs the image when the eyes are closed. The method of controlling the digital image processing apparatus includes: (a) receiving an image; (b) generating a photographed image by photographing the image; (c) checking whether the eyes on a face photographed on the photographed image are closed; and (d) generating a re-photographed image by re-photographing the image when the eyes are closed.
