Imaging Apparatus Adaptive Sensitivity for Object Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses face challenges in reducing image quality degradation due to camera shake and object shake, leading to poor photography results, as photographers struggle to accurately assess the moving speed of objects and adjust sensitivity settings accordingly.
Innovation Solution
An imaging apparatus with a face detection section that performs continuous shooting for multiple objects based on detected faces, using a control section to adjust camera shake correction and sensitivity settings dynamically, ensuring optimal photography conditions for each object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If photographing sensitivity is increased to prevent camera shake, then image stability is improved, but noise in the image increases
Solution Approach 1:
The system dynamically changes the photographing sensitivity parameter based on detected object motion. When object shake is detected, sensitivity is increased to use faster shutter speeds; when no object shake is detected, sensitivity is reduced to minimize noise. This resolves the contradiction by making sensitivity adaptive rather than fixed.
Solution Approach 2:
The invention introduces dynamic adjustment of photographing sensitivity based on real-time detection of object motion. The control section modifies sensitivity settings in response to changing conditions, transforming a static parameter into a dynamic one that adapts to prevent camera shake only when necessary, thereby avoiding unnecessary noise.
2Reliability
If shutter speed is increased to prevent object shake, then image quality is improved, but photographing sensitivity must be increased which amplifies noise
Solution Approach 1:
The system changes the shutter speed parameter dynamically based on object motion detection. When object shake is detected, shutter speed is increased to freeze motion; when no object shake is detected, shutter speed is reduced to allow longer exposure without noise amplification. This resolves the contradiction by making shutter speed adaptive.
Solution Approach 2:
The invention makes shutter speed a dynamic parameter that adjusts in response to detected object motion. The control section increases shutter speed only when object shake is detected, and reduces it when no object shake is present, thereby achieving high image quality only when necessary while minimizing noise amplification from sensitivity increases.
3Reliability
If photographers manually adjust sensitivity settings to prevent object shake, then image quality can be maintained, but operation complexity increases and photographers may miss shooting opportunities
Solution Approach 1:
The system performs self-service by automatically detecting object shake and adjusting photographing parameters without user intervention. The detection section identifies object motion, and the control section automatically modifies sensitivity and shutter speed settings, freeing the photographer from manual adjustments and ensuring optimal settings are applied instantly.
Solution Approach 2:
The invention implements a feedback loop where the detection section continuously monitors object motion and provides information to the control section, which adjusts parameters accordingly. This closed-loop system automatically responds to changing conditions, maintaining image quality without requiring photographer intervention or complex manual operations.

AI summary
Digital camera is provided with face detection section that detects faces of a plurality of photographing objects, microcomputer performs continuous shooting in optimum photographing conditions in accordance with the number of faces of the photographing objects for each face of the plurality of photographing objects by a single shutter operation and performs control by assigning serial photographing object numbers to the images of the plurality of photographing objects taken by continuous shooting and recording the images in a single continuous-shooting image folder. Furthermore, microcomputer performs continuous shooting in predetermined order in accordance with the number of faces of the photographing objects and detects, when the photographing object speed is equal to or higher than a predetermined value, the photographing object speed again after photographing other photographing objects.
