Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing systems struggle to determine optimal shooting parameters suitable for image processing performed within the capturing apparatus versus external processing apparatus, leading to suboptimal image quality.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shooting parameters are determined for in-apparatus image processing, then image quality is optimized for internal processing, but image quality deteriorates when external processing is used
Solution Approach 1:
The patent implements dynamic adjustment of shooting parameters based on the image processing location. The control unit determines whether image processing will be performed inside or outside the imaging apparatus and automatically adjusts shooting parameters (ISO sensitivity, shutter speed, aperture value) accordingly. This dynamic adaptation resolves the contradiction by making the shooting parameters flexible rather than fixed, allowing optimization for either in-apparatus or external processing scenarios.
Solution Approach 2:
The patent changes shooting parameters (ISO sensitivity, shutter speed, aperture value) based on the determined image processing location. When external processing is detected, the system adjusts these parameters to account for different noise characteristics and processing capabilities of external devices. This parameter adaptation directly resolves the technical contradiction by tailoring the shooting parameters to match the specific processing environment.
2Manufacturing precision
If shooting parameters are determined for external image processing, then image quality is optimized for external processing, but image quality deteriorates when internal processing is used
Solution Approach 1:
The control unit dynamically switches between different sets of shooting parameters depending on whether external or internal image processing is selected. This dynamic parameter selection ensures that the optimal parameter set is always used for the current processing mode, resolving the contradiction between optimization for external processing and compatibility with internal processing.
Solution Approach 2:
The system changes shooting parameters based on the image processing location determination. For external processing, parameters are adjusted to leverage external processing capabilities, while for internal processing, parameters are optimized for the built-in processor. This parameter adaptation resolves the contradiction by making the system versatile across different processing scenarios.
3Reliability
If ISO sensitivity is increased to reduce shutter speed for moving subjects, then camera shake and subject shake effects are reduced, but noise component intensity increases
Solution Approach 1:
The system uses feedback from the determined image processing location to adjust the balance between ISO sensitivity and noise. When external processing is selected, the system anticipates that noise will be reduced post-capture, allowing higher ISO sensitivity to be used without excessive noise in the final image. This feedback-based adjustment resolves the contradiction by considering the downstream noise reduction capability.
Solution Approach 2:
The patent adjusts ISO sensitivity, shutter speed, and aperture value parameters based on the determined image processing location. When external processing is available, the system can increase ISO sensitivity more aggressively because the external processor will reduce noise. This parameter adaptation resolves the contradiction by balancing ISO sensitivity and noise based on the processing capability context.

AI summary
An image capturing apparatus comprises an image sensing unit including an image sensor and configured to capture an image by photoelectric converting an optical image formed on an imaging surface and output an image signal, and a setting unit configured to set shooting parameters to be used at a time of capturing the image by the image sensing unit. The setting unit sets different shooting parameters to be used at the time of capturing the image by the image sensing unit between in a case where it is possible to perform image processing on the image signal by an external image processing apparatus and in a case where it is not possible to perform image processing on the image signal by the external image processing apparatus.
