Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing characteristics are applied according to object size, then appropriate effects are achieved, but the characteristics change when object size changes causing user discomfort
Solution Approach 1:
The patent applies dynamics by making the image processing characteristics changeable according to optical system conditions. Specifically, the aberration characteristics are dynamically adjusted based on zoom ratio, aperture value, and focus position, allowing the system to adapt to different shooting scenarios while maintaining consistent visual effects for the user.
Solution Approach 2:
The patent implements parameter changes by modifying image processing characteristics based on optical parameters such as zoom ratio, aperture value, and focus position. When these optical parameters change, the system automatically adjusts the aberration characteristics to maintain appropriate image processing effects without causing user discomfort.
2Measurement precision
If beautiful-skin processing is applied based on face detection, then skin effect is improved, but blurring becomes noticeable when face size is small
Solution Approach 1:
The patent applies local quality by differentiating image processing based on the size of the detected subject. When a small face is detected, the system adjusts the processing strength to avoid excessive blurring, while maintaining skin beautification effects. This allows different processing characteristics to be applied to different regions or subjects based on their size.
3Measurement precision
If flare reproduction is applied to all images, then flare effect is achieved, but the effect is too strong or too weak depending on object size
Solution Approach 1:
The patent implements parameter changes by adjusting flare reproduction intensity based on object size detection. When a small object is detected, the system automatically reduces the flare effect strength to maintain appropriateness, while preserving the flare reproduction capability for larger objects where the effect is more suitable.

AI summary
An image processing apparatus includes a memory storing instructions, and a processor configured to execute the instructions to acquire information about an object size in first image data, acquire a parameter about an optical characteristic of an optical system, acquire, based on the parameter, a characteristic that changes according to the information about the object size, and generate second image data by applying the characteristic to the first image data. The parameter changes according to at least one of states of zoom, focus, and an aperture stop of the optical system. The processor is configured to change processing according to whether it is determined that the at least one state has changed.
