IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17975287 titled 'IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
Simplified Explanation
The patent application describes an image processing apparatus that corrects bokeh (blurred background) caused by the characteristics of an imaging optical system used to capture an image. It also adds a predetermined effect to high luminance portions of the image that meet certain conditions.
- The image processing apparatus corrects bokeh caused by aberrations in the optical system while preserving bokeh as a photographic expression.
- It applies image restoration processing to the input image to correct the bokeh caused by the optical system.
- It further adds a predetermined effect to high luminance portions of the image that satisfy a predetermined condition.
- The apparatus aims to improve the overall quality and aesthetic appeal of the image by correcting bokeh and enhancing certain areas.
Potential Applications
This technology can be applied in various fields where image processing is required, such as:
- Photography: Enhancing the quality of images by correcting bokeh caused by optical system characteristics and adding effects to specific areas.
- Advertising: Creating visually appealing images with corrected bokeh and enhanced high luminance portions.
- Art and Design: Allowing artists and designers to manipulate and enhance images to achieve desired visual effects.
Problems Solved
The image processing apparatus addresses the following problems:
- Bokeh correction: Correcting bokeh caused by the characteristics of the imaging optical system, such as aberrations, to improve the overall image quality.
- Maintaining photographic expression: Preserving bokeh as a desirable photographic effect while correcting any undesirable bokeh caused by optical system characteristics.
- Enhancing specific areas: Adding effects to high luminance portions of the image that meet certain conditions to enhance their visual impact.
Benefits
The use of this image processing apparatus offers several benefits:
- Improved image quality: Correcting bokeh caused by optical system characteristics results in sharper and more visually appealing images.
- Preserved photographic expression: The apparatus maintains the desired bokeh effect while correcting any unwanted bokeh caused by optical system aberrations.
- Enhanced visual impact: Adding effects to high luminance portions of the image enhances their visual appeal, making them stand out more effectively.
Original Abstract Submitted
An image processing apparatus applies, to an input image, image restoration processing for correcting bokeh caused by a characteristic of an imaging optical system used to capture the input image. The image processing apparatus may further add a predetermined effect to a high luminance portion satisfying a predetermined condition in the input image to which the image restoration processing has been applied. The image processing apparatus has capabilities both correcting bokeh caused by an aberration in an optical system while keeping bokeh as photographic expression.
