IMAGE SIGNAL PROCESSOR AND IMAGE SENSING DEVICE THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18513871 titled 'IMAGE SIGNAL PROCESSOR AND IMAGE SENSING DEVICE THEREOF
The patent application describes an image sensing device that corrects bad pixels in captured images through a local saturation threshold process.
- Image sensor captures raw image of subject
- Image signal processor corrects bad pixels patch-by-patch
- Compares pixel values with local saturation threshold
- Determines local saturation state based on number of saturated pixels
- Outputs corrected image patch based on saturation state
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Correcting bad pixels in captured images - Improving image quality and accuracy
Benefits: - Enhanced image quality - Improved accuracy in image processing - Reduction of visual defects in images
Commercial Applications: Title: "Advanced Image Correction Technology for Enhanced Image Quality" This technology can be utilized in various industries such as photography, security, and healthcare for improved image processing and quality control.

Questions about Image Sensing Device: 1. How does the local saturation threshold process improve image quality? 2. What are the potential limitations of the image sensing device in correcting bad pixels?
Original Abstract Submitted
An image sensing device including an image sensor configured to output a raw image by capturing an image of a subject and an image signal processor configured to perform a bad pixel correction process on the raw image on an image patch-by-image patch unit, compare pixels of an image patch of the raw image with a local saturation threshold value, determine a state of local saturation of the image patch based on a number of saturated pixels whose pixel values exceed the local saturation threshold value, and output a corrected image patch, which is obtained by correcting a pixel of the image patch with a corrected pixel value, with a replacement pixel value, or with a raw pixel value depending on the state of local saturation of the image patch.
