DEFECTIVE PIXEL CORRECTION DEVICE AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240334084 titled 'DEFECTIVE PIXEL CORRECTION DEVICE AND METHOD OF OPERATING THE SAME
The abstract describes a defective pixel correction device that includes a pixel grading circuit, a pixel selection circuit, and a correction circuit to correct defective pixels in an input image based on their defect levels.
- Pixel grading circuit outputs a grade map with grades indicating defect levels for pixels in the input image.
- Pixel selection circuit selects candidate pixels for correction based on the defect levels in the grade map.
- Correction circuit corrects the selected candidate pixels to improve image quality.
Potential Applications: - Image processing in digital cameras - Video editing software - Medical imaging devices
Problems Solved: - Correcting defective pixels in images - Improving overall image quality
Benefits: - Enhanced image quality - Increased accuracy in image processing
Commercial Applications: Title: "Advanced Defective Pixel Correction Device for Image Enhancement" This technology can be used in various industries such as photography, medical imaging, and video production to improve image quality and accuracy in image processing.
Questions about Defective Pixel Correction Device: 1. How does the pixel grading circuit determine the defect levels of pixels in the input image? The pixel grading circuit analyzes the characteristics of each pixel to assign a grade indicating its defect level.
2. What criteria does the pixel selection circuit use to choose candidate pixels for correction? The pixel selection circuit selects candidate pixels based on whether their defect levels correspond to a correction level in the grade map.
Original Abstract Submitted
a defective pixel correction device is provided. the defective pixel correction device includes: a pixel grading circuit configured to output a grade map including a plurality of grades indicating defect levels and respectively corresponding to a plurality of pixels included in an input image; a pixel selection circuit configured to select one or more candidate pixels from among the plurality of pixels, based on whether the plurality of grades correspond to a correction level, in the grade map; and a correction circuit configured to correct the one or more candidate pixels.
