Back-End Scaling Circuit With Local Tone Mapping After Image Warping - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240297949 titled 'Back-End Scaling Circuit With Local Tone Mapping After Image Warping
The abstract describes an image processing circuit that performs local tone mapping (LTM) after image warping. The circuit includes a warping circuit that warps an input image to generate a warped image, and a LTM circuit coupled to the warping circuit. The LTM circuit determines input and output color component values for pixels in the warped image, calculates gain values based on mapping of pixel coordinates, and adjusts color component values to generate an output image.

Questions about Image Processing Circuit for Local Tone Mapping after Image Warping:
1. How does the LTM circuit calculate gain values for adjusting color component values? The LTM circuit calculates gain values as a ratio of the output color component value relative to the input color component value for each pixel.
2. What are the key differences between local tone mapping and global tone mapping techniques? Local tone mapping focuses on adjusting tone values in specific regions of an image, while global tone mapping applies adjustments to the entire image uniformly.
Original Abstract Submitted
an image processing circuit for performing local tone mapping (ltm) after image warping. the image processing circuit includes a warping circuit that warps an input image to generate a warped image, and a ltm circuit coupled to the warping circuit. the ltm circuit determines an input color component value for a color component of a pixel in a version of the warped image, determines an output color component value for the color component of the pixel, based on mapping of coordinates of pixels in the warped image to coordinates of pixels in the input image, determines a gain value for the pixel as a ratio of the output color component value relative to the input color component value, and adjusts color component values for color components of the pixel using the gain value to generate adjusted color component values for the color components of the pixel in an output image.
