IMAGE SIGNAL PROCESSOR, OPERATING METHOD OF THE IMAGE SIGNAL PROCESSOR, AND APPLICATION PROCESSOR INCLUDING THE IMAGE SIGNAL PROCESSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 17970272 titled 'IMAGE SIGNAL PROCESSOR, OPERATING METHOD OF THE IMAGE SIGNAL PROCESSOR, AND APPLICATION PROCESSOR INCLUDING THE IMAGE SIGNAL PROCESSOR

Simplified Explanation

The abstract describes an image signal processor that includes various circuits and engines to process image signals and generate an output image signal. It also includes a correction information generating circuit to extract information on image quality loss and a recomposition circuit to generate the final output image signal.

• The image signal processor downscales an input image signal and performs multiple image processing operations on it.
• It includes two upscaling circuits to upscale the processed image signal and the original downscaled image signal.
• A correction information generating circuit extracts information on image quality loss from the input and upscaled image signals.
• A recomposition circuit combines the upscaled image signal and the extracted image information to generate the final output image signal.

Potential Applications

• This technology can be used in digital cameras, smartphones, and other devices that require image processing.
• It can improve the image quality and resolution of captured or displayed images.
• The image signal processor can be integrated into application processors for efficient image processing.

Problems Solved

• The image signal processor addresses the problem of image quality loss during downscaling and upscaling processes.
• It solves the issue of maintaining image quality while performing multiple image processing operations.
• The correction information generating circuit helps identify and compensate for any image quality loss.

Benefits

• The image signal processor provides improved image quality and resolution.
• It allows for efficient image processing with multiple operations.
• The correction information generating circuit helps maintain image quality and compensate for any loss during upscaling.

Original Abstract Submitted

Provided are an image signal processor, an operating method of the image signal processor, and an application processor including the image signal processor. The image signal processor includes a downscaling circuit configured to generate a first image signal by downscaling an input image signal; an image processing engine configured to generate a second image signal by performing a plurality of image processing operations on the first image signal; a first upscaling circuit configured to generate a third image signal by upscaling the second image signal; a second upscaling circuit configured to generate a fourth image signal by upscaling the first image signal; a correction information generating circuit configured to generate an image information signal by extracting information on image quality loss of the third image signal from the input image signal and the fourth image signal; and a recomposition circuit configured to generate an output image signal by recomposing the third image signal and the image information signal.
