AI Technical Summary

Technical Problem

Existing image processing technologies face challenges in improving visibility while reducing noise, particularly during real-time video shooting, due to high processing loads and delays in noise reduction (NR) processing, especially when adjusting focus manually.

Method used

An image processing apparatus that switches between first and second noise reduction processes based on imaging condition adjustments, such as focus changes, to minimize delay time and processing load, using a determination unit to assess focus adjustments and a mode switching unit to select appropriate NR processing modes.

Benefits of technology

Reduces noise reduction processing delays, allowing for real-time imaging with improved visibility by selectively applying NR processing, especially on partial regions, thus facilitating accurate focus adjustments.

Abstract

The present invention provides an image processing device that enables imaging while performing NR (Noise Reduction) processing with settings desired by the user, while reducing the delay time of noise reduction processing. [Solution] The image captured by the imaging device is acquired. It is determined whether or not the imaging conditions of the imaging device are being adjusted. The noise in the image is reduced. The process for reducing the noise in the image is switched to a first reduction process if the imaging conditions of the imaging device are not being adjusted, and to a second reduction process that has a shorter delay time between image input and output in the noise reduction process than the first reduction process if the imaging conditions of the imaging device are being adjusted.
