Endoscope Image Compression Dynamic Parameter Adjustment

Solution Overview

Problem

Endoscope systems face challenges in balancing image data compression to reduce power consumption while maintaining high image quality, as large compression ratios degrade image quality and can lead to unstable transmission and prolonged periods of no image display on monitors.

Innovation Solution

An endoscope apparatus with an image pickup device, storage, and processor that continuously adjusts compression parameters based on detected information quantity in the image data, determining whether the information quantity meets a threshold to decide on the display image, ensuring stable transmission and quality by using provisional compression parameters and updating compression settings accordingly.

AI summary

An endoscope apparatus includes a compression processing control unit configured to carry out a compression processing of compressing image data by using a compression parameter to generate compressed data, a monitor that is a display unit configured to display a display image corresponding to the image data, an information quantity detection unit configured to detect a quantity of information on an object contained in the image data, and a judgement unit configured to carry out a judgement processing of judging whether or not a judgement value corresponding to the quantity of information is smaller than a predetermined threshold. The image pickup of the object and the generation of the image data are continuously performed multiple times, and the judgement processing is carried out whenever the image data is generated. The compression parameter and the display image are determined based on a result of the judgement processing.
