Björn Östby

Title: Björn Östby: Video and Monitoring Innovations.

Introduction

Björn Östby is an inventor associated with Axis AB in Lund, Sweden. His patent work addresses video encoding and temperature compensation in monitoring devices. The supplied information lists 2 patents.

Latest Patents

Östby’s listed patents include “Video Encoding Method and Video Encoder System.” The invention adapts video compression and group-of-pictures (GOP) length according to measured light and motion levels. When light falls below a specified threshold, the method uses a predetermined GOP length and adjusts compression based on the light level. Above that threshold, it adjusts GOP length according to motion and compression according to light.

His other listed patent, “Trend-Based Temperature Compensation for a Monitoring Device,” describes adjusting a focus motor after detecting a significant temperature change. The device retrieves a trend-based motor position setting from memory and selects a starting position using that setting or the current motor position. It then applies a just-noticeable-difference modification and selects a temperature-adjusted motor position based on the result.

Career Highlights

The available information connects Östby’s inventions with Axis AB and monitoring technology. His listed patent topics reflect work on video encoding and focus adjustment under changing temperature conditions.
