Abstract
There is provided an optical navigation device including a light sensor and a processor. The light sensor is configured to capture image frames using a predetermined frame period. The processor is configured to calculate image statistics according to a first image frame captured by the light sensor and determine an expected shutter interval for capturing a second image frame according to the image statistics. The processor is further configured to control the light sensor to capture additional shutter tuning frames between the first image frame and the second image frame upon confirming a mode transition at or prior to the first image frame.
