AI Technical Summary
Technical Problem
During optical image stabilization, the lens does not have enough time to return to its initial position, resulting in poor image stabilization performance.
Method used
By predicting the image area of the unexposed image frame, the output time of the first pixel row and the second pixel row is determined, and the drive is controlled to perform optical image stabilization at the first time and return to the initial position at the second time.
Benefits of technology
It extends the time it takes for the lens to return to its initial position, thus improving image stabilization during shooting.
