Description

Technical Field

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards a more convenient and thinner design to provide users with more choices.

[0003] Periscope camera modules offer the advantage of significantly reducing the overall thickness and weight of devices, making them suitable for lightweight designs. A typical periscope camera module consists of two parts: a lens and a prism. The prism is located at the front, while the imaging chip is positioned at the rear of the lens. Light is reflected by the prism, redirecting its path to the lens, where it is then focused before reaching the imaging chip. Due to the complexity of the periscope camera module structure, current technologies cannot implement optical image stabilization, resulting in poor image quality and limiting its application.
