PERISCOPE-TYPE LENS AND TERMINAL DEVICE

Title:

PERISCOPE-TYPE LENS AND TERMINAL DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/035960

Kind Code:

A1

Abstract:

A periscope-type lens and a terminal device, said periscope-type lens comprising: a filter (210), a reflecting prismatic lens set (220), a zoom lens (230) and a sensor (240); the filter (210) is used for filtering light rays entering from the outside; the reflecting prismatic lens set (220) is used in conjunction with the zoom lens (230) to cause light having passed through the filter (210) to be reflected twice, then to enter the sensor (240). The present periscope-type lens and terminal device reduce the restrictions imposed by the width of a sensor on the thickness of such a lens, such that when using larger sensors and OIS anti-shake technology in order to improve imaging quality, and thereby incurring increases in the peripheral dimensions of sensors, a thinner periscope-type lens can be ensured, providing improved image quality for an identical thickness of such a lens. Terminal devices fitted with the present periscope-type lens provide better image quality and reduced device thickness.
