DIGITAL IMAGING SYSTEM WITH REFOCUSABLE IMAGING MODE

摘要

A digital imaging system switchable between a low-resolution refocusable imaging mode and a high-resolution non-refocusable imaging mode comprising: an image sensor having a plurality of sensor pixels for capturing a digital image; an imaging lens for forming an image of a scene onto an image plane; and a switchable optical module including a microlens array module having a microlens array with a plurality of microlenses, and a glass plate module; wherein when the digital imaging system is switched to be in the low-resolution refocusable mode the switchable optical module positions the microlens array module between the imaging lens and the image sensor, and when the digital imaging system is switched to be in the high-resolution non-refocusable mode the switchable optical module positions the glass plate module between the imaging lens and the image sensor.
