MEMS-BASED APERTURE AND SHUTTER |
摘要 |
<p>Some embodiments comprise at least one array that includes microelectromechanical systems ("MEMS")-based light-modulating devices. Elements of the array(s) may be configured to absorb and/or reflect light when in a first configuration and to transmit light when in a second position. Such an array may be controlled to function as a camera aperture and/or as a camera shutter. For example, a controller may cause the array to function as a shutter by causing the MEMS devices to open for a predetermined period of time. The predetermined period of time may be based, at least in part, on input received from a user, the intensity of ambient light, the intensity of a flash, the size of the camera aperture, etc. Some embodiments provide a variable aperture device that does not add significant thickness or cost to a camera module. Such embodiments may enable a camera to function well in both bright and dark light, to control depth of field, etc.</p> |
