The present invention relates to a method and system for obtaining a point spread function for deblurring image data captured by an imaging device comprising a motion sensor. First, motion path values indicating the motion of the imaging device during the exposure time are acquired. The motion path values of the imaging device are then projected onto the sensor plane and for each sensor pixel the projected motion path values are integrated over time. Said integrated value represents for each sensor pixel an initial estimate of the point spread function. Optionally, the size of the point spread function can also be estimated based on the distance of the focused object and taken into account during the projecting step.

A whiteboard view camera, which in one embodiment is mounted on a boom, which is fixed above the whiteboard. However, the whiteboard view camera can also be wall or table mounted. The whiteboard view camera differs from an ordinary camera by allowing the lens to tilt with respect to the sensor plane, and shift with respect to the central ray. When the tilt angle α is zero, then the resolution of whiteboard is uniform (e.g., the top and bottom of the whiteboard have the same resolution). In addition, the focus plane is equal to the whiteboard plane, so depth of field issues are not a problem (e.g., a large aperture can be used). Hence, no image noise is introduced. A key contribution of the whiteboard view camera configuration according to the invention is the use of a view camera to capture whiteboard images at uniform resolutions. One embodiment of the whiteboard view camera employs a microphone array of the invention and uses a computer to optimize the image data and audio signals.

Provided herein are sondes having a pressure sensor that is separated from active sensing portions of the other sonde sensor or sensors by a longitudinal distance along the sonde. The pressure sensor may be positioned in the base portion of the sonde, with removable sensors connected thereto with a sensor plane at a distal end of the sensors that measures any number of parameters associated with the liquid in which the sonde is immersed. An orientation sensor positioned in the base portion determines an orientation angle of the sonde that, in combination with the depth determined at the pressure sensor location by the pressure sensor, provides the ability to determine the actual depth of the sensor plane, irrespective of orientation angle. Accordingly, improved depth measurement is achieved, without having to confine placement of the pressure sensor at the sensor plane.
