Abstract
An imaging system comprises an image sensor configured to detect images, an inertial measurement unit configured to measure movement of the image sensor, a display unit configured to display the images detected by the image sensor, and a control unit. The control unit is configured to control display of the images by the display unit based on the movement measured by the inertial measurement unit. An exemplary variable latency and frame rate camera embodiment is disclosed.
Claims18
An imaging and display system comprising:
- an image sensor configured to controllably detect images and collect image data;
- an inertial measurement unit configured to measure movement of the system and provide multi-axis angular velocity data;
- a display unit configured to controllably display an image stream of the image data;
- and
- a control unit configured to control the image sensor and the display of image stream by the display unit in real-time based on a method of imaging and display using the multi-axis angular velocity data from the inertial measurement unit, said method of imaging and display comprising the steps of:
- collecting the multi-axis angular velocity data from the inertial measurement unit to the control unit,
- determining an amount of motion by the control unit based on the multi-axis angular velocity data,
- adjusting device parameters of the image sensor based on the determined amount of motion by the control unit,
- collecting image data from said image sensor, and
- displaying the image stream by the display unit based on the collected image data.
A variable latency and frame rate camera system comprising:
- a battery pack with a user button capable of powering up the variable latency and frame rate camera system;
- an inertial measurement unit configured to measure movement of the system and provide angular velocity data;
- a control unit to receive said angular velocity data and configure a configuration data set to minimize motion artifacts based on an imaging and display method using a determined angular velocity status in real time;
- an image sensor configured according to said configuration data set to produce a resulting image stream;
- and
- a display unit to receive the resulting image stream and controllably display the resulting image stream for eye level display with minimal motion artifacts, wherein said imaging and display method comprises the steps of:
- collecting inertial measurement unit data from the inertial measurement unit to the control unit,
- determining a measured movement of the system as an amount of movement by the control unit,
- determining by the control unit whether the amount of movement is within one of a set of predetermined ranges, each range being associated with a set of device parameters,
- programming by the control unit a set of device parameters corresponding to the measured movement,
- collecting image data from said image sensor according to the device parameters as set by the control unit, and
- displaying a resulting image stream by the display unit based on the collected image data.
