Abstract
In one implementation, a method of compensating for motion blur while presenting content on a display of an electronic device through display actuation is disclosed. The method involves detecting movement of the electronic device using a sensor of the electronic device while presenting content on a display of the electronic device. An inter-frame movement of the electronic device is determined based on the movement of the electronic device. The display is moved using an actuator of the electronic device that is coupled to the display such that movement of the display opposes the inter-frame movement of the electronic device.
Claims20
A method comprising:
- at an electronic device with a display, a sensor, and an actuator coupled to the display:
- detecting movement of the electronic device using the sensor while presenting content on the display;
- determining an inter-frame movement of the electronic device based on the movement of the electronic device;
- and
- moving the display using the actuator in synchrony with a duty cycle of the display such that the display is moved:
- in a first direction such that movement of the display opposes the inter-frame movement of the electronic device while activated pixels of the display are illuminated;
- and
- in a second direction, opposite the first direction, while the activated pixels are not illuminated.
An electronic device comprising:
- a display;
- a processor configured to determine a translation vector using data corresponding to movement of the electronic device, the translation vector defining inter-frame movement of a pixel of the display;
- and
- an actuator device that is coupled to the display and configured to move the display in synchrony with a duty cycle of the display and based on the translation vector such that the display is moved:
- in a first direction such that movement of the display opposes the movement of the electronic device while activated pixels of the display are illuminated;
- and
- in a second direction, opposite the first direction, while the activated pixels are not illuminated.
An electronic device comprising:
- a sensor configured to detect movement of the electronic device;
- a processor configured to determine a translation vector based on the movement of the electronic device, the translation vector defining a displacement of the electronic device in a ground reference frame between a first time and a second time subsequent to the first time;
- and
- an actuator device that is coupled to the display and configured to move the display in synchrony with a duty cycle of the display and based on the translation vector such that the display is moved:
- in a first direction such that movement of the display opposes the movement of the electronic device while activated pixels of the display are illuminated;
- and
- in a second direction, opposite the first direction, while the activated pixels are not illuminated.
