Abstract

A portable electronic device with image capturing capabilities automatically or semi-automatically adjusts one or more image capturing parameters based on an input attribute of user engagement with a single-action haptic input mechanism. For example, the duration for which a single-action control button carried on a frame of the device is pressed automatically determines an image stabilization mode for on-board processing of captured image data. In one example, an above-threshold press duration automatically activates a less rigorous image stabilization mode, while button release before expiry of the threshold automatically activates a more rigorous photo stabilization mode.

Claims

1. A portable electronic device comprising:

a frame;

a camera mounted on the frame and configured to capture and process image data according to a plurality of image capture parameters;

an input mechanism provided on the frame and configured for receiving user input to control operation of the camera, the input mechanism being disposable by a user between an engaged condition and a disengaged condition; and

a camera controller incorporated in the frame and configured to automatically adjust one or more of the plurality of image capture parameters of the camera based at least in part on an activation duration indicating a duration for which the input mechanism is disposed to the engaged condition during user engagement with the input mechanism, the one or more automatically adjusted image capture parameters including an image stabilization parameter adjustable by the camera controller between a first mode and a second mode on-board image stabilization at the portable electronic device during image capture being more resource intensive in the first mode than in the second mode.

2. The portable electronic device of claim 1, wherein the input mechanism comprises a control button carried by the frame of the portable electronic device, such that disposal of the input mechanism to the engaged condition comprises pressing of the control button by the user, the activation duration indicating a period for which the control button is continuously pressed by the user.

3. The portable electronic device of claim 2, wherein the control button is the only mechanism incorporated in the frame for receiving manual user input to control functioning of the camera.

4. The portable electronic device of claim 1, wherein the portable electronic device is an article of eyewear, the frame being head-mountable for carrying one or more optical elements within a field of view of the user.

5. The portable electronic device of claim 1, wherein the image stabilization parameter is adjustable between a video stabilization mode and a photo stabilization mode.

6. The portable electronic device of claim 1, wherein the camera controller is further configured to:

determine whether the activation duration exceeds a predefined threshold interval;

in response to determining that the activation duration exceeds the threshold interval, cause disposal of the image stabilization parameter to the second mode; and

in response to determining that the activation duration is less than the threshold interval, causing disposal of the image stabilization parameter to the first mode.

7. A method comprising:

detecting a user engagement with an input mechanism forming part of a portable electronic device having an on-board camera configured to capture and process image data according to a plurality of image capture parameters, the user engagement comprising disposal of the input mechanism from a disengaged condition to an engaged condition;

identifying an activation duration indicating a duration for which the input mechanism is disposed to the engaged condition during the user engagement; and

using one or more computer processor devices incorporated in the portable electronic device, automatically adjusting one or more of the plurality of image capture parameters based at least in part on the activation duration, the one or more automatically adjusted image capture parameters including an image stabilization parameter adjustable between a first mode and a second mode, on-board image stabilization at the portable electronic device during image capture being more resource intensive in the first mode than in the second mode.

8. The method of claim 7, wherein the input mechanism comprises a control button provided on the portable electronic device, such that disposal of the input mechanism to the engaged condition comprises pressing of the control button by a user, the activation duration indicating a period for which the control button is continuously pressed by the user.

9. The method of claim 8, wherein the control button is the only mechanism incorporated in the portable electronic device for receiving manual user input to control functioning of the camera.

10. The method of claim 7, wherein the image stabilization parameter is adjustable between a video stabilization mode and a photo stabilization mode.

11. The method of claim 7, wherein the automatically adjusting the one or more image capture parameters comprises:

determining whether the activation duration exceeds a predefined threshold interval; and

in response to determining that the activation duration is less than the threshold interval, causing disposal of the image stabilization parameter to the first mode.

12. A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a machine, cause the machine to perform operations comprising:

detecting a user engagement with an input mechanism forming part of a portable electronic device having an on-board camera configured to capture and process image data according to a plurality of image capture parameters, the user engagement comprising disposal of the input mechanism from a disengaged condition to an engaged condition;

identifying an activation duration indicating a duration for which the input mechanism is disposed to the engaged condition during the user engagement; and

using one or more computer processor devices incorporated in the portable electronic device, automatically adjusting one or more of the plurality of image capture parameters based at least in part on the activation duration, the one or more automatically adjusted image capture parameters including an image stabilization parameter adjustable between a first mode and a second mode, on-board image stabilization at the portable electronic device during image capture being more resource intensive in the first mode than in the second mode.
