Abstract
Proposed are schemes, solutions, concepts, designs, methods and systems pertaining to aiding and/or improving image acquisition from a vibratory personal care device having an image capture device. Embodiments propose generating multiple pulses of illumination during a single vibration cycle of the personal care device. Through illuminating part of the user multiple times during a single vibration cycle of the personal care device, improved images (e.g. images exhibiting less blur and/or distortion) may be obtained. In this way, improved images may be obtained from a vibratory personal care device.
Claims12
A personal care device comprising:
- an image capture device adapted, in use, to capture images of one or more features of a user;
- a vibrator adapted to vibrate the personal care device so that, in use, the personal care device vibrates with a periodic vibration cycle having a vibration frequency;
- an illumination device configured, in use, to generate a pulsed illumination for illuminating part of the user;
- a control unit adapted to control the illumination device to generate two or more pulses of illumination during a single vibration cycle of the personal care device;
- and
- a processor arrangement configured to determine, as a target part of the vibration cycle, first and second portions of the vibration cycle for which the angular velocity of a part of the personal care device meets a predetermined requirement,
- wherein the control unit is adapted to control the illumination device to generate a first pulse of illumination during the first portion of the vibration cycle and to generate a second pulse of illumination during the second portion of the vibration cycle.
A method of controlling a personal care device, wherein the personal care device comprises:
- an image capture device adapted, in use, to capture images of one or more features of a user;
- a vibrator adapted to vibrate the personal care device so that, in use, the personal care device vibrates with a periodic vibration cycle having a vibration frequency;
- and an illumination device configured, in use, to generate a pulsed illumination for illuminating part of the user, and wherein the method comprises:
- determining, as a target part of the vibration cycle, first and second portions of the vibration cycle for which the angular velocity of a part of the personal care device meets a predetermined requirement;
- and,
- controlling the illumination device to generate two or more pulses of illumination during a single vibration cycle of the personal care device,
- wherein control the illumination device comprises controlling the illumination device to generate a first pulse of illumination during the first portion of the vibration cycle and to generate a second pulse of illumination during the second portion of the vibration cycle.
