Abstract
An image capture device includes an image sensor for capturing image data of a scene, and a display screen for displaying a preview of the captured image of the scene. Additionally, the image capture device includes a photovoltaic solar cell for outputting electrical energy responsive to environmental lighting conditions. A control section determines whether the image capture device is or is not currently being used in a bright environment. Responsive to a determination that the image capture device is currently being used in a bright environment, the control section increases brightness of the display screen, and switches electrical energy outputted from the photovoltaic cell for use by the display screen.
Claims28
An image capture device comprising:
- an image sensor for capturing image data of a scene;
- a display screen for displaying a preview of the captured image of the scene;
- a photovoltaic solar cell for outputting electrical energy responsive to environmental lighting conditions;
- and
- a control section constructed to determine whether the image capture device is or is not currently being used in a bright environment,
- wherein responsive to a determination that the image capture device is currently being used in a bright environment, the control section increases brightness of the display screen and switches electrical energy outputted from the photovoltaic cell for use by the display screen.
A method for an image capture device, comprising:
- capturing image data of a scene with an image sensor;
- displaying a preview of the captured image of the scene on a display screen;
- outputting electrical energy responsive to environmental lighting conditions, wherein the electrical energy is output by a photovoltaic solar cell;
- and
- determining whether the image capture device is or is not currently being used in a bright environment,
- wherein responsive to a determination that the image capture device is currently being used in a bright environment, the brightness of the display screen is increased, and electrical energy outputted from the photovoltaic cell is switched for use by the display screen.
An image processing module for an image capture device, comprising:
- a capture module for capturing image data of a scene with an image sensor;
- a preview display module for displaying a preview of the captured image of the scene on a display screen;
- an energy output module for managing electrical energy output in response to environmental lighting conditions, wherein the electrical energy is output by a photovoltaic solar cell;
- and
- a determination module for determining whether the image capture device is or is not currently being used in a bright environment,
- wherein responsive to a determination that the image capture device is currently being used in a bright environment, the brightness of the display screen is increased, and electrical energy outputted from the photovoltaic cell is switched for use by the display screen.
A computer-readable storage medium storing computer-executable process steps for an image capture device, for performing a method for enhancing a preview image, the method comprising:
- capturing image data of a scene with an image sensor;
- displaying a preview of the captured image of the scene on a display screen;
- outputting electrical energy responsive to environmental lighting conditions, wherein the electrical energy is output by a photovoltaic solar cell;
- and
- determining whether the image capture device is or is not currently being used in a bright environment,
- wherein responsive to a determination that the image capture device is currently being used in a bright environment, the brightness of the display screen is increased, and electrical energy outputted from the photovoltaic cell is switched for use by the display screen.
