Abstract
An image capture device includes a light source, an image capture circuit, and a processor. The light source is used for generating emitting light. The image capture circuit is used for capturing an image corresponding to the emitting light. The processor is coupled to the light source and the image capture circuit for optionally adjusting the intensity of the emitting light of the light source according to luminance corresponding to the image and a target value.
Claims14
An image capture device, comprising:
- a light source generating emitting light;
- an image capture circuit capturing an image corresponding to the emitting light;
- and
- a processor coupled to the image capture circuit and the light source for optionally adjusting intensity of the emitting light of the light source according to a percentage of the image occupied by an area corresponding to a maximum luminance value of at least one luminance value within the image to make an adjusted maximum luminance value be close to a target value.
An operation method of an image capture device, wherein the image capture device comprises a light source, an image capture circuit, and a
- processor, the operation method comprising:
- the light source generating emitting light;
- the image capture circuit capturing an image corresponding to the emitting light;
- and
- the processor optionally adjusting intensity of the emitting light of the light source according to a percentage of the image occupied by an area corresponding to a maximum luminance value of at least one luminance value within the image to make an adjusted maximum luminance value be close to a target value.
