Abstract
A camera comprises a gain control unit and an exposure control unit. The gain control unit amplifies selected image signals of a first charge image according to a gain profile to generate a second charge image. The exposure control unit analyzes the image signals of the second charge image to adjust an exposure duration or an aperture.
Claims20
A method for managing image signals, comprising:
- amplifying selected image signals of a first charge image according to a gain profile to generate image signals of a second charge image;
- and
- analyzing the image signals of the second charge image to adjust at least one of an exposure duration or an aperture.
A machine executable encoding of a method comprising one or more storage medium having executable encodings stored thereon, which when executed by one or more machines, causes the one or more machines to:
- accumulate an exposure for an image sensor for a duration sufficient to achieve a first exposure level to produce image signals of a first charge image;
- amplify selected image signals of the first charge image according to a gain profile to generate image signals of a second charge image;
- and
- analyze the image signals of the second charge image to adjust the first exposure level by adjusting the accumulation of exposure for the image sensor.
A machine executable encoding of a method comprising one or more storage medium having executable encodings stored thereon, which when executed by one or more machines, causes the one or more machines to:
- expose an image sensor for a duration sufficient to achieve a first exposure level to produce image signals of a first charge image;
- amplify selected image signals of the first charge image according to a gain profile to generate image signals of a second charge image;
- analyze the image signals of the second charge image to adjust the first exposure level;
- and
- adjust the exposure duration to achieve the first exposure level.
