Method and device for producing a digital image
A method for automatically producing a digital image includes selecting at least one capture mode for capturing at least two image signals from an image capture device. The image capture device captures at least two image signals of the same scene in a RAW format, each image signal being captured according to the image capture mode. A file in a standardized format comprising each image signal and metadata representative of the capture mode is generated and stored. The created file is digitally processed by selecting at least one processing algorithm to process at least two image signals according to the metadata representative of the capture mode, and by fusing at least two image signals according to each chosen image processing algorithm into a fused digital image signal.
1. A method for automatically producing a digital image, comprising steps of:
selecting at least one capture mode to capture at least two raw signals, each raw signal representative of a digital image from an image capture device;
capturing by the image capture device of said at least two raw signals representative of digital images of a same scene in a RAW format, said each raw signal representative of the digital image being captured according to said at least one image capture mode;
generating a file in a standardized format comprising said each raw signal representative of the digital image and metadata representative of said at least one capture mode;
storing the generated file;
digital processing of the generated file by:
selecting at least one processing algorithm to process said at least two raw signals representative of the digital images according to the metadata representative of said at least one capture mode; and
fusing said at least two raw signals representative of the digital images according to said at least one image processing algorithm into a signal representative of a fused digital image.
2. The method as claimed in claim 1 , wherein said at least one capture mode is selected manually by a user of the image capture device or automatically according to at least one of an exposure measurement and a focusing measurement by the image capture device, said at least one capture mode comprising at least one of exposure and focusing parameters for said each raw signal.
3. The method as claimed in claim 1 , wherein said at least one capture mode is selected from at least one element of the following group:
a noise reduction using said at least two raw signals;
a dynamic increase using at said least two raw signals;
an increase or decrease of a depth of field using said at least two raw signals;
an increase in quality at each face using said at least two raw signals in response to a determination that the same scene comprises at least one face; and
a movement breakdown represented in said at least two raw signals.
4. The method as claimed in claim 1 , further comprising a selection step for selecting a raw signal representative of a reference image from said at least two raw signals representative of the digital images captured from the image capture device; and subsequent to the step of capturing, at least one other raw signal representative of an image is fused on said raw signal representative of the reference image.
5. The method as claimed in claim 1 , wherein said at least two raw signals representative of the digital images are captured successively.
6. The method as claimed in claim 1 , wherein the standardized format of the generated file is based on a digital negative (DNG) format.
7. The method as claimed in claim 1 , further comprising a step of transmitting the generated file.
8. A device to automatically produce a digital image, comprising:
an input device to select at least one capture mode to capture at least two raw signals, each raw signal representative of a digital image from an image capture device;
the image capture device configured to capture said at least two raw signals representative of the digital images of a same scene in a RAW format, said each raw signal representative of the digital image being captured according to said at least one image capture mode;
a processor configured to generate a file in a standardized format comprising said each raw signal representative of the digital image and metadata representative of said at least one capture mode;
a storage to store the generated file; and
an image signal processor configured to process the generated file by:
selecting at least one processing algorithm to process said at least two raw signals representative of the digital images according to the metadata representative of said at least one capture mode; and
