Method for obtaining at least one high dynamic range image, and corresponding computer program product, and electronic device

A computer-readable and non-transient storage medium storing a computer program comprising a set of computer-executable instructions to implement a method for obtaining at least one high dynamic range image when the instructions are executed by a computer, wherein the instructions comprise instructions, which when executed, configure the computer to perform a method for obtaining at least one high dynamic range image via aligning and fusion of at least two low dynamic range images, wherein said method for obtaining comprises:

• obtaining a first low dynamic range image, said first low dynamic range image comprising several color components in a color space;
• obtaining a second low dynamic range image in said color space, comprising, for at least one component color, at least a part of pixels of said second low dynamic range image, defining a region, for which Euclidean distance between a value of a pixel in said region in said second low dynamic range image and a value of a corresponding pixel in said region in said first low dynamic range image is below a threshold;
• and
• said aligning comprising matching features obtained from said at least one component color of said first low dynamic range image and from said at least one component color of said second low dynamic range image.

An electronic device configured to obtain at least one high dynamic range image via a first module configured to align at least two low dynamic range images and a second module configured to perform a fusion of said at least two low dynamic range images, said electronic device being wherein it comprises:

• a third module configured to obtain a first low dynamic range image, said first low dynamic range image comprising several color components in a color space;
• a fourth module configured to obtain a second low dynamic range image in said color space, comprising, for at least one component color, at least a part of pixels of said second low dynamic range image, defining a region, for which Euclidean distance between a value of a pixel in said region in said second low dynamic range image and a value of a corresponding pixel in said region in said first low dynamic range image is below a threshold;
• and
• said first module comprising for a fifth module configured to match features obtained from said at least one component color of said first low dynamic range image and from said at least one component color of said second low dynamic range image.
