Patent ID: 8466976

Claim:
A method for producing a high-dynamic-range image, comprising: a) receiving a low-resolution image of a scene having a first resolution and captured at a first exposure level; b) receiving a high-resolution image of the scene having a second resolution and captured at a second exposure level different from the first exposure level, the second resolution being greater than the first resolution; c) using a data processor to form a representative low-resolution image from the high-resolution image; d) using a data processor to form a residual image corresponding to differences between the high-resolution image and the representative low-resolution image; e) using a data processor to form a low-resolution high-dynamic range image by combining the low-resolution image and the representative low-resolution image; f) using a data processor to produce the high-dynamic-range image by combining the low-resolution high-dynamic-range image and the residual image; and g) storing the high-dynamic-range image in a processor accessible memory.
