Apparatus and method for detail enhancement in super-resolution imaging using mobile electronic device

An electronic device comprising:

• at least one camera;
• and
• at least one processing device configured to obtain multiple image frames of a scene and process the multiple image frames of the scene to generate a higher-resolution image of the scene;
• wherein, to process the multiple image frames of the scene, the at least one processing device is configured to:
• generate an initial estimate of the scene based on the multiple image frames of the scene;
• in each of multiple iterations, (i) generate a current estimate of the scene based on the multiple image frames of the scene and a prior estimate of the scene and (ii) regularize the generated current estimate of the scene, the regularized current estimate of the scene from one iteration representing the prior estimate of the scene in a subsequent iteration;
• and
• continue the iterations until the estimates of the scene converge on the higher-resolution image of the scene;
• and
• wherein, to generate the initial estimate of the scene, the at least one processing device is configured to warp at least some of the multiple image frames to align the image frames.

A non-transitory machine-readable medium containing instructions that when executed cause at least one processor of an electronic device to:

• obtain multiple image frames of a scene using at least one camera of the electronic device;
• and
• process the multiple image frames of the scene to generate a higher-resolution image of the scene;
• wherein the instructions that when executed cause the at least one processor to process the multiple image frames of the scene comprise instructions that when executed cause the at least one processor to:
• generate an initial estimate of the scene based on the multiple image frames of the scene;
• in each of multiple iterations, (i) generate a current estimate of the scene based on the multiple image frames of the scene and a prior estimate of the scene and (ii) regularize the generated current estimate of the scene, the regularized current estimate of the scene from one iteration representing the prior estimate of the scene in a subsequent iteration;
• and
• continue the iterations until the estimates of the scene converge on the higher-resolution image of the scene;
• and
• wherein the instructions that when executed cause the at least one processor to generate the initial estimate of the scene comprise instructions that when executed cause the at least one processor to warp at least some of the multiple image frames to align the image frames.
