Method of notifying users regarding motion artifacts based on image analysis

One or more non-transitory computer readable media having digital code embedded therein for programming a processor to perform a method on a digital image acquisition device that comprises an image capture component for capturing digital images, a digital processing component and an auto-focus mechanism, wherein the method comprises:

• determining that a threshold camera motion blur has occurred in a captured digital image based on a real time analysis of the captured digital image and at least one further image each acquired with a same digital image acquisition device, such that said same digital image acquisition device captures each of said captured digital image and said at least one further image, within a temporal range that includes an exposure period of the captured digital image, and times proximately before and after said exposure period, and of approximately the same scene as that of the captured digital image, wherein the threshold camera motion blur comprises a qualitative non-zero distortion amount around one or more points or lines or both in the image compared to one or more relatively sharp matched points or lines, or both, in the at least one further image;
• comparing said captured digital image and said at least one further image, the at least one further image comprising a lower pixel resolution than the captured digital image;
• wherein the method further comprises matching pixel resolutions of the captured digital image and the at least one further image including at least one of up-sampling the at least one further image and sub-sampling the captured digital image;
• determining whether to notify the photographer, de-blur said captured digital image, or delay or initiate a subsequent image capture depending on whether the threshold camera motion blur has occurred in the captured digital image;
• notifying the photographer, de-blurring the captured digital image, or delaying or initiating said subsequent image capture, or determining to performing none of these operations, based on the determining depending on whether the threshold camera motion blur has occurred in the captured digital image;
• and
• de-blurred or not, storing, transmitting or displaying the captured digital image or a further processed version, or combinations thereof.

A method of notifying a photographer, de-blurring a digital image, or delaying or initiating a subsequent image capture, or combinations thereof, depending on determining whether a threshold camera motion blur has occurred in the digital image, wherein the method comprises:

• providing a digital image acquisition device that comprises an image capture component for capturing digital images and a digital processing component;
• determining that a threshold camera motion blur has occurred in a captured digital image based on a real time analysis of the captured digital image and at least one further image each acquired with a same digital image acquisition device, such that said same digital image acquisition device captures each of said captured digital image and said at least one further image, within a temporal range that includes an exposure period of the captured digital image, and times proximately before and after said exposure period, and of approximately the same scene as that of the captured digital image, wherein the threshold camera motion blur comprises a qualitative non-zero distortion amount around one or more points or lines or both in the image compared to one or more relatively sharp matched points or lines, or both, in the at least one further image;
• comparing said captured digital image and said at least one further image, the at least one further image comprising a lower pixel resolution than the captured digital image;
• matching pixel resolutions of the captured digital image and the at least one further image including at least one of up-sampling the at least one further image and sub-sampling the captured digital image;
• determining whether to notify the photographer, de-blur said captured digital image, or delay or initiate a subsequent image capture depending on whether the threshold camera motion blur has occurred in the captured digital image;
• notifying the photographer, de-blurring the captured digital image, or delaying or initiating said subsequent image capture, or determining to performing none of these operations, based on the determining depending on whether the threshold camera motion blur has occurred in the captured digital image;
• and
• de-blurred or not, storing, transmitting or displaying the captured digital image or a further processed version, or combinations thereof.
