Samsung patents multi-camera long exposure photo method

This patent describes a method for taking long exposure photos using a device with multiple cameras. One camera detects moving objects to trigger a second camera to capture frames at a different speed, which are then combined to create a final image with dramatic motion effects.

Why it mattersThis could improve the quality of creative photo modes on future phones by better handling moving subjects in long exposure shots.

In the filing’s own words

The present subject matter refers to a controlling method of an electronic apparatus for long exposure photography in a multi-camera device. The method includes receiving first image frames at a first frame rate from a first camera of the multi-camera device, detecting a presence of at least one moving object in each of the first image frames, based on the detection of the at least one moving object in each of the first image frames, utilizing a second camera for receiving second image frames at a second frame rate, performing a motion analysis on each of the first image frames for selection of one or more frames among the second image frames, based on the one or more frames being selected, identifying motion gaps in each of subsequent frames among the selected one or more frames, based on the motion gaps being identified, generating one or more in-place frames, and generating a motion dramatizer image based on the one or more in-place frames.

What exactly they claim (claim 1)

1. A method for controlling an electronic apparatus for performing long exposure photography in a multi-camera device, the method comprising: receiving first image frames at a first frame rate from a first camera of the multi-camera device; detecting a presence of at least one moving object in each of the first image frames; based on the detection of the at least one moving object in each of the first image frames, utilizing a second camera for receiving second image frames at a second frame rate; performing a motion analysis on each of the first image frames; selecting one or more frames among the second image frames based on the motion analysis; based on the one or more frames among the second image frames being selected, identifying motion gaps in each of subsequent frames among the selected one or more frames; based on the motion gaps being identified, generating one or more in-place frames; and generating a motion dramatizer image based on the one or more in-place frames.
