Apparatus and method for image mosiacking under low-light conditions

摘要

An apparatus, method and non-transitory computer readable medium for mosaicking a plurality of images captured in a low-light condition are disclosed. For example, the apparatus includes an image capturing module, a flash module, a computer-readable medium and a processor. The processor executes a plurality of instructions stored on the computer-readable medium. The operations include determining a spacing between each one of the plurality of images, capturing the plurality of images in accordance with the spacing, aligning the plurality of images that are captured and mosaicking the plurality of images that are aligned into a single image by, for each one of the plurality of images, replacing one or more pixels in the respective flash spot region using one or more pixels in a subsequent image that is in a same location as the respective flash spot region such that the information is recovered.

主权项

1. An apparatus for mosaicking a plurality of images captured in a low-light condition, comprising:
an image capturing module for capturing the plurality of images of an object; a flash module in communication with the image capturing module for activating a flash each time the image capturing module captures one of the plurality of images in the low-light condition; a computer-readable medium in communication with the image capturing module for storing the plurality of images that are captured, each one of the plurality of images having a flash spot region; and a processor in communication with the image capturing module, the flash module and the computer-readable medium for executing a plurality of instructions stored on the computer-readable medium, causing the processor to perform operations, the operations comprising:
determining a spacing between each one of the plurality of images to minimize a number of the plurality of images while capturing all portions of the object, and simultaneously recovering information that is lost due to a respective flash spot region in each one of the plurality of images captured in the low-light condition;capturing the plurality of images in accordance with the spacing;aligning the plurality of images that are captured; andmosaicking the plurality of images that are aligned into a single image by, for each one of the plurality of images, replacing one or more pixels in the respective flash spot region using one or more pixels in a subsequent image that is in a same location as the respective flash spot region such that the information is recovered.
