Panoramic camera and its image pickup method

The invention discloses a kind of panoramic camera and its image pickup method, panoramic camera of the invention includes：N number of sub- camera；Synchronization control module；Splice correction module, for caching continuous m row pixel values in shooting image in the way of sliding window, and according to checking list set in advance and the m row pixel values of the caching, complete the correction to the pixel value, and it is sequentially output every a line pixel value after correction, wherein, m is more than image maximum distortion line number+2 set in advance, and m is less than total line number of the shooting image；Splice Fusion Module, for the intersection of the shooting image according to each sub- camera, the shooting image of sync pulse jamming is spliced into a stitching image under synchronization control module control by each sub- camera；And transport module.The panoramic camera treatment effeciency of the present invention more preferably, handles better quality, and be more beneficial for system design miniaturization.
