Due to the limitation of data bandwidth and other factors, it is difficult for the current technology to process and transmit massive images in real-time. With the requirement for fast response, the demand for real-time on-orbit image processing is increasing. In practice, nonuniformity correction is an important preprocessing step to improve the quality of surveillance images. This paper presents a new real-time on-orbit nonuniform background correction method, which only uses the local pixels of a single row output in real-time, breaking the dependence of the traditional algorithm on the whole image information. Combined with the FPGA pipeline design, when the local pixels of a single row are read out, the processing is completed, and no cache is required at all, which saves the resource overhead in hardware design. It achieves microsecond-level ultra-low latency. The experimental results show that under the influence of strong stray light and strong dark current, our real-time algorithm has a better image quality improvement effect compared with the traditional algorithm. It will greatly help the on-orbit real-time moving target recognition and tracking.<\/jats:p>","DOI":"10.1364\/oe.484781","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T10:00:50Z","timestamp":1685700050000},"page":"22204","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Real-time on-orbit image quality improvement for a wide-field imaging system with detector arrays"],"prefix":"10.1364","volume":"31","author":[{"given":"Dali","family":"Zhou","sequence":"first","affiliation":[{"name":"Changchun Institute of Optics"},{"name":"Changchun Institute of Optics, Fine Mechanics and Physics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaodong","family":"Wang","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics"},{"name":"Changchun Institute of Optics, Fine Mechanics and Physics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changxiang","family":"Yan","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haihong","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Tracking and Communication Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,6,16]]},"reference":[{"key":"oe-31-13-22204-R4","doi-asserted-by":"publisher","first-page":"178","DOI":"10.1016\/j.actaastro.2018.02.008","volume":"158","author":"Fernandez O","year":"2019","journal-title":"Acta Astronaut."},{"key":"oe-31-13-22204-R8","first-page":"74","volume":"3809","author":"Venkateswarlu","year":"1999","journal-title":"Proc.
