However, the computation for the selected clipping points can be complex. In this paper, a novel algorithm is created to reduce the computation time of the state-of-the-art backlight power-saving algorithms. If the current frame is similar to the previous frame, it is unnecessary to execute the backlight power-saving algorithm for the optimal clipping points, and the derived clipping point from the previous frame can be used for the current frame automatically. In this paper, the motion vector information was used as the measurement of the similarity between adjacent frames, where the generation of the motion vector information requires no extra complexity since it is generated to reconstruct the decoded frame pixels before the display. The experiments showed that the proposed work can reduce the running time of the state-of-the-art methods by 25.21% to 64.22%, while the performances are maintained; the differences with the state-of-the-art methods in PSNR are only 0.02~1.91 dB, and those in power are only \u22120.001~0.008 W.<\/jats:p>","DOI":"10.3390\/s22197170","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T23:07:55Z","timestamp":1663888075000},"page":"7170","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Fast Control for Backlight Power-Saving Algorithm Using Motion Vectors from the Decoded Video Stream"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4079-9350","authenticated-orcid":false,"given":"Shih-Lun","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Chung Yuan Christian University, Chung Li City 32023, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsung-Yi","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Chung Yuan Christian University, Chung Li City 32023, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting-Lan","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7605-5214","authenticated-orcid":false,"given":"Chiung-An","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Ming Chi University of Technology, New Taipei City 24301, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Szu-Yin","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Ilan University, Yilan City 26047, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Liang","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Chung Yuan Christian University, Chung Li City 32023, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun-Hsien","family":"Tung","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Chung Yuan Christian University, Chung Li City 32023, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5158-0031","authenticated-orcid":false,"given":"Wei-Yuan","family":"Chiang","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center, Hsinchu City 30076, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,21]]},"reference":[{"doi-asserted-by":"crossref","unstructured":"Luis, \u00c1., Casares, P., Cuadrado-Gallego, J.J., and Patricio, M.A. (2021).
