Samsung, global shutter seviyesinde ak\u0131ll\u0131 telefon sens\u00f6r\u00fc geli\u015ftirmeyi ba\u015fard\u0131<\/b><\/p>\n

Bu teknolojiyi ak\u0131ll\u0131 telefonlara uyarlamak bug\u00fcne kadar zordu. \u00c7\u00fcnk\u00fc global shutter yap\u0131s\u0131 piksel boyutlar\u0131n\u0131 b\u00fcy\u00fctmeyi gerektiriyordu ve bu da \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011f\u00fc d\u00fc\u015f\u00fcr\u00fcyordu. Ancak Samsung, 12 megapiksellik<\/strong>, 1.5 mikrometre<\/strong> piksel aral\u0131\u011f\u0131na sahip bir rolling shutter lensine yeni bir piksel yap\u0131s\u0131 ekleyerek global shutter\u2019\u0131 ak\u0131ll\u0131 telefon formunda \u00e7al\u0131\u015f\u0131r hale getirmeyi ba\u015fard\u0131.<\/strong><\/p>\n

Normalde g\u00f6r\u00fcnt\u00fc sens\u00f6rleri, piksellerden gelen analog sinyalleri ADC\u2019de (Analog-Dijital D\u00f6n\u00fc\u015ft\u00fcr\u00fcc\u00fc) dijitale \u00e7evirir. Samsung ise ADC\u2019yi her pikselin i\u00e7ine entegre ederek piksel seviyesinde bir ADC mimarisi geli\u015ftirdi. Bu y\u00f6ntem piksel boyutunu b\u00fcy\u00fctt\u00fc\u011f\u00fc i\u00e7in, mevcut global shutter piksel boyutlar\u0131 yakla\u015f\u0131k 3 mikrometre <\/strong>seviyesinde. Samsung bu sorunu \u00e7\u00f6zmek i\u00e7in 1.5 mikrometrelik bir pikseli 2×2\u2019lik bir paket haline getirerek 3 mikrometrelik temel bir birim olu\u015fturdu.<\/p>\n

Bu d\u00f6rt piksel bir ADC\u2019yi payla\u015f\u0131yor, bu durumda 2×2\u2019lik b\u00f6l\u00fcm rolling shutter gibi s\u0131ral\u0131 \u00e7al\u0131\u015f\u0131yor, ancak geri kalan k\u0131s\u0131m global shutter i\u015flevi g\u00f6rebiliyor.<\/strong> Rolling shutter i\u015flemi k\u0131smen devam etti\u011fi i\u00e7in hafif bir bozulma olu\u015fuyor, bu y\u00fczden tam anlam\u0131yla bir global shutter de\u011fil.<\/p>\n

Samsung, optik ak\u0131\u015f bilgisini \u00e7\u0131kararak (nesne ya da kamera hareket etti\u011finde piksellerdeki parlakl\u0131k de\u011fi\u015fimi) hareket telafisini sa\u011flayan bir algoritma<\/strong> ekledi\u011fini s\u00f6yl\u00fcyor. B\u00f6ylece, \u00e7ok k\u00fc\u00e7\u00fck piksel boyutunda bile global shutter \u00f6zelliklerine sahip y\u00fcksek \u00e7\u00f6z\u00fcn\u00fcrl\u00fckl\u00fc bir sens\u00f6r elde etmeyi ba\u015fard\u0131klar\u0131n\u0131 belirtiyor.<\/p>\n

Samsung, bu \u00e7al\u0131\u015fmay\u0131 \u201cyar\u0131 iletken devrelerin olimpiyatlar\u0131\u201d olarak bilinen ISSCC 2026<\/strong> konferans\u0131nda sunmay\u0131 planl\u0131yor.\u00a0Bu y\u0131l\u0131n ba\u015flar\u0131nda Samsung, rolling shutter ve global shutter teknolojilerini birle\u015ftiren hibrit bir deklan\u015f\u00f6r konseptini de tan\u0131tm\u0131\u015ft\u0131.<\/p>\n

Bu arada Apple\u2019\u0131n da bu teknolojiye ciddi bi\u00e7imde ilgi g\u00f6sterdi\u011fi<\/strong>, global shutter sens\u00f6rleri iPhone\u2019lara entegre etmeye y\u00f6nelik patentler ald\u0131\u011f\u0131<\/strong> belirtiliyor. Apple ve Samsung\u2019un yeni nesil CMOS g\u00f6r\u00fcnt\u00fc sens\u00f6rleri \u00fczerinde birlikte \u00e7al\u0131\u015ft\u0131\u011f\u0131 da biliniyor.<\/p>\n\n
