\u25cfOmniVision's OV50A<\/span><\/strong> \u00e9 um sensor de imagem de 50 megapixels (MP) com tamanho de pixel de 1,0 m\u00edcron, ganho de convers\u00e3o seletiva e formato \u00f3ptico de 1\/1,5 polegada, apresentando tecnologia de autofoco de detec\u00e7\u00e3o de fase qu\u00e1drupla (QPD) e remosaico no chip. O QPD permite o autofoco de detec\u00e7\u00e3o de fase 2\u00d72 (PDAF) em toda a matriz de imagem do sensor para cobertura de 100%. Ao contr\u00e1rio das tecnologias de microlente e PDAF semi-blindada que capturam apenas 3-6% de dados de detec\u00e7\u00e3o de fase, o QPD captura exclusivamente 100% de dados de detec\u00e7\u00e3o de fase para c\u00e1lculo de dist\u00e2ncia aprimorado, autofoco mais r\u00e1pido e melhor desempenho em pouca luz. Combinado com remosaico no chip para matrizes de filtros de cor QPD, ele permite imagens est\u00e1ticas premium e captura de v\u00eddeo 8K para c\u00e2meras principais amplas e ultra-amplas em smartphones principais e de \u00faltima gera\u00e7\u00e3o.<\/span><\/p>\n

\u25cfO sensor de imagem OV50A tem o melhor desempenho em baixa luminosidade da categoria por meio de uma combina\u00e7\u00e3o exclusiva de um grande tamanho de pixel de 1,0 m\u00edcron, baixo ru\u00eddo com ganho de convers\u00e3o seletivo, um modo de alto ganho de convers\u00e3o e um grande formato \u00f3ptico de 1\/1,5 polegada. Al\u00e9m disso, o sensor fornece excelente HDR por meio de temporiza\u00e7\u00e3o HDR escalonada de 2 e 3 exposi\u00e7\u00f5es, bem como ganho de convers\u00e3o seletivo para atingir o melhor equil\u00edbrio entre qualidade de imagem em baixa luminosidade e HDR. Esses recursos fornecem aos designers m\u00f3veis a m\u00e1xima flexibilidade para escolher o melhor m\u00e9todo HDR para \u00e1reas de contraste claras e escuras em qualquer cena.<\/span><\/p>\n

\u25cfO OV50A \u00e9 baseado na tecnologia de chip empilhado PureCel\u00ae Plus-s da OmniVision, integrando uma matriz de filtro de cor QPD no chip e hardware remosaic, proporcionando desempenho de foco autom\u00e1tico significativamente melhorado e sa\u00edda Bayer de 50 MP de alta qualidade ou v\u00eddeo 8K em tempo real. Isso tamb\u00e9m pode usar bloqueio pr\u00f3ximo a pixels para produzir imagens de 12,5 MP para v\u00eddeo 4K2K, com quatro vezes a sensibilidade, produzindo pr\u00e9-visualiza\u00e7\u00e3o de 2,0 m\u00edcrons e desempenho de v\u00eddeo. Em ambos os casos, o OV50A captura consistentemente imagens da mais alta qualidade com zoom de corte digital 2x em resolu\u00e7\u00e3o de 12,5 MP e troca r\u00e1pida de modo.<\/span><\/p>\n

\u25cfOs formatos de sa\u00edda incluem v\u00eddeo de 50 MP ou 8K a 30 quadros por segundo (fps) com foco autom\u00e1tico QPD, 12,5 MP a 60 fps com foco autom\u00e1tico QPD, v\u00eddeo 4K2K a 90 fps com foco autom\u00e1tico QPD, 1080p a 240 fps e 720p a 480 fps. Todas essas op\u00e7\u00f5es podem ser produzidas em at\u00e9 3,5 Gsps\/trio por meio da interface CPHY-MIPI do sensor.<\/span><\/p>\n

\u25cfOmniVision's OV50A is a 50-megapixel (MP) image sensor with 1.0-micron pixel size, selective conversion gain, and 1\/1.5-inch optical format, featuring quad phase detection (QPD) autofocus technology and on-chip remosaic. QPD enables 2×2 phase detection autofocus (PDAF) across the entire image array of the sensor for 100% coverage. Unlike microlens and semi-shielded PDAF technologies that only capture 3-6% of phase detection data, QPD uniquely captures 100% of phase detection data for improved distance calculation, faster autofocus, and better low-light performance. Combined with on-chip remosaic for QPD color filter arrays, it enables premium still images and 8K video capture for wide and ultra-wide main cameras on flagship and high-end smartphones. \u25cfThe OV50A image sensor has best-in-class low-light performance through a unique combination of a large 1.0-micron pixel size, low noise with selective conversion gain, a high conversion gain mode, and a large 1\/1.5-inch optical format. In addition, the sensor provides excellent HDR through 2- and 3-exposure staggered HDR timing, as well as selective conversion gain to achieve the best balance between low-light image quality and HDR. These features provide mobile designers with maximum flexibility to choose the best HDR method for light and dark contrast areas in any scene. \u25cfThe OV50A is based on OmniVision's PureCel\u00ae Plus-s stacked chip technology, integrating an on-chip QPD color filter array and hardware remosaic, providing significantly improved autofocus performance and high-quality, 50MP Bayer output or 8K real-time video. This can also use near-pixel blocking to output 12.5MP images for 4K2K video, with four times the sensitivity, producing 2.0-micron preview and video performance. In either case, the OV50A consistently captures the highest quality images with 2x digital crop zoom at 12.5MP resolution and fast mode switching. \u25cfOutput formats include 50MP or 8K video at 30 frames per second (fps) with QPD autofocus, 12.5MP at 60 fps with QPD autofocus, 4K2K video at 90 fps with QPD autofocus, 1080p at 240 fps, and 720p at 480 fps. All of these options can be output at up to 3.5 Gsps\/trio via the sensor\u2019s CPHY-MIPI interface. \u25cfProduct Features: \u25a0Automatic Black Level Calibration (ABLC) \u25a0Programmable Control: \u25b2Frame Rate \u25b2Mirror and Flip \u25b2Binning \u25b2Crop \u25b2Windowing \u25a0Support Dynamic DPC \u25a0Support Output Format: \u25b210-bit RGB Raw \u25a0Support Horizontal and Vertical Subsampling \u25a0Support Typical Image Size: \u25b28192 x 6144 mm \u25b24096 x 3072 mm \u25b24624 x 4320 mm \u25b21920 x 1080 mm \u25b21280 x 720 mm \u25a0Up to 4-lane MIPI D-PHY TX interface, up to 3.0 Gbps\/lane \u25a02\/3 trio C-PHY interface, up to 3.5 Gsps\/trio \u25a0Support Type 2 QPD PDAF \u25a0HDR Support: \u25b2Staggered HDR 2\/3 exposure time \u25a0Dual I\/O power supply (1.2V\/1.8V) \u25a0Three on-chip phase-locked loops (PLLs) \u25a0Programmable I\/O drive capability \u25a0Standard serial SCCB interface \u25a0Built-in temperature sensor \u25a01.008\u03bcm pixel<\/p>","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","footnotes":""},"categories":[665],"tags":[667,668],"class_list":["post-13228","post","type-post","status-publish","format-standard","hentry","category-50mp-camera-sensor","tag-ov50a","tag-ov50a40"],"_links":{"self":[{"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/posts\/13228","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/comments?post=13228"}],"version-history":[{"count":0,"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/posts\/13228\/revisions"}],"wp:attachment":[{"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/media?parent=13228"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/categories?post=13228"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/dgzx.hk\/pt\/wp-json\/wp\/v2\/tags?post=13228"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
