each of which can be independently adjusted. A new generation of Foveon X3 image sensor Quattro 贾宝玉传奇

Watch CP+2016 sigma SD Quattro series SD Quattro series camera on-site assessment using a sigma bayonet system that supports all Contemporary Sigma SIGMA GLOBAL VISION lens products, Art and Sports product line and for the lens of the camera lens, the corresponding optimization. The main difference between SDQ and SDQ H is a photosensitive element: SDQ using the APS-C frame approximately 29 million pixels X3 CMOS (1.5x SDQ H, equivalent coefficient) is used in APS-H frame approximately 44 million 800 thousand pixels X3 CMOS (equivalent coefficient 1.6x). The back LCD panel consists of 1 3 inch LCD screens with 1 million 620 thousand pixels and 1 monochrome information screens, and supports the peak focusing function. SIGMA SD Quattro SIGMA SD Quattro H two models are equipped with a new generation of Foveon X3 full color image sensor. SIGMA SD Quattro SIGMA SD Quattro H uses the lens without changing mirror in the design. The newly developed Super-Fine Detail (SFD) shooting mode can push the details of Foveon X3 sensor to the extreme. According to a shutter button while shooting 7 different exposure degree of RAW format pictures, processed in the SIGMA Photo Pro can be obtained after preserving rich details and has super wide latitude photos. And each RAW photo can be edited separately. SDQ and SDQ H introduced hybrid AF technology, which is expected to provide faster focusing speed than the DP series. The new SFD (Super Fine Detail) pattern can be used to synthesize 7 photos that surround exposure to 1 RAW files, each of which can be independently adjusted. A new generation of Foveon X3 image sensor Quattro, a single large area pixel 4 pixels respectively corresponding to the top middle and bottom, composed of three layers structure [1:1:4] new. Shading information is mainly composed of the upper record, capture color information at the same time, the middle and bottom of the respective color information extraction, through processing, the middle and bottom recorded pixel color information, and combined with the corresponding reduction to the top to capture the brightness information, so that each pixel can obtain the corresponding brightness and color information. By using the principle of the three layer structure of the vertical separation of color, the top record of the brightness information passed to the following two layers, in the realization of the pixels at the same time, the huge data processing to high speed. By carrying double "TRUE III" image processing engine, the new SD Quattro and SD Quattro H camera can process huge image data at high speed.

直击CP+2016 适马sd Quattro系列现场评   sd Quattro系列相机采用适马卡口系统,支持适马SIGMA GLOBAL VISION镜头产品中所有Contemporary, Art 以及Sports产品线的镜头,并且针对镜头对相机进行了相应的优化。   SDQ和SDQ H的主要区别在于感光元件:SDQ采用的是APS-C画幅约2900万像素X3型CMOS(等效系数1.5x),SDQ H采用的是APS-H画幅约4480万像素X3型CMOS(等效系数1.6x)。   背面液晶屏由1块3.0英寸约162万像素液晶屏和1块单色信息屏组成,并支持峰值对焦功能。   SIGMA sd Quattro SIGMA sd Quattro H两款机型均搭载新一代Foveon X3全色彩图像传感器。SIGMA sd Quattro SIGMA sd Quattro H在设计上采用了无反光镜可更换镜头的构造。   全新开发的Super-Fine Detail(SFD)拍摄模式能够将Foveon X3传感器的细节表现能力推向极致。按一次快门即可同时拍摄7张不同曝光程度的RAW格式照片,在SIGMA Photo Pro中进行处理后即可得到保留丰富细节并具有超广宽容度的照片。而每一张RAW格式照片又可单独进行编辑处理。   SDQ和SDQ H引入了混合AF技术,预期可以提供比DP系列更快的对焦速度。新增加的SFD(Super Fine Detail)模式可以将包围曝光7张的照片合成为1个RAW文件,同时其中每一张都可以做独立调整。   新一代Foveon X3图像传感器Quattro,顶层的4个像素分别对应中层和底层的单个大面积像素,组成了全新的三层式 [ 1:1:4] 构造。明暗信息主要由上层记录,同时捕捉色彩信息,中层和底层各自撷取色彩信息,通过运算处理,将中层和底层记录的色彩信息,还原并结合到顶层对应的像素所捕捉到的明暗信息,从而使每个像素都能获得相应的明暗和色彩信息。利用三层构造垂直分离色彩的原理,将顶层记录的明暗信息传递给下面两层,在实现了像素提升的同时,庞大的数据处理也得以高速化。   通过搭载双 “TRUE III”图像处理引擎,全新的sd Quattro 和sd Quattro H相机可以高速处理庞大的图像数据。相关的主题文章:
