ISO15739新标准图卡/动态范围测试卡
动态范围测试卡用于测试色调响应,噪声,基本分辨率和色差还原。当与Stepchart模块使用时,可测试高密度范围。可用基材:半光,相纸,彩色LVT菲林。动态范围测试卡由Stepchart, Multicharts和Multitest模块支持。如果几个手动曝光可用,该测试卡可用于动态范围后期处理。Dmax =3.4足以用于像素尺寸比较小的照相手机和数码相机,但是该段单反通常具有更高的动态范围(并也手动曝光),这使得它们非常适合动态范围。This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and Multitest modules. Printed on 12x18 inch (305x457 mm) luster inkjet media.DetailsThis 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. Nominal patch densities are 0.1, 0.19, 0.3, 0.41, 0.53, 0.66, 0.81, 0.97, 1.17, 1.39, 1.66, and 2.0 for the 12 peripheral patches and 0.77, 0.90, 1.05 for the three central patches. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and ColorTest modules.The standard size has an active area of 11.4x17.1 inches (290x434 mm),printed on 12x18 inch (305x457 mm) luster (semigloss) inkjet media.1、厂家货源正品官方直售,公司生产周期短,出厂严格检测,货品品质保障,可通过国家计量院计量。2、关于尺码机身和包装尺寸为手动测量,由于测量工具和测量方法不同的因素,会存在1cm误差,但是不用影响运输和使用。3、关于颜色本店产品都是实拍图片,但是由于不同显示器分辨不同以及色温和对比度差异有所不同。4、关于客服可以通过阿里旺旺随时联系我们,如果旺旺回复不及时,也可以拨打我们的热线电话 顾工:13310057376(技术与销售一体,直达客户需求)5、关于售后我们将提供完整的售后服务,包括15天退货,正品保证,交期保障等等。6、关于发货本店根据货物及客户需求,尽可能选择快捷方便的物流运输服务,一般情况发顺丰快递!
