摘要
介绍了超高清电视摄像机技术标准,分析了超高清电视摄像机高分辨率、高帧频、高量化比特、宽色域、高动态范围的技术特点,结合拍摄的实际情况,提出了超高清电视摄像工作人员在拍摄模式、色彩空间、白平衡、伽玛曲线、聚焦方面进行合理选择与精确调整的技术要求。
This article introduces the technical standards of ultra-high-definition TV cameras,analyzes the technical characteristics such as high resolution,high frame rate,high quantization bit,wide color gamut and high dynamic range,of high-definition TV cameras. Combined with the actual situation of shooting,it proposes the technical requirements for reasonable selection,precise adjustment of the shooting mode,color space,white balance,gamma curve,and focus for ultra-high-definition TV camera workers.
