摘要

PPROBLEM TO BE SOLVED: To provide non-liner transformation processing for suppressing data in a range in a minute level equivalent to noise components included in original data, and for preventing data in the other range from being affected. PSOLUTION: This non-linear transformation processor 10 for applying non-linear transformation processing having non-linear input and output characteristics to input data and for outputting the converted input data is provided with a processing range determination circuit 12; a level suppression circuit 14; and a level restoration circuit 16. The processing range determination circuit 12 determines the processing range (suppression range, restoration range) according to the size of the input data. The level suppression circuit 14 suppresses the input data within the suppression range equivalent to the range of noise components, and the level restoration circuit 16 converts the input data within a predetermined restoration range beyond the suppression range to gradually restore the input data from 0 to the original level of the input data according to the value of the input data. Also, the input data beyond the restoration range are outputted as they are. PCOPYRIGHT: (C)2008,JPO&INPIT

要解决的问题：提供非线性变换处理，以抑制与原始数据中包括的噪声分量等效的微小范围内的数据，并防止其他范围内的数据受到影响。解决方案：该非线性变换处理器10具有处理范围确定电路12，该非线性变换处理器10将具有非线性输入和输出特性的非线性变换处理应用于输入数据并输出转换后的输入数据。电平抑制电路14;处理范围确定电路12根据输入数据的大小确定处理范围（抑制范围，恢复范围）;以及电平恢复电路16。电平抑制电路14在等于噪声分量范围的抑制范围内抑制输入数据，并且电平恢复电路16在超出抑制范围的预定恢复范围内转换输入数据，以将输入数据从0逐渐恢复到噪声范围。输入数据的原始级别根据输入数据的值。同样，超出恢复范围的输入数据将按原样输出。
