The influence of the illuminance and spectral composition of monochromatic surround fields on spatially induced blackness was investigated. The amount of induced blackness in a white 50' central field was measured as a function of the illuminance of monochromatic 64'-120' surround fields with a color-naming method. The function relating induced blackness to log surround illuminance was described by either the logistic function or the Weibull function. Action spectra for blackness were determined from those functions and were also measured directly with the method of adjustment. These action spectra indicated that blackness induction was determined only by the illuminance of the surround, regardless of the blackness level at the criteria and the wavelength of the surround. It was concluded that there is no chromatic contribution from the chromatic surround to blackness induction.
研究了单色环绕场的照度和光谱组成对空间诱导黑度的影响。采用颜色命名法，测量了白色50′中心场中诱导黑度的量，该量是单色64′ - 120′环绕场照度的函数。诱导黑度与对数环绕照度之间的函数关系可用逻辑函数或威布尔函数来描述。根据这些函数确定了黑度的作用光谱，并且还通过调整法直接进行了测量。这些作用光谱表明，黑度诱导仅由环绕场的照度决定，而与标准处的黑度水平和环绕场的波长无关。得出的结论是，彩色环绕场对黑度诱导没有色度贡献。
