Kitaoka's Tomato is a color illusion in which a semitransparent blue-green field is placed on top of a red object (a tomato). The tomato appears red even though the pixels would appear green if viewed in isolation. We show that this phenomenon can be explained by a high-pass filter and by histogram equalization. The results suggest that this illusion does not require complex inferences about color constancy; rather, the tomato's is available in the physical stimulus at the appropriate spatial scale and dynamic range.
北冈番茄是一种颜色错觉，其中一个半透明的蓝绿色区域放置在红色物体（一个番茄）之上。尽管这些像素单独看时会呈现绿色，但番茄看起来却是红色的。我们表明，这种现象可以通过高通滤波器和直方图均衡化来解释。结果表明，这种错觉并不需要关于颜色恒常性的复杂推理；相反，番茄的颜色在适当的空间尺度和动态范围内的物理刺激中是可获取的。
