Title
(ZH) 图像处理装置、图像处理方法以及程序
Abstract
(ZH) 提供了一种用于对图像中的局部高亮区域中出现的伪色进行伪色校正的装置和方法。在数据转换处理期间为了从RGBW阵列图像生成RGB阵列图像,检测伪色像素;计算低频带信号,该低频带信号与RGBW颜色中的每个颜色对应,并且取决于像素是否是伪色像素而不同;以及通过插值处理对RGBW阵列图像进行转换,以生成RGB阵列图像,所计算的低频带信号被应用于所述插值处理。在插值处理中,基于W低频带信号mW和RGB低频带信号mR、mG和mB在局部区域内具有比例关系的假设,使用低频带信号。在感兴趣像素是伪色像素的情况下,通过应用具有以下系数的低通滤波器来计算低频带信号:在该系数中靠近感兴趣像素的像素值的贡献相对小于更远的像素的像素值的贡献。
