图像处理设备和图像处理方法

Image processing apparatus, image processing method

Abstract

When determining an area in which color blur occurs from an image, there may be an area where color blur suppression is performed in an area even though color blur does not occur, and the area becomes more noticeable or less noticeable depending on a degree of gamma correction processing. To solve this problem, an image processing apparatus obtains a color blur suppression coefficient based on a gradient value obtained from the image, performs color blur suppression on the image data using the color blur suppression coefficient, and changes the color blur suppression coefficient corresponding to the gradient value according to brightness.
本发明提供了一种图像处理设备和图像处理方法。当判断图像上出现色模糊的区域时,可能存在即使色模糊未出现也在区域中进行色模糊抑制的区域,并且该区域根据伽马校正处理的程度变得更加显著或比较不显著。为了解决该问题,图像处理设备基于从图像获得的梯度值获得色模糊抑制系数,使用色模糊抑制系数来对图像数据进行色模糊抑制,并且根据亮度改变对应于梯度值的色模糊抑制系数。
