Since both the phase difference detection pixels and the image generation pixels are provided in one imaging element in the above-described related art, it is not necessary to individually provide two kinds of imaging elements, which are an imaging element for focus detection and an imaging element for captured images, in the imaging device.
由于在上述相关技术中，相位差检测像素和图像生成像素都设置在一个成像元件中，因此不必单独提供两种成像元件，它们是用于焦点检测的成像元件和成像元件。对于拍摄的图像，在成像设备中。

However, in the above-described related art, there is a case where a difference in characteristics of pixels occurs because pixels adjacent to the image generation pixels differ between image generation pixels adjacent to the phase difference detection pixels and image generation pixels not adjacent  to  the phase difference detection pixels.  It is considered that deterioration in image quality is brought about due to the difference in characteristics.
然而，在上述相关技术中，存在像素的特性差异的情况，因为与图像生成像素相邻的像素在相位差检测像素相邻的图像生成像素与不相邻的图像生成像素之间不同。T到相位差检测像素。认为图像质量的差异是图像质量下降的主要原因。

For example, since color filters are not included in the phase difference detection pixels, the amount of light leaked from the phase difference detection pixels to the image generation pixels is relatively large. For this reason, it is assumed that the image generation pixels adjacent to the phase difference detection pixels have a large amount of light leaked from the adjacent pixels, in comparison to the image generation pixels not adjacent to the phase difference detection pixels. For this reason, there is concern that an image generated by the imaging element including both the phase difference detection pixels and the image generation pixels looks poor.
例如，由于在相位差检测像素中不包括滤色器，所以从相位差检测像素泄漏到图像生成像素的光量相对较大。因此，与没有相邻的相位差检测像素的图像生成像素相比，假设相邻的相位差检测像素的图像生成像素具有从相邻像素泄漏的大量光。因此，存在由包括相位差检测像素和图像生成像素两者的成像元件生成的图像看起来很差的问题。

Therefore, an image correction process is necessary, which takes into account the difference between the characteristics of the image generation pixels adjacent to the phase difference detection pixels and the characteristics of the image generation pixels not adjacent to the phase difference detection pixels. In addition, the image correction process is necessary, which takes into account such a difference in characteristics for an image generated by an imaging element on which there are both image generation pixels and other different pixels (for example, white pixels).
因此，必须进行图像校正处理，该图像校正处理考虑到相邻于相位差检测像素的图像生成像素的特性与不邻近于相位差检测的图像生成像素的特性之间的差异。像素。此外，图像校正处理是必要的，它考虑到由图像生成像素和其他不同像素(例如，白色像素)同时存在的成像元件生成的图像的这种特性差异。

题目似乎可以改一下，SONY的条纹，与片上相位对焦点的关系。

自己顶一下。

根据提供的排列规律，做了个6024*4024像素的文件，把rivershaw 提到的那些行做了灰色填充。
