    • In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (SHA) and second focus detection pixels (SHB) are arranged while being distributed. The layouts of the first focus detection pixel (SHA) and the second focus detection pixel (SHB) are switched in pairs of focus detection pixels adjacent in the focus detection direction. Focus detection is performed using image waveforms obtained from the first focus detection pixel (SHA) and the second focus detection pixel (SHB) whose layouts are switched. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.
    • 在具有多个像素的图像传感器中,其对被摄体图像进行光电转换,包括第一焦点检测像素(SHA)和第二焦点检测像素(SHB)的多个焦点检测像素对被布置。 第一焦点检测像素(SHA)和第二焦点检测像素(SHB)的布局以焦点检测方向相邻的成对的焦点检测像素切换。 使用从布置被切换的第一焦点检测像素(SHA)和第二焦点检测像素(SHB)获得的图像波形执行焦点检测。 这减少了包括在对焦点检测像素对中的像素从对象的不同部分接收光通量时产生的焦点检测误差。
