    • When pixels are simply skipped while keeping both an order of pixel information and a spatial positional relation the same as those in all-pixel readout, since a distance between pixels to be read out increases, the Nyquist frequency decreases and aliasing noise increases. A 5×5 pixel block is set as a unit pixel block and pieces of pixel information in first, third, and fifth columns of first, third, and fifth rows of a pixel arrangement are added and outputted as an output in an ath row and an ath column of the unit pixel block. Then, pieces of pixel information in sixth, eighth, and tenth columns of the first, the third, and the fifth rows of the pixel arrangement are added and outputted as an output in the ath row and a bth column of the unit pixel block. Subsequently, pieces of pixel information are added and outputted up to a last column or a column near the last column. Thereafter, pieces of pixel information in the first, the third, and the fifth columns of the sixth, the eighth, and the tenth rows of the pixel arrangement are added and outputted as an output in a bth row and the ath column of the unit pixel block. Subsequently, all arbitrary pixels are read out while repeating the same operation and skipping and adding pieces of pixel information.
    • 当像素被简单地跳过同时保持像素信息的顺序和空间位置关系与全像素读出中的顺序相同时,由于要读出的像素之间的距离增加,所以奈奎斯特频率降低并且混叠噪声增加。 将5×5像素块设置为单位像素块,并且将像素布置的第一,第三和第五行的第一,第三和第五列中的像素信息的像素信息相加并输出为运动行中的输出,并且运动 单位像素块的列。 然后,将像素配置的第一,第三和第五行的第六列,第八列和第五列中的像素信息的像素信息相加并输出为单位像素块的运动行和第b列中的输出。 随后,将像素信息添加并输出到最后一列或靠近最​​后一列的列。 此后,将像素配置的第六行,第八行和第十行的第一列,第三列和第五列中的像素信息相加并输出为第b行的输出和单元的运动列 像素块。 随后,在重复相同的操作并跳过和添加像素信息的同时读出所有任意像素。
