For example, the image decoding apparatus 100 may determine square third coding units 1112a and 1112b by splitting the left second coding unit 1110a in a horizontal direction, and may determine square third coding units 1114a and 1114b by splitting the right second coding unit 1110b in a horizontal direction. Furthermore, the image decoding apparatus 100 may determine square third coding units 1116a, 1116b, 1116c, and 1116d by splitting both of the left and right second coding units 1110a and 1110b in a horizontal direction. In this case, coding units having the same shape as the four square second coding units 1130a, 1130b, 1130c, and 1130d split from the first coding unit 1100 may be determined.
As another example, the image decoding apparatus 100 may determine square third coding units 1122a and 1122b by splitting the upper second coding unit 1120a in a vertical direction, and may determine square third coding units 1124a and 1124b by splitting the lower second coding unit 1120b in a vertical direction. Furthermore, the image decoding apparatus 100 may determine square third coding units 1126a, 1126b, 1126c, and 1126d by splitting both of the upper and lower second coding units 1120a and 1120b in a vertical direction. In this case, coding units having the same shape as the four square second coding units 1130a, 1130b, 1130c, and 1130d split from the first coding unit 1100 may be determined.
