A moving image encoding apparatus includes a motion vector detecting unit for executing from a wide and coarse search to a narrow and fine search in a plurality of steps and in a stepwise manner to detect a motion vector of each block in an input image. The motion vector detecting unit includes a block combining unit for generating a combination block, depending on a result of detection in a search step, a search use pixel extracting unit for extracting a search use pixel to be used in a next search step, from the combination block, and a second search combination block searching unit for performing the next search step with respect to the combination block using the search use pixel, and setting a detected motion vector of the combination block as the motion vector of each block of the combination block.
