Claim Text:
1. A method for determining a rectangular moving image region displayed in part of a display region, the display region having pixels arranged in row and column directions therein, the method comprising: a moving unit block judgment step of dividing the display region into unit blocks each including a predetermined number of pixels and judging whether each unit block is a moving unit block having a motion; a moving column block determination step of defining, as a column block, a set of unit blocks included in a column of the unit blocks, the column including one of the uppermost unit blocks and, if one column block includes at least one moving unit block, determining the column block as a moving column block; a moving row block determination step of defining, as a row block, a set of unit blocks included in a row of the unit blocks, the row including one of the leftmost unit blocks and, if one row block includes at least one moving unit block, determining the row block as a moving row block; a first rectangular moving image region determination step of determining, as a rectangular moving image region, a rectangular region specified by unit blocks included in both the moving row block and the moving column block; and a second rectangular moving image region determination step of determining, as a boundary of the rectangular moving image region, a region defined by edges in peripheral unit blocks, the peripheral unit blocks forming peripheral four sides of the rectangular moving image region, on the basis of pixels in the peripheral unit blocks, of the unit blocks included in the rectangular moving image region.
