An image processing apparatus sets an image reference position in an input image, calculates a distribution of weights from the image reference position, sets a starting position in the input image, and partitions the input image into areas by working outward from the starting position, using the distribution of weights to calculate thresholds for adding picture elements to existing areas. The distribution of weights may, for example, allow picture elements distant from the image reference position to be added to a background area more easily than picture elements closer to the image reference position. In addition, multiple starting positions may be set. These provisions enable the background to be identified as a single area without requiring user input of an outline around each non-background area.
