Abstract: The image processing apparatus performs region designation with respect to a displayed image. The image processing apparatus comprises a display unit configured to display an image constituted by a predetermined number of pixels, an input unit configured to receive a selection operation with respect to the image, a control unit, and a storage unit. The control unit generates a plurality of divided regions acquired by dividing the image in accordance with similarity calculated based on pixel values and pixel locations. Each time a divided region among the plurality of divided regions is selected according to the selection operation received by the input unit, the control unit stores identification information of the selected divided region in the storage unit in association with a selection order of selecting the divided region. The control unit displays the divided region corresponding to the stored identification information on the display unit in an identifiable manner.

Abstract: In the image processing apparatus, the control unit generates a plurality of divided regions by dividing the image in accordance with similarity calculated based on pixel values and pixel locations, and identifies a selection range constituted by one or more of the plurality of divided regions in accordance with the selection operation received by the input unit. The control unit performs erosion processing with respect to the selection range by reducing a number of pixels constituting the selection range, and performs dilation processing with respect to the selection range resulting from the erosion processing by increasing the number of pixels constituting the selection range resulting from the erosion processing. The number of pixels constituting the selection range resulting from the dilation processing is greater than the number of pixels constituting the selection range before the erosion processing.
