摘要
An image processing apparatus performs: acquiring target image data representing a target image and including a plurality of pixel values each having a plurality of component values; generating first image data including a plurality of first pixel values each being related to a minimum value among the plurality of component values of corresponding one of the plurality of pixel values; specifying a plurality of first edge pixels using the first image data; generating second image data including a plurality of second pixel values each being related to a maximum value among the plurality of component values of corresponding one of the plurality of pixel values; specifying a plurality of second edge pixels using the second image data; and specifying a plurality of edge pixels using the plurality of first edge pixels and the plurality of second edge pixels, the plurality of edge pixels constituting an edge in the target image.
