Image processing apparatus that specifies edge pixel in target image using minimum and maximum component values of pixel value in target image data
Image processing apparatus that specifies edge pixel in target image using minimum and maximum component values of pixel value in target image data
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.
