An image processing apparatus capable of suppressing image quality deterioration in an output image region determined based on reference pixel regions including image ends. The image processing apparatus includes a coefficient selection value generator that generates a coefficient selection value according to a filter coefficient changeover control signal supplied from a region information controller. In accordance with the coefficient selection value, filter coefficient sets are respectively output from coefficient tables. One of the filter coefficient sets is selected by a selector in accordance with a coefficient set selection value supplied from a coefficient set selection unit. Using filter coefficients that constitute the selected filter coefficient set, an image processor performs arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels.
An image processing apparatus having an image processing unit that performs arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels, comprising:
An image processing method including an image processing step of performing arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels, comprising:
A non-transitory computer-readable storage medium storing a program for causing an image processing apparatus to execute an image processing method including an image processing step of performing arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels, comprising:
A method of controlling an image processing apparatus having an image processing unit that performs arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels, the method comprising:
A non-transitory computer-readable storage medium storing a program for causing an image processing apparatus to execute a method of controlling an image processing apparatus having an image processing unit that performs arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels, the method comprising:
