Processor, image processing device including the same, and control method of image processing device

A control method of an image processing device, the method comprising:

• first detecting, by processing circuitry, a first bad pixel pattern based on first image data;
• correcting, by the processing circuitry, the first bad pixel pattern based on a plurality of first values of a plurality of first peripheral pixels in response to the first detecting to obtain a first correction result, the plurality of first peripheral pixels being peripheral to the first bad pixel pattern;
• second detecting, by the processing circuitry, the first bad pixel pattern and a second bad pixel pattern based on the first image data, the second bad pixel pattern being adjacent to the first bad pixel pattern;
• correcting, by the processing circuitry, the second bad pixel pattern based on a plurality of second values of a plurality of second peripheral pixels to obtain a second correction result, the plurality of second peripheral pixels being peripheral to the second bad pixel pattern;
• correcting, by the processing circuitry, the first bad pixel pattern by using the first correction result stored in a buffer in response to the second detecting;
• generating, by the processing circuitry, first correction image data associated with a pattern, the pattern comprising the first bad pixel pattern or the second bad pixel pattern;
• and
• storing, by the processing circuitry, the first correction image data in the buffer.

A processor for an image processing device, the processor comprising:

• an image determining device configured to,
• first detect a first bad pixel pattern based on first image data, and
• second detect the first bad pixel pattern and a second bad pixel pattern based on the first image data, the second bad pixel pattern being adjacent to the first bad pixel pattern;
• and
• an image correcting device configured to,
• correct the first bad pixel pattern based on a plurality of first values of a plurality of first peripheral pixels in response to the first detection to obtain a first correction result, the plurality of first peripheral pixels being peripheral to the first bad pixel pattern,
• correct the second bad pixel pattern based on a plurality of second values of a plurality of second peripheral pixels to obtain a second correction result, the plurality of second peripheral pixels being peripheral to the second bad pixel pattern,
• correct the first bad pixel pattern by using the first correction result stored in an external buffer in response to the second detection,
• generate first correction image data associated with a pattern, the pattern comprising the first bad pixel pattern or the second bad pixel pattern, and
• store the first correction image data in the external buffer.
