Image processing apparatus, image processing method, and program

An image processing method performed in an image processing apparatus, the method comprising:

• inputting a distance image having distance information or parallax information up to a subject, detecting an error signal included in the distance image, and outputting a synthesis coefficient according to an error degree of an image region unit;
• applying a low pass filter with respect to the distance image and generating a noise reduction distance image;
• and
• generating a corrected distance image using a synthesis process of the distance image and the noise reduction distance image,
• wherein in the generating of the corrected distance image a synthesis process in which a synthesis ratio of the distance image and the noise reduction image is set in the image region unit is performed according to a synthesis coefficient of an image region unit output in the inputting of the distance image, and the corrected distance image is generated.

At least one non-transitory computer-readable medium including a program which, when executed, causes an image processing apparatus to execute image processing comprising:

• inputting a distance image having distance information or parallax information up to a subject, detecting an error signal included in the distance image, and outputting a synthesis coefficient according to an error degree of an image region unit;
• applying a low pass filter with respect to the distance image and generating a noise reduction distance image;
• and
• generating a corrected distance image using a synthesis process of the distance image and the noise reduction distance image,
• wherein, in the generating of corrected distance image a synthesis process in which a synthesis ratio of the distance image and the noise reduction image is set in the image region unit is performed according to a synthesis coefficient of an image region unit output in the inputting of the distance image, and the corrected distance image is generated.
