Abstract
There is provided an image processing apparatus. An obtaining unit obtains an image, and first NR information defining noise reduction processing using a first noise reduction processing method which an external apparatus can apply to the image. A generating unit generates, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method. A noise reducing unit applies the noise reduction processing using the second noise reduction processing method to the image in accordance with the second NR information.
Claims16
An image processing apparatus comprising at least one processor and/or at least one circuit which functions as:
- an obtaining unit configured to obtain an image, and first NR information defining noise reduction processing using a first noise reduction processing method which an external apparatus can apply to the image;
- a generating unit configured to generate, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method;
- and
- a noise reducing unit configured to apply the noise reduction processing using the second noise reduction processing method to the image in accordance with the second NR information.
An image capturing apparatus comprising:
- an image sensor configured to capture an image;
- and
- at least one processor and/or at least one circuit which functions as:
- a first generating unit configured to generate first NR information defining noise reduction processing using a first noise reduction processing method;
- a second generating unit configured to generate, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method and which an external apparatus can apply to the image;
- a noise reducing unit configured to apply the noise reduction processing using the first noise reduction processing method to the image in accordance with the first NR information;
- and
- a recording unit configured to record the second NR information, and the image to which the noise reduction processing has not yet been applied by the noise reducing unit, in association with each other.
An image processing method executed by an image processing apparatus, comprising:
- obtaining an image, and first NR information defining noise reduction processing using a first noise reduction processing method which an external apparatus can apply to the image;
- generating, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method;
- and
- applying the noise reduction processing using the second noise reduction processing method to the image in accordance with the second NR information.
A control method executed by an image capturing apparatus comprising:
- capturing an image;
- generating first NR information defining noise reduction processing using a first noise reduction processing method;
- generating, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method and which an external apparatus can apply to the image;
- applying the noise reduction processing using the first noise reduction processing method to the image in accordance with the first NR information;
- and
- recording the second NR information, and the image to which the noise reduction processing has not yet been applied by the noise reducing unit, in association with each other.
A non-transitory computer-readable storage medium which stores a program for causing a computer to execute an image processing method comprising:
- obtaining an image, and first NR information defining noise reduction processing using a first noise reduction processing method which an external apparatus can apply to the image;
- generating, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method;
- and
- applying the noise reduction processing using the second noise reduction processing method to the image in accordance with the second NR information.
A non-transitory computer-readable storage medium which stores a program for causing a computer to execute a control method comprising:
- capturing an image;
- generating first NR information defining noise reduction processing using a first noise reduction processing method;
- generating, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method and which an external apparatus can apply to the image;
- applying the noise reduction processing using the first noise reduction processing method to the image in accordance with the first NR information;
- and
- recording the second NR information, and the image to which the noise reduction processing has not yet been applied by the noise reducing unit, in association with each other.
