Abstract
[Object] To prevent an inappropriate processing parameter from being used in a case in which an image that may be expressed by various expression methods is handled. [Solution] Provided is an image processing device including: a control unit that decides a processing parameter for image processing performed on an image on the basis of at least one of a transfer function related to conversion between light and an image signal that is applied to the image or a color range that is applied to the image; and a processing unit that executes the image processing using the processing parameter that is decided by the control unit.
Claims18
An image processing device comprising:
- circuitry configured to:
- decide a processing parameter for image processing performed on an image based on at least one of (i) a transfer function related to conversion between light and an image signal that is applied to the image or (ii) a color range that is applied to the image;
- and
- execute the image processing using the decided processing parameter, the decided processing parameter representing a gain of a quantization step, the quantization step being adjusted strictly to a smaller value as the gain increases.
An image processing method comprising:
- deciding a processing parameter for image processing performed on an image based on at least one of (i) a transfer function related to conversion between light and an image signal that is applied to the image or (ii) a color range that is applied to the image;
- and
- executing the image processing using the decided processing parameter, the decided processing parameter representing a gain of a quantization step, the quantization step being adjusted strictly to a smaller value as the gain increases.
A non-transitory computer readable medium storing computer readable instructions thereon that, when executed by a processor of an image processing device, causes the processor to perform a method comprising:
- deciding a processing parameter for image processing performed on an image based on at least one of (i) a transfer function related to conversion between light and an image signal that is applied to the image or (ii) a color range that is applied to the image;
- and
- executing the image processing using the decided processing parameter, the decided processing parameter representing a gain of a quantization step, the quantization step being adjusted strictly to a smaller value as the gain increases.
