Abstract
There is provided an image processing apparatus including a converting unit for converting a level range of an input image signal into a predetermined level range, and an outputting unit for outputting the converted image signal and first identification information which indicates the predetermined level range, the first identification information being correlated with the converted image signal.
Claims7
A method of processing an image signal with an image processing apparatus that includes a signal processing unit, the method comprising steps of:
- receiving, at the signal processing unit, an input image signal to which first identification information indicative of a level range of the input image signal is added;
- detecting the first identification information and determining the level range of the input image signal;
- converting the level range of the input image signal into a first predetermined level range in accordance with the first identification information and second identification information which corresponds to a level range of the image processing apparatus;
- adding the second identification information to the converted image signal so that the second identification information indicates the first predetermined level range of the converted image signal;
- and
- outputting the converted image signal and the second identification information added thereto,
- wherein the first and second identification information include information indicating at least one of the level range and a source identification flag which is used by the signal processing unit with respect to the input image signal.
