Abstract
With the object of effecting color management of dynamic image data obtained under a variety of image capture conditions, when dynamic image data is recorded on a medium by means of a recording head, together with the dynamic image data, conversion characteristic data for the purpose of converting the dynamic image data to another color space is recorded on the medium.
Claims21
An image recording device comprising:
- first recording means that records dynamic image data on a medium;
- and
- second recording means that records on the medium, together with the dynamic image data, a plurality of conversion characteristic data for converting the dynamic image data to another color space,
- wherein said second recording means adds the plurality of conversion characteristic data to the dynamic image data as conversion sub-code information, and records the conversion sub-code information in a sub-code area of the medium, wherein said plurality of conversion characteristic data correspond to an image input condition, wherein, by assigning a single color space conversion characteristic to a group made up of a plurality of input characteristics, there is provided, for a number M of input characteristics (where M is an integer such that M is not less than 1), a number N of conversion characteristic data (where N is an integer such that N is not greater than M, nor less than 1).

An image recording method comprising the steps of:
- recording dynamic image data on a medium;
- recording on the medium, together with the dynamic image data, a plurality of conversion characteristic data for converting the dynamic image data to another color space,
- wherein the plurality of conversion characteristic data is added to the dynamic image data as conversion sub-code information, and the conversion sub-code information is recorded in a sub-code area of the medium, wherein said plurality of conversion characteristic data correspond to an image input condition, wherein, by assigning a single color space conversion characteristic to a group made up of a plurality of input characteristics, there is provided, for a number M of input characteristics (where M is an integer such that M is not less than 1), a number N of conversion characteristic data (where N is an integer such that N is not greater than M, nor less than 1).
A computer-readable medium storing a program for implementing an image recording method, the program comprising
- code for a first step in which dynamic image data is recorded on a medium;
- and
- code for a second step in which conversion characteristic data for converting the dynamic image data to another color space and the dynamic image data are recorded on the medium,
- wherein the plurality of conversion characteristic data is added to the dynamic image data as conversion sub-code information, and the conversion sub-code information is recorded in a sub-code area of the medium, wherein said plurality of conversion characteristic data correspond to an image input condition, wherein, by assigning a single color space conversion characteristic to a group made up of a plurality of input characteristics, there is provided, for a number M of input characteristics (where M is an integer such that M is not less than 1), a number N of conversion characteristic data (where N is an integer such that N is not greater than M, nor less than 1).
