IMAGE PROCESSING APPARATUS, METHOD, AND PROGRAM

Japanese Patent JP2013255179

A

To reduce the amount of data to generate.

An image processing apparatus comprises: a tone mapping transformation unit for reversible tone mapping transformation of image data represented with a floating point; a base layer generation unit which generates image data of a base layer by reducing the bit depth of the image data having undergone the tone mapping transformation by the tone mapping transformation unit; and an expansion layer generation unit for generating data of an expansion layer using the image data having undergone the tone mapping transformation by the tone mapping transformation unit and the image data of the base layer generated by the base layer generation unit. This technique can be applied to an image processing apparatus, for example.
