Abstract: On the light-entering surface side of a base material 10, a coating layer 11 in which a high-refractive layer and a low-refractive layer are sequentially disposed alternately on one on the other is provided for blocking infrared radiation. One of the high-refractive layers is configured by an ITO film 11a so that the conductivity is increased on the surface of the coating layer.

Moreover, it is desirable if the total layer thickness is 140 nm or smaller for the refractive layers formed outside of the high-refractive layer made of the transparent conductive material.

Abstract: An image data processing method transforms a picture signal having a broad dynamic range to another picture signal having a narrow dynamic range. The picture signal having the narrow dynamic range is subjected to inverse transform to thereby output a recovered signal having the broad dynamic range. A difference between the original picture signal and the recovered signal, both having the broad dynamic range, is produced and then stored in a recording medium as difference data. A parameter for software processing to be executed for reproduction of the original picture signal later is also stored in the recording medium. In this way, the method can transform the original data with the broad dynamic range to the data of a standard file format with the narrow dynamic range, record the transformed data, and allow the original data to be recovered and effectively used later, as desired.
