A rewritable thermal recording medium of this invention uses a recording material which reversibly changes between an equilibrium state and a quasi-equilibrium state different in color condition from the equilibrium state when a predetermined heat treatment is performed. This rewritable thermal recording medium includes a substrate and a recording layer formed on the substrate. The recording layer has a first region containing a first recording material which takes on lighter color in quasi-equilibrium than in equilibrium, and a second region containing a second recording material which takes on darker color in quasi-equilibrium than in equilibrium.

This invention provides a display control apparatus and control method, which allow the operator to easily identify the correspondence between the patch icons and their color difference values. To accomplish this, the display control method of this invention includes an icon displaying step of displaying a plurality of color difference values computed based on a first data group and second data group associated with spectral reflectance characteristics as a plurality of patch icons. The display control method includes a numeric value displaying step of displaying the color difference values represented by the patch icons in one of a first display format that displays, as numeric values, the color difference values within display regions of the patch icons, and a second display format that displays, as numeric values, the color difference values above display regions of a plurality of patch icons.

According to one embodiment, an image erasing apparatus decolors an image printed on a paper sheet using an ink containing at least a leuco dye, a developer, water, a water-soluble organic solvent, and a surfactant. The image erasing apparatus includes a heating unit, a feedback mechanism, and a control unit. The heating unit heats the paper sheet. The feedback mechanism supplies the paper sheet heated by the heating unit to the heating unit again. The control unit causes the feedback mechanism to supply the paper sheet to the heating unit a plurality of times so as to heat the paper sheet a plurality of times.
