A video display device includes performs a first Retinex process on an inputted video and a second Retinex process, which is different from the first Retinex process, on the inputted video. A video composing unit is configured to compose a video processed by the first Retinex processing unit and a video processed by the second Retinex processing unit in accordance with a feature of the inputted video, which is then displayed. In a process of composing the video processed by the first and second Retinex processing units, the video composing unit is configured to perform a process of converting a luminance level for each pixel so that more output luminance levels are assigned to a luminance band having a large frequency distribution to improve visibility of the video. A gain of the luminance level converting process is varied in accordance with an average pixel value level of the inputted video.

The present invention relates to a polymeric porous material characterized in that: the porous material has a bimodal pore size distribution attributable to macropores having a pore size of at least 50 nm and mesopores having a pore size of from 2 nm to less than 50 nm, the proportion of the specific surface area of the macropores to the specific surface area of all pores of the porous material is at least 10%, and the porous material is produced by (1) polymerizing a monomer in the presence of a polymerization initiator using as a porogen a solution obtained by dissolving a polymer having a weight-average molecular weight of at least 100,000 and a molecular weight distribution Mw/Mn of not more than 1.5 in a good solvent for the monomer, and (2) removing the porogen from the resultant product.
