A brightness level converting apparatus improves a contrast of an image represented by an image pickup signal output from a logarithmic conversion solid-state image pickup device, so as to obtain a natural image. For this purpose, the brightness level converting apparatus converts brightness levels in the image pickup signal output from the solid-state image pickup device which logarithmically converts an incident light quantity. In the brightness level converting apparatus, a brightness level converting section converts the brightness levels in the image pickup signal by using a brightness level converting function expressed by an S-shaped curve which indicates the relation between an input brightness level and an output brightness level and includes one inflexion point. Therefore, the contrast in a low brightness level range in the image pickup signal is reduced. At the same time, the contrast in a high brightness level range is reduced while appropriately keeping a gradation. With this, the contrast in an intermediate brightness level range in the image pickup signal is improved considerably. Therefore, the image represented by the image pickup signal whose brightness levels are converted becomes a further natural image.

Energy can be stored by directing fluid into an expandable receptacle that has a relatively heavy mass above it. The fluid fills the receptacle such that it expands and lifts up the heavy mass above it. At a time when energy is needed, the fluid can be allowed to flow out of the receptacle and through a turbine or hydraulic motor to generate power or electricity. Intermittent or unreliable sources of power can be used to fill the receptacle, or power from a power grid can be used to fill the receptacle at times that are off-peak. During peak-load times, the potential energy of the fluid in the receptacle can be converted to power. The receptacle can also be used to control water flows and can provide a source of power and potable water to a community.
