An energy-saving freshwater producing apparatus having a simple apparatus configuration. Seawater is heated by a heat-collecting device based on solar light, and the heated seawater is injected to one or more mist-forming structure formed as a rotor comprising a plurality of collision members formed to extend radially, to form a mist. Water vapor generated from the formed mist is introduced to a heat exchanger arranged in a side-by-side relation to the mist-forming structure in a horizontal direction through a demister, while being carried on an airstream by an airstream-forming device. Low-temperature seawater flows through the heat exchanger vertically from a lower side to an upper side thereof. The introduced water vapor is condensed into freshwater by cold energy of the seawater, and the freshwater is collected.

Upon setting of a halftone process of an initial setting, there is such a problem that graininess deteriorates due to an aging change or an environmental change. To solve this problem, an image processing apparatus executes a halftone process on a test image for tone correction and prints the processed test image; forms a tone correction table in accordance with read values from the printed test image; obtains graininess from a read value of a low density portion of a tone correction patch of the test image for the tone correction; discriminates whether the obtained graininess exceeds a predetermined reference level; and changes a setting of the halftone process so as to reduce the graininess when it is discriminated that the obtained graininess exceeds the predetermined reference level.
