Abstract: An evaluation image generation unit generates, based on an image, an evaluation image for haze correction. A transmission map generation unit generates, based on the evaluation image, a transmission map for the haze correction. A first correction unit applies the haze correction that is based on the transmission map to the evaluation image. A second correction unit applies the haze correction that is based on the transmission map to the image. A third correction unit corrects, based on an amount of change in the evaluation image before and after the application of the haze correction, brightness of the image to which the haze correction has already been applied.

Abstract: The heat source unit includes a refrigerant control valve and a controller. If the opening degree of the refrigerant control valve changes, the high pressure of the refrigeration cycle changes. The controller adjusts the opening degree of the refrigerant control valve in a stepwise manner. The amount of change by one step in the opening degree of the refrigerant control valve is the unit change amount. The physical quantity indicating the high pressure of the refrigeration cycle is the high pressure index. The controller changes the unit change amount employed when the high pressure index is higher than the reference value to a value lower than the unit change amount employed when the high pressure index is lower than the reference value.
