Abstract: A corrugated fin of a heat exchanger is formed such that fin sections are joined together one after another in a tube axial direction of a plurality of flat heat-transfer tubes. Louvers in the fin sections of the corrugated fin are divided into a first louver group formed further upstream in a direction of flow of air than a drain slit in the corrugated fin and a second louver group formed further downstream in the direction of flow of air than the drain slit. Plate portions of the first louver group and plate portions of the second louver group are inclined to a flat-plate portion in the fin sections and inclined in respective directions that are opposite to each other. The drain slit includes a plurality of drain slits provided in a plurality of respective rows between the first louver group and the second louver group.

Abstract: Disclosed is an image processor that reduces or eliminates the effects of a flash band regardless of performing a shutter operation or not. An imaging device includes a flash band detector configured to determine whether each image of the consecutive images shown by image signals output from an imager is a flash band image a part of which is affected by a flash, and a flash band compensator configured to, if a first image is determined as the flash band image, generate a third image which is supposed where the third image is fully affected by a flash by using a second image which is not determined as the flash band image, and output the third image instead of the first image.
