Abstract: An imaging device includes: a solid-state imaging element that includes a plurality of pixels arranged in rows and columns and configured to be read out nondestructively; and an image processor that performs image processing on a current image using an analysis result of a suitable image. The suitable image is obtained from the solid-state imaging element when an amount of signal charge accumulated in the plurality of pixels is greater than or equal to a first threshold that is predetermined, and the current image is obtained from the solid-state imaging element after a first exposure corresponding to conditions of image capturing.

Abstract: A plate fin heat exchanger 1 includes a corrugated fin 3 and tube plates 2. An intermediate portion 33 of the corrugated fin between crest and trough portion 31 and 32 thereof has a plurality of protruding ribs 34 protruding beyond a surface of the corrugated fin and arranged in a first direction. Surfaces of the crest and trough portions being in contact with the tube plates are configured as contact surfaces 310, 320 with no protruding rib. Gently sloping portions 341 are provided between the protruding ribs and the contact surfaces of the crest and trough portions to gradually protrude from the surface of the corrugated fin with increasing distance from the contact surfaces, and are continuous with the protruding ribs.

Abstract: An imaging device includes a vertical transfer unit to sequentially transfer the charges generated by photoelectric conversion elements in a vertical direction with the transfer registers, during a vertical transfer period, a horizontal transfer unit to horizontally transfer the charges transferred by the vertical transfer unit, during a horizontal transfer period, and a controller to control the vertical transfer unit and the horizontal transfer unit. The controller controls the vertical transfer unit such that the number of transfer registers used to store the charges during the horizontal transfer period is larger than the number of transfer registers used to store the charges during the vertical transfer period.
