摘要： The in-vehicle camera includes an image sensor, a shutter, an image processing unit, and an exposure control unit. The image sensor includes multiple pixels to collect optical information. The shutter is a front curtain electronic type that includes a front curtain of an electronic type and a rear curtain of any type. An electronic controller starts collection of optical information in each pixel thereby opening the shutter. The image processing unit generates an image based on the optical information as collected. The exposure control unit controls the shutter to allow shutter times, during which the shutter is open for first and second image sensor areas obtained by dividing pixels P of the image sensor 15 into multiple areas, to be different from each other.

摘要： A surface treatment method for aluminum heat exchangers including (a) a step wherein a chemical conversion coating film is formed on the surface of an aluminum heat exchanger by subjecting the aluminum heat exchanger to chemical conversion using a chemical conversion agent; (b) a step wherein the aluminum heat exchanger, the surface of which has been provided with a chemical conversion coating film in step (a), is brought into contact with a hydrophilizing agent that contains a hydrophilic resin; and (c) a step wherein a hydrophilized coating film is formed on the surface of the aluminum heat exchanger by baking the aluminum heat exchanger, which has been subjected to a contact treatment in step (b). The chemical conversion agent used in step (a) contains zirconium and/or titanium in an amount of 5-5,000 ppm by mass in total, vanadium in an amount of 10-1,000 ppm by mass and a metal stabilizer in an amount of 5-5,000 ppm by mass. In addition, the chemical conversion agent used in step (a) has a pH of 2-6.
