Fig. 12

High-resolution views of Venus at 283, 365 and 2.02 µm (~ 6 km per pixel) from the Akatsuki UVI and IR2 cameras on May 6, 2016, are shown in the upper row. A color composite view of these images is shown in the lower row and is created from 2.02-µm (red), 365-nm (green) and 283-nm (blue) filter images. The oval-shaped bright spot seen in the 283-nm image is an artifact of the 283-nm filter. The quadrant boundaries of the CCD detector of the 2.02-µm camera can be seen in the image shown (top row, right column) due to unmatched gains of the readout amplifiers. Contrasts are seen on scales of about 100 km at 283 and 365 nm, and perhaps on a slightly larger scale at 2.02 µm; however, this may be due to the lower level of contrasts and the dynamic range of the data
