Is the resolution real or interpolated?
Real. The CCD size is listed as 810,000 pixels. This is larger than the 786,432 pixels needed for 1024×768 resolution. This means the brightness of each pixel is not interpolated. However, digital cameras under about $5000 interpolate the color. That is, each individual pixel of the CCD can only record one of red, green, or blue. To generate an R, G, and B value for each pixel, the missing value is interpolated (“guessed”) from nearby pixels. This interpolation can sometimes lead to color fringing near high-contrast edges. • Is the CCD “progressive scan”? Not on the D-320L. A progressive scan CCD reads (scans) the image data from top to bottom in one pass. Interlaced (the opposite of progressive) CCD units read an interlaced image in two passes, similar to the way a TV displays an image. • Batteries: • What are the best choices? Lithium for disposables or NiMH for rechargeables, probably. Note that lithium batteries are very expensive, around $9-$15 for a set of four, but also last a r
