Sure Digi-View can capture images up to its maximum resolution when using a color splitter (read extra hardware expense) and an extremely stable digital freeze frame (read not a normal consumer unit – extra hardware expense.) Digi-View can also digitize images in Hi-Res at 4096 colors, with noticable color banding, sometimes very severe. I think digi-view is a good product, but I would hardly call it a high quality image processor. It does the job economically, and far better than similar systems on either the Amiga or other platforms, however. OK. IF YOU HAVE 2 MEGS OF RAM, you can link to Digi-Paint 3, a stand alone product at extra software expense. I have NEVER seen an advertisement for AREXX, and cannot get anyone to give me an understandable description of what it does and why it is a needed product. Perhaps you can write AREXX programs doing all kinds of miracles, if you happen to be a programmer and can find the product. Some versions of digi-view may save in larger file formats. I don't know. My version saves in 320×200 or 320×400 in HAM mode. It does have high resolution, which does a creditable job in grays, but lacks a sufficient number of colors to do the job with people, portraits, and nature scenes when using high res. color. (A limitation of Amiga hardware.) The fact remains that it is a slow scan digitizer, designed to reproduce static images with a video camera. Good images require a stable image for at least 30 to 60 seconds. Most video recorders cannot provide a stable enough image for that period of time to do a creditable job. I'd sure like to see hardware capable of displaying 16 million colors. By my count, a normal 320×400 interlaced screen has 128 THOUSAND pixels, while a high resolution 640×400 interlaced screen has 256 THOUSAND pixels. Even if each pixel were addressed separately with a discrete color, there is no way a normal Amiga screen can approach displaying 16 million colors. Even your high resolution overscan screen has only 354,640 pixels available. [ MORE ]
