Good Direct Parallel Direct Parallel Legend Excellent Able to reproduce image at or beyond the resolution of the microscope. Very Good Matches the resolution of the microscope without image enhancement. Marginal Does not match the microscope image in one or more ways. A board-level addition to the computer that converts analog video images to digital images in real or delayed time. Direct Permits a digital image to be stored in a computer without a scanner or image processor.
Digital cameras use color wheels or color matrix CCDs to capture color information in the image.
All of the lower cost digital imaging cameras use this form of sensor. Color is provided by segregating the color information into a mosaic on the chip surface. This is accomplished by taking a group of four pixels and assigning a color frequency to each in a specific pattern. There are usually single red, single blue and two green pixels in the array. This array is replicated over the chip surface to create a color mosaic on to which the incoming color image is mapped.
