A simple, cost-effective compression circuit which compress raw color data without interpolation. Control points common to all the colors in a line are generated each time one of the colors exceeds the color change threshold. The change in the other color is recorded at the same time even though it doesn't exceed the minimum change threshold.

1. A method for providing color image data from an image sensor to a host computer, comprising:providing at least two color values for a plurality of locations along a line of an image; generating control points along said line which are common to said two color values, said control points indicating a run length which is common to said two colors; compressing said color values to in dictate changes in both said color values between said control points, without in the interpolating said color values to provide color values at the same locations along said line; converting a digital representation of each of said color values and a run length since a last control point into equal sized data blocks; and providing each of said data blocks in sequence to a single compression block.
