An arrangement is described for performing real-time mixing of two digital color images stored in compressed RGB format. Fig. 1 is a block diagram of an image color mixing system capable of mixing two color images. Image pels a and b are shown as inputs to the system. These two inputs are the two different images to be mixed which are represented in an RBG compressed form described later. Block 1 in Fig. 1 is composed of three decompression circuits. Each decompression circuit decompresses one of the three RBG digital values for the incoming compressed image pel a. Block 2 decompresses the second image (pel b). The outputs of Blocks 1 and 2 drive Block 3. Block 3 consists of 3 identical mixing circuits which are detailed in Fig. 2.
