A modular camera and printer is disclosed. A camera module is provided having an image sensor for capturing an image in a RGB format. The camera module also has a central processing unit with program memory for storing program steps for execution by the central processing unit to operate the camera module, and an image storage memory for storing the captured image in the RGB format. An image processing unit of the camera module is in communication with the image storage memory and transforms image data in the image storage memory into a L*a*b* format. The camera module also has a serial bus for outputting transformed image data in the L*a*b* format. A printer module is provided also having a serial bus in communication with the serial bus of the camera module. The printer module receives the image data from the camera module in the L*a*b* format, converts the image data to a color space of the printer module, and then prints the image data on a printhead.
