JPEG images on a digital camera screen are usually in RGB format.

RGB JPEG is the default image format for photographs from digital cameras, cell phones and other mobile devices. RGB stands for red, green and blue. Screen images on computers, TVs, phones and cameras are comprised of these three colors in varying percentages to make up the full-color image or photograph on their display. If you intend to use a JPEG in a printed publication, such as a magazine, brochure or leaflet, you must convert the image to CMYK to be compatible with a commercial printing press. A commercial printer separates artwork into four color plates; cyan, magenta, yellow and black, or CMYK. The 'K' stands for 'keyline' and represents the black plate. Each separated color is printed over the next until a composite full-color document is achieved.
