Claim One:
1. A device comprising: one or more processors; memory; a layout location assignment module configured to obtain plural image layout locations on a frame image, and allocate multiple images to the plural image layout locations; and an output module configured to output a composite image of the frame image and the multiple images, wherein the layout location assignment module determines one image having a highest image quality among the multiple images, and allocates the one image having the highest image quality to one image layout location having a highest priority among the plural image layout locations, and wherein the layout location assignment module uses respective color components R, G, and B of a target image to be processed, among the multiple images, to calculate a quasi-chroma/saturation X according to an equation given below: 
 X=|G+R− 2 R|, creates a histogram of the quasi-chroma/saturation X, determines a chroma/saturation at a specific pixel, which is 16% of the total number of pixels deviated inward from a maximum end in the histogram of the quasi-chroma/saturation X, and corresponds to a pixel having an actual maximum chroma/saturation, as a chroma/saturation index S, calculates an evaluation value Esatu of saturation according to an equation given below using the chroma/saturation index S: Esatu=25×(S 1/2 )/4, where the evaluation value Esatu is fixed to 100 when the chroma/saturation index S is greater than 256, and determines an image having a greatest calculated evaluation value Esatu of saturation as the image having the highest image quality.
