the evolution of color in tomatoes samples, during ripening under refrigeration or at room temperature, was studied by computer vision system (cvs). cvs consisted in a lighted stage, a ccd digital camera and a computer (laptop), all calibrated. the digital processing of images was performed with the adobe? photoshop? cs3 extended software, with which averaged images on l*, a* and b* coordinates were obtained. the proceeding tested, using cvs, allowed to study the variations of color during the ripening of tomatoes from images, by means of rectangular coordinates (l*, a*, b*). the ratio a*/b* and polar coordinates (c*, ho), showing statistically significant differences between samples determined (p<0,05).
