PROBLEM TO BE SOLVED: To provide a device for color or monochromatic scanning and for making digital image with large capacity and variable resolution by time-shifting a signal received from a transfer gate connected to one of a plurality of optical sensor elements to a signal received from a transfer gate connected to a different optical sensor element. SOLUTION: A tri-linear optical sensor array 40B provided with a plurality of optical sensor elements 46, 44 and 42 has three independent transfer gates B202, G204 and R206 for receiving blue, green and red transfer gate signals. Three time-shifted transfer gate signals TGB, TGG and TGR are applied to the transfer gates B202, G204 and R206 and the blue, green and red optical sensor elements 46, 44 and 42 are triggered so that they are scanned at a point where time is shifted in such a way that blue, green and red integrated scenes 80, 70 and 60 are combined to registered images.
