You're trying to display an image in the YCbCr color space (that's what the I420 in your videoinput line means) with a function that is expecting RGB data.

If you do:

 vid = videoinput('winvideo', 1, 'I420_640x480');
 vid.ReturnedColorSpace = 'RGB';

then the toolbox will convert the data to RGB data when you call getsnapshot or getdata. If you actually want the YCbCr data you can omit changing the ReturnedColorSpace property and instead convert the data before displaying it:

 frame = getsnapshot(vid);
 imshow(ycbcr2rgb(frame));

MATLAB: How to save a sequence of images into a specific folder

ImageFolder ='C:\Users\person\Desktop\ Project\Matlab\Image Saving Test';
for i=1:5 % this loop will take 5 pictures and save them in the Matlab folder 
    img = snapshot(cam);
    file_name = sprintf('Image%d.png', i)% name Image with a sequence of number, ex Image1.png , Image2.png....
    fullFileName = fullfile(ImageFolder, file_name);
    imwrite(img,file_name,'png') %save the image as a Portable Graphics Format file(png)into the MatLab
    pause(1); % pause for one second
    imshow(img) % display the image for every second
    imgName = [ImageFolder,'\Image_',num2str(i),'.png'] ;
    imwrite(img,imgName) ; 
end
