Create image file from base64 data

I have base64 encoded image data. I am inserting the first few characters

string='data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD     /2wBDAAYEBQYFBAYGBQYHBwYIChAKCgkJChQODwwQFxQYGBcUFhYaHSUfGhsjHBYWICwgIyYnKSopG   R8tMC0oMCUoKSj/2wBDAQcHBwoIChMKChMoGhYaKCgoKCgoKCgoKCgoKCgoKCgo......'

I do next to him in ruby

decoded_string=Base64.decode64 string
output_file = Tempfile.new(['image','.jpeg'])
output_file.binmode
output_file.write image

After that, when I open 'image.jpeg' it gives error

Error interpreting JPEG image file (Not a JPEG file: starts with 0x75 0xab)

I have also tried

File.open('a.jpeg', 'wb') do|f|
   f.write decoded_string
end

In this case also I got the same error.

What am I doing wrong?
