In a solid-state image pick-up device provided with a pixel for
distinguishing a light source type in a predetermined region of the
solid-state image pick-up device, a filter for transmitting a light
having at least a wavelength of 505 nm to 530 nm is provided as a filter
for distinguishing a light source type to be mounted on the pixel for
distinguishing a light source type. It is more suitable that the filter
for distinguishing a light source type should also transmit a light
having a wavelength of 640 nm or more. Consequently, a sunlight and a
fluorescent lamp can be distinguished from each other. In addition, it is
also possible to easily distinguish an ordinary type white fluorescent
lamp from the daylight color, day white color and bulb color of a
3-wavelength type fluorescent lamp.
