  • Typical photo booths comprise a cabinet within which is provided a light source for illuminating the subject, an adjustable stool for seating the subject and a variety of curtain-like cloth backdrops, may be selected by the user (subject) and physically dragged into place.
  • These photo booths are typically used for taking passport photographs etc.
  • a flash is illuminated and a photograph is taken.
  • the process repeats itself until all required photos have been taken.
  • the developed photographs are delivered from a slot in the front of the machine.
  • This system incorporates so-called "chromakey” technology to superimpose an image of a subject over a computer generated backdrop.
  • chromakey technology to superimpose an image of a subject over a computer generated backdrop.
  • the particular chromakeying technology utilised by this machine is known from studio video production and will not be described here in detail.
  • the subject selects a backdrop from a variety of different possibilities and then seats himself in front ofa blue chromakey screen.
  • a camera provided within the body of the machine then captures an image of the subject and electronically superimposes that image over the backdrop in accordance with a matte generated by conventional chromakeying techniques.
  • the composite image of the subject and selected backdrop is then passed to a high quality printer that prints the composite image onto a card.
  • this system provides a single, continuous, light source to light the subject and to front-light the chromakey screen (in this case, a blue screen). If the light is set up to provide a good foreground image, it will tend to give a poor contrast between the subject image and the chromakey screen and so a reduction in the quality of the matte produced from that image. This reduction in contrast is due to the fact that the foreground and the background are both lit by similar quantities of light. Also, a large amount of the light tends to be reflected by the highly reflective chromakey screen and this again causes poor resolution between the image of the subject and the image of the background.
  • This invention provides a camera system for generating a composite image of a subject superimposed on a background image, the system comprising: (a) flash apparatus operable to flash illuminate the subject;
  • a matte generator for generating a matte from the non-flash-illuminated image
  • a chromakey image combiner for combining the background image with the flash-illuminated image in accordance with the matte to generate the composite image
  • the invention addresses the apparently conflicting requirements of suitably lighting the subject to capture an image for use in matte generation and as the foreground material, by the elegantly simple step of capturing two images under different lighting conditions.
  • One image is used for matte generation, and the other image is used as the foreground material.
  • the lighting arrangements can be varied between the two exposures, to provide a lighting arrangement particularly suitable for the respective use of each image.
  • flash lighting is selected for use in capturing the foreground material
  • non-flash illumination is selected for use in capturing the image for good discrimination between the subject and the chromakey screen in matte generation.
  • the flash apparatus has the advantage that a very rapid change in light level can be achieved. This is important because, for a good quality overlay, it is desirable to capture the two images very close together in time.

It is accepted that because the trial views are generated using mattes and foregrounds both derived from non-flash- illuminated images, their image quality will be lower.
  • the trial view images may well be of sufficient quality for planning and alignment of the scene.
  • the chromakey screen is backlit.
  • the screen can be distinguished by colour (e.g. a blue screen, although other colours may be used) , by luminance, or both.
