Definitions
- the present invention relates to a television set.
- a television set which can provide a print or negative of any picture displayed on the screen of the set.
- Some systems for producing a print of a picture stored on such a camera or video camera are already available.
- a combination of a personal computer, a monitor, a video recorder and a thermal printer may be used to produce a print of an image stored on a video.
- a video typically consists of several thousand images, only a few of which will best capture a particular moment.
- a particular advantage of systems for producing a print of a picture recorded on video is that they allow the printing of images which were captured at exactly the right moment in time.
- a television set comprising: one or more picture data receiving terminals ; a screen; means for displaying the picture represented by said data on said screen; a print command means; and means for providing a print or negative of said picture; the arrangement being such that when a picture desired to be printed is displayed on said screen, said print command means is operated, whereupon said picture is recorded in said print or negative.
- Such a system provides the advantage that an image stored in a non-visible form can easily be converted into a visible form in which it can be immediately appreciated without the need for expensive or bulky apparatus.
- said print or negative providing means comprises ; an illumination source; and second means for displaying said picture; the arrangement being such that, in use, at the time that a picture desired to be printed is displayed on said screen, said print command means is operated, whereupon said picture is displayed on said second display means, the light from said illumination source projecting said picture displayed on said second display means onto a film, whereby the picture desired to be printed is recorded on said film.
- This arrangement has the advantage that the expense and bulkiness of a thermal printer is avoided.
- said television set further comprises: means for measuring the luminance component of said picture data; means for controlling the duration of the illumination provided by said illumination source responsive to the measurement of the luminance component; whereby the brightness of the print faithfully reproduces the luminance of said picture.
- said photographic film retaining means is arranged to retain an instant photographic film in use.
- Figure 1 is a schematic illustration of a television set with a print producing capability
- Figure 2 is a block diagram showing the different components of the television set and the flow of signals therebetween;
- Figure 3 is a schematic illustration of the optical system incorporated within the television set.
- Figure 1 shows a television set (10) which is arranged to provide a Polaroid (Registered Trade Mark) print of the picture present at the time a print command button (12) is pressed.
- the print command may also be initiated by use of a remote control.
- the television set is substantially identical to a conventional television and is therefore provided with a control panel (11) and a screen (30).
- the television (10) additionally has a hood portion (14) on its upper surface.
- the hood portion (14) is integrally moulded as part of the housing of the television (10) and extends rearwardly from a forward face flush with the front of the television.
- the forward face of the hood portion (14) is substantially rectangular being 15cm in length and 9 cm in height.
- the cross-section of the hood portion (14) is maintained as it extends at a slight downward angle through a distance of about 10cm towards the rear of the television.
- the hood portion (14) is provided at its forward end on its upper surface with a socket (not shown) for receiving a Polaroid (Registered Trade Mark) film cartridge.
- a mechanism for ejecting an exposed Polaroid (Registered Trade Mark) film is associated with the cartridge and serves to propel the exposed film in an upward direction so that it may be taken from the upper surface of the television by the user.
- FIG. 2 shows the components of the television set associated with the print facility and the flow of signals between those components.
- the TV set is provided with a number of inputs which accept picture data from conventional television aerials (20), satellite dishes (26), video cassette recorders (24), camcorders (26) and photographic cameras (not shown) .
- the signals from these devices are then processed in a conventional manner to provide an RGB signal.
- the RGB signal has four different signal components, namely red, green, blue and luminance components.
- the signal is applied to the cathode ray tube (28) of the television so as to form a picture on the screen (30) of the television.
- the television (10) is further provided with a picture freeze circuit (32) and a luminance level measuring circuit
- Both of these circuits are activated by a signal output from a print command circuit (36) .
- the print command circuit (36) is arranged to output a signal at the time the print button (12) is pressed or at the time a print command is received from the remote control unit.
- the picture freeze circuit (32) then stores the RGB signal representing the picture on the screen at the time of the activation signal from the print command circuit (36) .
- the picture freeze circuit (32) is connected to an LCD driver (42) and an LCD colour panel (44) such that the LCD colour panel (44) displays the picture which is stored in the picture freeze circuit.
- the luminance level measuring circuit (34) On receipt of the activation signal from the print command circuit the luminance level measuring circuit (34) provides a single pulse output, the duration of which is proportional to the level of the luminance signal in the picture which is desired to be printed.
- the pulse output by the luminance level circuit (34) is passed to a relay (38) which causes power to be applied to a light source (40) for the duration of the pulse.
- Figure 3 shows the optical system which is incorporated inside the hood (14) of the television set (10) .
- the principal axis of the optical system is arranged to lie along the central forward/rearward axis of the hood portion (14).
- the rearmost component of the optical system is a 5 incandescent light source (50).
- the light from this light source travels forwardly to a magenta filter (52) which ensures that the light which is passed therethrough has a similar frequency spectrum to that of daylight.
- the LCD colour panel (44) Immediately forward of the magenta filter (52) is the LCD colour panel (44) .
- This panel (44) has the shape of a square lamina whose sides are approximately 20mm in length. It will be remembered that the LCD panel (44) displays the colour picture stored by the picture freeze circuit (32) .
- Light passed forwardly through the filter and the LCD panel (44) then impinges on a lens (56) which focuses the image formed by the light passing through the LCD panel (44) onto a film (60) stored in the Polaroid (Registered Trade Mark) film cartridge.
- the focal length of the lens is 29mm and is provided with an aperture stop such that its F number is 2.
- a shutter (58) is provided to prevent light falling upon the film when the print facility is not in operation.
- the user of the system presses the print button (12) whereupon both the picture freeze circuit (32) and the luminance level measuring circuit (34) begin their operation.
- the picture freeze circuit (32) captures and stores the RGB signal describing the picture and provides this stored picture data to the LCD driver (42) and LCD panel (44).
- the LCD panel displays a colour image of the picture which was displayed on the television screen (30) at the time the print button (12) was pressed.
- the luminance level circuit (34) measures the luminance level of the picture which was displayed on the television screen (30) at the time the print button (12) was pressed. Once this measurement has been carried out, the shutter (58) is opened and the luminance level circuit (34) outputs a pulse whose duration is proportional to the luminance level of the picture desired to be printed. Power is then applied to the light source (50) during the duration of that pulse, which is typically around 1 second. Light from the light source is then filtered by the magenta filter (52) to provide light of a similar spectrum to daylight, the filtered light then passing through the colour LCD panel (44) and being focused by the lens (56) to form an image of the picture displayed on the LCD panel (44) on the Polaroid (Registered Trade Mark) film (60).
- the magenta filter (52) to provide light of a similar spectrum to daylight
- the filtered light then passing through the colour LCD panel (44) and being focused by the lens (56) to form an image of the picture displayed on the LCD panel (44) on the Polaroid (Registered
- the shutter (58) is closed and the ejection mechanism ejects the exposed Polaroid (Registered Trade Mark) film (60) upwardly from the hood portion (14) of the television set (10) so that the print can be collected by the user.
