Definitions
- This patent of invention refers to a TV set with coupled printer, which essentially consists of printing the image on the screen of a TV set, characterizing something new, practical, safe and highly functional.
- This TV set with coupled printer belongs to the technical sector of general electronic engineering.
- the object of this patent of invention is just a device enabling the coupling of a printer to TV set, as a simple and economical means for keeping a printed copy of a scene presented.
- Figure 1 conceptually shows the part related to the processing of the image of a TV set, which is formed by great blocks;
- Figure 2 shows an example of alternative, in order to perform the processing of the image of a TV set.
- the TV set with coupled printer which essentially consist of printing the image on the screen of a TV set is formed by the following great blocks:
- said great blocks 1, 2, 3, 4 and 5 are complemented with the following additional blocks, at least:
- processor 9 consisting of the classic functions of central processor, RAM and ROM memories, program, etc., which shall process the digitalized image stored in the memory and transform it in a bitmap suitable to be sent to a printer 13;
- Suitable electric interface 10 arranged between the processor 9 and the memory 7;
- Suitable electric interface 12 arranged between the processor 9 and a control circuit 14, which may be the remote control of the TV set itself, in order to receive the command that the user wishes to print the image which is being shown.
- the operation of the blocks described above is processed as follows:
- the signals demodulated by block 2 are applied to the video amplifiers 3, being shown to the user by the cathode-ray tube 4.
- Simultaneously, such signals are applied to the analog/digital converting block 6 and are stored in the memory 7, which works as a round queue, continually storing a con- venient number of pictures.
- the processor 9 When the user wishes to print a certain image, he/she manipulates the (remote) control 14 which, through interface 12, informs such decision to the processor 9, which then executes the routines of freezing the image acquirement driving the interface 10, converting the image to a bitmap proper to the printer 13 being used and driving the printing process, sending the processed data through the interface 11 to the printer 13.
- the processor 9 Upon the completion of the printing process, the processor 9 frees the memory 7 through the interface 10 in order to restart the acquirement of images.
