Abstract
Abstract A television image processing system selectively connectable with a plurality of displays which are different in display format. The television image processing system includes a command outputting section for outputting a command representative of the display format of a display connected with the television image processing system; a sampling section for receiving an analog color TV signal and for outputting a digital image data for each of color components; and at least one data array changing section for receiving the image data and for forming an array of image data compatible with the display format specified by the command, the array of image data being supplied to the display connected with the television image processing system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
A television image processing system capable of being selectively connected to one of a plurality of displays which are different from one another in their type of display format, determined by the number of light emitting elements and the arrangement of colors used therein, the light emitting elements being grouped into a plurality of blocks in the horizontal scan direction, said image processing system being adapted to assign and output image data within one horizontal period to the respective blocks in said one display, and said television image processing system comprising: (a) a command output means for outputting a command representative of the display format in said connected display; (b) a sampling means for receiving an analog color TV signal and for outputting a digital image data for each of color components R, G and B; and (c) at least one data array changing means for receiving the image data from said sampling means to change the array of said image data to another array of data compatible with the display format specified by said command, the changed array of image data being then output to the respective blocks in said connected display.
Claim 2
Dependent Claim
69 words
A television image processing system as defined in claim 1, comprising a plurality of said data array changing means and wherein the number of said data array changing means is equal to the maximum number of blocks in said displays which are connectable with said television image processing system, whereby only the data array changing means equal in number to the blocks in any connected display can be actuated.
Claim 3
Dependent Claim
99 words
A television Image processing system as defined in claim 2 wherein each of said data array changing means includes data extracting means responsive to said command for extracting the image data within a period of extraction assigned to itself from all the image data output from said sampling means in one horizontal cycle; buffer memory means for temporally storing said extracted image data; and change executing means for receiving the image data read out from said buffer memory means and for changing the image data to an array of data compatible with the display format specified by said command.
Claim 4
Dependent Claim
100 words
A television image processing system as defined in claim 3 wherein said data extracting means includes address setting means responsive to said command for outputting a start address and an end address in said period of data extraction; address counter means for counting clocks from the beginning of one horizontal scan period; and comparator means for receiving said start and end addresses from said address setting means and for outputting a write signal enabling the image data to be written in said memory means if the output signal of said address counter means is between said start and end addresses.
Claim 5
Dependent Claim
73 words
A television image processing system as defined in claim 4 wherein the displays connectable with said television image processing system include a display actuatable in accordance with the first display format and a display actuatable in accordance with the second display format and wherein the number of light emitting elements in said second display format display is equal to four times the number of light emitting elements in said first display format display.
Claim 6
Dependent Claim
110 words
A television image processing system which comprises command output means for outputting a command representing a display format in a display to be connected with the television image processing system, sampling means for receiving an analogue colour TV signal and converting it into digital output image data for each of colour components R, G and B, and at least one data array changing means for receiving said image data from said sampling means and for changing the array of said image data to an array corresponding to the display format indicated by said command, the image data in the changed array being then output to said display for each block.
