Abstract
Abstract A test pattern display apparatus and method thereof for adjusting the display parameters of a television picture, font data in the form of a test pattern stored in a font memory. The test pattern can be internally generated and displayed as needed, by a key input. The microcomputer repeatedly reads the font data of the selected test pattern, to form an entire test pattern, whenever accurate picture adjustments is desired.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A test pattern display apparatus for use in a television, said apparatus comprising: storage means for storing font data of a unit picture of a test pattern having a predetermined shape, said unit picture constituting portions of horizontal lines of a video frame and portions of vertical lines of the video frame; control means for repeatedly reading said stored font data of the unit picture and repeatedly outputting a drive signal corresponding to the read font data, thereby outputting data of one frame of said test pattern; drive means for converting said output drive signal into an image signal and outputting the converted image signal; and display means for displaying the converted image signal as said test pattern.
Claim 2
Dependent Claim
118 words
A test pattern display apparatus for use in a television, said apparatus comprising: storage means for storing font data of a unit picture of a test pattern having a predetermined shape, said unit picture constituting portions of horizontal lines of a video frame and portions of vertical lines of the video frame; control means for repeatedly reading said stored font data of the unit picture and repeatedly outputting a drive signal corresponding to the read font data, thereby outputting data of one frame of said test pattern; drive means for converting said output drive signal into an image signal and outputting the converted image signal; and display means for displaying the converted image signal as said test pattern.
Claim 3
Dependent Claim
35 words
A test pattern display apparatus according to claim 1, wherein said storage means stores said font data of the unit picture in order to form at least a crosshatching pattern and a color bar pattern.
Claim 4
Dependent Claim
119 words
A test pattern displaying method for displaying at least one type of test pattern for picture adjustment by storing font data of a unit picture for forming said at least one type of test pattern, said method comprising the steps of: selecting a test pattern type according to a key input; repeatedly reading the stored font data of the unit picture constituting portions of horizontal lines of a video frame and portions of vertical lines of the video frame according to said selected test pattern type thereby outputting data of one frame of the test pattern; forming the test pattern corresponding to the selected pattern type based upon the repeatedly read font data; and displaying the formed test pattern.
Claim 5
Dependent Claim
119 words
A test pattern displaying method for displaying at least one type of test pattern for picture adjustment by storing font data of a unit picture for forming said at least one type of test pattern, said method comprising the steps of: selecting a test pattern type according to a key input; repeatedly reading the stored font data of the unit picture constituting portions of horizontal lines of a video frame and portions of vertical lines of the video frame according to said selected test pattern type thereby outputting data of one frame of the test pattern; forming the test pattern corresponding to the selected pattern type based upon the repeatedly read font data; and displaying the formed test pattern.
Claim 6
Dependent Claim
25 words
A test pattern displaying method according to claim 3, wherein said test pattern formation step reads repeatedly the font data according to a crosshatching pattern.
Claim 7
Dependent Claim
25 words
A test pattern display method according to claim 3, wherein said test pattern forming step reads the font data according to a color bar pattern.
