Abstract
Abstract A sub image display control system is composed of two sub image display control portions that are a display region control portion and a display timing control portion and a display output portion. A sub image data packet is composed of three types of data that are a sub image header, sub image display data, and sub image control data. In this structure, display spatial loss and display temporal loss can be remarkably reduced and sub images with wide applicability can be accomplished.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
105 words
A method for forming a sub image data packet including data of a sub image superimposed on a main image, the sub image data packet comprising: a sub image data portion for storing sub image data for displaying sub image information; a header portion for storing sub image header data for assigning at least a display position, a display size, and a display color of the sub image data; and a control data portion for storing control data for changing the display position, the display size, and the display color of the sub image data assigned by the sub image header data, pixel by pixel.
Claim 2
Dependent Claim
31 words
The method as set forth in claim 1, wherein said header portion includes information that represents whether data is present in said sub image data portion and said control data portion.
Claim 3
Dependent Claim
52 words
The method as set forth in claim 1, wherein data of said control data portion included in the sub image data packet is used as control data for said sub image data portion that is displayed when data is absent in said sub image data portion of the sub image data packet.
Claim 4
Dependent Claim
58 words
The method as set forth in claim 1, wherein the display position, the display size, and the display color are not controlled for data in said sub image data portion of the sub image data packet, but displayed corresponding to predetermined default values when data is absent in said control data portion of the sub image data packet.
Claim 5
Dependent Claim
49 words
The method as set forth in claim 1, wherein it is determined that the sub image data packet is in a display clear mode and data of said sub image data portion is cleared when data is absent in said sub image data portion and said control data portion.
Claim 6
Dependent Claim
120 words
The method as set forth in claim 1, wherein said header portion includes at least: sub image display position/size assigning data for assigning a display position and a display size of the sub image superimposed on the main image corresponding to the type of the main image; display color assigning data for assigning a display color of the sub image; compensating execution assigning data for assigning emphasis of contour of the sub image and so forth; sub image contrast assigning data for assigning a mixing ratio of the sub image and the main image; and sub image display start timing assigning data for assigning from what display unit of the main image the display of the sub image is started.
Claim 7
Dependent Claim
31 words
The method as set forth in claim 1, wherein the type of data of said sub image data portion includes information that represents data corresponding to field/frame of the main image.
Claim 8
Dependent Claim
40 words
The method as set forth in claim 1, wherein said control data portion includes: control data corresponding to the display unit of the main image; and sub image control data header for assigning the start position of the control data.
Claim 9
Independent Claim
228 words
A method for generating a sub image corresponding to a sub image data packet including data for the sub image superimposed on a main image, the sub image data packet comprising: a sub image data portion for storing sub image data for displaying sub image information; a header portion for storing sub image header data for assigning at least a display position, a display size, and a display color of the sub image data; and a control data portion including control data and a sub image control data header, the control data being adapted for changing the display position, the display size, and the display color of the sub image data assigned by the sub image header data, pixel by pixel, the sub image control data being adapted for assigning the start position of the control data, wherein a data format of said control data portion is assigned by a change start line number, the number of continuous lines, and the number of pixel change points on each line of a region of the sub image, a pixel number at which a change starts on each change line, a color of the sub image display data after an assigned pixel, a color of a contoured pixel, and a mixing ratio between the main image and the sub image being assigned repeatedly for the number of change lines assigned.
Claim 10
Dependent Claim
39 words
The method as set forth in claim 9, wherein the end of continuation of the change line is determined by assigning predetermined code to a line number, the number of continuous lines, and the number of pixel change points.
Claim 11
Dependent Claim
104 words
A recording medium for recording a sub image data packet of sub image information superimposed on a main image, the sub image data packet comprising: a sub image data portion for storing sub image data for displaying sub image information; a header portion for storing sub image header data for assigning at least a display position, a display size, and a display color of the sub image data; and a control data portion for storing control data for changing the display position, the display size, and the display color of the sub image data assigned by the sub image header data, pixel by pixel.
Claim 12
Dependent Claim

Claim 13
Dependent Claim
53 words
The recording medium as set forth in claim 11, wherein data of said control data portion included in the sub image data packet is used as control data for said sub image data portion that is displayed when data is absent in said sub image data portion of the sub image data packet.
Claim 14
Dependent Claim
59 words
The recording medium as set forth in claim 11, wherein the display position, the display size, and the display color are not controlled for data in said sub image data portion of the sub image data packet, but displayed corresponding to predetermined default values when data is absent in said control data portion of the sub image data packet.
Claim 15
Dependent Claim
50 words
The recording medium as set forth in claim 11, wherein it is determined that the sub image data packet is in a display clear mode and data of said sub image data portion is cleared when data is absent in said sub image data portion and said control data portion.
Claim 16
Dependent Claim
121 words
The recording medium as set forth in claim 11, wherein said header portion includes at least: sub image display position/size assigning data for assigning a display position and a display size of the sub image superimposed on the main image corresponding to the type of the main image; display color assigning data for assigning a display color of the sub image; compensating execution assigning data for assigning emphasis of contour of the sub image and so forth; sub image contrast assigning data for assigning a mixing ratio of the sub image and the main image; and sub image display start timing assigning data for assigning from what display unit of the main image the display of the sub image is started.
