Claims (5)

1. Способ генерирования данных изображения с компенсированным перемещением из данных изображения двух полей чередующихся пикселей, содержащий шаг, состоящий из вычисления данных из данных изображения (В2, С2, D2) нечетного числа вертикально выравненных смежных пикселей, отличающийся следующими шагами: если данные перемещения меньше, чем первое пороговое значение, то оставляются эти данные (С2) изображения среднего пиксела нечетного числа вертикально выравненных смежных пикселей неизменными; если данные перемещения больше, чем второе пороговое значение, то заменяют эти данные (С2) изображения среднего пиксела на данные первого изображения, имеющие значение, которое находится между данными (В2, D2) изображения этих двух вертикально выравненных смежных пикселей; и если данные перемещения больше, чем первое пороговое значение, но меньше, чем второе пороговое значение, то заменяют эти данные (С2) среднего пиксела на данные второго изображения, имеющие значение, которое находится между неизменными данными изображения и данными первого изображения.1. A method of generating image data with compensated movement of two fields of alternating pixels from image data, comprising a step consisting of calculating data from image data (B 2 , C 2 , D 2 ) an odd number of vertically aligned adjacent pixels, characterized by the following steps: if the data moving less than the first threshold value, then these data (C 2 ) of the average pixel image of an odd number of vertically aligned adjacent pixels are left unchanged; if the movement data is greater than the second threshold value, then replace the middle pixel image data (C 2 ) with the first image data having a value that is between the image data (B 2 , D 2 ) of these two vertically aligned adjacent pixels; and if the movement data is greater than the first threshold value, but less than the second threshold value, then replace the middle pixel data (C 2 ) with the second image data having a value that is between the invariable image data and the first image data. 2. Способ по п.1, отличающийся тем, что данные первого изображения рассчитывают как среднее значение этих данных (В2, D2) двух вертикально выравненных смежных пикселей.2. The method according to claim 1, characterized in that the data of the first image is calculated as the average value of these data (B 2 , D 2 ) of two vertically aligned adjacent pixels. 3. Способ по п.1 или 2, отличающийся тем, что данные второго изображения рассчитывают как среднее значение неизменных данных изображения и данных первого изображения. 3. The method according to claim 1 or 2, characterized in that the second image data is calculated as the average value of the invariable image data and the first image data. 4. Способ по любому из пп.1 - 3, отличающийся тем, что данные перемещения рассчитывают как Н, поделенное Т при этом
Н = (H1 + 2Н2 + H3)
Т = Т1 + 2T2 + T3
и
Н1 = А1 - 2В1 + 2С1 - 2D1 + Е1
Н2 = А2 - 2В2 + 2С2 - 2D2 + Е2
H3 = A3 - 2B3 + 2C3 - 2D3 + E3
T1 = (A1 - 2C1 + E1) + (B1 - D1)
T2 = (A2 - 2C2 + E2) + (B2 - D2)
T3 = (A3 - 2C3 + E3) + (B3 - D3)
где A1, B1, C1, D1, E1, A2, B2, C2, D2, E2 и A3, B3, C3, D3, Е3 являются данными изображения пяти вертикально выравненных смежных пикселей соответственно, а С2 есть данные изображения среднего из этих пяти вертикально выравненных смежных пикселей.4. The method according to any one of claims 1 to 3, characterized in that the displacement data is calculated as H divided by T in this case
H = (H 1 + 2H 2 + H 3 )
T = T 1 + 2T 2 + T 3
and
H 1 = A 1 - 2B 1 + 2C 1 - 2D 1 + E 1
H 2 = A 2 - 2B 2 + 2C 2 - 2D 2 + E 2
H 3 = A 3 - 2B 3 + 2C 3 - 2D 3 + E 3
T 1 = (A 1 - 2C 1 + E 1 ) + (B 1 - D 1 )
T 2 = (A 2 - 2C 2 + E 2 ) + (B 2 - D 2 )
T 3 = (A 3 - 2C 3 + E 3 ) + (B 3 - D 3 )
where A 1 , B 1 , C 1 , D 1 , E 1 , A 2 , B 2 , C 2 , D 2 , E 2 and A 3 , B 3 , C 3 , D 3 , E 3 are image data of five vertically aligned adjacent pixels, respectively, and C 2 is image data of an average of these five vertically aligned adjacent pixels. 5. Способ по п.4, отличающийся тем, что первое пороговое значение равно 2, а второе пороговое значение равно 3. 5. The method according to claim 4, characterized in that the first threshold value is 2, and the second threshold value is 3.
