Abstract
A method for displaying images in a display apparatus is provided herein. In the display apparatus, an image is displayed during each frame period of a plurality of contiguous frames. At first, original images are received, and each of the received original images is composed of M number of contiguous image rows. A predetermined amount of frame periods are grouped as a frame group. During each frame period, one of M number of image rows is selected as an initial image row. From the initial image row, N number of image rows are selected from the M number of image rows according to an image row selection rule to constitute an image for displaying. In each frame group, at least two different initial parameters are used within two frame periods in order to output different images.
Claims15
An image display method suitable for use in a display apparatus having a plurality of contiguous frame periods, and the display apparatus displaying an output image during each frame period, the image display method comprising:
- receiving an original image, wherein the original image comprises M number of contiguous image rows;
- grouping a predetermined number of the frame periods into a frame group;
- during each of the frame periods, selecting one of the M number of image rows as an initial image row, wherein in each of the frame groups at least two frame periods have a different initial parameter to correspond to different image contents, and the different initial parameter initializes the initial image row selected in the at least two frame periods as different rows of the original image;
- and
- during each of the frame periods, starting from the initial image row, selecting N number of image rows from the M number image rows according to an image selecting rule to form the output image, wherein each of the N number of image rows and each of the M number of image rows have a same number of image columns, and each pixel of the selected M number image rows is selected,
- wherein the image row selecting rule comprises a row selecting parameter, and the procedures of selecting the N number of image rows from the M number of image rows comprises:
- performing complex number adding calculation starting from the initial row using the row selecting parameter.
An image display method, suitable for use in a display apparatus comprising a display panel having a plurality of contiguous frame periods, and displaying an output image during each frame period, wherein the image display method comprising:
- receiving an original image, wherein the original image comprising M number of contiguous image rows;
- determining the display panel being in the 2qth or the (2q+1) th frame period, wherein q is larger than or equal to 0;
- when the display panel being in the 2qth frame period, adding a first initial parameter, selecting N number of image rows from the M number of image rows according to an image row selecting rule to form the output image, wherein the first initial parameter initializes an initial image row selected in the 2qth frame period as one of the M number of contiguous image rows of the original image;
- and
- when the display panel being in the (2q+1)th frame period, adding a second initial parameter, selecting N number of image rows from the M number of image rows according to the image row selecting rule to form the output image, wherein the second initial parameter initializes the initial image row selected in the (2q+1)th frame period as another one of the M number of contiguous image rows of the original image, wherein the first initial parameter is different from the second initial parameter, each of the N number of image rows and each of the M number of image rows have a same number of image columns, and each pixel of the selected M number image rows is selected,
- wherein the image row selecting rule comprises a row selecting parameter, and the procedure of selecting the N number of image rows from the M number of image rows comprises:
- performing complex number adding calculation starting from an initial row using the row selecting parameter.
A display apparatus, comprising:
- a receiving device, receiving an original image, wherein the original image comprises M number of contiguous image rows;
- a display panel, having a plurality of contiguous frame periods, and the display panel displaying an output image during each of the frame periods according to the original image;
- and
- a processing device, coupled to the receiving device to group a predetermined number of the frame periods into a frame group, and in each of the frame periods, selecting one of the M number of image rows as an initial image row, and starting from the initial image row, selecting N number of image rows from the M number of image rows according to an image selecting rule to form the output image;
- wherein in each of the frame group, at least two frame periods have a different initial parameter to correspond to different image contents, and the different initial parameter initializes the initial image row selected in the at least two frame periods as different rows of the original image;
- wherein each of the N number of image rows and each of the M number of image rows have a same number of image columns, and each pixel of the selected M number image rows is selected;
- and
- wherein in the image row selecting rule comprises a row selecting parameter, and starting from the initial row the processing device uses the row selecting parameter to perform complex number adding calculation.
