Abstract
A method for displaying an image in a display device initially includes storing a plurality masks in a memory. A mask of the plurality of masks is selected randomly from the plurality of masks, when control information is received for a source image and used to change the orientation of the source image. Each mask controls the transfer of image lines in a different non-sequential order based on the control information.
Claims33
A method for displaying an image in a display device, comprising:
- selecting a mask;
- receiving control information for a source image;
- and
- changing an orientation of the source image using the mask,
- wherein the mask includes a plurality of constant values that control transfer of image lines in the source image to a display memory, the constant values arranged within the mask to cause the image lines to be transferred in a non-sequential order based on the control information, wherein each constant value controls transfer of a different one of the image lines in the source image to the display memory.
A system for displaying an image in a display device, comprising:
- a computer readable medium to store at least one mask;
- and
- a processor to change an orientation of a source image using the mask,
- wherein the mask includes a plurality of constant values that control transfer of image lines in the source image to a display memory, the constant values arranged within the mask to cause the image lines to be transferred in a non-sequential order based on control information, and wherein each constant value controls transfer of a different one of the image lines in the source image to the display memory.
A method for displaying an image in a display device, comprising:
- randomly selecting one of a plurality of the masks stored in a memory;
- receiving control information for a source image;
- and
- changing an orientation of the source image using the selected mask,
- wherein the mask is used to transfer image lines in the source image to a display memory in a non-sequential order based on the control information.
A computer-implemented method for transferring image information from a source memory to a display memory for presentation on a computer display, the image information comprising a plurality of image lines, each image line comprising a plurality of pixels, the transfer causing an image to be presented on the computer display conforming in orientation to one of a plurality of selectable orientations with respect to the computer display, the method comprising:
- determining one of the plurality of selectable orientations as the selected orientation;
- calculating a first increment parameter from the selected orientation;
- and
- selecting image lines in the source memory in a non-sequential order,
- for each image line:
- stepping seriatim through each pixel of the image line,
- for each pixel:
- transferring the value of that pixel to a display memory location indicated by a display memory pointer;
- updating the display memory pointer after each pixel transfer by adding the first increment parameter to the display memory pointer;
- and
- updating the display memory pointer after each image line by adding different increment parameters to the display memory pointer to transfer image lines in the source memory in said non-sequential order.
