Abstract

Systems, devices, and methods for driving projectors are described. The actual area projected over by a laser projector for a given pixel may not exactly match a desired projection area for the pixel, especially at edge regions of an image. In the present systems, devices, and methods, projection data is provided for at least one image to be projected by a laser projector. The projection data can include sets of alternative data sections at edge regions of the at least one image, effectively increasing resolution for the edge regions of the image. Depending on a projection pattern being used by a laser projector at a given time, select alternative data sections can be projected which closely match the actual area covered by the projection pattern, improving image quality.

Claims20

Dependent claims

A method of processing projection data by a system including at least one processor communicatively coupled to at least one non-transitory processor-readable storage medium, the method comprising:

for a first row of an image raster representing an image to be projected:
for a first portion of the first row:
providing, by the at least one processor, a first set of at least two data sections, the at least two data sections in the first set being different representations of the first portion of the first row;
storing, by the non-transitory processor-readable storage medium, the first set of at least two data sections as a first portion of the projection data;
for a second portion of the first row:
providing, by the at least one processor, a second set of at least one data section, the at least one data section of the second set representing the second portion of the first row;
and
storing, by the non-transitory processor-readable storage medium, the second set of at least one data section as a second portion of the projection data;
and
for a third portion of the first row:
providing, by the at least one processor, a third set of at least two data sections, the at least two data sections of the third set being different representations of the third portion of the first row;
and
storing, by the non-transitory processor-readable storage medium, the third set of at least two data sections as a third portion of the projection data.

A method of controlling a projector, the projector including at least one non-transitory processor-readable storage medium communicatively coupled to at least one processor, the method comprising:

providing, by the at least one non-transitory processor-readable storage medium, projection data representing a plurality of rows of an image raster, the projection data including:
a first set of at least two data sections, the at least two data sections of the first set being different representations of a first portion of a first row in the image raster;
a second set of at least one data section, the at least one data section of the second set representing a second portion of the first row in the image raster;
and
a third set of at least two data sections, the at least two data sections of the third set being different representations of a third portion of the first row in the image raster;
generating, by the at least one processor, a data stream for a first display frame, wherein generating, by the at least one processor, the data stream for the first display frame includes:
reading, from the at least one non-transitory processor-readable storage medium by the at least one processor, one data section of the at least two data sections of the first set;
reading, from the at least one non-transitory processor-readable storage medium by the at least one processor, the at least one data section of the second set;
and
reading, from the at least one non-transitory processor-readable storage medium by the at least one processor, one data section of the at least two data sections of the third set;
and
controlling, by the at least one processor, the projector to project an image based on the data stream for the first display frame.

9 more elements

A system for processing projection data and controlling a projector, the system including a projector, at least one processor, and at least one non-transitory processor-readable storage medium communicatively coupled to the at least one processor, the at least one non-transitory processor-readable storage medium having instructions stored thereon which when executed by the at least one processor cause the system to:

for a first row of an image raster representing an image to be projected:
for a first portion of the first row:
provide, by the at least one processor, a first set of at least two data sections, the at least two data sections in the first set being different representations of the first portion of the first row;
store, by the at least one non-transitory processor-readable storage medium, the first set of at least two data sections as a first portion of the projection data;
for a second portion of the first row:
provide, by the at least one processor, a second set of at least one data section, the at least one data section of the second set representing the second portion of the first row;
and
store, by the non-transitory processor-readable storage medium, the second set of at least one data section as a second portion of the projection data;
and
for a third portion of the first row:
provide, by the at least one processor, a third set of at least two data sections, the at least two data sections of the third set being different representations of the third portion of the first row;
and
store, by the non-transitory processor-readable storage medium, the third set of at least two data sections as a third portion of the projection data;
generate, by the at least one processor, a data stream for a first display frame, wherein the instructions which cause the at least one processor to generate the data stream for the first display frame cause the system to:
read, from the at least one non-transitory processor-readable storage medium by the at least one processor, one data section of the at least two data sections of the first set;
read, from the at least one non-transitory processor-readable storage medium by the at least one processor, the at least one data section of the second set;
and
read, from the at least one non-transitory processor-readable storage medium by the at least one processor, one data section of the at least two data sections of the third set;
and
control, by the at least one processor, the projector to project an image based on the data stream for the first display frame.
