Position correction in handheld image translation device
View Patent ↗Systems, apparatuses, and methods for correcting position in a handheld image translation device are described herein. The handheld image translation device may include a position module to determine a first position of the device and a print module to deposit a printing substance on a medium adjacent to the device based at least in part on the position. The device may also include an image capture module to capture surface images of the section of the medium with printing substance deposited thereon. These surface images may be used by the position module to determine subsequent positions of the device. Other embodiments may be described and claimed.
1. An apparatus comprising:

an image capture module configured to control an optical imaging sensor to capture a surface image of a section of the medium having the deposited printing substance;
wherein the position module is further configured to
compare the captured surface image of the section of the medium with a portion of an image stored in the memory, and
determine a second position of the apparatus relative to the medium based at least in part on the comparison,
wherein the print head comprises one or more nozzle rows, and
wherein the optical imaging sensor includes a linear array of optical elements having a linear dimension that is similar to a linear dimension of the print head.
2. The apparatus of claim 1 , further comprising:
a communication interface configured to receive the image from an image source; and
an image processing module configured to process the image prior to the image being translated to the medium.
3. The apparatus of claim 1 , wherein the position module is configured to periodically determine other positions of the apparatus based at least in part on other captured surface images.
4. The apparatus of claim 1 , wherein the position module is configured to determine the position of the apparatus relative to a reference location.
5. An apparatus comprising:
a memory configured to store an image to be translated onto a medium;
an optical imaging sensor;
one or more navigational sensors;
a print head;
a control block configured to
control the one or more navigational sensors to determine a first position of the apparatus relative to the medium;
control the print head to deposit a printing substance on the medium based at least in part on the determined first position of the apparatus relative to the medium;
control the optical imaging sensor to capture a surface image of a section of the medium having the deposited printing substance;
determine a second position of the apparatus relative to the medium based at least in part on comparing the captured surface image with the image stored in the memory,
wherein the print head comprises one or more nozzle rows, and
wherein the optical imaging sensor includes a linear array of optical elements haying a linear dimension that is similar to a linear dimension of the print head.
6. The apparatus of claim 5 , wherein the optical imaging sensor comprises a first plurality of pixels in a first direction and a second plurality of pixels in a second direction.
7. The apparatus claim 5 , wherein a first nozzle row of the one or more nozzle rows is arranged on a first side of the linear array of optical elements and a second nozzle row of the one or more nozzle rows is arranged on a second side of the linear array of optical elements.
8. The apparatus of claim 5 , further comprising:
a plurality of balls disposed within respective capture cages configured to space the apparatus a distance from an adjacent medium.
9. A method comprising:
determining a first position of an image translation device relative to a medium;
depositing, via a print head, a printing substance on the medium based at least in part on the determined first position of the image translation device relative to the medium;
capturing, by an optical imaging sensor, a surface image of a section of the medium having the deposited printing substance;
accessing an image from memory of the image translation device, wherein the image is to be translated onto the medium;
comparing the captured surface image with a portion of the image accessed from the memory; and
determining a second position of the image translation device relative to the medium based at least in part on comparing the captured surface image with the portion of the image accessed from the memory,
wherein the print head comprises one or more nozzle rows, and
wherein the optical imaging sensor includes a linear array of optical elements having a linear dimension that is similar to a linear dimension of the print head.
10. An apparatus comprising:
means for storing an image to be translated onto a medium;
means for determining a first position of the apparatus relative to the medium;
means for depositing a printing substance on the medium based at least in part on the determined first position of the apparatus relative to the medium, wherein the means for depositing comprises a print head;
means for capturing a surface image of a section of the medium having the deposited printing substance, wherein the means for capturing comprises an optical imaging sensor; and
means for determining a second position of the apparatus relative to the medium based at least in part on comparing the captured surface image with the stored image,
wherein the print head comprises one or more nozzle rows, and
wherein the optical imaging sensor includes a linear array of optical elements having a linear dimension that is similar to a linear dimension of the print head.
11. A non-transitory machine-accessible medium having associated instructions, which when executed results in an apparatus:
storing an image to be translated onto a medium;
determining a first position of the apparatus relative to the medium;
depositing, via a print head, a printing substance on the medium based at least in part on the determined first position of the apparatus relative to the medium;
capturing, using an optical imaging sensor, a surface image of a section of the medium having the deposited printing substance; and
determining a second position of the apparatus relative to the medium based at least in part on comparing the captured surface image with the stored image,
wherein the print head comprises one or more nozzle rows, and
wherein the optical imaging sensor includes a linear array of optical elements having a linear dimension that is similar to a linear dimension of the print head.
