Information processing system, information processing apparatus, output apparatus, program, and recording medium
To solve a problem that when there is an error in a mounting position in mounting a lens and thus an optical axis of the lens and a center of a display is shifted, centers of images seen by the left and right eyes of a user individually, are shifted and thus an intended sense of distance cannot be presented to the user. An output apparatus includes a display portion including a plurality of sub-pixels every pixel, and a lens arranged on a display surface side of the display portion, and outputs information on an assembly error representing position shift between an optical axis of the lens and a center of the display portion. An information processing apparatus produces corrected image data obtained by correcting image data becoming an object of display based on the information on the assembly error output from the output apparatus.
1. An information processing system comprising:
a head-mounted display; and
an information processing apparatus,
the head-mounted display including:
a display portion including a plurality of sub-pixels every pixel,
a lens arranged on a display surface side of the display portion, the lens including an inherent distortion, and
a circuit operating to output information on an assembly error representing a fixed position shift between an optical axis of the lens and a center of the display portion measured at a time of manufacturing the head-mounted display,
the information processing apparatus serving to acquire the information on the assembly error from the head-mounted display, and the information processing apparatus including:
a corrected image data producing circuit operating to: (i) produce first corrected image data from source image data such that the first corrected image data compensates for the inherent distortion of the lens, and (ii) produce second corrected image data from the first corrected image data by moving the first corrected image data an equal and opposite shift as the fixed position shift based on the information on the assembly error acquired, and
a circuit operating to output the second corrected image data produced by the corrected image data producing circuit to the head-mounted display,
wherein the head-mounted display displays the second corrected image data output from the information processing apparatus on the display portion.
2. An information processing apparatus operable for communicating with a head-mounted display, including a display portion including a plurality of sub-pixels every pixel, a lens arranged on a display surface side of the display portion, the lens including an inherent distortion, and the head-mounted display outputting information on an assembly error representing a fixed position shift between an optical axis of the lens and a center of the display portion measured at a time of manufacturing the head-mounted display, the information processing apparatus serving to produce an image to be displayed on the display portion, and the information processing apparatus comprising:
a corrected image data producing circuit operating to: (i) produce first corrected image data from source image data such that the first corrected image data compensates for the inherent distortion of the lens, and (ii) produce second corrected image data from the first corrected image data by moving the first corrected image data an equal and opposite shift as the fixed position shift based on the information on the assembly error acquired; and
a circuit operating to output the second corrected image data produced by the corrected image data producing circuit to the head-mounted display.
3. The information processing apparatus according to claim 2 , further comprising:
a memory operating to store information on the assembly error, representing the position shift between the optical axis of the lens and the center of the display portion, obtained through measurement,
wherein the circuit operating to output outputs the information on the assembly error stored in the memory.
4. The information processing apparatus according to claim 2 , further comprising:
a measurement circuit operating to measure the assembly error representing the position shift between the optical axis of the lens and the center of the display portion,
wherein the circuit operating to output outputs the information on the assembly error measured by the measurement circuit.
5. A non-transitory, computer readable recording medium storing a computer program, which when executed by an information processing apparatus, causes the information processing apparatus to carry out actions, where the information processing apparatus is operable for communicating with a head-mounted display, including a display portion including a plurality of sub-pixels every pixel, a lens arranged on a display surface side of the display portion, the lens including an inherent distortion, and the head-mounted display outputting information on an assembly error representing a fixed position shift between an optical axis of the lens and a center of the display portion measured at a time of manufacturing the head-mounted display, the information processing apparatus serving to produce an image to be displayed on the display portion, the actions, comprising:
producing first corrected image data from source image data such that the first corrected image data compensates for the inherent distortion of the lens,
producing second corrected image data from the first corrected image data by moving the first corrected image data an equal and opposite shift as the fixed position shift based on the information on the assembly error acquired; and
outputting the second corrected image data produced by the corrected image data producing means to the head-mounted display.
