Abstract
A projector that is capable of correcting optical characteristics without degrading gradation of a projected image. The projector includes a projection optical system for projecting a projected image on a projection plane. When performing projection based on RAW data obtained through image pickup, the RAW data is corrected based on correction parameters and developed, whereby image data is generated. A projected image corresponding to the image data is projected on the projection plane.
Claims19
A projector that projects a projected image on a projection plane, comprising:
- a projection optical system configured to project the projected image on the projection plane;
- a developing unit configured to, when performing projection based on RAW data obtained through image pickup, perform, on the RAW data, correction processing based on correction parameters and development processing, to thereby generate image data;
- and
- a projection unit configured to project a projected image corresponding to the image data on the projection plane.
A projection system comprising:
- a projector that projects a projected image on a projection plane;
- and
- an image processing apparatus that transmits image data used for projection performed by the projector to the projector,
- wherein the projector includes:
- a projection optical system configured to project the projected image on the projection plane,
- a reception unit configured to receive the image data from the image processing apparatus,
- a first transmission unit configured to transmit correction parameters for correcting RAW data obtained through image pickup to the image processing apparatus, and
- a projection unit configured to project a projected image corresponding to the image data on the projection plane.
An image processing apparatus comprising:
- a developing unit configured to perform, on RAW data obtained through image pickup, correction processing based on optical characteristics of a projection optical system included in a projector that projects a projected image on a projection plane, and development processing, to thereby generate image data;
- and
- a communication unit configured to transmit the image data generated by the developing unit to the projector.
A non-transitory computer-readable storage medium storing a computer-executable program for executing a method of controlling a projector including a projection optical system for projecting a projected image on a projection plane,
- wherein the method comprises:
- performing, when performing projection based on RAW data obtained through image pickup, on the RAW data, correction processing based on correction parameters and development processing, to thereby generate image data;
- and
- projecting a projected image corresponding to the image data on the projection plane.
A non-transitory computer-readable storage medium storing a computer-executable program for executing a method of controlling an image processing apparatus,
- wherein the method comprises:
- performing, on RAW data obtained through image pickup, correction processing based on optical characteristics of a projection optical system included in a projector that projects a projected image on a projection plane, and development processing, to thereby generate image data;
- and
- transmitting the generated image data to the projector.
