Abstract
Provided is a projection system including an image processor processing image data, the image processor acquires subsequent image data having an object included in an image temporarily subsequent to an image currently displayed by the projector. The projector stores the image data and the subsequent image data and updates the currently displayed image into the subsequent image on the basis of the subsequent image data when the update information received by the projector reception unit indicates that the currently displayed image is updated into the subsequent image.
Claims8
A projection system comprising:
- an image processor processing image data;
- a projector modulating a light beam emitted from a light source device on the basis of the image data processed by the image processor;
- and
- an information transmitting unit connecting the image processor and the projector to each other so as to transmit and receive information therebetween,
- wherein the image processor includes:
- a predicting unit predicting a subsequent image in a presentation sequence that is temporarily subsequent to an image currently displayed by the projector, wherein the presentation sequence is a previously set sequence;
- a transmitting unit transmitting subsequent image data which corresponds to the subsequent image predicted by the predicting unit;
- an operation signal detecting unit detecting an operation signal, which indicates that the currently displayed image is updated into a predetermined image, after the transmitting unit transmitted the subsequent image data;
- an update image judging unit comparing the predetermined image with the predicted subsequent image other than the currently displayed image;
- an update information generating unit capable of generating update information indicating that the currently displayed image is updated into either one of the predicted subsequent image other than the currently displayed image and an image other than the predicted subsequent image on the basis of the comparison result of the update image judging unit;
- an update information transmitting unit transmitting the update information;
- and
- wherein the projector includes:
- a projector reception unit receiving the subsequent image data and the update information;
- a storage unit capable of storing a plurality of the subsequent image data;
- a display control unit displaying an image based on the image data;
- and
- an image update unit updating the currently displayed image into the predicted subsequent image on the basis of the subsequent image data when the update information received by the projector reception unit indicates that the currently displayed image is updated into the predicted subsequent image.
An image processor which is connected to a projector so as to transmit and receive information therebetween through an information transmitting unit and which processes image data, the image processor comprising:
- an image data acquiring unit acquiring the image data;
- a predicting unit predicting a subsequent image in a presentation sequence that is temporarily subsequent to an image currently displayed by the projector unit, wherein the presentation sequence is a previously set sequence:
- a transmitting unit transmitting subsequent image data which corresponds to the subsequent image predicted by the predicting unit;
- an operation signal detecting unit detecting an operation signal, which indicates that the currently displayed image is updated into a predetermined image, after the transmitting unit transmitted the subsequent image data;
- an update image judging unit comparing the predetermined image with the predicted subsequent image other than the currently displayed image;
- an update information generating unit capable of generating update information indicating that the currently displayed image is updated into either one of the predicted subsequent image other than the currently displayed image and an image other than the predicted subsequent image on the basis of the comparison result of the update image judging unit;
- and
- an update information transmitting unit transmitting the update information.
An image processing method of processing image data in an image processor connected to a projector so as to transmit and receive information therebetween through an information transmitting unit, the image processing method comprising:
- predicting subsequent image data having an object included in an image temporarily subsequent in a presentation sequence to an image currently displayed by the projector, wherein the presentation sequence is a previously set sequence;
- transmitting the subsequent image data which corresponds to the subsequent image predicted by the predicting unit;
- detecting an operation signal, which indicates that the currently displayed image is updated into a predetermined image, after transmitting the subsequent image data;
- comparing the predetermined image with the predicted subsequent image other than the currently displayed image;
- generating update information indicating that the currently displayed image is updated into either one of the predicted subsequent image other than the currently displayed image and an image other than the predicted subsequent image on the basis of the comparison result;
- transmitting the update information.
