Abstract
A projection apparatus executes a first processing and a second processing on image signal received from an external device, projects an image based on the image signal processed by an image processor, and switches an operation mode of the projection apparatus to a first mode, which is a low-latency mode for suppressing a delay in displaying an image, and a second mode, which is not the low-latency mode. The image processor maintains the first processing and stops the second processing in response that the operation mode of the projection apparatus is switched to the first mode from a state in which the operation mode is the second mode and the first processing and the second processing are executed.
Claims17
A projection apparatus comprising:
- a communication unit configured to communicate with an external device;
- an image processor capable of executing a first processing including at least one of a deformation, a rotation and an inversion, and a second processing other than the first processing, on image signal received from the external device via the communication unit;
- a projection unit configured to project an image based on the image signal processed by the image processor;
- and
- a control unit configured to switch a projection operation mode of the projection apparatus to one of a plurality of projection operation modes including a first projection mode, which is a low-latency projection mode for suppressing a delay in displaying an image, and a second projection mode, which is not the low-latency projection mode,
- wherein the image processor maintains the first processing and stops the second processing in response that the projection operation mode of the projection apparatus is switched to the first projection mode from a state in which the projection operation mode of the projection apparatus is the second projection mode and the first processing and the second processing are executed.
A method of controlling a projection apparatus which communicates with an external device, comprising:
- executing image processing including a first processing including at least one of a deformation, a rotation and an inversion, and a second image processing other than the first processing, on the image signal received from the external device;
- projecting an image based on the image signal on which the image processing has been executed;
- and
- switching a projection operation mode of the projection apparatus to one of a plurality of projection operation modes including a first projection mode, which is a low-latency projection mode for suppressing a delay of an image display, and a second projection mode, which is not the low-latency projection mode,
- wherein in the image processing, the first processing is maintained and the second processing is stopped in response that the projection operation mode of the projection apparatus is switched to the first projection mode from a state in which the projection operation mode of the projection apparatus is the second projection mode and the first processing and the second processing are executed.
A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method of controlling a projection apparatus which communicates with an external device, comprising:
- executing image processing including a first processing including at least one of a deformation, a rotation and an inversion, and a second image processing other than the first processing, on the image signal received from the external device;
- projecting an image based on the image signal on which the image processing has been executed;
- and
- switching a projection operation mode of the projection apparatus to one of a plurality of projection operation modes including a first projection mode, which is a low-latency projection mode for suppressing a delay of an image display, and a second projection mode, which is not the low-latency projection mode,
- wherein in the image processing, the first processing is maintained and the second processing is stopped in response that the projection operation mode of the projection apparatus is switched to the first projection mode from a state in which the projection operation mode of the projection apparatus is the second projection mode and the first processing and the second processing are executed.
