Abstract
A personal computer includes an output interface configured to output an image signal to a projector, an image processing section configured to generate a second image obtained by reducing visibility of the first image, and a second control section configured to, when a first condition is satisfied, cause the output interface to output a second image signal based on the second image and, when a second condition is satisfied, cause the output interface to output a first image signal based on the first image.
Claims11
An image supply device that outputs an image signal, the image supply device comprising:
- an interface circuit configured to output the image signal to a display device different from the image supply device;
- an integrated circuit configured to generate a second image obtained by reducing visibility of a first image;
- and
- a processor programmed to, when a first condition is satisfied, cause the interface circuit to output a second image signal based on the second image and, when a second condition is satisfied, cause the interface circuit to output a first image signal based on the first image,
- wherein the first condition is that the processor determines that the display device is coupled to the interface circuit, so that the second image signal based on the second image is directly output to the display device for display of the second image without any prior display of the first image,
- wherein the processor is further programmed for switching an operation state of the image supply device to a first operation state corresponding to a mirroring mode and a second operation state corresponding to an extension mode,
- wherein when the image supply device is in the first operation state, the processor causes the interface circuit to output the second image signal when the first condition is satisfied, and
- wherein when the image supply device is in the second operation state, the processor causes the interface circuit to output the first image signal without causing the interface circuit to output the second image signal.

A display system comprising:
- a display device including a display section;
- and
- an image supply device configured to output an image signal to the display device, the image supply device including:
- an interface circuit configured to output the image signal to the display device;
- an integrated circuit configured to generate a second image obtained by reducing visibility of a first image;
- and
- a processor configured to, when a first condition is satisfied, cause the interface circuit to output a second image signal based on the second image and, when a second condition is satisfied, cause the interface circuit to output a first image signal based on the first image,
- wherein the first condition is that the processor determines that the display device is coupled to the interface circuit, so that the second image signal based on the second image is directly output to the display device for display of the second image without any prior display of the first image,
- wherein the processor is further programmed for switching an operation state of the image supply device to a first operation state corresponding to a mirroring mode and a second operation state corresponding to an extension mode,
- wherein when the image supply device is in the first operation state, the processor causes the interface circuit to output the second image signal when the first condition is satisfied, and
- wherein when the image supply device is in the second operation state, the processor causes the interface circuit to output the first image signal without causing the interface circuit to output the second image signal.
