Projector with on screen display adjustment and control method thereof
View Patent ↗A projector includes: an OSD processing section that generates a synthesized image formed by synthesizing an OSD image on a main image; an image projecting section that projects and displays the synthesized image; a zoom adjusting section that adjusts a zoom state of the image projecting section; and a zoom state detecting section that detects the zoom state that is adjusted by the zoom adjusting section, wherein the OSD processing section adjusts a size of the OSD image with respect to the main image based on the detection result of the zoom state detecting section.
1. A projector comprising:
an OSD processing section configured to generate a synthesized image formed by synthesizing an OSD image on a main image;
an image projecting section configured to project the synthesized image;
a zoom adjusting section configured to adjust a zoom state of the image projecting section; and
a zoom state detecting section configured to detect the zoom state that is adjusted by the zoom adjusting section,
wherein the OSD processing section adjusts a size of the OSD image with respect to the main image based on the detection result of the zoom state detecting section, and
the OSD processing section enlarges the size of the OSD image with respect to the main image in a case where the zoom state is changed from a wide side to a tele side, and reduces the size of the OSD image with respect to the main image in a case where the zoom state is changed from a tele side to a wide side.
2. The projector according to claim 1 , wherein the OSD processing section adjusts the size of the OSD image with respect to the main image so that the projected OSD image is displayed constantly regardless of the zoom state.
3. The projector according to claim 1 , wherein
the zoom state detecting section detects the zoom state at a predetermined time interval, and
the OSD processing section adjusts a size of the OSD image based on the zoom state while the OSD image is synthesized on the main image.
4. A method of controlling a projector including an OSD processing section configured to generate a synthesized image formed by synthesizing an OSD image on a main image, an image projecting section configured to project and displays the synthesized image, and a zoom adjusting section configured to adjust a zoom state of the image projecting section, the method comprising:
detecting a zoom state that is adjusted by the zoom adjusting section, and
adjusting a size of the OSD image with respect to the main image based on the detection result in the detecting of a zoom state,
wherein in the adjusting of the size, the size of the OSD image with respect to the main image is enlarged in a case where the zoom state is changed from a wide side to a tele side, and the size of the OSD image with respect to the main image is reduced in a case where the zoom state is changed from a tele side to a wide side.
5. The method according to claim 4 , wherein in the adjusting of a size, the size of the OSD image with respect to the main image is adjusted so that the projected OSD image is displayed constantly regardless of the zoom state.
6. The method according to claim 4 , wherein
the detecting step detects the zoom state at a predetermined time interval, and
the adjusting step adjusts the size of the OSD image based on the zoom state while the OSD image is synthesized on the main image.
