Display device and control method for the display device

摘要

A projector displays, together with an input image, an OSD image different from the input image. The projector includes an image output unit configured to output image data of an image for the left eye and image data of an image for the right eye, an image processing unit configured to read out a different image data from a RAM, apply, to the image data of the image for the left eye, processing for arranging the different image data in a position for the left eye and combining the different image data with the image data of the image for the left eye, and apply, to the image data of the image for the right eye, processing for arranging the different image data in a position for the right eye and combining the different image data with the image data of the image for the right eye.

1. A display device that displays, on the basis of input image data, a stereoscopic image including an image for a left eye and an image for a right eye, the display device comprising:
an image output unit configured to output image data of the image for the left eye and image data of the image for the right eye on the basis of the input image data; a buffer configured to temporarily store the image data output by the image output unit; a memory configured to store different image data, which is image data different from the input image data; an image processing unit configured to read out the different image data stored in the memory, apply, to the image data of the image for the left eye in the image data stored in the buffer, processing for arranging the different image data in a position for the left eye and combining the different image data with the image data of the image for the left eye, and apply, to the image data of the image for the right eye in the image data stored in the buffer, processing for arranging the different image data in a position for the right eye and combining the different image data with the image data of the image for the right eye; and a display unit configured to display an image on the basis of image data for the left eye and image data for the right eye processed by the image processing unit, wherein:
the image output unit alternately outputs the image data of the image for the left eye and the image data of the image for the right eye to the buffer,the image output unit, in synchronization with the output image data, outputs a vertical synchronization signal and an identification signal to the image processing unit,the identification signal indicates whether the image data being output is the data of the image for the left eye or the data of the image for the right eye, andthe image processing unit includes a position determining unit to determine the position for the left eye and the position for the right eye on the basis of the identification signal.
