Transmitting apparatus, stereoscopic image data transmitting method, receiving apparatus, and stereoscopic image data receiving method

A stereoscopic image data transmitting method, comprising the steps of:

• acquiring information related to a screen size from an external device through a transmission path;
• and
• transmitting stereoscopic image data, including left-eye image data and right-eye image data for displaying a stereoscopic image, to the external device through the transmission path,
• wherein
• one frame of the stereoscopic image data is transmitted during a time between one vertical synchronizing signal of a signal transmitted in the step of transmitting and the next vertical synchronizing signal of a signal transmitted in the step of transmitting,
• the left-eye image data and the right-eye image data in the one frame are transmitted in a predetermined order,
• the number of lines and number of pixels of the left-eye image data during transmitting of the left-eye image data are the same as the number of lines and the number of pixels displayed during displaying of the left-eye image data, and the number of lines and number of pixels of the right-eye image data during transmitting of the right-eye image data are the same as the number of lines and the number of pixels displayed during displaying of the right-eye image data,
• there is an interval of time between transmission of the left-eye image data and transmission of the right-eye image data, and
• no image data for displaying a stereoscopic image is transmitted during the interval of time between transmission of the left-eye image data and transmission of the right-eye image data.

A transmitting apparatus comprising:

• an acquiring unit that acquires information related to a screen size from an external device through a transmission path;
• and
• a transmitting unit that transmits stereoscopic image data, including left-eye image data and right-eye image data for displaying a stereoscopic image, to the external device through the transmission path,
• wherein
• one frame of the stereoscopic image data is transmitted during a time between one vertical synchronizing signal of a signal transmitted by the transmitting unit and the next vertical synchronizing signal of a signal transmitted by the transmitting unit,
• the left-eye image data and the right-eye image data in the one frame are transmitted in a predetermined order,
• the number of lines and number of pixels of the left-eye image data during transmitting of the left-eye image data are the same as the number of lines and the number of pixels displayed during displaying of the left-eye image data, and the number of lines and number of pixels of the right-eye image data during transmitting of the right-eye image data are the same as the number of lines and the number of pixels displayed during displaying of the right-eye image data,
• there is an interval of time between transmission of the left-eye image data and transmission of the right-eye image data, and
• no image data for displaying a stereoscopic image is transmitted during the interval of time between transmission of the left-eye image data and transmission of the right-eye image data.
