Display system and display method using imaging apparatus and projection video display apparatus

A display system comprising:

• an imaging apparatus that takes a video by shifting pixels in units of frames by moving a solid state image sensing device or an optical member physically;
• and
• a projection video display apparatus that acquires a video taken by the imaging apparatus, optically performs pixel shift corresponding to pixel shift performed in the imaging apparatus at the time of imaging, and projects the video acquired, wherein
• the projection video display apparatus transmits setting information to the imaging apparatus, the setting information designating a direction and amount of pixel shift performed in the imaging apparatus, and
• the imaging apparatus performs pixel shift based on the setting information received.

A display method comprising:

• taking a video by shifting pixels in units of frames by moving a solid state image sensing device or an optical member physically;
• and
• acquiring a video taken, optically performing pixel shift corresponding to pixel shift performed at the time of imaging, and projecting the video acquired to a projection surface,
• wherein the taking the video by the shifting pixels includes:
• the solid state image sensing device or the optical member is shifted to n positions sequentially, wherein n is an integer equal to or greater than 2, and
• producing video data that include frame images taken at the n positions in one vertical synchronization period;
• and
• wherein the projecting the video includes projecting the n frame images included in the one vertical synchronization period to the n positions of projection sequentially.
