Projection apparatus that projects image using laser beams, control method of the same, and storage medium

A control method of a projection apparatus which includes a first laser beam source configured to output a visible laser beam, a second laser beam source configured to output an invisible laser beam, and a scan unit configured to project an image by scanning a projection surface using the visible laser beam output from the first laser beam source and the invisible laser beam output from the second laser beam source, the method comprising:

• controlling a timing at which the first laser beam source outputs the visible laser beam and a timing at which the second laser beam source outputs the invisible laser beam so that, in a period corresponding to a target pixel in the image, the visible laser beam is output in a first period and the invisible laser beam is output in a second period different from the first period.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of a projection apparatus which includes a first laser beam source configured to output a visible laser beam, a second laser beam source configured to output an invisible laser beam, and a scan unit configured to project an image by scanning a projection surface using the visible laser beam output from the first laser beam source and the invisible laser beam output from the second laser beam source, the method comprising:

• controlling a timing at which the first laser beam source outputs the visible laser beam and a timing at which the second laser beam source outputs the invisible laser beam so that, in a period corresponding to a target pixel in the image, the visible laser beam is output in a first period and the invisible laser beam is output in a second period different from the first period.
