1. A display control apparatus comprising:

  • at least one hardware processor; and

    a memory which stores instructions executable by the at least one hardware processor to cause the display control apparatus to perform;

    increasing pixel values of a plurality of predetermined positions on a first image based on an image frame of an inputted image signal;

    decreasing pixel values of the plurality of predetermined positions, which are the same as positions where the pixel values of the first image are increased in the increasing, on a second image based on the image frame;

    performing projection control to control a projection unit so that N image frames, which are based on the image frame and include both the first image whose pixel values of the predetermined positions have been increased in the increasing and the second image whose pixel values of the predetermined positions have been decreased in the decreasing, are projected at a frequency that is N-times a frame frequency according to the inputted image signal, wherein N is greater than 1;

    acquiring, based on a captured image obtained by a capturing unit for capturing a projection surface where an image is projected according to the projection control, a parameter for adjusting an image to be projected by the projection unit; and

    performing adjustment processing for adjusting, based on the parameter acquired in the acquiring, the image to be projected on the projection surface by the projection unit.
