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.

Abstract
A display control apparatus which projects and displays at least one image on a screen, converts a frame frequency for a display of the at least one image to N times (N>1), generates an added image by adding a predetermined pattern to the converted frame and a subtracted image by subtracting the predetermined pattern from the converted frame as a first frame and a second frame following the first frame, projects the generated first frame and the second frame for an image on the screen at the N-times frequency, acquires the image projected on the screen, extracts the pattern from the acquired image, and corrects a shape of the image based on the extracted pattern.
