Claim One:
1. A display control apparatus comprising: a hardware processor; and a memory which stores instructions to be executed by the hardware processor, wherein the instructions, when executed by the hardware processor, cause the display control apparatus to: generate an added frame by adding pixel values of a predetermined image pattern to pixel values of a first frame based on a frame of an inputted image signal and generate a subtracted frame by subtracting the pixel values of the predetermined image pattern from pixel values of a second frame based on the frame of the inputted image signal; perform projection control to control a projection unit so that N frames, which are based on the frame of the inputted image signal and include the added frame and the subtracted frame, are projected at N-times a frame frequency of the inputted image signal, wherein N is greater than 1; acquire a parameter based on a captured image obtained by a capturing unit capturing an image projected, according to the projection control, on a screen; and perform correction control to control, based on the parameter acquired in the acquiring, correction for a shape of an image projected on the screen by the projection unit.
