Frame rate conversion processing apparatus, frame rate conversion processing method, and storage medium

摘要

A frame rate conversion processing system can generate a second row of frames that is different from a first row of frames in the number of frames. The frame rate conversion processing system includes a luminance change detection unit configured to calculate a luminance change value of the first row of frames based on luminance changes in the entire area or a partial area of the frames that constitutes the first row of frames and configured to compare the calculated luminance change value with a predetermined value. The frame rate conversion processing system further includes a correction unit configured to correct the luminance of the entire area or a partial area of the frames that constitutes the second row of frames according to a comparison result obtained by the luminance change detection unit.

1. A frame rate conversion processing apparatus that converts an input image signal having a first frame rate into a converted image signal having a second frame rate, in which the second frame rate is lower than the first frame rate, the frame rate conversion processing apparatus comprising:
a detection unit configured to detect a frequency of temporal changes in luminance of the input image signal; and an outputting unit configured to output, when the detection unit detects that the frequency of the temporal changes in luminance of the input image signal exceeds a predetermined frequency of temporal changes in luminance that can be perceived by human eyes, the converted image signal having the second frame rate of which temporal changes in luminance are controlled so as to prevent the temporal changes in luminance of the converted image signal from being perceived by human eyes and to output, when the detection unit detects that the frequency of the temporal changes in luminance of the input image signal does not exceed the predetermined frequency of temporal changes in luminance that can be perceived by human eyes, the converted image signal having the second frame rate of which temporal changes in luminance can be perceived by human eyes.
