Data processing device, data processing method, and program

A data processing device comprising:

• a frame data generation unit configured to generate frame data on a basis of event data indicating a variation in an electrical signal of a pixel generating the electrical signal by performing photoelectric conversion, the event data occurring during an accumulation time from a frame generation start time to a frame generation end time;
• and
