1. A display apparatus comprising:
a display having a light emitting section including a plurality of light emitting elements; and
circuitry configured to:
detect a feature amount of a video content;
control driving of the light emitting section of the display displaying the video content; and
control an on period and a current value for at least one of the plurality of light emitting elements in the light emitting section based on the feature amount of the video content,
wherein the on period for the at least one of the plurality of light emitting elements in the light emitting section is controlled by changing a driving frequency for impulse driving based on the feature amount of the video content, and
wherein integration of brightness of the at least one of the plurality of light emitting elements in the light emitting section is substantially the same before and after a change in driving frequency,
wherein
the display includes a self-luminous display section,
the plurality of light emitting elements in the light emitting section includes self-luminous elements,
the self-luminous elements are provided for subpixels included in pixels two-dimensionally arranged in the self-luminous display section,
the circuitry is configured to control the on period and the current value for the self-luminous elements, and
the circuitry is configured to suppress the impulse driving performed on the light emitting section in a case where the pixels, for which the applied current is larger than a threshold, satisfy a condition.
