Abstract
(EN)
This image-capturing element has a processing circuit and a memory embedded therein. The memory stores captured image data obtained by capturing images of a subject at a first frame rate. The processing circuit performs processing based on the captured image data stored in the memory. An output circuit outputs output image data based on the captured image data outside the image-capturing element at a second frame rate. The first frame rate is higher than the second frame rate, and is determined according to a flickering period. The processing circuit detects a flicker influence avoiding timing at which a flicker influence is avoided for image-capturing by the image-capturing element on the basis of captured image data of a plurality of frames.

Cet élément de capture d'image comporte un circuit de traitement et une mémoire intégrée à l'intérieur de celui-ci. La mémoire stocke des données d'image capturées obtenues par capture d'images d'un sujet à une première fréquence de trame. Le circuit de traitement effectue un traitement sur la base des données d'image capturées stockées dans la mémoire. Un circuit de sortie délivre des données d'image de sortie sur la base des données d'image capturées à l'extérieur de l'élément de capture d'image à une seconde fréquence de trame. La première fréquence de trame est supérieure à la seconde fréquence de trame, et est déterminée en fonction d'une période de scintillement. Le circuit de traitement détecte une influence de scintillement évitant la synchronisation au moment où une influence de scintillement est évitée pour une capture d'image par l'élément de capture d'image sur la base de données d'image capturées d'une pluralité de trames.

撮像素子は、処理回路及びメモリを内蔵している。メモリは、被写体が第1フレームレートで撮像されることにより得られた撮像画像データを記憶する。処理回路は、メモリに記憶された撮像画像データに基づく処理を行う。出力回路は、撮像画像データに基づく出力用画像データを第2フレームレートで撮像素子の外部に出力する。第1フレームレートは、第2フレームレートよりも高いフレームレートであり、かつ、フリッカの発生周期に応じて定められ、処理回路は、複数フレーム分の撮像画像データに基づいて、撮像素子による撮像に対してのフリッカの影響が回避されるフリッカ影響回避タイミングを検出する。
