IMAGING DEVICE, IMAGING SYSTEM, AND IMAGING METHOD

To make it possible to accurately detect and track a moving object and output a region of interest including the moving object at high resolution without increasing power consumption.SOLUTION: An imaging device includes: a pixel array unit that has a plurality of pixel circuits, and can clip a first pixel region which is a part of an effective pixel region and output pixel data in the first pixel region; and a signal processing unit that detects and tracks a moving object in the first pixel region on the basis of the pixel data output from the pixel array unit in the first pixel region, clips a second pixel region which is a part of the first pixel region, and outputs pixel data in the second pixel region.SELECTED DRAWING: Figure 1 【課題】消費電力を増やすことなく、動体を精度よく検出及び追尾可能で、かつ動体を含む関心領域を高解像で出力する。【解決手段】撮像装置は、複数の画素回路を有し、有効画素領域の一部である第１画素領域を切り出して、第１画素領域内の画素データを出力可能な画素アレイ部と、画素アレイ部から出力された第１画素領域内の画素データに基づいて、第１画素領域内で動体の検出及び追尾を行うとともに、第１画素領域の一部である第２画素領域を切り出して、第２画素領域内の画素データを出力する信号処理部と、を備える。【選択図】図１
