PROBLEM TO BE SOLVED: To provide a signal processing device and a signal processing method, which allow a user to properly grasp a situation form an image while suppressing degradation of visibility of the image due to shaking.SOLUTION: A signal processing device includes: an image extraction part which extracts, from an unprocessed image obtained by imaging, a portion corresponding to at least a part of a display object area in a holding image obtained by imaging at the time point which is before the time point of imaging of the unprocessed image; and an image generation part for generating a processed image in which a first area belongs to the unprocessed image extracted by the image extraction part, and a second area different from the first area belongs to the holding image.SELECTED DRAWING: Figure 4 【課題】振れによる画像の視認性の悪化を抑制しながら、ユーザが当該画像から状況を適切に把握することが可能な信号処理装置および信号処理方法を提供する。【解決手段】撮像により得られる未加工画像から、前記未加工画像の撮像時点より前の時点での撮像により得られた保持画像における表示対象領域の少なくとも一部に対応する部分を抽出する画像抽出部と、第１の領域が前記画像抽出部により抽出された前記未加工画像であり、前記第１の領域と異なる第２の領域が前記保持画像である、加工画像を生成する画像生成部と、を備える、信号処理装置。【選択図】図４
