Abstract: A candidate image presenting method using thumbnail images and an image signal processor and an imaging device performing the candidate image presenting method are provided. The image signal processing device processes a plurality of original image data by frames to generate a plurality of frame image data, generates and firstly outputs a plurality of thumbnail image data corresponding to the plurality of frame image data, and secondly outputs the frame image data corresponding to the thumbnail image data selected on the basis of a selection signal. Accordingly, it is possible to enable an image to be captured in a suitable photographing mode without missing a desired instant by providing a user with thumbnail images obtained by means of photographing operations in various photographing modes for a short time and causing a user to select a desired frame image on the basis of the thumbnail images.
