Abstract:
1. A capturing device comprising: an image sensor that performs photoelectric conversion on light from a subject and generates an image signal at a first frame rate; a storage unit that has a first region for storing a first image signal corresponding to a full image from the image signal input from the image sensor and a second region for storing a second image signal corresponding to a specified image specified by a set value for enlarging an image from the image signal; a timing adjusting unit that adjusts a timing at which the image signal is read out from the image sensor to write the image signal in the storage unit, and a timing at which the image signal is read out from the storage unit; an image conversion processing unit that performs a predetermined process on the image from the image signal read out from the image sensor and alternately writes the first image signal corresponding to the full image and the second image signal corresponding to a partial image which corresponds to the specified image every one frame according to the timings adjusted by the timing adjusting unit; an output unit that converts the first and second image signals read out from the first and second regions at continuous scanning timings into an image signal in a predetermined format and outputs the converted image signals; and a display control unit that controls the image conversion processing unit to write the first image signal of a given frame of the full image into the first region of the first region of the storage unit and to write the second image signal of a different frame of the partial image into the second region of the storage unit, wherein the first and second image signals are read out from the first and second regions, respectively, of the storage unit at a second frame rate reduced by half of the first frame rate.
