Patent ID: 8040380

Claim:
An image-taking apparatus that generates an image representing a subject by using an imaging device, the image-taking apparatus comprising: a shooting section that generates an image by shooting; a shooting control section that causes the shooting section to generate a plurality of continuously shot images in response to a shooting operation; a preprocessing section that causes a predetermined memory to store one of the plurality of continuously shot images generated by the shooting section, and that performs amplifying processing by a predetermined gain on the plurality of continuously shot images generated by the shooting section to output the plurality of continuously shot images on which the amplifying processing is performed; a superimposing section that receives the plurality of continuously shot images, on which the amplifying processing is performed by the preprocessing section and which are output from the preprocessing section, and that superimposes the received plurality of continuously shot images on each other so that blurring is corrected, thereby generating one superimposed image; a high-sensitivity image generation section that generates a high-sensitivity image which has higher sensitivity than sensitivity of the received plurality of continuously shot images, by performing amplifying processing by a larger gain than the predetermined gain on the one of the plurality of continuously shot images stored by the predetermined memory after the plurality of continuously shot images are output from the preprocessing section to the superimposing section; a signal processing section that performs predetermined signal processing including color separating processing and YC conversion processing on the high-sensitivity image generated by the high-sensitivity image section while the superimposing section is generating the one superimposed image, wherein when the superimposing section finishes generating the one superimposed image, the signal processing section also performs the predetermined signal processing on the one superimposed image; and an image recording section that records both the superimposed image, on which the predetermined signal processing is performed, and the high-sensitivity image, on which the predetermined signal processing is performed.
