Image taking apparatus
View Patent ↗An image taking apparatus according to the present invention has: a primary CCD section that receives a predetermined first part of object light focused by an image-taking optical system to produce a primary image signal; a secondary CCD section that has a dynamic range wider than that of the primary CCD section and receives a second part of the object light excluding the first part to produce a secondary image signal; an image signal processing circuit that produces image data based on a synthetic signal produced by synthesizing the primary image signal and the secondary image signal if the synthetic signal, rather than the primary image signal, is selected; and an information adding section that adds predetermined additional information to the image data if the image signal processing circuit produces the image data based on the synthetic signal.
1. An image taking apparatus, comprising:
an image-taking optical system that focuses object light from an object to form an image;
a primary image pick-up section that receives a predetermined first part of the object light focused by the image-taking optical system to produce a primary image signal;
a secondary image pick-up section that has a dynamic range wider than that of the primary image pick-up section and receives a second part of the object light excluding the first part to produce a secondary image signal;
an image signal synthesizing section that synthesizes the primary image signal and the secondary image signal to produce a synthetic signal;
a selector section that selects any one of the primary image signal and the synthetic signal;
an image data producing section that produces image data representing an image of the object based on the primary image signal if the selector section selects the primary image signal or produces image data representing an image of the object based on the synthetic signal if the selector section selects the synthetic signal; and
an information adding section that adds predetermined additional information to the image data if the selector section selects the synthetic signal.
2. The image taking apparatus according to claim 1 , wherein the additional information added to the image data by the information adding section is correction inhibiting information that indicates that a predetermined image correction of the image data is inhibited.
3. The image taking apparatus according to claim 1 , wherein the additional information added to the image data by the information adding section is attribute information that indicates that the image data is image data produced based on the synthetic signal.
