Abstract: An image sensing apparatus including an image sensor having a first area and a second area and a gradation converter for applying a gradation conversion to an image signal is provided with a gradation conversion LUT storage storing at least two kinds of gradation conversion information. The image sensing apparatus is also provided with a gradation conversion information rewriting section for rewriting the gradation conversion information into new gradation conversion information. There can be provided an image sensing apparatus capable of carrying out a precise gradation conversion even in the case that the inflection point between the first area and the second area of the image sensor constantly changes.

Abstract: An image sensing apparatus including an image sensor having a first area and a second area and a gradation converter for applying a gradation conversion to an image signal is provided with a gradation conversion LUT storage storing at least two kinds of gradation conversion information including a first gradation conversion characteristic, which is gradation conversion information for the first area, and a second gradation conversion characteristic, which is gradation conversion information for the second area, the first and second gradation conversion characteristics having a switching point at an inflection pint between the first area and the second area of the image sensor. The image sensing apparatus is also provided with a gradation conversion information rewriting section for rewriting the gradation conversion information into new gradation conversion information whose switching point is changed in conformity with the inflection point after a change in the case that the inflection point is changed.
