Patent ID: 8842187

Claim:
An image processing device comprising a high dynamic range synthesizing circuit configured to synthesize a first image signal depending on the amount of incident light into a first pixel during a first charge accumulating period and a second image signal depending on the amount of incident light into a second pixel during a second charge accumulating period shorter than the first charge accumulating period, wherein the high dynamic range synthesizing circuit includes: a signal level adjustment unit configured to adjust a signal level of the second image signal according to a ratio between the first charge accumulating period and the second charge accumulating period; an interpolation processing unit configured to be input with the first image signal and the second image signal a signal level of which is adjusted in the signal level adjustment unit, and to generate an interpolation signal; a blur detection unit configured to detect the amount of blur generated in an object image by use of the first image signal and the second image signal a signal level of which is adjusted in the signal level adjustment unit; and a mix processing unit configured to apply a weight of the second image signal depending on the amount of blur to the interpolation signal by processing of mixing the second image signal into the interpolation signal, and the interpolation processing unit generates the interpolation signal by interpolation processing using the second image signals from the second pixels as peripheral pixels positioned around the first pixel as a target pixel for the first pixel as the target pixel, and generates the interpolation signal by interpolation processing using the first image signals from the first pixels as peripheral pixels positioned around the second pixel as a target pixel for the second pixel as the target pixel.
