IMAGE PROCESSING DEVICE

摘要

An aspect of one embodiment, there is provided a solid state image-processing device, including a gain adjustment unit configured to adjust each of pixel data transmitted from each of the pixels as gain adjustment data corresponding to a sensitivity ratio between a sensitivity of each of the pixels and a sensitivity of the pixel with the highest sensitivity to transmit each of the pixel data and each of the gain adjustment data, an effectiveness decision unit configured to decide each pixel value being ranged in a prescribed effective range or not, an inversion decision unit configured to decide a pixel with higher sensitivity in two pixels which are an inversion state or not when the pixel data of each of the two pixels are decided to be effective by the effectiveness decision unit, a blend unit configured to blend the gain adjustment data with respect to the two pixel data to transmit blend pixel data when the inversion decision unit is in a non-inversion state, and selection unit configured to select one of the gain adjustment data and the blend pixel data to transmit the selected data as an HDR output data on a basis of a first judge result of the effectiveness decision unit and a second judge result of the inversion decision unit.

1. An image processing device, the image processing device comprising a plurality of pixel areas, each of the pixel areas comprising a plurality of pixels, each of the pixels mutually having different sensitivity with respect to an input photo amount, the image processing device comprising:
a gain adjustment unit configured to adjust each of pixel data transmitted from each of the pixels as gain adjustment data corresponding to a sensitivity ratio between a sensitivity of each of the pixels and a sensitivity of the pixel with the highest sensitivity to transmit each of the pixel data and each of the gain adjustment data; an effectiveness decision unit configured to decide each pixel value being ranged in a prescribed effective range or not; an inversion decision unit configured to decide a pixel with higher sensitivity in two pixels which are an inversion state or not when the pixel data of each of the two pixels are decided to be effective by the effectiveness decision unit; a blend unit configured to blend the gain adjustment data with respect to the two pixel data to transmit blend pixel data when the inversion decision unit is in a non-inversion state; and a selection unit configured to select one of the gain adjustment data and the blend pixel data to transmit the selected data as an HDR output data on a basis of a first judge result of the effectiveness decision unit and a second judge result of the inversion decision unit.
