Imaging device

摘要

An imaging device includes a solid-state imaging device configured to include a plurality of pixels, the solid-state imaging device outputting subject data according to a pixel signal output by the pixel of an image region on which subject light is incident and optical black (OB) data according to the pixel signal output by the pixel of a constantly shielded OB region of a plurality of columns or rows located on an end of the image region as image data, and an imaging processing unit configured to output pre-processed image data obtained by performing black level correction on partial subject data included in the image data using the same OB data included in the image data output by the solid-state imaging device.

1. An imaging device comprising:
a solid-state imaging device configured to include a plurality of pixels, the solid-state imaging device outputting subject data according to a pixel signal output by the pixel of an image region on which subject light is incident and optical black (OB) data according to the pixel signal output by the pixel of a constantly shielded OB region of a plurality of columns or rows located on at least an end of the image region as image data; and an imaging processing unit configured to output pre-processed image data obtained by performing black level correction on partial subject data included in the image data using the same OB data included in the image data output by the solid-state imaging device; a data extracting unit configured to extract the OB data common in the subject data included in the image data output by the solid-state imaging device as extraction OB data and output each of the subject data and the extraction OB data included in the image data; a pre-processing unit configured to include a line memory configured to hold an amount of subject data which is less than a data amount of the subject data of a first direction in the image region and output the pre-processed image data obtained by performing the black level correction based on the extraction OB data for the subject data output from the data extracting unit and held in the line memory;and
a storage unit configured to store at least the pre-processed image data, wherein the data extracting unit divides the image region within the range of the data amount of the subject data capable of being held by the line memory, outputs the subject data and the extraction OB data of a first image region on which the pre-processing unit is able to perform the black level correction to the pre-processing unit, and outputs the subject data and the extraction OB data of a second image region on which the pre-processing unit has not performed the black level correction and which is different from the first image region as original image data, wherein the pre-processing unit outputs the pre-processed image data obtained by performing the black level correction based on the extraction OB data for the subject data of the first image region, and wherein the imaging processing unit further includes:
a first data transfer unit configured to transfer the pre-processed image data to the storage unit; anda second data transfer unit configured to transfer the original image data to the storage unit.
