Imaging unit, imaging apparatus, and computer readable medium storing thereon an imaging control program

Abstract

When the amplification ratio is low and strong incident light causes a large charge, the signal retrieved from regions where the incident light is weak is also weak, but when the amplification ratio is high in regions where the incident light is weak, the signal retrieved from regions where the incident light is strong becomes saturated. Therefore, the dynamic range of the imaging unit is narrow. Provided is an imaging unit comprising an imaging section that includes a first group having one or more pixels and a second group having one or more pixels different from those of the first group; and a control section that, while a single charge accumulation is performed in the first group, causes pixel signals to be output by performing charge accumulation in the second group a number of times differing from a number of times charge accumulation is performed in the first group.

What is claimed is: 
     
         1 . An imaging sensor comprising:
 a first semiconductor substrate having a plurality of pixels; and   a second semiconductor substrate having a driving section that outputs a first control signal for controlling at least a first pixel among the plurality of pixels, and a second control signal for controlling at least a second pixel among the plurality of pixels.
