IMAGE PICKUP UNIT IMAGE PICKUP DEVICE AND IMAGE PICKUP CONTROL PROGRAM

摘要

When the amplification factor is lowered where the intensity of the incident light is strong and the amount of charge is large the signal that is read from regions of weak intensity of the incident light becomes weak. Contrariwise when the amplification factor is raised to accord with regions where the intensity of the incident light is weak the signal that is read from regions of high incident light intensity may become saturated. For this reason the dynamic range of an image pickup unit was restricted to a narrow range. Accordingly there is provided an image pickup unit comprising: an image pickup section including a first group containing one or more pixels and a second group containing one or more pixels different from the pixels constituting the first group; and a control section that outputs respective pixel signals by performing charge accumulation in the case of the first group in the period in which a single charge accumulation cycle is executed and in the case of the second group by performing charge accumulation for a number of charge accumulation cycles different from that in the case of the first group.
