    • A blur-correcting image pickup device includes, but is not limited to an image pickup optical system for picking up an image, a vibration-detecting device which detects vibrations of the image pickup device and generates an output relative to the detected vibrations, a blur-correcting device which corrects blurring of the image caused by the vibrations, a rangefinder which detects distance of the image to be picked up and generates an output relative to the detected image pickup distance, and an optical system setup device which sets up a specific image pickup condition for the image pickup optical system. The blur-correcting image pickup device further includes an arithmetic information generating device which generates a first arithmetic factor when the specific image pickup condition is set up and a second arithmetic factor corresponding to the output of the rangefinder when the specific image pickup condition is not set up by the optical system setup device and a drive control device which calculates corrective information based on the output of the vibration-detecting device and the output of the arithmetic information generating device to control the blur-correcting device based on the corrective information.

    • The control circuit selects, as the first reference cell, the first memory cell having a maximum reading current supplied by turning on the first select transistor in a state in which resistance values of the first memory cells are all increased. The control circuit selects, as the second reference cell, the second memory cell having a maximum reading current supplied by turning on the second select transistor in a state in which resistance values of the second memory cells are all increased. The first reference-current setting circuit sets, as the first reference current, a current obtained by adding a first adjusting current to the reading current of the first reference cell. The second reference-current setting circuit sets, as the second reference current, a current obtained by adding a second adjusting current to the reading current of the second reference cell.
    • 控制电路在第一存储单元的电阻值全部增加的状态下选择具有通过接通第一选择晶体管而提供的最大读取电流的第一存储单元作为第一参考单元。 控制电路在第二存储单元的电阻值全部增加的状态下选择具有通过接通第二选择晶体管而提供的最大读取电流的第二存储单元作为第二参考单元。 第一参考电流设置电路将通过将第一调整电流加到第一参考单元的读取电流而获得的电流作为第一参考电流。 第二基准电流设定电路将通过将第二调整电流加到第二参考单元的读取电流而获得的电流作为第二参考电流。
