The optical device of the present invention includes an optical element; a first holding member that holds the optical element; and a second holding member that holds the first holding member via a plurality of connections, and has a linear expansion coefficient different from that of each one of the optical element and the first holding member. When the plurality of connections are displaced upon receiving a force depending on the difference of the linear expansion coefficients between the first holding member and the second holding member, the first holding member causes the connection to the optical element to be displaced in a predetermined direction different from the displacement. The predetermined direction is the opposite direction of a force received by the connection between the optical element and the first holding member, depending on the difference of the linear expansion coefficients between the optical element and the second holding member.

When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive (S7), performs metering operation using preliminary flashing (S8) and calculates an appropriate amount of flashing on the basis of the metering operation (S9). Next, the imaging apparatus judges whether or not it is possible to flash three times consecutively with the calculated amount of flashing (S10). If it is judged that it is not possible to flash three times consecutively with the calculated amount of flashing (NO in S10), the imaging apparatus limits the amount of flashing to the largest amount of flashing within the range of amounts of flashing with which flashing of strobe light three times consecutively is possible (S11), and performs strobe consecutive shooting with the limited amount of flashing (S13 to S17).

The present invention provides a transreflective type liquid crystal display unit, which can reduce power consumption of backlight and displays high-quality image. The liquid crystal display unit of the present invention comprises a first reflective electrode 105, which is installed on inner surface of one substrate 100 and has reflective surfaces on front and rear surfaces and is designed to have reflective lens structure with a convex portion to face to a counter electrode and has an opening 153 at the vertex of said convex portion. Further, the liquid crystal display unit has a second reflective film 104 having reflective surface on the surface facing to the first reflective electrode 105 between the first reflective electrode 105 and said one substrate 100 and under the opening 153 of the first reflective electrode 105. A light entering from the direction of said one substrate 100 is reflected by the rear surface of the first reflective electrode 105 and by the front surface of the second reflective film 104, and the light is converged to the opening 153 of the first reflective electrode 105 and is allowed to pass toward the other substrate 200.
