摘要： In a focal plane shutter of the kind having a plurality of divided blades pivotally arranged to be turnable on driving arms in an overlapped state, the weight of the blades is reduced by making them from very thin material; the blades are reinforced with embossed protrusions which are formed in the longitudinal direction of the blades for the purpose of preventing them from flexing and being damaged during their travel. Each of the embossed protrusions is within the difference in stepped height between the surfaces of the blades and the heads of blade carrying studs disposed on the driving arms. Therefore, the shutter can be smoothly operated without increasing the thickness of the blades as a whole.

摘要： When a first display device displays image data, a display control apparatus reserves a memory space having the first horizontal pixel number in the storage unit, and sets the frequency of a clock signal supplied to the display control unit to a first frequency. When a second display device displays image data, a display control apparatus reserves a space of the second horizontal pixel number, which is higher than the first horizontal pixel number, and sets the frequency of a clock signal supplied to the display control unit to a second frequency which is higher than the first frequency.
