The camera is operated in accordance with a predetermined control program so that the above-described operations can be selectively executed by appropriately operating the release button and the digital button. In other words, the invention provides a camera that permits the user to easily select, using only one hand, only electronic image pickup, only film exposure, or simultaneous execution of both the operations.

Abstract: A camera with shake compensation which detects camera shake and cancels image blur on a film exposing aperture due to the shake. The camera is capable of conserving battery power by automatically entering a power saving stand-by mode in which some of the functional blocks of the camera are powered down. The camera includes a selectable shake compensation mode, camera shake detecting circuits, and a control circuit that does not allow the shake detecting circuits from entering stand-by mode whenever the shake compensation mode is active. As a result, the camera is ready to perform shake compensation immediately upon exiting stand-by mode.

A discriminator discriminates at least one of an operational status of a camera and history data of shake correction driving. An initial position of shake correction for initialization of the shake correcting section is set based on the detection result from the relative position detector. A driving mode of driving of the shake correcting section to the set initial position is changed based on a discrimination result from the discriminator.

Abstract: A camera which reduces camera shake by adjusting the shutter timing is characterized in that it has a mode for displaying a camera shake amount to allow a photographer to recognize a camera shake. A shutter timing determining section permits shutter release at a timing at which the camera shake amount becomes a predetermined amount or less during a shutter release operation on the basis of the camera shake amount detected by a camera shake detecting section. When a camera shake learning mode is set through an input section, a camera shake amount is converted into a display amount by a display data converting section through a camera shake mode selecting section. This display amount is displayed on a display section in real time while a shutter release button is depressed.

Abstract: An acceleration of a vibration generated in an optical system of, e.g., a camera is detected by a subtracter from output signals of acceleration sensors. An absolute value circuit calculates an absolute value of an acceleration signal from the subtracter. A voltage-controlled oscillator (VCO) generates clocks having a frequency corresponding to a magnitude of the absolute value from the absolute value circuit. The clocks from the VCO are input to a clock terminal of an up/down counter. An ultrasonic motor (USM) drives the optical system in a direction to cancel the vibration. The USM is driven and controlled by a USM control circuit so as to be rotated at a speed corresponding to a count value of the counter. A motor speed detector detects a USM motor speed from output signals of a rotary encoder. An integrator integrates the acceleration signal from the subtracter to obtain a vibration speed.

Abstract: An auto-focus camera detects a focal offset, which is converted into a lens drive value utilizing data stored in lens ROM or the like which is specific to a particular taking lens. When the specific data represents a lens drive value which is stored in a table form in a manner corresponding to the focal offset, a lens drive value corresponding to the detected focal offset is selected, and is used to drive the focus lens. When the specific data is not dependent on the focal offset, a lens drive value is calculated utilizing the focal offset and the specific data, and is used to drive the focus lens.
