Abstract:
An optical instrument of the present invention comprises a ring member which is arranged to be rotatable with respect to a lens barrel, and also to slide in an optical axis direction to a first position and a second position, a rotation position detection section for outputting a preset distance that has been set by a rotation operation, when the ring member is at the second position, and a control section for, when the ring member has been subjected to a slide operation between the first position and the second position, moving a photographing lens at a first speed or a second speed up to a distance corresponding to an operation position.
Abstract:
An imaging apparatus includes a control unit that sets a touch area corresponding to a periphery of an initial touch position on a touch panel as an area used for adjusting an image that is displayed at the initial touch position on the basis of a signal that is output by the touch panel disposed in connection with a display unit.
Abstract:
An imaging apparatus includes an imaging unit, a field angle change unit, and a movement detection unit. The imaging unit includes a lens that forms an image of a subject and acquires a picture image by taking the image formed by the lens. The field angle change unit changes a field angle of the picture image acquired by the imaging unit. The movement detection unit detects a movement of the imaging apparatus. The field angle change unit changes the field angle of the picture image in accordance with a moving direction of the imaging apparatus when the movement detection unit detects the movement of the imaging apparatus.
Abstract:
When an interchangeable lens in which a memory that records image data is provided is mounted to a camera main body including a display section that displays an image, a signal processing and control section of the camera main body reads in a sample image that is previously stored in the memory. The sample image serves as a model with respect to an image that can be photographed by the interchangeable lens. The sample image is displayed by the display section for a predetermined time. Thereafter, the signal processing and control section performs display control that switches the display of the display section so as to display an image in which a subject is picked up by the interchangeable lens and the image pickup section.
Abstract:
An imaging apparatus includes an imaging unit that generates image data of a subject image obtained via a lens unit, a display unit that displays an image corresponding to the image data generated by the imaging unit, an input unit that receives input for specifying an area of a portion of the image displayed by the display unit, and a display controller that controls a display mode for confirming a specified image corresponding to the area of which input is received by the input unit.
Abstract:
To enable the user of the camera to select, using a simple mechanism, one of a function for simultaneously performing photographing and electronic image pickup, and a function for performing only one of the photographing and the electronic image pickup, the camera incorporates a release button at a position which, for example, the index finger of the right hand can reach, and another button, i.e. a digital button, at a location which the thumb of the right hand can reach. 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.
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. A comparator compares the USM motor speed with the vibration speed and outputs a comparison result to an up/down terminal of the counter, thereby switching between count-up and count-down operations of the counter.
Abstract:
An imaging apparatus comprises an optical system that includes a plurality of lens groups, each lens group including one or more lenses, at least one of the lens groups being independently movable with respect to the other lens groups and including a focus lens group for focusing the subject and a lens control unit that controls movement of the plurality of lens groups to bring into focus based on a feeding position of the focus lens group.
Abstract:
An image pick-up device shoots a scene by exposing a film by way of an optical system and recording an image of the scene on the film. A shake quantity detecting unit detects a shake quantity of the image pick-up device during the exposure of the film to the scene by the device and a shake data recording unit records data representing the shake quantity on a recording medium on the film. A shake data reproducing unit reproduces the data representing the shake quantity recorded on the recording medium. A shake trace data transformation unit outputs shake transmitting functions generated on the basis of the data representing the shake quantity. A first Fourier transformation unit carries out a Fourier transformation on the shake transmitting functions. Image transformation unit transforms the image of the scene recorded on the film into digital signals. A second Fourier transformation unit carries out a Fourier transformation on the digital signal. A dividing unit carries out divisions on outputs from the first and second Fourier transformation units. An inverse Fourier transformation unit carries out an inverse Fourier transformation on an output from the dividing unit, an output from the inverse Fourier transformation unit being an image of the scene free from any trace of the shake.
