摘要:
A power focus device in a camera has a manually rotatively operated focus ring, a lens driving drive source for driving a focusing lens, and a pulse generating device operatively associated with the rotation of the focus ring to generate a pulse signal conforming to the amount of rotation of the focus ring. A focus ring rotation direction detecting device detects the direction of rotation of the focus ring from the pulse signal, a focus ring rotation amount detecting device detects the amount of rotation of the focus ring from the pulse signal, and a drive direction setting device sets the direction of drive of the lens driving drive source on the basis of the result of the detection in the focus ring rotation direction detecting device. A drive amount setting device memorizes the result of the detection in the focus ring rotation amount detecting device and sets the memorized value as the amount of drive of the lens driving drive source. A drive source control device control the lens driving drive source in accordance with the direction of drive set in the drive direction setting device and the amount of drive set in the drive amount setting device. A reversing device immediately reverses the lens driving drive source, changes the setting in the drive direction setting device, returns the drive amount setting device to its initial state, and immediately reverses the lens driving drive source when the focus ring has been rotatively operated in a direction to drive the lens driving drive source in a second direction when the lens driving drive source is being driven in a first direction.

In a system for setting the aperture in a camera for flash photography, a minimum aperture is computed in response to parameters such as distance to an object, stroboscopic guide number and film sensitivity. In one embodiment, a predetermined aperture value is preestablished in the system and the computed minimum aperture is compared therewith. Where the computed minimum aperture is below such predetermined aperture value, such computed minimum aperture is used in flash photography. On the other hand, when the computed minimum aperture is above such predetermined aperture value, an aperture larger than the predetermined minimum aperture value is used in flash photography. Other embodiments for flash aperture setting are also set forth.
摘要:
The present invention relates to a photographic information setting device having a switch arranged to turn on and off and generate digital data when a stepwise operating member changes its position, wherein the turning on and off of the switch is detected with the help of current supply to the switch to renew the digital data until a desired value of any exposure factor is preset. In the present invention, when the aforesaid stepwise operating member lies in any of click-stopped positions, the current supply to the switch is cut off to prevent wasteful consumption of electrical energy. The number of times of turning on and off of the switch is once stored in a counter, and, upon detection of turning on and off of the switch, a computer reads out the content of the counter so that the renewed digital data are formed in the interior of the computer.

In an image pickup apparatus comprising an optical finder for optically displaying an object image, an image pickup device for receiving the object image and converting it into an image signal for photographing, an electronic finder for displaying the object image received by the image pickup device on the basis of the image signal converted by the image pickup device, a focal plane shutter for shielding the image pickup device from light, and a beam guide device for guiding a beam from the object to the optical finder and the image pickup device, and a control method and a control program applied to the image pickup apparatus, the beam from the object guided by the beam guide device is changed over from the optical finder to the image pickup device and the focal plane shutter is rendered into its opened state so that before photographing, the image pickup device can receive the object image displayed by the electronic finder.
摘要:
Improvement of printing speed is set out in an image processing apparatus, which is connected communicably with a printing apparatus, for transferring a recorded image to the printing apparatus and having the printing apparatus print the image. To achieve this object, the present invention has the following configuration. Namely, the invention provides an image processing method of an image capturing apparatus, communicably connected with a printing apparatus which prints transmitted image data. The image processing method comprises: a receiving step (step S101, S104) of receiving information regarding a printing condition of the printing apparatus for printing the transmitted image data; a processing step (step S103, S106) of processing image data to be transmitted to the printing apparatus based on the information regarding the printing condition received in the receiving step; and a transmitting step (step S108) of transmitting the image data processed in the processing step to the printing apparatus.
摘要:
In a camera system arranged to communicate data between a camera and an accessory mounted on the camera in synchronism with a clock signal, the lens communicates data to the camera by a first communication method (an open drain method), and, if it is determined as a result of the data communication that the lens mounted on the camera is a lens suited for high-speed communication, the first communication method is switched to a second communication method suited for high-speed communication, so that communication can be performed at a high speed.

A camera with an auto-focus device and having a first mode for causing the auto-focus device to perform focusing upon operation of a second operating member independently of a release operation member and a second mode for causing the auto-focus device to perform focusing upon operation of the release operation member and interrupting focusing of the auto-focus device upon operation of the second operation member.
摘要:
An information setting device for a camera comprises a plurality of manual operation switches for setting varied kinds of information. Among these switches, when a plurality of switches are simultaneously operated, there obtains a specific setting mode for setting information of a kind different from information of other kinds to be set by individually operating these switches. In the event of thus selecting the specific setting mode, this mode remains unchanged even when at least one of the simultaneously operated switches becomes inoperative.
