An automatic focus adjustment method for transmitting, from a camera main body side to a lens side, a driving amount of a focus operation member configured to drive a lens, the automatic focus adjustment method includes, when a driving amount according to defocus of an object is transmitted, transmitting a driving permissible time of the focus operation member according to a control method of automatic focus adjustment as well. On the camera main body side, the driving permissible time is acquired according to the set control method of the automatic focus adjustment. On the lens side, drive control of the focus operation member is switched so that a driving time of the focus operation member satisfies the driving permissible time.

According to one embodiment, a high-frequency, broadband amplifier circuit includes two drive elements, a matching circuit, a Balun circuit, a power supply, and a power supply circuit. The matching circuit includes two pattern circuits. The pattern circuits convey, in differential mode, the high-frequency signals supplied from the two drive elements. The Balun circuit converts the high-frequency signal to a single-end mode signal. The power supply circuit is connected one of the pattern circuits, and supplies at least the output of the power supply to the other pattern circuit.

An image capturing apparatus for capturing the image of a subject includes: a lock/unlock unit adapted to lock and unlock operation of the image capturing apparatus; a registration unit adapted to register a main item and a sub-item that have been selected by a user, wherein the main item is a main setting item among operation items of the image capturing apparatus and the sub-item is a setting item in a layer lower than that of the main item; and a control unit adapted to limit operation solely to a release operation of the image capturing apparatus and to the main item and sub-item, which have been registered by the registration unit, in a case where operation of the image capturing apparatus has been locked by the lock/unlock unit.

Image capturing apparatus, method of controlling same and program therefor

An imaging apparatus includes an image data generating unit, a verification data generating unit, a first slot, a second slot, a first interface and a second interface. The image data generating unit generates image data. The verification data generating unit generates first verification data used to detect whether the image data is changed. A recording medium is inserted to the first slot. An image verification apparatus is inserted to the second slot. The first interface unit stores a first image file in the recording medium, the first image file including the image data and the first verification data. The second interface unit that transfers the first image file to the image verification apparatus. The image verification apparatus is capable of detecting, using the image data and the first verification data, whether the image data is changed.

A method for processing images comprises the steps of performing the reception of data through the net work, inputting image data obtainable in accordance with the designated input mode, managing the storage of the data received in the receiving step and the image data inputted in the input step to the memory, and intervening between the operations of the reception step and the input step in accordance with the storage management in the controlling step. With the method thus structured, the compression ratio of the input image is heightened by changing the current photographing mode if the added value of the estimated reception data through communicating means and the data side of photographed image predetermined by the current photographing mode should exceed the remainders of memory in the storage, hence making it possible to implement the compatibility of immediacy between the image input and the communication by dealing with any sudden reception during photographing.

There is disclosed an image processing system capable of effectively utilizing a large-sized display unit by expanding the image signals to be displayed.

Image processing system

There is disclosed an image processing system composed of a network of plural stations, in which the transmitted image signals can be monitored on real time basis, always utilizing the full image display area and without lack in the displayed image, by suitably converting the image signals.

An image processing system has an original reader or an image file for generating an image signal, a soft display, a high-speed printer, a small printer, a work station with a CPU, and a switching device. An image can always be displayed or printed at the center of a display surface or of a recording medium irrespective of a difference in the image and the display surface or recording medium.

An image processing system transmits image information in the form of electrical signals among plural stations for processing. A switching unit is provided to supply plural sets of signals to the plural stations in a parallel manner, thus achieving efficient signal transmission.

There is disclosed an image forming apparatus capable of image formation under optimum image forming conditions in response to the detected image density. The image forming apparatus has image forming unit for forming an image corresponding to an original on a recording material, detector for detecting the image density of the original, and controller for controlling the operable condition of said image forming unit to regulate the copy density in response to the image density detected by said detector said controller includes memory storing control data for the operable condition of said image forming unit in response to the detected image density, and is adapted to make an access to said memory in response to the detection signal of said detector and to control said operable condition according to control data obtained by said access.

Image forming apparatus

An information retrieval system for retrieving desired information from information recorded in a record medium is disclosed. The information on the record medium is classified into at least two groups and a first mark is added to the lower class information and a second mark is added to the higher class information. The marks are detected by mark detection means and the feed of the record medium is controlled in accordance with the output of the mark detection means. When there is an error in the retrieval or in the input, the error is detected and the feed of the record medium is stopped.
