According to the present invention, face parts to be compared are set by the comparison target setting section based on the number of images of a group of search target images. Then, a retrieval target image and each image of the group of search target images is compared by the set face parts. An image with a particular correlation is determined to be a similar image and retrieved from the group of images to be compared. Thereby, it is possible to perform quick retrieval based on the number of images of the group of search target images.

摘要:
Before obtaining service from an installed terminal, a mobile unit can be authenticated (subauthenticated) only by the operation of the mobile unit such as an unauthenticated digital camera, etc. using an authenticated mobile phone. A digital camera is radio-connected with an installed terminal, and the digital camera is also radio-connected with a mobile phone of a user. The installed terminal center is notified of the identification code of the mobile phone through the digital camera and the installed terminal. The installed terminal center inquires of the carrier center about the validity/invalidity of the mobile phone. Upon receipt of the notification of the validity of the mobile phone from the carrier center, the installed terminal center permits service to the installed terminal in the installed terminal.

To provide a communication terminal apparatus including a first wireless communication unit that can connect with a host computer, a second wireless communication unit that can connect with connecting equipment by wireless, an equipment information storage unit for storing image information showing an appearance of the above-described connecting equipment, a display unit for displaying the appearance of the connecting equipment, and a designating unit for establishing communication with the connecting equipment thereafter, which is designated, when the appearance of the desired connecting equipment that is displayed in the above-described display unit is designated, in which, since the above-described wireless communication unit receives and displays image information showing the appearance of the above-described connecting equipment from the host computer if the image information showing the appearance of the above-described connecting equipment is not stored in the equipment information storage unit. Hence it becomes possible for the communication terminal apparatus to receive the appearance and product names of all the connecting equipment that are connected to the communication terminal apparatus, to display them in the display unit, and to establish communication.

A digital still camera is designed so that even a beginner can acquire photographic technique. To this end, picture-taking advice conforming to the subject of photography is displayed, in a shooting mode, on the display screen of a liquid crystal display device with which the camera is provided. By viewing the displayed picture-taking advice, the user becomes aware of the essentials of photography. The user is prevented from making picture-taking errors by shooting in accordance with the picture-taking advice.

A white balance adjusting device for use in a camera which photographs a field and forms a video signal representing the field. In the white balance adjusting device, while a sequential photographing is under way, updating of the color temperature data to be used for adjusting a white balance is prohibited. Therefore, the hues of main objects in the respective frames of still images photographed by the sequential photographic operation remain unchanged, thereby maintaining the homogeneity of the main objects. Also, in the white balance adjusting device, control a device is used to provide a short response time for a quick response property in a still mode and to provide a longer response time in a movie mode when compared with the still mode. As a result, the white balance can be adjusted according to the photographic modes of the camera.
摘要:
In an electronic still camera, a mechanical shutter is opened in synchronizing with a synchronizing signal generated by a synchronizing signal generating circuit, a solid state electronic imaging device is exposed while the mechanical shutter is being opened, and a video signal outputted from the imaging device and representing an imaged subject is processed by a signal processing circuit. The synchronizing signal generating circuit starts the generation of the synchronizing signal in response to a shutter release by a shutter release button. The mechanical shutter is opened in synchronizing with a synchronizing signal which is generated after a predetermined constant time period elapses from the start of the operation of the synchronizing signal generating circuit, and is closed after time necessary for exposure elapses from the opening of the mechanical shutter.
摘要:
In an image data transfer system including an electronic still camera and equipment separably connected to the camera, the camera has an imaging device for shooting a desired subject. A signal converter converts an image signal generated by the imaging device to digital image data. A data processor executes predetermined image processing with the digital image data. A transmitting section sends the processed image data output from the data processor to the equipment. A controller controls the transmitting section in such a manner as to control a transfer rate for transferring the image data to the equipment. The equipment has a receiving section connected to the transmitting section of the camera by a data line for transferring the image data, and a control line for reporting to the camera the permission/inhibition of data transfer from the camera by using an ON/OFF control signal. The controller controls, at the time of transfer of the image data to the equipment, the transmitting section so as to send a transfer rate set command representative of a transfer rate to the equipment over the data line. In response, the receiving section reports to the camera whether or not the equipment accepts the transfer rate by varying the ON/OFF control signal in the form of pulses.

An analog/digital converting circuit necessary for recording processing is also used when exposure control is performed employing digital image data. A gamma corrector circuit 10 capable of being changed over between a gamma-correction characteristic and a linearly proportional characteristic in response to depression of a two-stage shutter release button is provided. When exposure control is carried out, changeover of the gamma-corrector circuit 10 is controlled in such a manner that the input/output characteristic of the circuit will be a linearly proportional characteristic. When exposure control is performed, a b terminal of a changeover switch 14 is connected to the A/D converting circuit 13 so that a photometric value is calculated using circuits 15, 16, and 17. When processing for recording image data is executed, changeover of the gamma-corrector circuit 10 is controlled is such a manner that the output signal thereof takes on the value of the input signal raised to the 0.45 power, and an a terminal of the changeover switch 14 connected to the A/D conversion circuit 13. The image data is recorded on a memory card 40 using circuits 31, 32, 33 and 34.
摘要:
A recording/playback apparatus is provided with a plurality of controllers (inclusive of CPU's) which, by communicating with one another, share control of each of the components of the recording/playback apparatus or of the entire apparatus. Communication among the controllers is performed in the second half of one period of a signal related to the rotational reference phase of a rotating recording medium. This makes it possible for control requiring high precision to be performed in the first half of the aforementional period without being affected by high-priority interrupts which accompany communication control. Further, in order that the aforementioned communication may be carried out in the second half of the above mentioned period, message editing is performed in the first half of the same period. This enables prompt communication processing during the short time in the second half of the period without an unnecessary waste of time.
