摘要:
A vibration wave motor control apparatus which has a simplified construction and is reduced in cost. In a photographic apparatus including a lens, a lens position controller controls the position of the lens using a vibration wave motor driven by a drive voltage of a set frequency, and a drive-frequency controller controls the set frequency. The drive-frequency controller determines an estimated frequency based on a change in the position of a movable unit of the vibration wave motor determined from data inputted from an encoder, and based on the estimated frequency, calculates an updated value of the set frequency and inputs the same to the lens position controller.

A fuel cartridge includes a fuel tank which stores fuel to be supplied to a fuel cell of a main device, and a storage unit which stores information on type of fuel, remaining amount of fuel in the fuel tank, and number of times the fuel tank has been used. The fuel cartridge is formed separate from the fuel cell.

An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a first speed and a second recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a second speed different from the first speed, is arranged to reproduce the video data, in the case of a slow reproduction mode, while transporting the tape-shaped recording medium at a predetermined speed irrespective of the recording mode of the video data.
摘要:
An information signal reproducing apparatus for reproducing information signals from a recording medium in which a pilot signal component having a predetermined frequency is superimposed on the information signals at every other track of a plurality of parallel tracks. A tracking error signal is formed from pilot signal crosstalk from tracks in which the pilot signal component is not superimposed. The tracking error signal is modified using the signal on which the pilot signal component is superimposed. To facilitate such a modification, no pilot signal is superimposed in a second area of the track in which the pilot signal component is superimposed in a first area thereof, and the pilot signal is superimposed in the second area of the track in which no pilot signal component is superimposed in the first area thereof.

In a record/playback apparatus, if playback of image data is stopped, recording information relating to a stop point at which the playback of the image data is stopped and generating image data playback control information that specifies a playback resume point based on the stop point at which the playback of the image data is stopped. When the image data is recorded onto another recording medium, the playback control information is recorded together with the image data as resume information, thereby providing a user-friendly resume playback function.
摘要:
An information processing apparatus and method for processing an input image by comparing a stored background image with the input image to obtain a difference, collating a change in the difference and time of the change with conditions for the occurrence of a periodic event and information as to the time of occurrence of the periodic event, which are previously stored in a storage unit, to determine whether the change in state of the input image is the periodic or a non-periodic movement of an object, and selecting, according to a result of the determination, any one of operations according to the periodic or the non-periodic movement of an object.

An image-pickup apparatus is disclosed which is capable of realizing a focus-effect function in a constant time without being influenced by contrast of an object or the position of a focus lens. The apparatus includes a signal generator which generates a focus evaluation signal, a detector which detects information corresponding to an object distance, and a controller which performs focus lens control on the basis of the focus evaluation signal and focus lens control on the basis of information corresponding to the object distance. The controller determines a direction and a velocity in which the focus lens is moved toward an in-focus position on the basis of the information corresponding to the object distance in the focus lens control according to the focus-effect function. The controller performs the focus lens control on the basis of the focus evaluation signal after the focus lens is moved in the determined direction.
