摘要:
An information signal processing apparatus for processing an information signal is arranged to temporarily store information data inputted thereinto and move, after a predetermined amount of information data is stored, a moving element of a recording medium into which the information data is to be recorded, so that it is possible to stably execute continuous recording of the information signal by means of a simple arrangement with a small power consumption.

A data erasing device erasing designated data includes designating circuitry for designating one of two groups in a storage medium. The two groups comprise a first group including an upper block preceding a designated block, and a second group including a lower block following the designated block. Erasing circuitry is provided for erasing data recorded in blocks which are included in the designated group. Preferably, a designated block is one track in a recording disk, and the tracks above and/or below the designated track are erased.

A display device having a plurality of display modes may be used with a recording apparatus which records received image information on a recording medium. An information display is provided for displaying data. Exposure correction circuitry corrects an exposure characteristic of the received image and provides exposure correction information in response to a setting operation. Circuitry is provided for generating an identification code to be recorded on the recording medium together with the image information. Control circuitry is provided having a first display mode for causing the display to display the correction information from the exposure correction circuitry when the exposure correction information has been set, and a second display mode for causing the display to display the identification code generated by the generating circuitry instead of the correction information when the exposure correction information has not been set.
摘要:
An electronic camera for recording an image of an object on a recording medium using a head and an imaging device. The camera has an electronic shutter pulse generation circuit for electronically reading out a signal stored in the imaging device within a short time. The camera also has a head moving mechanism for moving the head relative to the medium, where the time required for moving the head to the next tract after recording is arranged to be within a period equal to an n multiple (n is an integer) of a vertical synchronizing period of a video synchronizing signal.
摘要:
A recording apparatus comprises a recording head arranged to record signals on a recording medium; a motor for shifting a relative position between the recording medium and the recording head; and a control circuit arranged to apply electric energy to the motor in starting the motor either in a first mode in which the electric energy is limited to a first value or in a second mode in which the electric energy is limited to a second value which is lower than the first value. Also disclosed is a motor control circuit which is highly suited to the recording apparatus. Detecting apparatus is also included to detect whether the power source is an A.C. adapter or a battery.
摘要:
A speed control device for controlling the speed of an electric motor for rotating a recording medium by a feedback control system including a proportion term proportional to information on a deviation of the speed of the motor from a speed set value and an integration term obtained by integrating the information of the deviation with respect to time. The value of the difference between a stationary term obtained when the head is loaded on the recording medium and a stationary term obtained when the head is unloaded is previously memorized about each of head load positions. Depending on the head load position, the memorized corresponding stationary term is supplied to the feedback control system, whereby the speed of the motor is maintained constant despite a change in the load.
摘要:
An image sensing apparatus wherein a memory is arranged to store the whole of data representing the positions of all defects existing in an image sensor. A cyclic register is arranged to received from the memory and temporarily store the data representing the positions of a plurality of defects. A comparator compares the scanning position of the image sensor with the defect position data stored by the register, and a correction circuit corrects the output of the image sensor according to the output of the comparator.

Disclosed is a graphics display device comprising a graphics control board provided between a computer for outputting an output command of a picture image (hereinafter referred to as an image-depiction command) to be displayed on a display device such as a cathode ray tube (CRT) and said display device to process the image-depiction command from the computer by signal conversion processing and to control a display output when the display device displays a picture image, the graphics control board being divided into two boards of a signal conversion board provided within a housing case in which the computer is installed to process the image-depiction command from the computer by signal conversion processing and a display output board for controlling a supply of an output required to display the picture image by the display device on the basis of the image-depiction command.
摘要:
An image pickup device in which electrical signals, representing an optical image from an image pickup element, are integrated during a first period and then the integrating operation is suspended for a prescribed time in which the output of the integrating circuit is read in a computer circuit. Thereby an otherwise necessary sample-and-hold circuit can be removed.
