Abstract: Disclosed herein is an image recording device for recording a plurality of images on a single recording medium.

Abstract: An image recording device for recording one or more images on a single recording medium includes a frame memory having a plurality of frame memory areas, the number of which is at least one greater than the number of images arranged along a main scanning direction on a recording medium. Upon the completion of storage of image data in the a number of frame memory areas equal to the number of images arranged along the main scanning direction, a storage completion signal is produced. A recording unit is energized to automatically record the images on the recording medium in response to the storage completion signal, and new image data are stored in another frame memory area.

Abstract: A thermal head in a printer, which has an array of heating elements along a main scanning direction, the heating elements being drivable by a pulse signal is driven for two-dimensionally scanning a heat-sensitive medium which is moved in an auxiliary scanning direction normal to the main scanning direction, thereby recording image information on the heat-sensitive medium. The temperature of the thermal head is detected, and a change in the detected temperature is calculated per predetermined time. Thereafter, the pulse duration of a pulse supplied to the heating elements is gradually increased or reduced. Depending on the calculated change in the temperature, per each of main scanning lines within a predetermined length in the auxiliary scanning direction.

Abstract: A video signal processing device is incorporated in an image output device such as a thermal printer which is connected to an analog video signal source such as a computerized medical diagnostic imaging system, e.g., a CT scanner. The video signal processing device has a memory which stores data for determining the total number of horizontal pixels along a single horizontal line in a frame based on the number of frames to be displayed on a display unit or recorded on a recording medium, and the aspect ratio of the frames, and data for determining the frequency of the sampling pulses supplied to an A/D converter based on the total number of horizontal pixels and the number of scanning lines of the analog video signal. Based on the data stored in the memory, a processor supplies sampling pulses to the A/D converter depending on input and output conditions which are entered through a control panel by the operator.
