A linear image sensor device with at least two lines including linear sensors 10, 20, which device is capable of showing a wide dynamic range. In the linear image sensor device, one linear sensor 10 is made to have a high sensitivity, while the other linear sensor 20 is made to have a low sensitivity. The linear sensors are respectively equipped with readout gates 13, 23 for reading out charges from sensor arrays 12, 22 comprising a number of pixels and CCD analog shift registers 14, 24 for transferring the charges read out. In the other linear sensor 20, analog memories 29a, 29b are provided between the readout gate 23 and the CCD analog shift register 24. Owing to the provision of the analog memories 29a, 29b, the signal outputs OUT1, OUT2 simultaneously occur, which can eliminate a problem coming from the difference in position between the lines.

A method and an apparatus for multi-window display with enhanced window manipulation facilities. In the apparatus, window images to be displayed in multi-window display are stored in a bit map memory. Various image processing operations are performed on the window images stored in the bit map memory, by regarding the window images as graphic images. Appropriate sections of processed window images are transferred to a frame buffer by using a bit block transfer device, and the image in the frame buffer is displayed on a display device.

The patient monitoring system includes a patient-data-acquiring section and a monitor section. The patient data-acquiring section includes a data-inputting device for inputting at least one of two data items, the first data item representing a patient image, and the second data item representing the physical conditions of the patient, a detecting circuit for detecting whether or not it is necessary to examine the patient's image on the basis of the data items input by the data-inputting device, a message-sending device for sending a message to the patient asking whether or not the patient agrees to be examined when the detecting circuit detects that it is necessary to examine the subject's image, an agreement-recognizing circuit for recognizing the patients's agreement to being examined, and a data-transmitting circuit for transmitting the first data item to a monitor room when the agreement-recognizing means recognizes the patient's agreement. The monitor section includes a display for displaying the patients's image represented by the first data item transmitted by the data-transmitting circuit.
摘要:
Two-dimensional images of a three-dimensional body photographed by two video cameras are parallactically compensated prior performing the detection of the corresponding point necessary to recognize the body. Namely, the parallax between both cameras for the object distance measured by a range finder is calculated by a parallax calculator, and one image is electrically shifted by an image shifting circuit by only the number of pixels in accordance with the parallax value, thereby performing the parallax compensation of the images. In a calculation processing unit, the correlation values for the corresponding points between both images are calculated, and the distance images of the body are produced on the basis of these correlation values.

A MOS transistor comprising channel stoppers formed of a first polysilicon layer to determine a channel width, and a gate electrode formed of a second polysilicon layer, wherein a bias voltage is applied to the channel stoppers. In a charge detector having a source follower circuit with a drive MOS transistor and a load MOS transistor for converting a transferred signal charge into a signal voltage, the MOS transistor of the invention is used as the drive transistor, and its source output voltage is fed back as a bias voltage to the channel stoppers, thereby minimizing both the DC bias variation in the output voltage of the source follower circuit and the nonuniformity in the conversion efficiency.
