    摘要: A differential/absolute value image is derived by calculating an absolute value of each pixel in an image produced by subtracting a background image from an input image. A mean value and a variance of a pixel in the differential/absolute value image are calculated from the levels of pixels included in a small region on the differential/absolute value image which has the pixel located at the center thereof. The calculated mean value and variance of the pixel are used to distinguish whether the pixel is a pixel included in a moving object existing region, a background region, or an input image sudden change region. A method of updating the background image is changed in accordance with whether the pixel is a pixel included in the moving object existing region, the background region, or the input image sudden change region.

    摘要: An image capture and transmission system includes first and second imaging devices. A timing signal generator produces a timing signal. A common drive circuit operates for driving the first and second imaging devices at equal timings determined by the timing signal. A first signal processor operates for converting an output signal of the first imaging device into first digital video data. A second signal processor operates for converting an output signal of the second imaging device into second digital video data. The first digital video data and the second digital video data are processed into a stream of packets. The packet stream is transmitted to, for example, a network.

    摘要: A communication circuit transmits the digital video signal to a transmission line and receives a clock signal and timing data transmitted through the transmission line. The timing data indicates a communication timing. A timing signal generation circuit generates timing signals from the detected clock signal to control the imager, the a/d converting circuit, the signal processing circuit, and the communication circuit. A communication control circuit detects a communication timing from the timing data, judges whether the communication timing is detected within a predetermined condition (communication error), and controls the timing signal generation circuit to stop transmitting the digital video signal when the communication timing is not detected within the predetermined condition to prevent a fail in transmitting the video data. A shutter interval of the imager is further controlled toward a constant shutter interval in response to the communication error. The video signal is stored in a memory in response to the communication error and read if the communication error eliminated. The communication error is displayed. A system control signal indicative of data transmission period is generated in response to a received cycle start packet in accordance with the obtained data rate and channel timing.

    摘要: The two-way transmissions are performed between a first bus and a usual portal of a first full-duplex 3-portal bridge and between a second bus and a usual portal of a second full-duplex 3-portal bridge, respectively. The one-way transmission of an isochronous packet and an asynchronous stream packet is performed between transmission and reception portals of the first full-duplex 3-portal bridge and reception and transmission portals of the second full-duplex 3-portal bridge. The first full-duplex 3-portal bridge and the second full-duplex 3-portal bridge perform a conversion between the asynchronous stream packet and an asynchronous packet if necessary.

    摘要: In a lead frame, L-shaped support tapes are applied to inner leads and suspension leads. Ends of the support tapes are overlapped with each other at the suspension leads to form, together, a rectangular ring shape. Since the support tapes are L-shaped, when the overlapped portions are positioned at the suspension leads, there are only two overlapped portions of the support tapes at the suspension leads. Thus, the number of overlapped portions requiring accurate alignment is reduced. Moreover, the L-shaped support tapes can be cut from the material for the support tape with higher efficiency.
