In an CCD image sensor, when an image of a partial area is used, a frame rate is enhanced. Horizontal transfer of signal charges of an i-th line read out to a horizontal transfer portion is stopped at the time point when all or a part of a tail portionsubsequent to an extraction target portion. Under this state, the signal charges of an (i+1)-th line are transferred to the horizontal transfer portion. Thereafter, the horizontal transfer is started. Through this operation, unnecessary signal charges of the tail portionof the i-th line and unnecessary signal charges of a head portionof an (i+1)-th line are combined. By partially overlapping adjacent lines with each other, the cycle number of horizontal transfer clocks required for the horizontal transfer per line can be reduced as compared with a normal operation, thereby enhancing a frame rate.

A signal processing apparatus including a clamp pulse generation circuit for generating a clamp pulse in synchronization with an image signal, a clamp circuit for clamping a signal of a black reference value in response to the clamp pulse, and a defect detection circuit for detecting a defective pixel included in an optical black area, wherein the clamp pulse generation circuit cancels a rise of the clamp pulse when a position of the defective pixel detected by the defect detecting circuit and a position of a rise state of the clamp pulse overlap with each other.

Signal processing apparatus

A photoelectric converter device comprises a semiconductor substrate including a photoelectric converter element formed on its surface, a visible light filter arranged to at least partially cover the surface of the semiconductor substrate, and a support member attached to the surface of the semiconductor substrate. The photoelectric converter device further comprises, in an internal portion, a resin layer which absorbs infrared light. With this arrangement, undesirable influences of infrared light can be reduced.

Photoelectric converter device and manufacturing method thereof

A semiconductor integrated device that resists breakage of an internal wire. An epoxy resin covers a lower surface and side surface of a semiconductor chip. An internal pad connecting an external wire and an internal wire are formed on a silicon oxide film. The internal pad is wider than the internal wire. A portion at which the internal pad and the internal wire are connected to each other is located above the semiconductor chip. The internal pad disperses stress resulting from changes in the volume of the epoxy resin caused by temperature changes. Accordingly, stress does not concentrate in the internal wire.

Chip size package with stress relieving internal terminal

A digital recording/reproducing system includes a set top box. The STB receives a digital television broadcast signal and transmits a scrambled data stream from a stream selector via an interface to a digital recording/reproducing apparatus. In the data recording/reproducing apparatus, a scramble key is acquired depending on a billing request for data recording. To AS-MO disc are recorded a contents key converted from a disc unique ID using a descramble key as well as the data stream. In accordance with a user's approval for the billing, an account table is created which is registered in an IC card and transmitted via a MODEM and telephone line.

Digital recording/reproducing system

A magneto-optical record medium and a reproducing apparatus for the same allow data reproduction having good characteristics by a simple structure. The magneto-optical record medium includes a plurality of first grooves ( ) each having sidewalls, at least one of which is wobbled in accordance with address information; an address mark ( ) formed by changing a width of a land located between second grooves connected to the first grooves; and third grooves wobbled cyclically, formed in a data portion magnetically storing data and connected to the second grooves. The reproducing apparatus reproduces the data from the magneto-optical record medium.

Record medium and reproducing apparatus of the same for detecting an offset correction

An information recording and reproduction apparatus for a magneto-optical medium includes a synchronizing signal generation circuit for generating a synchronizing signal to provide a pulsed laser beam at the time of reproduction according to an internal clock obtained from a reproduction signal. The laser beam is driven on/off according to the synchronizing signal at the time of reproduction to have the laser spot on the signal plane prevented from being enlarged, so that the reproducible domain is smaller than the domain of when a laser beam is continuously emitted. In reproduction, an optical superresolution method is applied simultaneous to provision of a pulsed laser beam to allow reproduction of higher density. An external synchronizing signal generation circuit for generating an external synchronizing signal according to a wobble on a surface of a recording medium can be used instead of a synchronizing signal generation circuit according to an internal clock.

Information recording and reproduction apparatus carrying out recording and reproduction of information using laser beam

A meandering groove is formed in a digital disk (,) with a wobble signal that is wobbled to reproduce a clock signal. The wobble signal is read out by an optical head (,). An address detection circuit (,) detects an address signal that is multiplexed with the wobble signal. A PLL oscillation circuit (,) provides a clock signal in synchronization with the wobble signal. Data is modulated by a modulation circuit (,) according to the clock signal and a timing signal based on the address signal, and recorded on the digital disk (,). In reproduction, a RF signal in the wobble signal is converted into a digital signal by an A/D converter (,). The signal is demodulated by a demodulation circuit (,) for data output.

Digital disk recording and reproduction apparatus

Information recording and reproduction apparatus using a pulsed laser light

An optical recording medium in which any of a land (,) and a groove (,) is scanned using a laser beam, the address information of data recorded or to be recorded in the land or groove is available, the address information of the groove (,) is recorded in a first address information region (,) in an address region (,) on a sidewall of the groove as a wobble (,) and the address information of the land (,) is recorded in a second address information region (,) in the address region (,) on a sidewall of the land as a wobble (,).

A system for transmitting image data on a telephone network or equivalent, which typically includes video or visual telephones as apparatus of sending part and receiving part. In the video telephone of sending part, when an image data sending key is operated, a DTMF signal generator included in a modem is started to operated and a specified DTMF signal, for example, DTMF-A signal or DTMF-B signal is sent as a signal DTMF-DTA to a telephone circuit through a network control unit for approximate 300 milliseconds. Succeedingly, in spite of presence or absence of a responsive signal from the video telephone of receiving part, a non-signal state is formed for approximate 75 milliseconds, immediately thereafter, the image data is sent from the video telephone of sending part at a transmission speed of 4,800 bps or 2,400 bps. In the video telephone of receiving part, when the signal DTMF-DTA, that is, the above described DTMF-A signal or DTMF-B signal is continuously received for approximate 250 milliseconds, a modem thereof is started at 4,800 bps or 2,400 bps, and the image data being sent from the video telephone of sending part is received.
