A solid state imaging device detects the period of energy variation of discharge type illumination, and sets a total exposure time to match the detected period. The total exposure time is divided into alternating valid and invalid exposure times by a division ratio to make the sum of the valid exposure times equal to an actual exposure time corresponding to an actual speed of an electronic shutter. Charges accumulated in a CMOS sensor during the valid exposure times are stored in a floating diffusion, whereas charges accumulated during the invalid exposure times are drained. At the end of the total exposure time, the charges stored during the valid exposure times are converted to an electrical signal which is output to a signal processing circuit. This device can correct variation of output signals which corresponds to the illumination energy variation when the shutter is operated for imaging under high luminance illumination.

Solid state imaging device for correcting level variations in output signals

The present invention discloses a television receiving system comprising: a smart antenna having a receiving unit that electrically switches directions of receiving television broadcasting signals and a connecting portion that is detachably connected to the receiving unit; and a television receiver couple with the receiving unit though the connecting portion and having a holding portion that holds the receiving unit detached from the connecting portion on a rear surface of the television receiver where is opposite to a front surface displaying videos.

Television receiving system

With a power supply provided for a smart antenna, whether the antenna is connected is determined according to whether the power supply is connected. When it is determined that the smart antenna is not connected, power supply to units related only to controlling of the smart antenna is stopped, whereby power saving is realized. Further, user's setting for discriminating kinds of antennas becomes unnecessary and, when a smart antenna is not connected, power supply for the same can be prevented.

Broadcast receiving apparatus

The present invention discloses a smart antenna that includes: a switch unit that switches a direction for receiving radio waves; and an outer covering unit that covers the smart antenna and is made of an insulating material.

Smart antenna

A television receiving apparatusincludes a television receiver, and a smart antennahaving directivity capable of being electrically changed so as to match radio waves to be received. A handleis provided with a mechanism holding the smart antennatherein, fixed to the television receiverand capable of changing the distance between the smart antennaand the television receiveras an antenna holding box. The antenna having directivity capable of being electrically changed so as to match with radio waves to be received is disposed so that the aesthetic appearance can be improved and the signal receiving sensitivity of the antenna can be enhanced.

A holding partfixedly holds a shaftincluded in a smart antennaon a television receiver. The smart antennais held fixedly by the holding part. The shaftof the smart antennais provided with an openingin a part thereof distant from a part thereof held by the holding part. A wiringis extended outside from the shaftthrough the openingand is connected to the television receiver

Smart antenna and antenna fixing mechanism

Disclosed is an antenna system, including: an antenna which can switch directivity thereof when receiving an analog television broadcasting signal; a switching section to switch the directivity of the antenna; a measurement section to measure radio wave quality of the analog television broadcasting signal received by the antenna by analyzing the analog television broadcasting signal when the directivity of the antenna is switched by the switching section; a storage section to store data of radio wave quality in different directions measured by the measurement section for each channel; and a control section to control the switching section to switch the directivity of the antenna to one direction having a highest radio wave quality among the different directions corresponding to a desired channel when the desired channel is designated.

Antenna system

Each of three light receiving sections has a P-type well having a P-type layer and an N-type layer formed therein. The P-type layer is diffused from substrate surface to depth d. A PN junction forming portion of the N-type layer is diffused from depth dto depth dwhich is greater than depth dso as to form, with the P-type well, a PN junction of a photodiode at depth d. Depths das well as depths dof the three light receiving sections are different from each other. The N-type layer has a charge output portion which is diffused from the PN junction to the substrate surface, and which is coupled by circuit coupling to a MOS transistor for reading out charge. This allows each light receiving section to have spectral characteristics, thereby providing a solid state imaging element and a solid state imaging device without using color filters.
