Abstract: 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.

Abstract: 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.

Abstract: 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 d1. A PN junction forming portion of the N-type layer is diffused from depth d1 to depth d2 which is greater than depth d1 so as to form, with the P-type well, a PN junction of a photodiode at depth d2. Depths d1 as well as depths d2 of 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.
