Abstract: Adjacent pixels in a pixel circuit of an imaging device use a primary capacitance, an amplifying transistor, a reset switch and a selection switch in common. Each pixel has a photodiode and a transfer switch having first and second gates provided on the photodiode side and the primary capacitance side, respectively. In a pixel downsampling read mode, the first and second gate voltages of each pixel to be discarded are brought to high level, and thereafter the first and second gate voltages of each pixel to be read are brought to high level, to transfer charge generated in the photodiode of the pixel to be read to the primary capacitance and the photodiode in each pixel to be discarded. This enables reduction of the potential of the primary capacitance, and hence reduction of the pixel sensitivity than using only the primary capacitance to store charge transferred from the transfer switch.

Abstract: In an imaging device having an all-pixel read mode for reading signals from all pixels and a pixel downsampling read mode for reading signals by appropriately discarding pixels, adjacent ones of pixels use a floating diffusion capacitance, an amplifying transistor, a reset switch and a selection switch in common. In the pixel downsampling read mode, not only a primary capacitance but also a photodiode in each pixel to be discarded are used as capacitances for storing signal charges transferred from transfer switches. This makes it possible to lower the gate voltage of the amplifying transistor as compared with the case of using only the primary capacitance as a capacitance for storing signal charges transferred from a transfer switch to reduce the sensitivity of the pixels, thereby reducing the occurrence of flicker.

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: 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.

Abstract: Multiple video game apparatuses are connected to a game server apparatus. This network game progresses when players of the respective video game apparatuses exchange messages via the game server apparatus. When a predetermined event is generated by processing in the game server apparatus, a specific message is transmitted to each video game apparatus. In a chat window provided on a display screen of each video game apparatus, the message sent from the game server apparatus is scrolled and displayed from the bottom to the top. When the specific message reaches an uppermost portion of the chat window, a lock window is set and the specific message is displayed therein. The specific message in the lock window is not erased by the reception of a next message.

Abstract: A map display device includes a display for displaying map data, a position detection means for detecting a position of a subject vehicle, a map data storage means for storing the map data and a map data process means for processing the map data. The map data process means determines whether the subject vehicle is traveling outside of a road on a map displayed on the display based on the current position of the subject vehicle. The map data process means updates the map data upon receiving an affirmative response for confirmation of an update of a portion of the map data including a path of the current position of the subject vehicle on the map.

Abstract: In a state where a driver sees a region near a vehicle, a finally-requested output-shaft torque is set so that a response is hastened in a deceleration and slowed in an acceleration. Thereby, a vehicle takes a forward descending position in which the front end of the vehicle is descending, which gives a driver a sense of deceleration or a sense of turning. Further, this position causes a front wheel load acting on the ground to increase and a rear wheel load acting on the ground to decrease, in comparison to a normal position. This thereby makes it easier for the vehicle to decelerate when practically decelerating or turning, and further enables turning to slightly over-steer. A resultant vehicular kinetic characteristic becomes comparable with a sense that is expected by the driver.
