Abstract:
Players input their messages in their video game apparatuses and the messages are once collected at a server apparatus, thereafter they are distributed to all video game apparatuses from the game server apparatus. In a display screen of each video game apparatus, a chat window is displayed in order to display messages exchanged between the players on a game screen including a field and characters of the game. The chat window is sequentially enlarged up to a preset maximum number of lines when a new message is received from the game server apparatus. The chat window is sequentially reduced to the preset minimum number of lines when a predetermined time passes without any reception of new message or when the player performs a specific operation.
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:
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:
An information storage apparatus recognizes a traffic sign on a road expressed by a road surface image, and stores recognized traffic sign in association with its position information in a hard disk drive. By recognizing and storing information on the traffic sign in combination with the position information for the sake of traffic safety, information coverage in terms of traffic safety is updated to the most up-to-date condition for roads in the entire country.
