Title: Charge-coupled device
Inventor: TAKENAKA KAZUHIRO
IPC: H01L21/339
Filed: 1986-12-02
Abstract: PURPOSE:To accelerate a charge transfer speed by dividing an electrode to which a transfer clock voltage is applied into three so that potential difference occurs among the electrodes. CONSTITUTION:An HI level clock is applied to a clock application terminal 4, a LOW level clock is applied to a clock application terminal 5, the clocks are connected to three electrodes 9, 10, 11, and the potential difference of the electrodes are formed by P-type diffused layers 6, 7. In order to form such the potential differences, the concentration of the layer 7 is increased larger than that of the layer 6. Thus, a potential distribution is eliminated at its predetermined part to form an electric field in the electrodes of the clocks. In this manner, an electric field is formed in a transfer gate to be able to be transferred at a high speed.

Patent JP-H04207280-A (JP)
Title: Video packet encoder
Inventor: NISHIDA MASAMI
IPC: H04N19/70
Filed: 1990-10-25
Abstract: PURPOSE:To efficiently perform packet encoding by performing the band division of a video signal, and performing multiplex delivery setting an undeletable packet by making a low-pass signal into an interframe code, and setting a deletable packet by making a high-pass signal into a motion detection code. CONSTITUTION:An undeletable identifier is attached on a low-pass encode data at an undeletable identifier attaching part 5, and a packet on which high- pass signal encode data is multiplexed is also sent to a packet delivery part 7. Meanwhile, the packet on which a deletable identifier is attached can be selectively deleted by sending the packet by attaching the deletable identifier on the high-pass signal encode data and the undeletable identifier on low-pass signal encode data when it is inevitable that the deletion of the packet is performed at a network side. As a result, the deletion of the packet for the low-pass signal encode data can be prevented from occurring. Since a frame decoding result is used in only the detection of a moving area and a still area in such motion encoding, an error can be eliminated when the block is decoded at the next time without receiving the influence of the error even when it occurs.

When the subject distance is long, a flash light emission device performs light emission control, but when a short-focal-length photographic lens is mounted, dimming control is switched and when a long-focal-length lens is mounted, the switching distance is increasd so that flashmatic control is usable even if the subject distance is long. Consequently, under-exposure caused by the error in range finding according to the focal length of the photographic lens is long or short is re duced.
