Publication number: 20080316336Abstract: An image pickup apparatus that performs accurate correction processing for a pixel that outputs a non-reproducible high-level signal having a continuity with respect to an adjacent pixel is provided. The image pickup apparatus extracts data corresponding to a pixel of an image pickup element that generates an output value equal to or more than a predetermined value, and determines, within a predetermined area of a captured image, whether a predetermined number or more of pixels that generate an output value having the predetermined level are continuously adjacent to one another in the same direction, irrespective of the color received by the pixel. Then, if it is determined that the predetermined number or more of pixels are continuously adjacent to one another in the same direction, the pixels are indicated as targets and the outputs of the target pixels are corrected.Type: ApplicationFiled: June 20, 2008Publication date: December 25, 2008Applicant: CANON KABUSHIKI KAISHAInventor: Koji Oshima

Publication number: 20080312037Abstract: A control apparatus for an automatic transmission including a gear-type transmission mechanism connected to an output shaft of a motive power source, the gear-type transmission including plural frictional engagement elements. The control apparatus senses a power-on downshift in which the frictional engagement elements are engaged during a downshift in a driving state of the motive power source, controls the motive power source so that in the power-on downshift an output of the motive power source is reduced, counts a time during which an input rotational speed of the transmission mechanism approximates an after-shift synchronous rotational speed, and controls the motive power source so that, if the time exceeds a predetermined time while the output of the motive power source is reduced, recovery from the reduction of the output of the motive power source is attained.Type: ApplicationFiled: March 8, 2006Publication date: December 18, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroomi Toi, Koji Hattori, Ayumu Sagawa, Koji Oshima, Hiromichi Kimura

Publication number: 20080269013Abstract: “Threshold A is substituted in a power-on state, “threshold B”, which is lower than “threshold A”, is substituted in a power-off state, and “threshold C”, which is lower than “threshold B” is substituted during a brake operation, as a rapid deceleration determination threshold. The rotational speed of an output shaft of an automatic transmission and the rapid deceleration determination threshold are compared to determine whether a vehicle is rapidly decelerating. The engagement state of a lock-up clutch is controlled based on whether the vehicle is rapidly decelerating.Type: ApplicationFiled: April 25, 2008Publication date: October 30, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shun MINAKI, Koji Oshima

Publication number: 20060237275Abstract: The vehicle start determining unit determines a vehicle starting state based on a vehicle speed and an accelerator pedal press-down degree. When the vehicle starting state is determined, the target slip value determining unit determines a target slip rotational speed based on the actual accelerator pedal press-down degree. In receipt of a signal indicating initiation of the control upon the previous slip control, the running history storing unit stores a change of the vehicle speed over time after the relevant timing, and sets a running history flag to an on state when detecting that the vehicle speed has exceeded a prescribed threshold value. In receipt of the target slip rotational speed and the running history flag, if the running history flag is in the on state, the lock-up clutch control unit carries out the slip control according to the target slip rotational speed.Type: ApplicationFiled: April 17, 2006Publication date: October 26, 2006Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirofumi Fujita, Hiromichi Kimura, Koji Oshima, Tomohiro Asami, Takahiro Kondo, Shun Minaki

Patent number: 6997837Abstract: In a shift control system of an automatic transmission for a vehicle, an engaging torque applied to a predetermined friction element that has been engaged to establish a predetermined gear stage of the automatic transmission during running of the vehicle is gradually decreased to generate a slip in the predetermined friction element. Based on the engagigng torque of the friction element and a command value output to generate the engaging torque to the friction element, a predetermined relationship used for determining the command value for generating a required engaging torque is corrected. Learning quality or accuracy with respect to the predetermined relationship between the engaging torque of the friction element and the control value for generating the engaging torque may be sufficiently ensured.Type: GrantFiled: April 6, 2004Date of Patent: February 14, 2006Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koji Oshima, Hiromichi Kimura, Kazuyuki Watanabe, Toshio Sugimura

Patent number: 6979280Abstract: In a control apparatus for a vehicle, when a coast downshifting is performed in response to a downshifting command from a vehicle operator during braking operation under the fuel cut control, the braking force of the wheel brake is increased so as to increase the deceleration. This makes it possible to achieve a predetermined deceleration with a good response to the deceleration request of the vehicle operator represented by the downshifting command. The control apparatus is structured to decrease the braking force of the wheel brake such that the increase in the engine braking force is offset by the inertia caused by the rise in the engine speed resulting from downshifting upon the coast downshifting due to the vehicle speed increase. The control apparatus for the vehicle, thus, reduces the shock caused by the sharp increase in the engine braking force.Type: GrantFiled: July 14, 2003Date of Patent: December 27, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koji Oshima, Hiromichi Kimura
