Publication number: 20080217791Abstract: In a semiconductor device of the present invention, an electrode pad is formed on a surface of a semiconductor substrate, and in the electrode pad, two different areas: a connection area of through wiring electrically connected to a through wiring; and a pad area for inspection that keeps away from an opening on the surface of a through hole, are set. Accordingly, the electrode pad can be adequately prevented from being damaged due to contact of a probe, providing a high yield and reliability of the semiconductor device. That is, because the through hole is not opened directly below the pad area for inspection with which the probe is in contact upon operation inspection of devices, a mechanical strength of the electrode pad against the probe can be maintained in a high level.Type: ApplicationFiled: March 3, 2008Publication date: September 11, 2008Applicant: OLYMPUS CORPORATIONInventors: Kazuaki Kojima, Takatoshi Igarashi, Koichi Shiotani, Kazuya Matsumoto

Patent number: 5561474Abstract: The color video camera has a processing circuit which converts electrical signals obtained from an imager into a luminance signal and color-difference signals. The color video camera further includes a memory which stores a table of values designating color saturation levels and corresponding to a specific hue of a background color. The memory outputs a color saturation level based on the color difference signals obtained by imaging an object on a background of the specific hue. This color saturation level is compared with the luminance signal, and based on the comparison results the luminance signal and color difference signals are separated into components corresponding to the background area and components corresponding to the object area.Type: GrantFiled: May 18, 1995Date of Patent: October 1, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuaki Kojima, Tetsuya Kuno, Hiroaki Sugiura, Takeshi Yamada

Patent number: 5488429Abstract: A flesh-tone area is detected based on color-difference and luminance signals constituting video signals, and luminance correction, color correction, and aperture correction are performed only on the flesh-tone area or a human face area identified in the flesh-tone area. The setting of a focus area or the setting of a photometric area for iris control, automatic gain control, automatic shutter control, etc., in a video camera, is performed with respect to the flesh-tone area or the human face area. Furthermore, based on the color-difference and luminance signals constituting the video signals, a background area is detected, and the video signals are divided into components representing a background area and components representing an object area. An image signal of a desired hue or a still image is superimposed on the detected background area, or special processing is performed on the video signals representing the object area other than the detected background area.Type: GrantFiled: December 31, 1992Date of Patent: January 30, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuaki Kojima, Tetsuya Kuno, Hiroaki Sugiura, Takeshi Yamada
