IPC: G06T7/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method by which the fracture of a bump electrode with reference to a surface-mounting electronic component can be inspected with high reliability by a method wherein the bump electrode is irradiated with illumination light from an oblique direction with reference to the optical axis of a camera and the existence of the bump electrode is judged on the basis of the reflection position on the bump electrode of the illumination light on an image. SOLUTION: When the bump fracture of a ball grid array(BGA) chip 22 is inspected, a light source part 30A is first turned on, and the position of a first bright point appearing on the surface of every bump 22A is detected so as to be stored. Then, a light source part 30B is turned on, and the position of a second bright point is detected so as to be stored in the same manner. Then, on the basis of the stored positions of the first and second bright points at every bump 22A, the distance between the first bright point and the second bright point is computed for every bump, a computed result is compared with a threshold value which is set in advance, and the existence of every bump 22A is judged.  Thereby, since beams of illumination light L10A, L10B can be made incident on the optical axis K10 of a camera 23 from different sides in an oblique direction, a fracture can be inspected with high reliability.

Abstract: PURPOSE:To cope with the limit of the copying frequency to perform the copy control of high reliability by inserting copy information in the vertical blanking period of a video signal and executing or inhibiting recording in accordance with copy information at the time of recording. CONSTITUTION:At the time of recording an analog video signal, the video signal inputted from an input terminal 12 is converted to a digital signal and is subjected to processing such as compression by a picture processing circuit 3, and control information or the like is added by a recording/reproducing circuit 2, and this digital signal is recorded on a magnetic tape 14 by a rotary head 1. At this time, a control signal detecting circuit 7 detects copy information in the analog video signal, and a recording/reproducing control circuit 4 decides permission/inhibition of copy in accordance with the presence/absence of copy information. When copy is permitted, the recording/reproducing control circuit 4 adds copy information to the video signal and permits the recording/ reproducing circuit 2 to record the signal on the magnetic tape 14; but when it is inhibited, the circuit 4 inhibits the recording operation itself of the recording/reproducing circuit 2.

Then, light is generated by passing an electron beam through them and hitting it against phosphor stripes on the inside surface of a panel. In addition, the bend of the transmissive opening 1 is gradually increased in accordance with the increase of the incident angle of the electron beam as the transmissive opening 1 approaches an end of a horizontal axis from the center.  Additionally, the projection of the electron beam formed on the inside surface of the panel is straightened by matching the incident direction of the electron beam with the swelling direction of the edge of the transmissive opening 1 from the center of its long sides through its short sides.
