Abstract: A video camera having camera-shake detection function divides an image sensed picture into a plurality of blocks and binary codes the luminance signal in each pixel in each block. The presence of a binary coded data of "1" is detected for each horizontal line and vertical line in each block, whereby the presence of at least one causes data "1" to be stored in the bit position in the memory corresponding to the line. Accordingly, data representing the distribution of an object in the vertical direction and the horizontal direction are obtained for each block. By calculating the data correlation between consecutive frames, a motion vector of the object for each block is specified, whereby a motion vector representing the entire picture is selected by subjecting the motion vectors of all blocks to majority decision logic process. In accordance with this selected motion vector, the movement of the object caused by camera-shake is corrected appropriately.

Abstract: A method for reading a chain (34) of code symbols, arranged in a ring form in the lower area of a transparent bottle (10), by recording at least the lower bottle area through the bottle neck by means of a camera (24) and simultaneously illuminating the lower bottle area from below is described. Using the camera (24), a snapshot of the lower bottle area with the entire code symbol chain (34) is made from inside the bottle at a relative speed of rotation of zero between camera (24), bottle (10) and source of illumination (32), and stored as a picture for later decoding of the code symbol chain. The code reading method is a very fast method because the fraction of the second in which the bottle (10) is in one line with the camera (24) and the source of illumination (32) is sufficient for reading the code. The recorded picture of the code symbol chain (34) is analysed in histogram technique by comparing it with a stored ring-shaped template subdivided into sectors.

Abstract: Techniques of video cameras or the like which may be effectively used with photo-camera, for instance, are disclosed. In response to the detection of a greater image pick-up signal level change than a predetermined extent, a shutter pulse is generated. In addition, in response to the shutter button operation, the blanking area of image is increased or reduced to provide a special effect of indicating the shutter operation. The output signal of an optical sensor having the same characteristic as the image pick-up device is integrated, and when the integral signal exceeds a predetermined value, the AGC circuit gain is reduced to a predetermined extent to prevent the image pick-up signal level from being excessively increased. Further, when the integral signal exceeds a predetermined value, a read pulse is supplied to the image pick-up device, thus permitting charge accumulation time increase in the image pick-up device to increase the sensitivity without leading to saturation of the charge accumulation.

Thus, when a circuit board is placed on the probe plate the stationary frame is moved such that the movable frame is in abutting relation with the perimeter of the board. The stationary frame is then latched into place to prevent any further movement. Pressurized fluid is then provided to the piston chambers of the stationary frame, forcing the pistons in a downward direction. The movement of the pistons then cause the movable frame to move downwardly such that the circuit board is firmly and reliably seated on the test probes and electrical continuity between the electronic components on the board and the test equipment is provided.
