  • Patent number: 9838589
    Abstract: An imaging apparatus including an exchangeable lens and a camera body. The camera body transmits a synchronizing signal having the same cycle as the cycle of the capturing operation in the imaging unit, to the interchangeable lens. The controller of the exchangeable lens performs a zoom tracking control by determining the focus position of the focus lens from the position of the zoom lens detected by the position detector by referring to the relation information, and controlling the focus lens driver to move the focus lens to the determined focus position, The controller performs the zoom tracking control in a cycle (for example, one-eighth) shorter than a cycle indicated by the synchronizing signal received from the camera body.

  • Patent number: 9645352
    Abstract: The image pickup apparatus has a focus lens that adjusts focus on a subject, an operating section (an MF operation ring) that accepts user's operation, and a focus-lens driver that drives the focus lens in response to the user's operation. The focus-lens driver drives the focus lens so that a rotation amount at the operating section, which is required for moving a focus position by unit distance, is maintained at a constant level with no regard to a subject distance.

  • Patent number: 7697030
    Abstract: A monitor camera is provided with a control device which carries out a predetermined process in response to an input of a trigger signal. The control device has an arrangement in that continuous images are successively inputted from a camera unit thereto and in that a detection of a moving object is carried out by detecting a change in images in a moving-object detector. When no change in images is detected by the moving-object detector within a predetermined time after the input of a trigger signal from a detection sensor to a trigger signal input unit, the control device determines the trigger signal inputted to the trigger signal input unit as valid. Then, only when the valid trigger signal has been detected, an abnormality process is carried out. Consequently, it is possible to prevent the abnormality process from being performed upon erroneous detection of a normal state as an abnormal state.

  • Publication number: 20020114015
    Abstract: An AF control portion of a digital camera has therein a histogram generating circuit for generating a histogram of widths of edges in an AF area, a noise eliminating portion for eliminating noise components from the histogram, a histogram evaluating portion for calculating an evaluation value indicative of the degree of achieving focus from the histogram, and a contrast calculating circuit for calculating contrast in the AF area. Further, a driving amount determining portion for determining an amount of driving a focusing lens, and a driving direction determining portion for determining a direction of driving the focusing lens are provided. The driving direction determining portion determines the direction of driving the focusing lens by using contrast. The driving amount determining portion positions the focusing lens to an in-focus position promptly with high precision while changing the driving amount by using the evaluation value of the histogram and the contrast.
