摘要： An automatic focusing apparatus repetitively detects a defocus amount of a photographing lens, discriminates whether or not an object is moving, and calculates a pursuit correction amount for a moving object on the basis of present and previous defocus amounts. When a non-moving object is discriminated, a drive amount of the lens is calculated on the basis of the present defocus amount, and when a moving object is discriminated the drive amount is calculated on the basis of a pursuit drive amount as a sum of the present defocus amount and the pursuit correction amount. A pursuit enable/disable determining device determines whether the drive amount is calculated on the basis of the discrimination result or on the basis of the present defocus amount. When a drive direction of the lens is reversed, the pursuit enable/disable determining device causes calculation of the drive amount of the photographing lens on the basis of the present defocus amount for driving the lens in a predetermined number of drive operations after the reversal.

摘要： Either of two power off modes can be selected in a digital camera that reads out images from an image-capturing element, temporarily stores them in a buffer memory and then transfers and records the images from the buffer memory into a recording medium. In a first power off mode, the supply of stabilized power is stopped in response to a main switch off operation only after unrecorded images present in the buffer memory are all recorded into the recording medium. In a second power off mode, the supply of the stabilized power is stopped immediately in response to a main switch off operation regardless of whether or not there are yet-to-be recorded images present in the buffer memory. The power is cut off in conformance to the current power off mode setting when the main switch is turned off.

摘要： An automatic focus state detection device executes focus adjustment by taking environmental factors such as temperature and power source voltage into consideration. The temperature of the camera, the power source voltage of the battery in the camera, and the posture of the camera are detected. Then, lens driving times for six representative points of the driving lens distance are computed. A driving time table is produced, and the defocus amount is detected. Then, based on the updated driving time table, the lens driving time corresponding to the current defocus amount is computed. Finally, the timing for each sequential process from release to start of exposure is determined. In this manner, the driving time is computed by taking the temperature, the power source voltage, and the posture into consideration, and a more accurate estimation of the lens driving time is realized.

摘要： An automatic focus adjustment device that can effect focussing on a moving subject. The automatic focus adjustment device includes a lens driving device, a focus state detection device that detects the defocus amount, an image velocity computation device that computes the subject image movement velocity, and a moving subject prediction device that computes a predicted value for the defocus amount at exposure based on the defocus amounts and the subject image movement velocity. The device also includes a predicted position control device that scrolls the shooting lens by the predicted value, a position velocity control device that controls the scrolling amount in accordance with the defocus amount and the amount of change of the defocus amount with time, a determination device that determines whether or not the control action of the predicted position control device can be completed before exposure, and prior to a release a selection device selects control by the predicted position control device. After release, the selection device selects control by the predicted position control device when the determination device determines the control action can be completed. Otherwise, the selection device selects control by the position velocity control device.
