  • Patent number: 8577216
    Abstract: The disclosure relates to techniques for calibration of an auto-focus process in an image capture device. The techniques may involve calibration of a lens actuator used to move a lens within a search range during an auto-focus process. For example, an image capture device may adjust reference positions for the search range based on lens positions selected for different focus conditions. The different focus conditions may include a far focus condition and a near focus condition. The focus conditions may be determined based on a detected environment in which the device is used. Detection of an indoor environment may indicate a likelihood of near object focus, while detection of an outdoor environment may indicate a likelihood of far object focus. An image capture device may detect indoor and outdoor environments based on lighting, exposure, or other conditions.

  • Patent number: 8326139
    Abstract: In a camera system according to the present invention, a lens controller obtains an exposure synchronizing signal that is generated by a camera controller from a camera body, causes a configuration formed of a first encoder, a second encoder and a counter to detect the position of a focus lens according to the obtained exposure synchronizing signal, and notifies the camera body of the detected position of the focus lens. The camera controller associates the position of the focus lens or the mechanism member obtained from the lens controller with an AF evaluation value based on the exposure synchronizing signal, and controls an autofocus operation of the camera system based on the position and AF evaluation value that are associated with each other. With this configuration, it is possible to improve the accuracy of an autofocus operation with a contrast system.

  • Patent number: 8270825
    Abstract: A photographic apparatus infers a user's photographic intent and accordingly switches between a manual shoot mode and an automatic shoot mode. In the manual shoot mode, processing to save photographic image data is timed in accordance with the user operating a user-operable shutter element, while in the automatic shoot mode, such processing is conducted independently of shutter element operations. A photographic unit photographs a scene, acquires photographic image data of a subject, and then executes processing for saving the photographic image data. An intention judgment information detector detects intention judgment information used to judge the photographic intent of the user. A controller makes an intention judgment using the intention judgment information from the intention judgment information detector, and according to the intention judgment result, causes the photographic unit to selectively execute the operations for one of the modes.
