摘要： When an object contains a plenty of edge components such as a forest, the image having the highest total of differentiation values of the luminance value may not be an image focused on what is intended by a person who is performing imaging. Moreover, when the point to be focused is unclear, there is no principle for deciding which of the focusing lens positions obtained from the image of a large- frame area is to be employed. For this, there is provided an imaging lens position control device for holding information on high-frequency component distribution at the candidate focus lens positions and selecting information which is considered to have the optimal distribution among the plurality of distribution information, thereby controlling the focus lens position for imaging. Moreover, the imaging lens position control device can improve the processing accuracy for focusing and reduce the processing load by making the focus lens position focused according to a small-frame area reference as an imaging lens position.
摘要翻译：当物体包含诸如森林的大量边缘成分时，具有亮度值的微分值总数最高的图像可能不是聚焦于正在进行成像的人的意图的图像。此外，当要聚焦的点不清楚时，没有任何原理来决定采用从大帧区域的图像获得的聚焦透镜位置中哪一个。为此，提供了一种用于保持在候选聚焦透镜位置处的高频分量分布信息的成像透镜位置控制装置，以及在多个分布信息中被认为具有最佳分布的选择信息，从而控制聚焦透镜成像位置。此外，成像透镜位置控制装置可以通过使根据小帧区域参考而聚焦的聚焦透镜位置作为成像透镜位置来提高聚焦的处理精度并降低处理负荷。

摘要： A method and an apparatus for controlling a focus in a photographing device are provided to effectively control the focus both in high and low brightness states by using different threshold values for the high and low brightness states. An apparatus for controlling a focus in a photographing device includes a brightness sensor(110), a filter(130), a threshold value calculator(120) and a controller(140). The brightness sensor detects brightness values in respective pixels in an image of an object. The filter outputs output values corresponding to the sensed brightness values. The threshold value calculator counts the number of pixels having brightness values greater than a predetermined value, and calculates a threshold value from a ratio of the counted pixels in an overall pixel number in the image. The controller controls a position of a focusing lens by using the output values greater than the calculated threshold value.

摘要： The autofocus response characteristic can be improved. An image pickup sensor performs exposures (ex11,ex12) (C) in synchronism with a video vertical sync signal (VP1) (A). A camera signal processing part reads image signals obtained by the exposures (ex11,ex12) at timings (VR12,VR21), respectively (D). An AF detecting part derives the high frequency components of the video signals corresponding to an AF detection scale-down gate frame (which will be referred to simply as gate frame hereinafter) at the timing of the gate frame, then rectifies the derived high frequency components, and then produces focus evaluation values immediately after the timing of the gate frame. An AF module receives a plurality of focus evaluation values at a timing of AF module (AF2) (F), then produces such an autofocus control signal (LD3) that the focus position gets close to an in-focus position (G), and then moves a focus lens based on the autofocus control signal. The present invention may be applied to a video camera.
