  • Patent number: 9488898
    Abstract: The invention provides an imaging apparatus and a focus control method in which an optimal AF system can be selected in accordance with an environment in which an image of a photographic subject is taken, an imaging condition in which the image is taken, etc. so that the quality of the taken image can be improved. A system control portion 11 of the imaging apparatus selects and executes one from focus control based on a phase difference AF system and focus control based on a contrast AF system in accordance with the magnitude relation between a determination threshold set for an F-number and the set F-number in the case where an AF instruction has been issued. The system control portion 11 can vary the determination threshold in accordance with an exposure value in the case where the AF instruction has been issued.

  • Patent number: 9479705
    Abstract: An exposure value adjustment apparatus, method, and non-transitory tangible machine-readable medium thereof are provided. The exposure value adjustment apparatus includes a camera module and a processor. The camera module captures a reference image by a base exposure value. The processor generates a histogram of the reference image, divides the histogram into a low partial histogram, a middle partial histogram, and a high partial histogram by a first threshold and a second threshold, decides a high exposure value according to the low partial histogram and the middle partial histogram, decides a low exposure value according to the high partial histogram and the middle partial histogram, and decides a middle exposure value according to the high exposure value and the low exposure value. The low exposure value is lower than the high exposure value, and the middle exposure value is between the high exposure value and the low exposure value.

  • Patent number: 9363447
    Abstract: Apparatus and methods are provided for obtaining high dynamic range images using a low dynamic range image sensor. The scene is exposed to the image sensor in a spatially varying manner. A variable-transmittance mask, which is interposed between the scene and the image sensor, imposes a spatially varying attenuation on the scene light incident on the image sensor. The mask includes light transmitting cells whose transmittance is controlled by application of suitable control signals. The mask is configured to generate a spatially varying light attenuation pattern across the image sensor. The image frame sensed by the image sensor is normalized with respect to the spatially varying light attenuation pattern. The normalized image data can be interpolated to account for image sensor pixels that are either under or over exposed to enhance the dynamic range of the image sensor.
