Having Indicator Patents (Class 396/147)
  • Patent number: 10324268
    Abstract: Autofocusing a camera while zooming may include zooming the lens to a first zoom position, measuring a first object distance from the camera to an object on which to focus, determining a first focus start position using the first object distance, performing a first autofocus using the first focus start position as a starting point, thereby determining a first focus position. A first lookup object distance may be determined based on the first determined focus position. A first correction factor may be calculated as a ratio between the first lookup object distance and the first object distance. The lens may be zoomed to a second zoom position, and a second focus position may be determined using a second object distance based on the first object distance and a second correction factor based on depths of field at the second and first zoom positions.

  • Patent number: 10205928
    Abstract: An image processing apparatus free from the inconvenience of an increase in the number of focal positions for image pickup or reduction of the distance accuracy. An optical imaging system forms an object image and an image pickup device picks up the formed object image. A first range image is generated from a plurality of images picked up by the image pickup device and having parallax. A second range image is generated from a plurality of images picked up by the image pickup device and having different degrees of focus at respective corresponding locations therein. A synthesis coefficient is calculated according to the depth of field of a main object selected from objects shown in the object image. A synthesized range image is generated by synthesizing the generated first range image and second range image using the calculated synthesis coefficient.

The camera restriction prevents a user from taking a picture of a subject if the device has not been steadily focused on the subject in question for a predetermined period of time. In short, this process extends the normal camera-taking procedure and thus requires the camera user to take pictures in a conspicuous manner—the rationale being that a camera user would be less likely to take unauthorized pictures if such actions could be easily recognized. The camera restriction can be communicated to the device via a wireless communication network.

A wavelength-selective optical film which transmits the first wavelength region light and reflects the second wavelength region light is disposed inside the optical element. The optical observation apparatus superimposes an image formed by the second wavelength region light reflected by the wavelength-selective optical film on an object image formed by the first wavelength region light transmitted through the wavelength-selective optical film to cause an observer to observe the object image with the superimposed image through the eyepiece part. The optical observation apparatus can superimpose an optional image on the object image to enable the observer to observe these images without a deterioration of viewfinder performance.

  • Patent number: 7881600
    Abstract: A photographing device for photographing an object in a photographing area has a detection processor, and first and second determination processors. The detection processor conducts repetitive detection processes for detecting a specific area where a specific object appears in the photographing area. The first determination processor determines the detected specific area to be a designated area. The second determination processor re-determines a substitute area including the detected specific area that has been latest detected by the detection processor to be the designated area if the specific area is not detected in the detection process.

  • Patent number: 7877006
    Abstract: A focus information display system is provided in which focus state detection that is performed during automatic focusing (AF) and the like is also performed during manual focusing (MF) and the like to display focus information indicating a focus state. By arranging a focus position range at which a correct focus state is determined when a correct focus display is being performed to be wider than a focus position range at which a correct focus state is determined when an out-of-focus display is being performed, stabilization of a state of correct focus display is achieved without jeopardizing correct focusing accuracy when performing focusing according to a focus information display.

  • Patent number: 7865075
    Abstract: An electronic camera detects a person's face image from an object image obtained by photographing an object, executes an enlarging process on the detected face image so as to obtain a face image whose face size is suitable, and displays the face image which is enlarged into the suitable size on a display device. When a plurality of people are present on the object image, the enlarged face images are switched by an image operating switch. As a result, the switched face image is displayed on the display device.

  • Patent number: 7844174
    Abstract: A method and system for additively, manually sequentially or manually in parallel, selecting multiple points or regions of interest in the analog or digital viewfinder of a photo or video camera with automatic controls like auto-focusing, auto-metering and auto white-balancing. Points or regions capable of being selected, within a grid of elements comprising a camera's evaluative matrix and represented to the user in a viewfinder or other display, may be hard-coded (pre-defined, selectable regions) or any point, pixel, or group of pixels. Data from the selected regions is used to simultaneously, dynamically adjust focus related parameters, light metering and white balancing of the camera and is tied into these features. Point selection may be via touch screen or by holding down a lock button. The selected points or regions may be applied to focus and aperture related adjustments or for any other camera function related to measurement of the scene.

  • Patent number: 7711256
    Abstract: Methods and devices for implementing a camera restriction on a wireless handheld communication device. As more handheld devices incorporate camera functionalities, organizations and individuals with privacy concerns are more vulnerable to unauthorized disclosure. The camera restriction prevents a user from taking a picture of a subject if the device has not been steadily focused on the subject in question for a predetermined period of time. In short, this process extends the normal camera-taking procedure and thus requires the camera user to take pictures in a conspicuous manner—the rationale being that a camera user would be less likely to take unauthorized pictures if such actions could be easily recognized. The camera restriction can be communicated to the device via a wireless communication network. Additionally, the restrictions and boundaries can be communicated to the device as part of an IT security policy.
