  • Patent number: 7929044
    Abstract: An autofocus searching method includes the following procedures. First, focus values of images, which are acquired during the movement of the object lens, are calculated, in which the focus value includes at least the intensity value of the image derived from the intensities of the pixels of the image. Next, focus searching is based on a first focus-searching step constant and a first focus-searching direction, in which the first focus-searching step constant is a function, e.g., the multiplication, of the focus value and a focus-searching step size. If the focus searching position moves across a peak of the focus values, it is then amended to be based on a second focus-searching direction and a second focus-searching step constant, in which the second focus-searching step constant is smaller than the first focus-searching step constant, and the second focus-searching direction is opposite to the first focus-searching direction.

  • Patent number: 7907205
    Abstract: A focus range is determined on the basis of an object distance, focal distance, and aperture value, after an autofocus operation. When SW2 is operated, an exposure is performed only during a period that a displacement of a blur in an optical-axis direction is within the focus range. If an exposure time for one exposure does not reach an exposure time to obtain an optimum exposure, a plurality of exposures are performed until a total exposure time reaches the exposure time to obtain the optimum exposure. When the plurality of exposures are performed, a plurality of images obtained are combined to generate an image with the optimum exposure.

  • Patent number: 7898593
    Abstract: The present invention provides synchronization and control between the wavelength of a multi-wavelength illuminator and the image frames acquired by a video camera. In accordance with the present invention, the trailing edge of a camera expose-signal triggers a pre-loaded digital value to be output from a FIFO buffer. The digital value selects a particular illumination wavelength either directly or through a voltage from a digital to analog converter. The FIFO may be periodically refilled, or it may be a circular register.

  • Patent number: 7872676
    Abstract: Methods, devices, and systems for offset compensation in an amplifier are disclosed, wherein the amplifier inputs may be exposed to large loads from an array of pixel columns coupled in parallel. During a sampling phase, an amplifier offset may be sampled by selectively coupling a first amplifier output to a first amplifier input and a second amplifier output to a second amplifier input. During a portion of the sampling phase, the first amplifier output may be buffered to a first storage element. During a different portion of the sampling phase, the second amplifier output may be buffered to a second storage element. To sense the pixel columns during an amplification phase, the first storage element and the second storage element are coupled to the first and second amplifier inputs, respectively, with the result that the amplifier offset is canceled from the amplifier output.

  • Patent number: 7868923
    Abstract: An optical system forms an optical image on an imager, and a read control block selects a read rule for the imager depending on a magnification addressed by a magnification address block. The imager transforms an optical image at an addressed area into electrical signals in compliance with the read rule. The read image signals are stored in n image memories, where n is the number of images necessary for ultra-resolution processing. Ultra-resolution processing is built up of a motion estimation block and a high-resolution image estimation block adapted to estimate image data having a high-resolution image sequence. A selector selects a basic image for motion estimation and an image that is estimated in terms of motion.

  • Patent number: 7830445
    Abstract: An image-pickup apparatus is disclosed which can prevent focus control from being performed on the basis of incorrect information on an object distance externally measured. The image-pickup apparatus includes a first detector which produces first information corresponding to a contrast state of a picked-up image, a second detector which receives light from an object to detect second information corresponding to a distance to the object, and a controller which performs focus control by using the first information and the second information. The controller performs the focus control by using the first information without using the second information when a light-receiving luminance level in the second detector is lower than a first value.
