  • Patent number: 6781629
    Abstract: The digital camera and the image reproducing apparatus and method can reduce a waiting time when a compressed image recorded in a recording medium is reproduced and displayed on a display device, and allows the user to promptly check the reproduced image. Before the user inputs an instruction for sequential or reverse frame feeding, image data is beforehand read out from a recording medium, decompressed, and held in a memory inside the digital camera as prepared images for display. When the instruction for the frame feeding is given, the corresponding prepared image is read out from the memory and then output to the liquid crystal monitor, thereby reducing the reproduction time to achieve fast reproduction. A range of the image which is subjected to a preceding read is a frame image before or after the currently displayed frame, all thumbnail images stored in the recording medium, all main images stored in the recording medium, or all of main images and the thumbnail.

  • Patent number: 6774937
    Abstract: In the case where an output signal of an image pickup device is compressed and is transmitted through a transmission path with band limitation, when a conventional compression and expansion technique is directly applied, there is a lot of waste and a circuit scale becomes large, so that the cost of the system is raised. In an image processing system or a camera system of the invention in which an output signal of an image pickup device is compressed and is transmitted, the output signal of the image pickup device is made to pass through a luminance signal forming portion and a contour correcting signal forming portion, so that the signal is divided into a luminance signal and a contour correcting signal. These signals are separately compressed by compression processing portions, and multiplexed by a multiplexing portion, and then transmitted through a transmission path with band limitation such as a USB.

  • Patent number: 6765618
    Abstract: A subject selection device comprises a light source and an imaging device, such as a CCD, having a plurality of photo-diodes. The light source radiates a distance measuring light beam toward a plurality of objects. A reflected light beam, generated by the objects due to the distance measuring light beam, is received by the, photo-diodes. A signal charge is integrated in each of the photo-diodes, so that three-dimensional information, which includes distances from the camera to each point on a surface of the objects, is obtained. A histogram indicating a distribution of the distances is generated. Based on a peak value of the histogram, a subject to be photographed is selected from the objects. An in-focus portion indicating device indicates a portion of the subject, which is in focus, based on the peak value.

  • Patent number: 6744469
    Abstract: A method and system provide for real-time compensation of an imaging system for variations in illumination intensity. An illumination system provides reflected illumination, and a charge coupled device system directly detects the reflected illumination from the illumination system. The CCD system then converts the reflected illumination into illumination data and a host processor converts the illumination data into adjusted control data and final image data. The adjusted control data is based on an illumination profile and a reference illumination intensity. The reference illumination intensity is measured before each document with a compensation reference, and is compared to the illumination profile to adjust control parameters in a real-time mode. Directly measuring the illumination intensity with the CCD system allows for a reduction in parts, manufacturing steps, and errors.

  • Patent number: 6704050
    Abstract: An image sensing device comprising active pixels is disclosed, each pixel having a charge accumulation region for collecting charges generated by a photosensitive element such as a photodiode. A linear voltage to current converter, current mirrors, and a differential amplifier generate an output signal and minimize fixed pattern noise and improve the signal to noise ratio. Image quality is improved by reducing pixel blooming and image smearing through an improved method for resetting the pixels with a bias voltage reference which is less than Vdd. Active circuitry and physical device layout reduce the effects of IR voltage drops along the bus lines in a massive pixel array.

  • Patent number: 6700615
    Abstract: An autofocus apparatus sets a portion of an image frame as an AF area. Then, in first image-pickup, acquires first image data for the AF area within the image frame according to a first light flux from an object passing through an aperture of the diaphragm when the diaphragm is not shifted. Further, in second image-pickup, acquires second image data for the AF area within the image frame according to a second light flux from the object passing through the aperture of the diaphragm when the diaphragm is shifted in one vertical direction with respect to the optical axis. A cross correlation between the first image data and the second image data is computed, and a distance up to a focus position of the focal lens as well as a direction thereof is computed according to the cross correlation. Then, the focal lens is driven to the focus position.
