  • Patent number: 7126634
    Abstract: The image processing system includes: an image pickup apparatus (10) including image pickup elements of a color difference line sequential system that outputs, as video signals, a luminance signal (Y) and a line sequential, color difference signal (U/V); and an image processing apparatus (20) which includes a signal interpolator (21) for interpolating the line sequential color difference signal (U/V) to separate the line sequential color difference signal (U/V) into two color difference signals (V) and (U). With this configuration, only two video signal lines are required to connect the image pickup apparatus (10) and the image processing apparatus (20), and even though the number of signal lines is reduced, image quality deterioration is suppressed.

  • Patent number: 7126636
    Abstract: A low-noise CMOS active pixel for image sensors comprises a photosensitive element (PD), a feedback capacitive element (CF) with a capacitance CF, and four transistors, namely a first transistor (M1), two reset transistors (M3, M4) and one pixel selection transistor (M2). These components are laid out and controlled in such a way that the first transistor (M1) is mounted as an amplifier during the pixel reset phase and as a follower during the read phase. The reset transistors (M3, M4) are parallel-connected so that one of them (M4) compensates for the negative effects of the other transistor (M3) on the node common to the two transistors.

  • Patent number: 7126640
    Abstract: Provided is control relating to autofocusing in an image sensing apparatus having an image sensing unit for photoelectrically converting an optical image of a subject to obtain an image signal representing the subject, and an autofocus function, the apparatus being capable of performing photography using a fill-in light emission unit. Control includes setting a charge accumulation period of the image sensing unit, deciding light-emission time of the fill-in light emission unit based upon the charge accumulation period that has been set, performing control in such a manner that the fill-in light emission unit is caused to emit light for the decided light-emission time in sync with start of the charge accumulation period, and performing focusing control based upon the image signal obtained from the image sensing unit. Control of the fill-in light emission unit is executed repeatedly during control of focusing.

  • Patent number: 7098941
    Abstract: An image recording surface of an exposed instant film is held so as to face an optical head module. Read light (white light) emitted from a light source passes a transparent portion of a color-separation filter, a first mirror, a first graded-index-type optical fiber array, and a second mirror in order. Then, the read light is radiated toward an instant film from an opening of the optical head module. The second mirror is set to a read position where the read light is inclined by a predetermined angle relative to the instant film. The read light is reflected by the image recording surface of the instant film and enters a line-CCD sensor via a second graded-index-type optical fiber array. By moving the optical head module in a sub-scanning direction, it is possible to read an image from the instant film.
