  • Patent number: 8333188
    Abstract: A medicine ejection apparatus which ejects a medicine for medicating a user has a medicine ejecting unit, which has an element that generates energy for ejecting the medicine, a drive control unit which controls a drive start and a drive stop of the element, and an ejection amount determining unit, which determines a total amount of a medicine that is ejected from the medicine ejecting unit after the element performs a drive stop. The drive control unit enables the element to perform driving to eject an amount of medicine calculated from a difference between a set ejection amount and the total amount of medicine that has actually been ejected, when the total amount ejected, as determined by the ejection amount determining unit, is less than the set ejection amount.

  • Patent number: 8334931
    Abstract: An image processing apparatus according to the present invention extracts a characteristic value of a luminance in relation to respective fields of an input video, and determines the presence of a scene change between adjacent fields. A gamma curve is then generated on the basis of the magnitude of the characteristic value. When a difference in the characteristic value between fields is larger than a predetermined value and a scene change does not exist, the gamma curve to be applied to a subsequent field is modified such that the correction characteristic of the gamma curve does not vary rapidly. The luminance is then corrected using the modified gamma curve.

  • Patent number: 8335021
    Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

  • Patent number: 8334883
    Abstract: Image display which accesses an image containing multispectral data and a spectral device model for a reflective display. The reflective display renders the image by modulation of an ambient illuminant and is driven by color primary signals for corresponding color primaries. A spectral power distribution of a direct irradiance of a current ambient illuminant is cyclically and repetitively estimated by using a measurement of the spectral power distribution of the direct irradiance of the current ambient illuminant. Color primary signals are determined by using the estimation of the spectral power distribution of the direct irradiance of the current ambient illuminant, the spectral device model, and the multispectral image data. The reflective display is driven by the determined color primary signals, such that the multispectral image data rendered on the reflective display simulates the appearance of the multispectral image data calorimetrically under the current ambient illuminant.
