  • Patent number: 7982921
    Abstract: An image processing device is provided which corrects error pixels without using a line buffer even in the case of using an image sensor with a structure having a plurality of sensors arranged in series. It has a detecting component for detecting the presence or absence of a factor of black line and Kth error pixel correcting processing components each for receiving the Kth pixel signal among the pixel signals output in N divisions, and for correcting error pixels. When the factor of black line is detected at a boundary between Kth and (K?1)th division outputs, the Kth error pixel correcting processing component notifies the (K?1)th error pixel correcting processing component of neighboring pixel information about the error pixels, and the (K?1)th error pixel correcting processing component corrects the error pixels at the boundary in response to the neighboring pixel information notified and the (K?1)th pixel signal.

  • Patent number: 7957571
    Abstract: In step S1, image data obtained by imaging is input to an image input unit (1). In step S2, the diagnosis result obtained by a doctor using the image data obtained by imaging is input as diagnosis information to a diagnosis information input unit (2). In step S3, a keyword table (7) is searched for a keyword input to the diagnosis information input unit (2) or a diagnosis information analyzing unit (3). In step S4, a parameter determining unit (5) selects an initial value parameter used in an image search unit (4) from an initial value table (8) on the basis of the input keyword. In steps S5 and S6, the image search unit (4) determines the optimization degree of the selected parameter by applying the parameter to the input image on the basis of the area or connectivity of a morbid region, and also extracts a morbid region by using a general computer aided diagnosis technique.
