Patent ID: 8325253

Claim:
A pixel defect correction device comprising: pixel defect detection means configured to (i) receive a pixel signal, (ii) detect defects of the pixel signal, and (iii) measure a defect count; timing means; and an overcorrection calculation section configured to (i) compare a measured value of the pixel defect detection means with an estimated value of the pixel signal after the elapse of a predetermined time measured by timing means, (ii) determine whether the defect correction is an overcorrection, and (iii) generate a control signal for correction of the pixel signal if the pixel signal is the overcorrection; wherein, the control signal generated by the overcorrection calculation section is used to correct defects of the pixel signal, and the overcorrection calculation section includes defect distribution calculation means configured to (i) find a pixel defect count from a defect rate, and (ii) estimate a pixel defect count after the elapse of a predetermined time measured by the timing means.
