Image freezing unit for obtaining still image at a precise timing from image data obtained by the imaging means |
摘要 |
A freezing unit of the present invention includes a color discrepant magnitude detection unit for accumulating the color corrected magnitude for each pixel output from a color discrepancy correction circuit, and detecting it as the color discrepant magnitude for one field. The freezing unit also includes a comparator circuit including a memory for storing the color discrepant magnitudes for sixteen fields, and a comparator for comparing the color discrepant magnitudes for sixteen fields to search a field with the least color discrepant magnitude, and a memory for storing sixteen field images. The freezing unit further includes a reference position selection circuit for selecting the reference position of the image by the freezing signal, and an image selection circuit for selecting the address of an image of a field with the least color discrepant magnitude.
