A method of reducing noise in an input image by setting, as a local window among color pixels included in the input image, a target pixel and neighboring pixels adjacent to the target pixel, determining color pixel values for the target pixel and each of the neighboring pixels included in the local window, generating local color average values are generated by averaging, color by color, the color pixel values, generating offset color pixel values by converting the color pixel values of the target pixel and the neighboring pixels based on the local color average values, and generating a compensated color pixel value of the target pixel by adjusting the color pixel value of the target pixel based on the offset color pixel values.

The disclosure is directed to transforming signals from one signal format to another signal format. For example, the format of a digital signal can change from storing video information in 12 bits of data to storing the video information in 32 bits of data. Other storage values and combinations can also be used. Since the number of bits available to store a portion of the video information can change when changing formats, a process is needed to translate or transform the video information appropriately. A transfer function utilizing a lookup table is used for the transforming. The lookup table utilizes a variable step size segmentation scheme that decreases the amount of lookup table storage space required and also decreases the number of estimation errors, i.e., interpolation errors. Estimation errors can occur when looking up a value not stored in the lookup table, and using neighboring values that are stored to estimate the value requested. In some applications, the log.sub.2 step size or total size values can be stored in the lookup table to further reduce the amount of storage space required. A video parameter, such as the type of video content and the display room ambiance, can also be used to select the balance between further decreasing the size of the lookup table and further decreasing the estimation errors.

A base image includes a B image signal in which ductal structure is brighter than mucous membrane and capillary vessels are darker than the mucous membrane. The B image signal is subjected to a frequency filtering process for extracting frequency components including the ductal structure and the capillary vessels. Thereby, a structure-extracted image signal, in which a pixel value of the ductal structure is a positive value and a pixel value of the capillary vessels is a negative value, is generated. Based on the structure-extracted image signal, a display controlling image to be used for enhancing display of the ductal structure and suppressing display of the capillary vessels is generated. The base image is combined with the display controlling image to obtain a display-controlled image in which the display of the ductal structure is enhanced and the display of the capillary vessels is suppressed.
