— 38 —Blemish CompensationMultiple defective pixels that are not adjacent to each other can occur on conventional CMOSsensor cameras.This camera features a function that interpolates defective pixels using the surrounding pixels.Up to 256 pixels can be corrected for each of the three sensors. Pixel interpolation can beperformed via automatic detection or point-by-point manual settings.■ Automatic detectionAutomatic detection can only detect lit defective pixels (i.e., white blemishes).1 Shield the camera sensor.If a lens is attached, use the lens cap as a shield, for example.2 Configure the threshold level for defective pixel detection.Up to 256 pixels can be corrected.The threshold value is specified as a percentage.The default setting is "10" with 10% of the full scale (100%) specified as the thresholdvalue.3 Execute [BlemishDetect] to start automatic detection.After detection, the interpolation data is saved to the camera's internal memory.To check the number of interpolated pixels after automatic detectionYou can check the number of pixels interpolated via automatic detection by loading theBlemishNum data.■ Manual configuration1 Select the index in [BlemishCompensationIndex].You can select from 0 to 255. However, configure the indexes in order startingwith the smallest index. If you skip indexes while configuring settings,interpolation may not be performed.2 Specify the pixel points for interpolation using the[BlemishCompensationPositionX] and [BlemishCompensationPositionY] settings.You can configure values that are within the total effective pixel area. Specify pixels forwhich interpolation is not necessary as -1. If 0 is specified, the first line or first pixelwill be interpolated.3 Execute [BlemishStore].Blemish compensation data will be stored.NoteBlemishCompensationDataClear[BlemishCompensationIndex], you can return a specific pixelcorrection setting to the default value (storage not required).4 Set [BlemishEnable] to [True], and execute interpolation.If it is set to [False] , Blemish compensation is not effective.GO-5100MP-PGE
