Document Type and Number:
Japanese Patent JP2023118139
Kind Code:
A
Abstract:
To accurately detect sudden noise generated in a photosensor in which a plurality of stages of line sensors are arrayed.SOLUTION: In an imaging device, on a TDI sensor, L stages of line sensors where N pieces of pixels are arrayed are arrayed. A data temporary storage part 2 includes a line memory part 21, and an A/D converter 22. The line memory part stores an electric signal based on electric charges accumulated in the TDI sensor 1. The A/D converter converts pixel data stored in the line memory part into digital pixel data, and outputs the converted digital pixel data. A sudden noise detection part 4 includes an outlier detection part 41, a majority processing part 421 constituting a sudden noise generation pixel coordinate detection part 42, and an output part 43. The outlier detection part detects the pixel supposed to have generated the sudden noise, as an outlier pixel. The sudden noise detection part executes majority processing based on an outlier detection result, and acquires a pixel coordinate where the sudden noise has been generated. The output part outputs a majority processing result to a display part 5.SELECTED DRAWING: Figure 1
