Title:
IMAGING DEVICE, IMAGE ANALYSIS SYSTEM, ENCODING METHOD, AND ENCODING PROGRAM
Document Type and Number:
Japanese Patent JP2023060547
Kind Code:
A
Abstract:
To reduce the amount of transmitted data.SOLUTION: An imaging device 100 includes an acquisition unit 120 that acquires a first image containing an object, and obtains the importance of a second image generated before the first image, the detection position of the second image, and information indicating a second detection area of the second image, a detection unit 130 that detects the object on the basis of the first image, an importance determination unit 140 that determines the importance of the first image to be a value smaller than the importance of the second image when the objects in the first image and the second image are the same, the first detection area in the first image is narrower than the second detection area, or the first detection area and the second detection area are the same, a coding determination unit 150 that determines a frame other than an intra frame as the first image when the importance of the first image is smaller than a second threshold, an encoding unit 160 that encodes the first image as a frame other than the intra frame, and a transmission unit 190 that transmits encoded data.SELECTED DRAWING: Figure 3
