Image processing device, and image processing method

Abstract

An image processing device capable of effectively reducing power consumption and prolonging the service life is provided. A frame image of an imaging area imaged by a camera is input by an image input unit. An image processing unit is configured to process the frame image input to the image input unit and detect an object imaged in the frame image. In addition, the image processing unit is configured to determine a frequency of an operation clock according to the number of objects detected by the image processing unit.

Description

technical field [0001] The present invention relates to a technique for detecting a captured object by processing frame images of a shooting range captured by a camera. Background technique [0002] Conventionally, an image processing device has been provided that processes frame images of an imaging range captured by a camera, detects captured objects such as people and cars, and tracks the detected objects (see Patent Document 1, etc.). A conventional general image processing device, as shown in Patent Document 1, etc., generates a difference image (background difference image) between a frame image of a shooting range captured by a camera and a background image of the shooting range, two time-continuous The differential image of each frame image (inter-frame differential image), etc., to detect and track objects.

Problems solved by technology

Therefore, when the number of subjects captured in a frame image is relatively small, the image processor can process faster than necessary, and power consumption increases unnecessarily

In addition, the greater the power consumption, the greater the heat generation, so the life of the image processor is shortened
