Security camera system and image processing apparatus
First Claim
1. A security camera system comprising:
- a pixel array included by a plurality of imaging elements;
an image signal processor that performs various types of image processing on raw data including each pixel value from the pixel array; and
an image processing unit arranged between the pixel array and the image signal processor,wherein the image processing unit comprises an important area extraction circuit that receives the raw data from the pixel array with respect to each frame and divides an effective pixel area of the frame into an important area and an unimportant area, and transmits the raw data of the important area to the image signal processor;
wherein the image processing unit further comprises a data synthesis circuit that combines predetermined additional information and the raw data from the pixel array and transmits the resulting data to the image signal processor, andwherein, based on distinction information from the important area extraction circuit, the data synthesis circuit transmits the raw data of the important area to the image signal processor during a period corresponding to the important area in the transmission period of the frame, and transmits the predetermined additional information to the image signal processor instead of the raw data of the unimportant area during a period corresponding to the unimportant area.

Abstract
A security camera system capable of reducing an amount of information without degrading useful information is provided. The security camera system includes a pixel array, an image signal processor that performs various types of image processing on raw data including each pixel value from the pixel array, and a pre-stage processing unit arranged between the pixel array and the image signal processor. The pre-stage processing unit includes an important area extraction circuit that receives raw data from the pixel array with respect to each frame and divides an effective pixel area of the frame into an important area and an unimportant area, and transmits the raw data of the important area to the image signal processor.
