High CPU Utilization

[navi1084]

Dear All,
I am experimenting on a project which is connected to a camera by means of QTcpSocket. My program is to send a request for an image to camera and after receiving, process it and send another request.
The problem is in terms of CPU Utilization. My program takes 40 - 50% of CPU to execute. Is this deafault behaviour or is there any way to fix this issue so that program takes less CPU.

Hi, could you post some code, especially for the image processing part? (I'm just guessing that that's the most time consuming part, use a profiler to find out where the program really spends its time)

Precessing in the sense I am just displaying the image and as per the user perameter changing the image. example if user press b/w conversion then image will be converted into black and white.

even i have checked a Qt example affine in Qt\Demo\. If you run this appliaction atleast it will consume 25% of CPU. and on user action such as rotating etc it will consume 40 - 45%

so does your application continuously uses the cpu or just at image processing?

Can we just see the code? Or better yet, output from a profiler - this will tell you immediately what eats up most of the cpu.
