Patent ID: 7796840

Claim:
An image processing apparatus having an image input unit and a detection unit for performing a process of detecting a predetermined target object in an image inputted from said image input unit, the image processing apparatus comprising: a size changing unit that sets a resolution of the target object to be detected by said detection unit; a resolution conversion unit that converts a resolution of said input image based on the resolution of the target object set by said size changing unit, wherein said detection unit performs said process of detecting the target object in the image whose resolution has been converted by said resolution conversion unit; a processing time acquisition unit that acquires a predicted processing time which is required for detecting the target object by said detection unit, based on the resolution of the target object set by said size changing unit and the resolution of the image which has been converted by said resolution conversion unit; and a display unit, wherein the resolution of the target object set by said size changing unit and the predicted processing time acquired by said processing time acquisition unit are displayed on said display unit, wherein each time the resolution of the target object is changed by said size changing unit, the display of the resolution of the target object and the predicted processing time is updated.
