Abstract: A blurring process is performed on an addition area including a point light source area detected in an image to be processed so that the nearer to the circumference of the addition area, the higher the luminance value while an addition coefficient is being increased according to a distance from the center.

Abstract: An image processing apparatus includes an input unit configured to input image data, a detection unit configured to detect a region corresponding to local light in an image represented by the image data input by the input unit, and a processing unit configured to perform blur processing on the region corresponding to the local light and detected by the detection unit, wherein the processing unit varies, according to a position of the region corresponding to the local light and detected by the detection unit, an area on which to perform the blur processing.

Abstract: An upstream image processing apparatus determines, when geometric conversion is instructed, whether the result of downstream correction processing changes due to the geometric conversion, and if it changes, the apparatus changes the conversion to geometric conversion that does not cause a change in the correction result. Then, the geometric conversion is performed on a target image, and the resultant image is transmitted to a downstream image processing apparatus. Together therewith, instruction information indicating an instruction for correction processing and instruction information indicating geometric transformation processing for performing geometric transformation processing to the instructed degree are transmitted to the downstream image processing apparatus. The downstream image processing apparatus adds an instruction for image processing as appropriate, and thereafter transmits the resultant data to an image forming apparatus.

Abstract: According to this invention, image processes are classified into a plurality of categories, and the result of processes belonging to each category is written in an intermediate buffer prepared for the category. The order of categories is determined in advance, and an output from a process of a preceding category serves as an input to a process of a succeeding category. The preceding category includes image processes such as automatic correction requiring no quick response. The succeeding category includes image processes such as manual correction requiring a quick response.

Abstract: When a user inputs an image addition instruction from a UI input unit, a job registration unit registers a job corresponding to the instruction in a job list for each type of processing. When undo is input from the UI input unit, a current position pointer prepared for each type of processing returns to the immediately preceding job. When redo is input, the current position pointer moves to the immediately succeeding job. When a processing execution instruction is input, out of jobs registered in the job list, the job indicated by the current position pointer and preceding jobs are executed in a predetermined order.
