摘要： The invention concerns a method of performing, by an image processing device, object detection in an image comprising: performing one or more tests of a test sequence for detection of a first object on pixels values of a plurality of at least partially overlapping sub-regions (310, 312, 314) of a first search window (108); generating a cumulative score based on results of said one or more tests on said plurality of sub-regions; comparing said cumulative score with a threshold value; and based on said comparison, selectively performing one or more tests of said test sequence on at least one further sub-region of said first search window, said at least one further sub-region at least partially overlapping each of said plurality of sub-regions.

摘要： The conversion device comprises an input for receiving data corresponding to an image to be displayed, said received data being in a JPEG decoder output data format and processing means for reconstructing and writing the image to be displayed into said image memory, in a display module expected input data format. The bandwidth of the image memory (MM) is greater than one byte. Said processing means are fully hardwired and comprises a first logic stage (LST1) for writing said received data byte by byte into an intermediate memory (ITM) at chosen addresses such that said written data form a sequence of data in said display module expected input data format, and a second logic stage (LST2) for reading said written data in said intermediate memory, forming successive packets of read data having a size corresponding to said bandwidth, and successively writing said packets into said image memory (MM) at chosen addresses such that said written packets form together all the lines of said image.
