摘要： An image reading apparatus (9, 10) capable of shortening the reading processing time in image reading of high definition. In an image reading apparatus having a plurality of reading definition values, the state of a reading subject (13) is monitored with first definition. On the basis of a result of the monitoring, image reading (25) is conducted with second definition higher in definition than the first definition. A function (23, 35) of giving a stillness determination on an image of low definition is added. Switchover of the image to the high definition and read processing start are automatically carried out.

摘要： An image processing apparatus obtains a sum A of image data values of pixels in a template image, a sum B of squares of image data values of pixels in a template image, a sum C of image data values of pixels in a sub-image to be processed, of a search image, a sum D of squares of image data values of pixels in the sub-image of the template image, further obtains a threshold value F in advance by using the obtained values A, B, C and D, the number P of pixels in the template image, and the preset value E. Moreover, the apparatus obtains a square of each difference between an image data value of each pixel in the sub-image and that of a corresponding pixel in the template image, and performs cumulative addition for each obtained squares. If the result of cumulative addition exceeds the above-mentioned threshold value, the apparatus closes processing evaluation of a similarity between the sub-image and the template image. Furthermore, the apparatus recursively obtains a moving-average value of image data values of pixels in a rectangular region to be presently processed, by using a moving-average value for a rectangular region which was previously processed and image data read from a first memory and a second memory, each memory stores image data by one line pixels of the image, which include image data of pertinent pixels in the rectangular regions.
