    摘要: An image processing unit is provided which can solve a problem of a conventional image processing unit in that the control for coding image data is complicated and its circuit scale is large. The image pickup apparatus picks up an image of a subject and converts it to electric signals, thereby outputting image signals. An A/D converter A/D converts the image signals, and outputs them as image data. A fixed length coding circuit breaks down the image data into small unit blocks consisting of a predetermined number of pixels, and carries out fixed length coding after obtaining the average level of the pixel data in each unit block. An exposure controller calculates a luminance level of a whole set of pixel data in the unit blocks, and controls the exposure of the image pickup apparatus so that image data becomes a predetermined luminance level.

    摘要: A rewritable recording/display apparatus using a rewritable recording medium in which color development reaction occurs by thermal energy at a predetermined temperature, and in which a color extinguishing reaction occurs by thermal energy at a temperature lower than the color development temperature, and which is capable of repeatingly performing recording and erasing of images. The apparatus also has a color developing heating device for recording an image on the rewritable recording medium by heating the rewritable recording medium, and an erasing heating device for erasing the image after the image has been recorded. Thus, the apparatus is designed so as to have a recording section simplified and reduced in size, and to reduce the maintenance and running cost. A method of erasing a rewritable record enables images to be erased completely or suitably in terms of practice and enables formation of high-quality image after erasing of the previous image.
