An article of headwear is disclosed that is formed of a plurality of panels. Digital media cases are inserted vertically into the opening between the front panel and the lateral supports. Also provided herein are methods of screening for modulators of EG-VEGF. In an image display section, pixels are arranged in a matrix, and sub-pixels in each of the pixels are aligned in a column direction of the matrix. The average value signal that has undergone the low-pass filter process is then subtracted from the input signal of each phase to extract the edge component of the input signal of each phase. When the face image is recognized by the face image recognition unit, the face image portion is cut out and stored as a separate image file.
