PPROBLEM TO BE SOLVED: To provide an image log generating device capable of generating an image log easy to read both of characters/pictures, using a simple configuration. PSOLUTION: A control portion 10 of an image log generating device directs a region extraction portion 104 to extract a text area representing characters and an image area representing pictures from an image data, and instructs an area determination portion 105 to determine a ratio of each region. Then, the control portion 10 controls a JPEG compression portion 106 to perform compression processing when the image data comprises mainly pictures, and controls a run length compression portion 107 to perform compression processing when the image data comprises mainly characters.
