According to this invention, an image sensing apparatus capable of directly communicating with a printing apparatus guarantees that a printing apparatus with a photo-direct printing function normally prints even for a sensed image file containing raw image data and encoded image data such as JPEG obtained in a versatile encoding process. Hence, a digital camera can directly communicate with the printing apparatus. When the digital camera side selects a print target image and starts performing a print output, a print target image file is directly transmitted if the image file is a JPEG file. When the digital camera side selects a file containing raw and JPEG images, and the printing apparatus has a raw image printing function, the selected image file is directly output. When the file containing the raw and JPEG images is selected, and the printing apparatus does not have the raw image printing function, it is decided whether the size of the selected image file exceeds the upper limit size acceptable to the printing apparatus. If the file size exceeds the upper limit size, the raw image data is removed in order to reduce the file size, and the obtained data is transmitted to the printing apparatus. When an upper limit is not set, the selected image file is directly transmitted.

A password input and verification method is provided to prevent the disclosing of the password from peeping. The method is easy to learn, transparent to the users, and requires no hardware change and only minor software modification. The method allows a user to enter a much longer string of characters when he or she is asked for the password. The user is then authenticated if the actual password is embedded as a whole anywhere within the input string. The method also provides a mechanism called prohibition key. A prohibition key is a pre-determined character that, when present in the user input string, the user is not authenticated regardless of whether the actual password is contained in the input string or not.

The invention discloses a two-dimensional linear graphic coding counter-forgery method that can be printed on the surface of products directly. The method has the advantages of strong randomness, being difficult to be decoded, and suitability for small-sized products. The method includes generation, printing, and validation of linear graphs. As for the generation of linear graphs, a computer generates a code at least including linear angle information, and draws the linear corresponding with each code in the rectangle base frame; as for the identification of linear graphs, a picture collection device obtains the pictures of linear graphs, and obtains their black-and-white edge pictures after the pre-treatment, and then obtains each straight line's slope and interception information according to black-and-white edge pictures, and eventually calculates the corresponding code. The code is generated by the computer. At last, product information is validated through the code database of the validation system.

The PB Reader solves the problem that the e-reader presents: the e-reader has a non-paper screen and printed documents need assembly, binding, and page turning via hands.

This is an electronic, mechanical device that can quickly search, review and print documents and that has text-to-speech and remote control functionality. The unit is rectangular in shape similar as a traditional book, including a viewing window for reading and printing. The unit is fed by two paper-belt rollers, across which images and printed text are displayed. The two paper-belt rolls, which are held by two square axles that are driven by the stepping motor through multiple reduction gears. A pattern of round dots is printed on the bottom side of the paper belt, which can be decoded by a photoelectric sensor to take action of reeling pages. The signals control the stepper motor, allowing the reader to reel the page forward or backward, or jump directly to a specific position.

The second component of this invention is the designated printer. Its body shape is rectangular. The said printer can print any text files and photos from a computer directly onto the blank paper belt in the PB Reader by means of sensing the code on the paper belt.
