A method of measuring a display delay time includes a step where a display pattern displayed on a first display including i (i is a natural number greater than 2) display elements is switched to a display pattern other than the display pattern at every elapse of a pattern continuation time, and j (j is a natural number, 1&#x3c;j&#x3c;i) display elements brought into a first display state is switched at every elapse, a step where an image of the display pattern on the first display is captured, a step where the captured image is displayed on a second display, and a step where the display delay time from capturing the image on the first display to displaying the image on the second display is measured based on a difference between the display pattern on the first display and the display pattern on the second display.

Method of measuring display delay time, display device, and method of manufacturing display

A method of measuring a display delay includes a first step where a first display device performs a switching operation of switching a display pattern displayed on a display unit of the first display device, a second step where a first camera captures a first image and displays the first image in a live view mode, a third step where a second camera captures a second image containing the first image and records at least the first image contained in the captured second image while being correlated with information indicative of an imaging time when the second image is captured, and a fourth step where a display delay time of the first camera from the imaging of the first image to the display of the first image is deduced from the time indicated by the display pattern contained in the first image and the information indicative of the imaging time.

A method of measuring a shutter time lag of a camera includes: a first step of switching a display pattern of a display unit including i (i is a natural number greater than 2) display elements to a different display pattern at every time TP, and in the first step, the number of j (j is a natural number, and 1&#x3c;j&#x3c;i) display elements to be brought into a first display state among i display elements is switched at every time TP; a second step of capturing an image of the display unit in response to a shutter operation of the camera performed in synchronization with the switching operation; and a third step of deducing a shutter time lag taken from the shutter operation to the imaging of the display unit from the image captured by the camera.

An information processing apparatus includes a timing specifying unit that allows a user to specify a timing to execute video printing of a video file at least including first image data based on which a video frame is generated and second image data based on which a video frame is generated by additionally referring to image data of another video frame; a reference frame selecting unit that selects, on the basis of the timing specified by the timing specifying unit, the video frame generated from the first image data as a reference frame; an additional frame selecting unit that selects, on the basis of the reference frame selected by the reference frame selecting unit, one or a plurality of video frames generated from the first image data as additional frames; and an extracted image displaying unit that generates a plurality of extracted images on the basis of the first image data of the reference frame and the first image data of the additional frames and displays a group of the generated extracted images on a screen.

Information processing apparatus

An audio data processing device including: a first processor; and a second processor which is connected to the first processor wherein the first processor includes: an audio data acquisition which acquires audio data of digital data; an omitting section which omits a bit corresponding to low volume which is hard to be heard by human ears from the audio data; and a transmitter which transmits the audio data in which the bit corresponding to the low volume is omitted by the omitting section from the first processor to the second processor; wherein the second processor includes: a receiver which receives the audio data transmitted from the first processor; and a reproduction data generator which generates audio reproduction data necessary to reproduce the audio data based on the received audio data.

Audio data processing device including a judgment section that judges a load condition for audio data transmission

A system for printing photos, or images generally, includes a server computer that stores data representing a plurality of images in a photo database. A server web interface enables communication over the Internet, and the server computer includes an image print application that enables images to be printed using a client computer connected to the server web interface over said Internet. The server computer also includes an image enhancement module that enhances an image for printing. In response to a print request (over the Internet) from the client computer, the server computer sends image data and the image enhancement module to the client computer. The server computer activates the image print application to create print commands for a printer driver, and to create enhanced image data in the client computer with the image enhancement module prior to printing. The enhanced image data is removed from the client computer immediately following printing.
