Abstract: Selection candidates for number of imaging pixels and for an image compression rate are displayed in a two-dimensional arrangement on a setting screen for setting an image quality, and combinations of selectable number of image pixels and a compression rate can be presented to a user. An instruction for moving a cursor which displays a selected position on the screen is received, and a setting can be changed to a number of pixels and a compression rate which are pointed by the cursor after a position of the cursor is designated. More specifically, numbers of pixels to be selected are 2400×1800, 1280×960, and 640×480, and compression rates to be selected are Fine, Normal, and Basic. When the user selects the number of pixels, candidates of the selectable compression rate for the number of pixels are displayed.

Abstract: A video communication system may include a computer program that implements a feedback control process for automatically controlling a light. The feedback control process may include receiving an image from a video camera and determining an initial difference between the received image and a stored image. For example, the feedback control process may determine, on a pixel-by-pixel basis, whether the color and intensity of a facial region in the captured image is sufficiently close to the color and intensity of a facial region in the stored image. If the difference between the captured image and the stored image exceeds a threshold, the feedback control process includes transmitting an optimization instruction to the light. This optimization instruction, when performed by the light, decreases the difference between the received image and the stored image.

Abstract: Each pixel cell (12) of an image sensor (10) is made of a 4-Tr structure, in which only one Tr for resetting a column (X) is so added to an ordinary 3-Tr APS as to reset only an arbitrary pixel selectively, thereby to confine the pixel size. When a pixel signal is to be read, the period, for which the pixel signals composing an ordinary image of one frame are read, is finely divided so that the pixel signals of the pixels receiving an ID light for the period are read out bit by bit and repeatedly. At this time, for only the column being read, an electric current is fed to a read amplifier in the pixel cell (12) or a variable gain amplifier in an output unit (14), thereby to suppress the power consumption. As a result, a lower power consumption and a higher pixel formation can be attained in an image pickup device for picking up an image and for acquiring the ID information of a light beacon existing in the image pickup range.

Abstract: A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash.
