A tomographic-image pickup unit is controlled so as to capture a tomographic image in response to a signal input from a signal input unit. Then, a display unit is controlled so as to display the captured. tomographic image. An eyeground-image pickup unit is controlled so as to capture a two-dimensional image in response to a signal input from the signal input unit while the tomographic image. is displayed on the display unit. Therewith, the user can more easily perform imaging, and the time load on the subject is reduced.

Images are efficiently collected or delivered so that uncomfortable feeling given to users who view picked images picked up at vehicles and delivered by an image server is lessened. An image server is so constructed that the following operation is performed: the picked image of the surroundings of a vehicle, picked up with a camera mounted on the vehicle, and the image pickup information of the picked image, including information about the image pickup point, are stored on a storing medium; and picked images stored on the storing medium are delivered to users who view received picked images. One is selected from among picked images inputted from a vehicle with respect to each of areas to which the image pickup points of those picked images belong based on the image pickup information and a predetermined selection condition. The selected picked image is stored on the storing medium.

摘要:
Disclosed is a heat-sensitive recording material comprising a support and a heat-sensitive recording layer formed on the support, the heat-sensitive recording layer containing dye precursor-containing composite particles and a developer, the dye precursor-containing composite particles being obtained by dissolving a solute containing a dye precursor in a solvent containing a polyvalent isocyanate compound-containing polymerization component, emulsifying and dispersing the obtained solution in an aqueous medium, and then performing a polymerization reaction of the polyvalent isocyanate compound-containing polymerization component in the presence of polyethyleneimine having a molecular weight of 200 to 1,500. Also disclosed is a method of producing such a heat-sensitive recording material.

摘要:
The image bearing member to improve transfer efficiency at an occasion of transferring a toner image from the image bearing member. A rotational speed of a motor rotating the image bearing member in a short period and thereby disorder in a toner image can be restrained to reach a low level. On the other hand, circumferential velocity between the image bearing member and paper can be provided large. Therefore improvement in transfer efficiency can be designed.
