Abstract: An information processing apparatus, an information processing method, and a storage medium are disclosed which determines whether or not to install program modules by acquiring environment information relevant to the types of the modules so that only those modules judged compatible with the environment of interest may be installed. This makes it possible for users to install only necessary program modules without becoming aware of specific conditions restricting the installation of the modules.

Abstract: A sensor head has a multiplicity of linear image sensors in correspondence with different radial directions of light emitted from a pixel in a pixel line of an LCD panel. The linear image sensors extends in the direction of the axis of an imaginary semi-cylinder. The linear image sensors have light receiving faces that are angularly spaced apart on an imaginary semi-cylinder, with their light receiving faces having normals passing through the axis of the imaginary semi-cylinder. Interposed in the space between the LCD pixel and the linear image sensors is an optical system having a multiplicity of light paths associated with respective angular components of the radiation emitted from the pixel line. Each of the light paths receives a predetermined angular component of light and transmits the light thus reveived to a corresponding one of the linear image sensors.

Abstract: A sensor head has a multiplicity of linear image sensors in correspondence with different radial directions of light emitted from a pixel in a pixel line of an LCD panel. The linear image sensors extends in the direction of the axis of an imaginary semi-cylinder and have their light receiving faces disposed on the imaginary surface of the imaginary semi-cylinder. with the normals to the light receiving faces passing through the axis of the imaginary semi-cylinder.
