An image capture apparatus includes a sensor unit having a photoelectric conversion element; a holding member having a first portion for holding an optical element, and a second portion extending in a direction orthogonal to an optical axis over the first portion and covering an outer circumference of the sensor unit; and an actuator for driving a driven member in order to perform a photographing-relevant operation. The actuator is disposed outside of the first portion, and the actuator is disposed within an area defined between a first axis and a second axis, wherein the first axis and the second axis represent straight lines passing through the optical axis and parallel with a narrow side and a wide side of the photoelectric conversion element, as viewed from an optical axis direction, respectively.

A scheme for obtaining an original image free from any dust or scratches on a film by scanning a film original or the like with visible light and infrared light has been proposed. This scheme suffers problems, i.e., a large memory size and long processing time since original image data obtained by infrared light must be stored. To solve such conventional problems, this invention provides, e.g., an image scanning apparatus which has a light source for emitting visible light and invisible light, scanning means for scanning an original image irradiated with light emitted by the light source, and control means for controlling the scanning means to scan the original image irradiated with the invisible light, and then to scan the original image irradiated with the visible light.

An image reading apparatus is constructed so that a film holder and an adapter that are accessories can be selectively mounted to a film scanner that serves as an original placing board. A cartridge containing a dedicated film can be inserted into and removed from the adapter. Image information is read from the film in the film holder or the film in the cartridge by moving the original placing board. Further, the film or the cartridge can be exchanged in a condition where the film holder or the adapter is mounted to the film scanner.

Image reading apparatus

In an image reading apparatus for reading an image recorded on a film, an amount of light being incident on a line sensor comprised in the apparatus and transmitted through the film is adjusted according to the image density of the film such that a relative speed between the film and the line sensor and the luminance of a lamp for irradiating light on the film are controlled.
