A prism optical system including an optical low-pass filter disposed on an incident side of a luminous flux, and a prism arranged to perform a color separation to a plurality of color bands by an optical thin film, the prism optical system includes the optical low-pass filter disposed on an incident side of the prism, and at least two quarter-wave plates having a phase elimination function, and each disposed on one of an incident surface and an outgoing surface of the luminous flux of the optical low-pass filter. The prism optical system is configured to satisfy the following equation, |X1/X2|>0.7 where X1 is a phase elimination efficiency at 550 nm wavelength when the incident side quarter-wave plate is inserted between crossed nicols, and X2 is a phase elimination efficiency at 550 nm wavelength when the outgoing side quarter-wave plate is inserted between the crossed nicols.

An image pickup apparatus having a plurality of image pickup modes and a zoom lens for use with the image pickup apparatus is configured such that, even if the dimension of an effective screen region of an image pickup element changes as a result of changeover of the image pickup mode, the change of the angle of view is moderated and good aberration correction can be achieved in any of the image pickup modes.In an image pickup apparatus (1), an additional lens set (G5) having a positive refractive power is positioned most adjacent the image side with respect to a zoom lens (2) for movement to and from a position on an optical axis of the zoom lens. Upon changeover of an image pickup mode, the additional lens set is moved to or away from the position on the optical axis to reduce or extend the focal length range of the zoom lens thereby to moderate the variation of the angle of view caused by a difference in dimension of the effective screen region of an image pickup element (12) when any different image pickup mode is selected. Further, the movement of the additional lens set to or from the position on the optical axis is detected to set the states of components in accordance with any image pickup mode.

It is an object of this invention to display the marks obtained by a player corresponding to game scenes by switching between an analog score display and a digital point display. In this invention, a key input detecting means, detects keys input by the player and obtains key operation signals. A correct or incorrect answer determining means, determines whether the answer is correct or incorrect by comparing the key operation signals with the correct input patterns. A point/score calculating means, calculates the marks obtained by the player on the basis of the correct or incorrect answer determination. A point/score display switching means, generates video signals for displaying the marks obtained by the player corresponding to the game scenes, by switching between an analog score display and a digital point display.
