Abstract: An improved acoustic characteristic adjustment device comprises signal processing units including high frequency convolution arithmetic sections, low frequency convolution arithmetic sections, and delay sections. The device further comprises: an operation section from which a listener inputs a target characteristic in order to adjust a desired acoustic characteristic; an impulse characteristic control section; and a delay time control section. The impulse characteristic control section calculates impulse response data to effect convolution arithmetics. The delay time control section calculates alignment delay times necessary for sounds emitted from the speakers to reach a listening position. The delay time control section also calculates correction times for compensating various phase deviations. Times obtained by correcting the alignment delay times with the correction times are set as the delay times of the delay sections, respectively.

Abstract: A display apparatus configured to add variations to displayed contents to prevent the user from getting bored and sufficiently utilize the characteristics of a display panel such as an organic EL display panel which excels in displaying a moving image. The display apparatus is suitable for use in an electronic equipment, and comprises a display panel for displaying images, a storage unit contained in the electronic equipment for storing display data representative of display images for display on the display panel, and a writing unit for writing display data into the storage device from the outside. In one embodiment, a device body is provided with a rewritable memory such as a flash memory to provide an environment in which previously provided data can be captured through the Internet, or images created by the user can be uniquely captured.
