The processor enlarges a character size of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is less than a threshold value, and increases number of characters of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is greater than or equal to the threshold value. ## Claims ### Claim 1 An information processing apparatus comprising: a display controller configured to display, in a region, a text comprising a plurality of characters; and a processor configured to change a display magnification of the display controller in response to user operation, wherein the processor is configured to enlarge a character size of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is less than a threshold value, and the processor is configured to increase number of characters of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is greater than or equal to the threshold value. ### Claim 2 (depends on 1) The information processing apparatus of claim 1, wherein the processor is configured to reduce the number of characters of the text displayed in the region in correspondence with a decrease in the display magnification, if the character size or the display magnification is greater than or equal to the threshold value, and the processor is configured to reduce the character size of the text displayed in the region in correspondence with a decrease in the display magnification, if the character size or the display magnification is less than the threshold value. ### Claim 3 (depends on 1) The information processing apparatus of claim 1, further comprising a controller configured to set the threshold value, by user operation. ### Claim 4 (depends on 1) The information processing apparatus of claim 1, further comprising a touchpanel, wherein the processor is configured to change the display magnification, if the processor detects change of a distance between two contact points on the touchpanel. ### Claim 5 (depends on 1) The information processing apparatus of claim 1, wherein the processor comprises a controller configured to change the display magnification to an initial magnification, in response to first user operation. ### Claim 6 (depends on 5) The information processing apparatus of claim 5, wherein the display controller comprises a touchpanel, and the controller is configured to change the display magnification to the initial magnification, in response to first touch operation on the touchpanel. ### Claim 7 (depends on 1) The information processing apparatus of claim 1, wherein the processor is configured to enlarge or reduce the region and the text, with an aspect ratio maintained. ### Claim 8 (depends on 1) The information processing apparatus of claim 1, wherein the display controller is configured to display an electronic program guide. ### Claim 9 An information processing method comprising: displaying, in a region, a text comprising a plurality of characters; and changing a display magnification in response to user operation, wherein the changing comprises: enlarging a character size of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is less than a threshold value, and increasing number of characters of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is greater than or equal to the threshold value. ### Claim 10 A non-transitory computer-readable storage medium comprising a computer program configured to be executed by a computer comprising a display controller configured to display, in a region, a text comprising a plurality of characters, and a processor configured to change a display magnification of the display controller in response to user operation, the computer program comprising instructions configured to cause the computer to execute functions of: enlarging a character size of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is less than a threshold value; and increasing number of characters of a text displayed in the region in correspondence with an increase in the display magnification, if the character size or the display magnification is greater than or equal to the threshold value. ### Claim 11 An information processing system configured to receive a request from an information processing terminal comprising a display controller configured to display, in a region, a text comprising a plurality of characters, the system comprising: a first transmitter configured to transmit first display data, comprising the text in the region, to the information processing terminal, if a display start instruction is received from the information processing terminal; a second transmitter configured to transmit second display data comprising the region and the text that are enlarged, to the information processing terminal, if a first enlargement instruction is received from the information processing terminal configured to display the first display data; and a third transmitter configured to enlarge the region, and to transmit third display data comprising data of the enlarged region and data for increased number of characters in response to enlargement of the region to the information processing terminal, if a second enlargement instruction is received from the information processing terminal configured to display the second display data.
